POWER ADJUSTMENT

The power adjustment mechanism of the PA3500 allows the user to adjust the

penetration of the pin through the fixture ensuring a precise fastening. To operate the

power adjustment mechanism, move the scroll wheel which is situated on the PA3500

housing in the + or – direction to increase or decrease the power of the tool thus

adjusting the pin penetration.

1 = minimum power

3 = medium power

6 = maximum power

Note: Start with minimum power. If the fastener does not penetrate deep enough,

increase the power.

FASTENER FUNCTIONING

Prior to learning the safe operating procedures for this tool, it is important to understand

how a powder actuated fastener works. A powder actuated fastener is considered to be

a direct drive or forced entry type of fastener because it is driven directly into the base

material. The driving action causes tremendous forces to be applied to the fastener.

DEWALT powder actuated fasteners are specially designed and manufactured to

withstand the forces imposed during the driving operation. Only fasteners manufactured

or supplied by DEWALT should be used in this tool.

FUNCTIONING IN CONCRETE

The performance of a powder actuated fastener when installed into concrete or

masonry base materials is based on the following factors:

1. Strength of the base material

2. Hardness and concentration of the aggregate

3. Shank diameter of the fastener

4. Depth of embedment into the base material

5. Fastener spacing and edge distance

In addition to these factors, installation tool accessories such as a stop spall, which

reduces the tendency of the concrete surface to spall during the driving action, can

increase the performance of the fastener.

When a powder actuated fastener is driven into concrete, it displaces the volume of

concrete around the embedded area of the fastener shank. As this occurs, the concrete

directly surrounding the fastener is compressed and in turn presses back against the

shank of the fastener. Additionally, the driving action generates heat which causes

particles within the concrete to fuse to the shank of the fastener. This combination

of compression and fusion holds the fastener in the concrete base material. A similar

action occurs when fastening into block masonry.

Generally, the performance of the fastener in a given concrete strength will increase

with greater embedment depths in a certain range. Depending on the fastener style

DW2077_PA3500_manual_TRI.indd 3 2/9/18 8:54 AM

PA3500

EN 4

and base material strength, embedment depths range from 5/8" to 1-1/2". For depths

greater than this range, there is the possibility of fastener bending or fishhooking which

may decrease expected load capacities and create a safety hazard.

During the driving action, some localized surface spalling of the concrete may occur.

Normally, this is a surface effect which does not effect the performance of the fastener.

However, it may pose an aesthetic problem for exposed applications where a fixture is

not used. In cases such as this, two methods can be used to improve the appearance

of the fastening. A stop spall adapter mounted on the powder actuated tool can help to

reduce surface spalling. Another method used is to drive the fastener through a steel

washer to improve the appearance of the application.

FUNCTIONING IN STEEL

The load performance of a powder actuated fastener when installed into steel base

materials is based on the following factors:

1. Thickness of the steel

2. Tensile strength of the steel

3. Shank diameter of the fastener

4. Depth of point penetration through the steel

5. Fastener spacing and edge distance.

When a powder actuated fastener is driven into steel, it displaces the steel laterally

360˚ around the shank of the fastener. Since steel is an elastic material, it presses

back against the shank of the fastener to hold it in place. As the diameter of the

fastener shank is increased, the load capacity obtained will generally increase provided

the steel thickness is sufficient to accept the fastener. To further increase fastener

performance in steel, some fasteners have a knurled shank which allows the steel

to form a key lock into the grooves to provide higher capacities than those obtained

with a smooth shank. For optimum performance, the fastener point should completely

penetrate the steel. Normally, a minimum of 1/4" is allowed for the point length. An

increase in performance can be expected until the fastener no longer completely

penetrates through the steel. At this point, the elastic properties of the steel cause

a compression force to be developed at an angle against the fastener point which

reduces load capacity. In thicker steel base materials, adequate load capacities may be

obtained for applications in which the point of the fastener does not fully penetrate the

steel. Job site performance tests are recommended.

Fasteners should not be used in areas that have been welded or cut with a torch

as these procedures may have caused local hardening of the steel. Over driving of the

fastener should be avoided as the rebound created may reduce the load capacity or

cause damage to the fastener. When fastening into unsupported long steel members,

it may be necessary to provide support in the area of the fastening to prevent spring

action which can cause inconsistent penetration and a reduction in load capacity.

SUITABLE BASE MATERIAL

While powder actuated fasteners can be used successfully in concrete, certain masonry

materials, and A 36 steel, some materials are completely unsuitable. Fasteners should

never be fired into hard or brittle materials such as cast iron, tile, glass, or rock. These

materials can shatter easily resulting in a potential safety hazard. In addition, soft base

materials such as wallboard, plaster, or wood are not appropriate as the fastener could

pass completely through these materials. The user should never guess when fastening

into any base material. Failure to follow the recommended installation and safety

guidelines can result in severe injury or death to the tool operator and/or bystanders.

CENTER PUNCH TEST

A center punch test should always be performed to determine the suitability of the base

material for a powder actuated fastening. This test is relatively simple and can help

to insure a safe, successful fastening. Be sure to wear the appropriate eye protection

when performing this test. To begin, select the fastener to be used for the job. Then,

place the point of the fastener against the proposed base material. Strike the fastener

with a single hammer blow, then examine the point. If the point of the fastener is not

blunted and the base material has a clear point indentation, it is acceptable to proceed

with the first test installation.

Use of a powder actuated system is not recommended if the following occurs during

the center punch test:

1. The fastener point has been blunted. This indicates that the base material is

too hard.

2. The base material cracks or shatters. This indicates that the base material is

too brittle.

3. When using an average hammer blow, the fastener penetrates the base material

easily. This indicates that the base material is too soft.

FASTENER INSTALLATION REQUIREMENTS

It is important to understand the required minimum base material thickness

requirements along with the minimum spacing and edge distance requirements.

Failure to follow these requirements can result in an unsuccessful fastening and create

a safety hazard.

BASE MATERIAL THICKNESS

Concrete base material should be at least three (3) times as thick as the fastener

embedment penetration. If the concrete is too thin, the compressive forces forming at

the fasteners point can cause the free face of the concrete to break away. This can

create a dangerous condition from flying concrete and/or the fastener and also results

in a reduction of fastener holding power. For applications in the face shell of concrete

masonry block, select a fastener length which will not exceed the thickness of the

face shell.

FASTENER PENETRATION GUIDE

The following table lists typical embedment or penetration depths expected in the base

materials listed. The penetration will vary depending on the density of the material. This

table should be used as a guide since the consistency of these materials varies. When

in doubt, a job site performance test should be conducted.

DENSITY TYPICAL BASE MATERIAL PENETRATION

Soft Masonry Concrete Block 1" (26mm) -1-1/4" (32mm)

Average Concrete Poured Concrete 3/4" (19mm) - 1" (26mm)

Dense Concrete Pre-Stressed/Pre-Cast Concrete 5/8" (16mm) - 3/4" (19mm)

EDGE DISTANCE

Do not fasten closer than 3" (76mm) from the edge of concrete. If the concrete cracks,

the fastener may not hold. Closer edge distances for applications such as sill plates

may be permitted if specific fastener testing has been conducted.

SPACING

Setting fasteners too close together in concrete or masonry can cause cracking. The

recommended minimum distance between fasteners is 3" (76mm) center to center.

FASTENER LENGTH SELECTION IN CONCRETE

For permanent applications using pins in concrete, first determine the thickness of

the fixture to be fastened. To this, add the required embedment or penetration into

the base material. This will be the fastener shank length required. For applications

in the face shell of masonry block, select a fastener length which will not exceed the

thickness of the face shell.

For removable applications with threaded studs, the shank length required is

equal to the embedment depth required. To determine the minimum threaded length,

add the thickness of the fixture and the nut / washer thickness. The nut and washer

thickness is equal to the nominal thread diameter. Do not over tighten threaded parts.

Maximum tightening torque values are listed in the table below. Use of a nut setter

is recommended to reduce the possibility of over tightening the fasteners. For critical

applications, perform a job site test.

MAXIMUM TORQUE FOR 1/4” STUD MAXIMUM TORQUE FOR 3/8” STUD

2 ft.-lbs. or 2.7 Nm 4 ft.-lbs. or 5.4 Nm

INSTALLATION IN STEEL

The following guidelines are based on the installation of a fastener in ASTM A 36

structural steel with the point fully penetrating the steel member. Recommended steel

material thickness ranges from a minimum of 1/8" (3mm) to a maximum of 3/8"

(10mm). For use in higher strength structural steel, applications where the point does

not penetrate the steel member, or a thickness of steel greater than 3/8" (10mm),

job site performance tests are recommended.

BASE MATERIAL THICKNESS

Steel base materials should be a minimum of 1/8" (3mm) in thickness.

EDGE DISTANCE

For installations in A 36 steel, 1/2" (13mm) is the recommended minimum edge

distance.

SPACING

The recommended minimum distance between fastenings is 1-1/2" (38mm) center to

center for installations in ASTM A 36 steel.

FASTENER LENGTH SELECTION IN STEEL

For permanent applications when using pins in steel, first determine the thickness of

the fixture to be fastened. To this, add the thickness of the steel base material plus a

minimum of 1/4" (6mm) to allow for proper point penetration. This will be the minimum

fastener shank length required. Do not select a fastener length longer than that

required for the application.

An excessively long shank can burnish or polish the hole created in the steel

resulting in a reduction in load capacity.

For removable applications with threaded studs, the shank length required is equal

to the thickness of the steel base material plus a minimum of 1/4" (6mm) to allow for

proper point penetration. This will be the minimum fastener shank length required. Do

not select a shank length longer than that required for the application. An excessively

long shank can burnish or polish the hole created in the steel resulting in a reduction

in load capacity. To determine the minimum threaded length, add the thickness of the

fixture and the nut / washer thickness. The nut and washer thickness is equal to the

nominal thread diameter.

Do not over tighten threaded studs, the maximum tightening torque is listed in

the table below. Use of a nut setter is recommended to reduce the possibility of over

tightening the fasteners. For critical applications, perform a job site test.

the contents of this manual. You must be familiar with all functional and safety requirements of the tool. It is

your responsibility to obtain proper training and a DEWALT operator card prior to using this tool in compliance

with the current American National Standard A10.3 Safety Requirements for Powder Actuated Fastening

Systems and the Federal Occupational Safety and Health Administration Standards (OSHA). Existing state or

local regulations should also be followed. When using this tool, you must have the qualified operators card in

your possession.

Revocation of card - Failure to comply with any of the rules and regulations for safe operation of powder

actuated tools shall be cause for the immediate revocation of your qualified operator card.

The following is a summary of safety precautions to be followed when operating a DEWALT powder

actuated tool. Failure to follow these safety instructions can result in serious injury or death to operators

or bystanders.

PRIOR TO OPERATING THE TOOL

1. Warning signs should always be posted within the area in which a powder actuated tool is to be used.«

These signs should be at least 8" (203mm) x 10" (254mm) in size with boldface type that is not less

than 1" (26mm) in height. The sign should state “Powder Actuated Tool In Use”.

2. Approved eye protection should always be worn by operator or bystander, to protect their eyes from

flying particles. Hearing protection should always be worn by the operator and bystanders when using a

DW2077_PA3500_manual_TRI.indd 7 2/9/18 8:54 AM

PA3500

EN 8

powder actuated tool. Other personal safety protection as required should also be used.

3. Never modify or fabricate parts for use in your DEWALT tool. Use only DEWALT, loads, and tool parts.

4. Hands or other body parts must never be placed in front of muzzle/barrel. Accidental discharge can

cause piston and/or fastener to pass through the operator’s hand.

5. Never compress the tool against any part of the body. Serious injury or death may result in the event of

an accidental discharge.

6. Always point tool in a safe direction at all times.

7. Use the tool for its intended purpose only.

PREPARATION FOR LOADING THE TOOL

1. Tools must be checked prior to operating to make sure they are not fully or partially loaded with a

powder load or fastener.

2. To insure safe operation, perform the daily function test described in this manual. Be sure the tool is not

loaded prior to performing this test.

3. Do not operate this tool unless all its parts are in place and operating appropriately. Never attempt to use

a malfunctioning tool. Call 1-800-524-3244 for assistance.

4. Never guess about the suitability of a base material. If you are uncertain about the suitability of a base

material, perform a center punch test.

5. Do not operate the tool until you learn and understand the color code / numbering system used to

identify the power level of powder loads.

OPERATING THE TOOL

1. Only use fasteners and powder loads designed for this tool as supplied by DEWALT.

2. Do not use powder actuated tools in a flammable or an explosive atmosphere.

3. Do not fire a tool without a fastener. The piston will impact the work surface possibly causing serious

injury to the operator or bystanders along with damage to the tool.

4. Do not load the tool until you are ready to make a fastening. Check the power load level before inserting

it into the tool chamber.

5. Fastener must be loaded prior to loading the powder load, to prevent injury to operator or bystander in

the event of an accidental discharge.

6. Do not close tool against work surface. The tool should be manually closed, with hand away from

muzzle/barrel to prevent accidental discharge.

7. Hold the tool perpendicular to the work surface at all times. Use a spall guard wherever possible. This

will limit the possibility of fastener ricochet which could cause serious injury or death to the operator or

bystanders.

8. Always perform a test fastening with the lightest load level designed for use in the tool. If the lightest

load fails to set the fastener, try the next highest load until the proper level is attained. Failure to follow

this procedure may cause the fastener to be overpowered. If this occurs, the fastener may fully penetrate

the base material causing serious injury or death to someone. Overpowering the fastener can also

damage the tool, creating a safety hazard to both the operator or bystanders.

9. Do not fasten into cast iron, tile, glass, or other types of brittle materials. These materials can shatter

and create sharp fragments which may cause injury.

10. Do not fire tool within 3" (three inches) (76mm) of the edge of a concrete base material or within 1/2"

(one-half inch) (13mm) of the edge of a steel base material.

11. Do not attempt to install a fastener closer than 3" (three inches) (76mm) to another previously inserted

fastener in concrete or 1-1/2" (one and one-half inch) (38mm) in steel.

12. Do not fasten into a concrete base material less than 3 times as thick as the fastener penetration or into

a steel base material thinner than 1/8" (3mm).

13. Never attempt to install a fastener in a cracked or spalled area in concrete. Place fastener at least 3"

(three inches) (76mm) away from a spalled area to prevent the possibility of the fastener bending and

striking an operator or bystander.

14. Do not attempt to install fasteners in areas that have been welded or cut with a torch as these

procedures may have caused local hardening of the steel.

15. Do not fasten through a predrilled hole unless proper guidance is provided.

DW2077_PA3500_manual_TRI.indd 8 2/9/18 8:54 AM

PA3500

16. If you decide not to make a fastening after the tool has been loaded, you must always remove the

powder load first followed by the fastener.

17. Never attempt to override the safety features of this tool.

HANDLING THE TOOL AND POWDER LOADS

1. Never leave a loaded tool unattended. Once the tool is loaded, make the fastening immediately or unload

the tool.

2. Always unload the tool before work breaks, changing parts, cleaning or servicing, and when storing.

3. To prevent accidental discharge of loads, never carry the powder loads in the same container as the

fasteners or other hard objects.

4. Always store the powder loads in the containers provided or in an enclosure provided for them. Never

intermix the various power levels. Keep them segregated in clearly identified containers.

5. Powder loads should never be used in firearms. They are normally more powerful that the cartridges

supplied with the firearms.

6. Powder actuated tools and powder loads should always be stored under lock and key. Tools must be

unloaded when not in use.

TOOL MALFUNCTION

1. In the event that a load fails to discharge after the trigger is pulled, the tool must be kept depressed

against the work surface for a minimum of 30 (thirty) seconds in case of a delayed load discharge. Then

carefully remove the entire load strip. and dispose of it in a can of water or other nonflammable liquid.

Never attempt to force or pry a load out of a tool chamber.

2. Never discard unfired powder loads into a trash container.

3. Do not attempt to unload or disassemble a jammed, stuck or broken tool as improper handling may

cause it to discharge and strike operator and/or bystander. A jammed tool must be pointed in a safe

direction at all times. Tag the tool and lock it up. Call your DEWALT representative for proper assistance.

TOOL OPERATION

CAUTION: Be sure to read and understand all of the safety precautions and

training in this manual before attempting to operate the tool. (Check to be sure the

tool is not loaded, the piston moves freely within the barrel, and no foreign objects or

fasteners are in the barrel.) Perform the daily function test before using the tool.

OPERATION

1. Always load the fastener before inserting powder load to prevent injury to the

operator or bystanders in the event of an accidental discharge. Place the fastener,

point out, into the end of the guide until the fluted tip fits inside. Do not use

excessive force when inserting the fastener. If excessive force is required, stop

and determine why the fastener can not be inserted. Correct the problem before

proceeding.

Note: Do not use fasteners longer than 3" (76mm) as listed in the fastener selection

section of this manual. Pins longer than 2-1/2" (64mm) require pre-driving.

2. Always point the tool in a safe direction away from bystanders and the operator. In

one movement, slide the barrel forward then close it against the stop. The barrel

should be pulled fully forward to reset the piston for the next fastening. Loss of

power may result from an im properly positioned piston.

Do not attempt to close the tool by exerting force on the front of the barrel. Never

place your fingers or hands over muzzle end of the tool. The safe position for hands

and fingers are as shown in the diagram. Hands must never be placed in front of

the tool muzzle or barrel. In the event of an accidental discharge, the piston and/or

fastener can pass through the operator’s hand.

3. Insert the powder load strip into the bottom of the tool handle starting with the lowest

power level, 2/Brown. The strip should be inserted completely and should be flush

with the bottom of the handle. Always insert the strip from the bottom of the handle.

If this load does not fully set the fastener, try the next higher power level until the

proper level is found.

WARNING: Over driving or over powering a fastener can cause a safety hazard.

4. To make a fastening, place the tool against the work surface. Hold the tool firmly

with two hands and completely depress the barrel. Then squeeze the trigger. Always

hold the tool perpendicular to the work surface. Hold the tool firmly against the work

surface to avoid excessive recoil. Never depress the tool against anything except the

work surface.

Note: In the event that the load does not discharge after the trigger is pulled, continue

to hold the tool depressed against the work surface for at least 30 (thirty) seconds

in case of a delayed load discharge. Then carefully remove the entire load strip and

dispose of it in a can of water or other non flammable liquid. Never attempt to force or

pry a load out of a tool chamber. Do not discard unfired loads into a trash container.

5. To prepare for the next fastening, point the tool in a safe direction. Always insert a

new fastener before loading or advancing the powder load strip. Insert the fastener

as described in Step 1. Once the fastener is inserted, cycle the tool as described in

Step 2. Repeat this procedure for subsequent fastenings. When the ten load strip

has been completely fired, remove it by pulling it from the top of the tool body.

WARNING: Do not attempt to unload or disassemble a jammed, stuck or broken

tool as improper handling may cause it to discharge and strike the operator and/or

bystander. A jammed tool must be pointed in a safe direction at all times. Tag the tool

and lock it up. Call your DEWALT representative for proper assistance.

PROPER MAINTENANCE AND CLEANING

MAKE SURE THE TOOL IS NOT LOADED. BE SURE THE TOOL IS NOT HOT PRIOR TO ATTEMPTING

DISASSEMBLY OR CLEANING.

DAILY FUNCTION TEST

Check the functioning of the tool, without a powder load or fastener in the tool, by pushing down against

the work surface, pulling the trigger, and releasing the tool from the work surface. Function the unloaded

tool several times and insure that the breech parts and firing mechanism operate freely before fastening with

the tool.

Your DEWALT Authorized representative should be asked to assist the first time you disassemble

and clean your tool.

If you ever have any trouble reassembling the tool, or have any doubt about worn parts, call your DEWALT

Authorized Powder Distributor.

CLEANING

AIl parts should be cleaned with detergent oil and the wire brushes supplied with your tool kit. Remove heavy

dirt build-up with the brush. After cleaning with oil, all parts should be wiped thoroughly dry. Excess oil will

tend to collect dirt and dust. Wear eye protection when cleaning the tool. The piston rod, barrel assembly,

and receiver should all be cleaned of excess dirt on a daily basis. Check the condition of the piston for

damage from wear and deformation.

To maintain this tool in good working condition, it is necessary to disas semble and clean the entire tool if

dirt is evident in the breech face, or if the tool appears to lose power. All parts should be cleaned with oil and

wire brushes. Remove heavy dirt. All parts should be wiped thoroughly dry after cleaning with oil.

General tool mainte nance should be performed at six month intervals or more frequently as required by the

frequency of tool use.

REPLACING OR REPAIRING THE PISTON

The piston is an expendable part and must be replaced periodically. Typical signs of a

worn out piston are: breaking, bending or mushrooming.

Prior to servicing the tool make sure there is no powder load in the tool. Use caution

and do not lose or damage any tool parts.

1. Using a pin, lift the end of the annular ball spring and rotate toward the top of the

tool body. Pull the piston stop back and out of the tool.

2. Slide the piston guide and baseplate assembly out of the tool.

3. Using a fastener, pry the shear clip off the baseplate. Replace the shear clip if it is

damaged.

4. Remove the baseplate from the piston guide, then pull the piston out of the guide.

REASSEMBLY:

5. Tilt the baseplate and slide the fastener guide out. Press the guide out of the

baseplate using a piston if it does not slide out freely. Replace the guide if it is

damaged.

6. Clean the piston using a wire brush. Inspect it for worn or damaged piston ring,

chipped end, or bending. Apply lubricant to the piston shank to minimize piston

sticking from an overdrive con dition. Wipe the piston dry.

7. If a piston tip is damaged, it can be shortened a maximum of 0.20 inches (5mm).

The tip of the piston should be ground flat and at 90 degrees to the shank of the

piston. The cham fer of the piston must also be reground as shown.Piston grinding

should be performed by qualified per sonnel using the proper equipment.

8. Press the piston into the end of the piston guide. Be sure to push it all the way

back into the guide. Ensure piston is positioned correctly in piston guide.

9. Insert the fastener guide into the baseplate.

10. Align the groove in both the piston guide and baseplate. Slide the baseplate (with

fastener guide) onto the piston guide. Press the shear clip into place. Insert the

piston guide and baseplate assembly into the liner in the tool body. Be sure to align

the groove with the opening for the piston stop.

11. Replace the piston stop and rotate the annular spring into place.

Upon reassembly of the tool perform the following test. Depress the tool against a flat,

hard surface and pull the trigger. The barrel assembly should slide smoothly inside the

tool housing assembly. The firing pin should release after the trigger has been pulled.

CAUTION: THIS TEST SHOULD BE PERFORMED WITHOUT A PIN OR

POWDER LOAD IN THE TOOL.

AJUSTE DE POTENCIA

El mecanismo de ajuste de potencia de la PA3500 le permite al usuario ajustar el nivel de

penetración de la clavija a través del montaje de sujeción, lo que garantiza una fijación precisa. Para

operar el mecanismo de ajuste de potencia, mueva la rueda de desplazamiento que se encuentra

en la carcasa de la PA3500 en dirección + o - para aumentar o disminuir la potencia de la

herramienta. De este modo, se ajustará la penetración de la clavija.

1 = potencia mínima

3 = potencia intermedia

6 = potencia máxima

Nota: Comience con la potencia mínima. Si el fijador no penetra lo suficiente, aumente la

potencia.

FUNCIONAMIENTO DEL FIJADOR

Antes de aprender los procedimientos de operación segura para esta herramienta, es importante

entender cómo funciona un fijador accionado por pólvora. Un fijador accionado por pólvora se

considera un tipo de fijador de accionamiento directo o de entrada forzada porque se impulsa

directamente dentro del material de base. La acción de impulsión permite que se aplique una

gran cantidad de fuerza en el fijador. Los fijadores accionados por pólvora de

DEWALT

están

especialmente diseñados y fabricados para resistir las fuerzas impuestas durante la operación

de impulsión. En esta herramienta, solo se deben utilizar dispositivos fabricados o suministrados

por

DEWALT

FUNCIONAMIENTO EN CONCRETO

El rendimiento de un fijador accionado por pólvora cuando se instala en materiales de base de

concreto o mampostería depende de los siguientes factores:

1. Resistencia del material de base

2. Dureza y concentración del agregado

3. Diámetro del vástago del fijador

4. Profundidad de incrustación en el material de base

5. Espacio entre el fijador y la distancia al borde

Además de estos factores, el rendimiento del fijador puede aumentarse mediante accesorios

para la herramienta de instalación, como un bloqueo contra astillas, que reduce la tendencia a

romperse de la superficie de concreto durante la acción de impulsión.

Cuando un fijador accionado por pólvora es impulsado dentro del concreto, este desplaza

el volumen de concreto alrededor del área incrustada del vástago del dispositivo. Cuando esto

ocurre, el concreto que rodea el fijador se comprime y, a su vez, se presiona contra el vástago.

Además, la acción de impulsión genera calor y esto hace que las partículas dentro del concreto

se fusionen con el vástago del dispositivo.

Esta combinación de compresión y fusión mantiene el fijador dentro del material de base.

Una acción similar ocurre cuando se instala en mampostería de bloques.

ES 20

Por lo general, el rendimiento del fijador en una determinada resistencia del concreto

aumentará si se utiliza una mayor profundidad de empotramiento en un cierto rango. Según

el estilo del fijador y la resistencia del material de base, la profundidad de empotramiento va

desde5/8" a 1-1/2". Si empleará profundidades superiores a este rango, existe la posibilidad

de que el fijador se curve o se doble en la punta, lo que puede disminuir la capacidad de carga

esperada y crear un riesgo de seguridad.

Durante la acción de impulsión, puede producirse un astillado localizado de la superficie en

el concreto. Normalmente, este es un efecto de la superficie que no afecta el rendimiento del

fijador. Sin embargo, puede plantear un problema estético para aplicaciones expuestas en las

que no se utiliza un accesorio. En casos como este, se pueden usar dos métodos para mejorar

la apariencia de la fijación. Un adaptador de bloqueo contra astillas montado en la herramienta

accionada por pólvora puede ayudar a reducir el desprendimiento de la superficie. Otro método

utilizado consiste en impulsar el fijador a través de una arandela de acero para mejorar la

apariencia de la aplicación.

FUNCIONAMIENTO EN ACERO

El rendimiento de la carga de un fijador accionado por pólvora cuando se instala en materiales

de base de acero depende de los siguientes factores:

1. Espesor del acero

2. Resistencia a la tracción del acero

3. Diámetro del vástago del fijador

4. Profundidad de penetración de la punta a través del acero

5. Espacio entre el fijador y la distancia alborde

Cuando un fijador accionado por pólvora se instala en acero, el acero se desplaza lateralmente

360˚ alrededor del vástago del dispositivo. Como el acero es un material elástico, se presiona

contra el vástago del fijador para mantenerlo en su lugar. A medida que aumenta el diámetro

del vástago del fijador, también suele aumentar la capacidad de carga obtenida siempre que

el espesor del acero sea suficiente para soportar dicho dispositivo. Si se desea aumentar aún

más el rendimiento del fijador en el acero, algunos dispositivos tienen un vástago estriado

que permite que el acero forme un bloqueo de seguridad en las ranuras para proporcionar

capacidades superiores a las obtenidas con un vástago liso. Para obtener un rendimiento

óptimo, la punta del fijador debe penetrar por completo en el acero. Normalmente, se deja un

mínimo de 1/4" para la longitud de la punta. Se puede esperar un aumento en el rendimiento

hasta que el fijador ya no penetre por completo a través del acero. En este punto, las

propiedades elásticas del acero hacen que se desarrolle una fuerza de compresión en ángulo

contra la punta del fijador, lo que reduce la capacidad de carga. En materiales de base de

acero más grueso, se pueden obtener capacidades de carga adecuadas para aplicaciones en

las que la punta del fijador no penetra por completo en el acero. Se recomiendan pruebas de

rendimiento en el lugar de trabajo.

Los fijadores no deben usarse en áreas que hayan sido soldadas o cortadas con un soplete,

ya que estos procedimientos pueden haber generado un endurecimiento localizado del acero.

No debe emplear un nivel excesivo de impulsión para el fijador, ya que el rebote creado puede

reducir la capacidad de carga o causar daños en el dispositivo. Cuando se realice una fijación en

componentes de acero largos y sin soporte, tal vez sea necesario proporcionar soporte en el área

de la fijación, ya que la acción de rebote puede hacer que la penetración no sea uniforme y se

reduzca la capacidad de carga.

MATERIAL DE BASE ADECUADO

Mientras que los fijadores accionados por pólvora se pueden usar sin problemas en bases

de concreto, algunos materiales de mampostería, el aceroA36 y ciertos otros materiales

son completamente inadecuados. Los fijadores nunca se deben instalar en materiales duros

o quebradizos, como hierro fundido, azulejos, vidrio o piedra. Estos materiales pueden

desmenuzarse fácilmente y generar un posible peligro de seguridad. Además, los materiales de

base blandos —como los paneles de revestimiento, el yeso o la madera— no son apropiados,

ya que el fijador podría atravesarlos por completo. El usuario nunca debe hacer conjeturas

cuando realice un trabajo de sujeción en cualquier material de base. Si no se siguen las pautas

de seguridad e instalación recomendadas, se pueden producir lesiones graves o la muerte del

operador de la herramienta u otras personas.
