warnings and precautions, operating, inspection and maintenance

instructions. When using this tool, basic precautions should

always be followed to reduce the risk of personal injury and/or

damage to the equipment. Note that when this manual refers to a

part number, it refers to the parts list included.

WORK AREA

1. Operate in a safe work environment. Keep your work area

clean and well lit. Do not use in damp or wet locations and

do not expose this tool to rain. Do not use in the presence

of ﬂammable gases or liquids.

2. Keep anyone not wearing appropriate safety equipment

away from the work area. Distraction can cause you to

lose control.

3. Store unused equipment. When not in use, tools must be

stored in a dry location to prevent rust. Always lock up tools

and keep them out of reach of children.

PERSONAL SAFETY

1. Dress properly, wear protective equipment. Use breathing, ear,

eye, face, foot, hand and head protection. Always wear ANSI

approved impact safety goggles, which must provide both

frontal and side protection. Protect your hands with suitable

gloves. Wear a full face shield if your work creates metal ﬁlings

or wood chips. Protect your head from falling objects by wearing

a hard hat. Wear an ANSI approved dust mask or respirator

when working around metal, wood and chemical dusts and mists.

Wear ANSI approved earplugs. Protective, electrically non-

conductive clothes and non-skid footwear are recommended

when working. Wear steel toed boots to prevent injury from

falling objects.

2. Do not over reach; keep proper footing and balance at all

times. Proper footing and balance enables better control of

the tool in unexpected situations.

3. Keep any articles of clothing, jewelry, hair etc. away from

moving parts. These can be caught in moving parts, resulting

in damage to the tool and/or serious injury.

4. Stay alert, watch what you are doing and use your common

sense. Do not operate any machine or tool when you are

tired, under the inﬂuence of drugs, alcohol or medications.

5. Use clamps or other practical ways to secure and support

the work piece to a stable platform. Holding the work piece

by hand or against your body is unstable and may lead to

loss of control.

6. Do not allow the spray to strike you and do not spray

toward people or animals. Do not spray the tool itself or any

electrical source.

SPECIFIC SAFETY PRECAUTIONS

1. Never touch the moving parts or the blade during use.

2. Do not start the saw with the blade in contact with any

surface. The sawing action will cause the saw to bounce

violently and could cause injury. Let the tool reach it’s full

speed before starting to cut.

3. Check the blade carefully for cracks and damage before use.

If cracked or damaged, replace it immediately.

4. Never attempt to cut with the tool held upside down in a

vise. This will lead to serious injury.

5. Be sure the motor is reaching the full speed before starting

cutting work.

6. It is extremely dangerous to point the cutting surface toward

any person.

7. Do not apply side pressure to the saw blade. Support the

work piece to prevent it from sagging towards the blade

while being cut. There is an increased chance of damage to

the blade when pressure is applied to the sides.

8. The temperature of the machine will increase during the

operation. Keep the working area well aerated to decrease

the temperature.

9. Frequently clean dust from beneath the tool. Pressurized

air is ideal.

6 For technical questions call 1-800-665-8685

V 3.0 Reciprocating Air Saw 8344129

10. Protect yourself by against electric shock. When cutting

wherever “live” electrical wires may be encountered, hold

the tool only by the plastic handle and the rubber grip at

the front of the tool to prevent electric shock. Do not touch

any metal parts of the tool. If you contact a live wire, the

exposed metal of the saw becomes live as well, and can

shock the operator.

11. Avoid overloading your saw. Do not force the tool, otherwise

it will become hot and lose efﬁciency. Running it free

of load for a minute or two will allow it to cool itself to

normal temperature.

12. Before using this tool, make sure you know the area/material

you are working in/on. Make sure you do not accidentally

puncture pipes, pressurized containers or electrical cables.

When cutting wood, look for and remove all nails and staples

from lumber before cutting.

13. Use an appropriate dust respirator when working for an

extended period of time. This will help prevent breathing in

the ﬁne dust created while sanding.

CAUTION! Some wood contains preservative such as copper

chromium arsenate (CCA), which can be toxic. When working on

these materials extra care should be taken to avoid inhalation and

minimize skin contact.

TOOL USE AND CARE

1. Use the right tool for the job. Do not attempt to force a small

tool or attachment to do the work of a larger industrial tool.

The tool will perform better and more safely at the task for

which it was intended. Do not modify this tool or use for a

purpose for which it was not designed.

2. Securely hold this tool using both hands. Using tools with

only one hand can result in loss of control.

3. Maintain tools with care. Keep tools clean, sharp and in

good condition for a better and safer performance. Follow

instructions for lubricating and changing accessories.

Inspect tool ﬁttings, alignment and hoses periodically and, if

damaged, have them repaired by an authorized technician

or replaced. The handles must be kept clean, dry and free

Visit www.princessauto.com for more information 7

8344129 Reciprocating Air Saw V 3.0

from oil and grease at all times. A properly maintained tool

reduces the risk of binding and is easier to control. Sharp

tools are safer than tools which have become dull because

you do not have to apply excessive amounts of force to

make your cuts. Applying excessive force can lead to slips

and damage to your work or personal injury.

4. Remove adjusting keys and wrenches. Check that keys

and adjusting wrenches are removed from the tool or

machine before connecting it. A wrench or key that is left

attached to a rotating part of the tool increases the risk of

personal injury.

5. Avoid unintentional starts. Be sure that the throttle/ignition

switch is in neutral or OFF position when not in use and

before connecting it to any power/air source. Do not carry

the tool with ﬁngers near or on the switch.

6. Only use the lubricants supplied with the tool or speciﬁed by

the manufacturer. Other lubricants may not be suitable and

may damage the tool or even make the tool explode.

7. When not in use for an extended period, apply a thin coat of

lubricant to the steel parts to avoid rust.

8. Maintain label and name plate on the tool. These carry

important information. If unreadable or missing, contact

Princess Auto for a replacement.

AIR SOURCE

1. Disconnect air supply. Disconnect tools from air pressure

source when not in use, before cleaning, servicing or

changing a piece or accessory. After disconnecting,

discharge any residual air pressure.

2. Do not use tools if the trigger switch does not function

properly. Any tool that cannot be controlled with the

ON/OFF switch is dangerous and must be repaired.

3. Use proper size and type of air pressure line and ﬁttings.

The recommended air line for a tool with a 1/4 in. inlet is

3/8 in. I.D.

4. Always verify prior to using a tool that the air source has

been adjusted to the rated air pressure or within the rated

air-pressure range. Over pressurizing a tool may cause

bursting, abnormal operation, breakage of the tool or serious

injury to persons. Use only clean, dry, regulated compressed

air at the rated range as marked on the tool.

5. Never use pure oxygen, carbon dioxide, combustible gases

or any bottled gas as an air source for a tool. Such gases

are capable of causing an explosion and serious injury to

persons. Do not use an air source besides an air compressor

to power this tool.

6. Always use an air regulator, an in-line ﬁlter and a moisture

trap in your compressed air system. These accessories will

increase the tool’s life and keeps the tool in good working

condition. See the diagram above for recommended

components of an air line.

7. Drain the air tank daily. Water in the air line will damage

the tool.

8. Clean air inlet ﬁlter weekly.

9. Avoid using an unnecessarily long air hose. Choose a hose

that is appropriate for the situation, as a hose that is too

long and running across the ﬂoor can be more dangerous

than helpful.

10. Keep hose away from heat, oil and sharp edges. Check hose

for wear, and make certain that all connections are secure.

11. Always carry a tool by its handle, never carry the tool by the

air hose.

Visit www.princessauto.com for more information 9

8344129 Reciprocating Air Saw V 3.0

12. Line pressure should be increased to compensate for

unusually long air hoses (over 8 metres). The hose diameter

should be 3/8 in. l.D.

13. Air tool CFM consumption ratings are based upon a

25% duty cycle. If you require continuous duty, a larger

compressor will be required (eg. 4.0 CFM tool at continuous

duty requires 16.0 CFM to function at maximum torque).

LUBRICATION (AIR TOOLS)

An automatic in-line

ﬁlter-regulator-

lubricator is

recommended as it

increases tool life

and keeps the tool in

sustained operation.

The in-line lubricator

should be regularly

checked and ﬁlled with

air tool oil.

Proper adjustment of

the in-line lubricator is

performed by placing

a sheet of paper next

to the exhaust ports

and holding the throttle

open approximately 30

seconds. The lubricator

is properly set when a

light stain of oil collects on the paper. Excessive amounts of oil

should be avoided.

In the event that it becomes necessary to store the tool for an

extended period of time (overnight, weekend, or longer), it should

receive a generous amount of lubrication at that time. The tool

should be run for approximately 30 seconds to ensure oil has

been evenly distributed throughout the tool. Store it in a clean and

dry environment.

1. All air tools are packed in grease to prevent corrosion of

internal parts during shipping and storage. We recommend

you clean this out to have optimum performance from your

new air tool. Add a generous amount of air tool oil in the air

inlet, then run the tool under no load until exhaust is clear to

remove packing grease. For future maintenance, add only

one or two drops of oil daily.

2. It is important that the tool be properly lubricated by

keeping the air line lubricator ﬁlled and correctly adjusted.

Without proper lubrication the tool will not work properly

and parts will wear prematurely.

3. Use the proper lubricant in the air line lubricator. The

lubricator should be of low air ﬂow or changing air ﬂow

type, and should be kept ﬁlled to the correct level. Use only

recommended lubricants, specially made for pneumatic

applications. Substitutes may harm the rubber compounds in

the tools O-rings and other rubber parts.

IMPORTANT! If a ﬁlter/regulator/lubricator is not installed on the

air system, air operated tools should be lubricated at least once

a day or after 2 hours work with 2 to 6 drops of oil, depending

on the work environment, directly through the male ﬁtting in the

tool housing.

WARNING! NEVER use WD-40 to clean or lubricate your air tool.

WD-40 is a solvent that will break down the internal grease and

cause the air tool to seize up.

VIBRATION PRECAUTIONS

This tool vibrates during use. Repeated or long-term exposure

to vibration may cause temporary or permanent physical injury,

particularly to the hands, arms and shoulders.

1. Anyone using vibrating tools regularly or for an extended

period should ﬁrst be examined by a doctor and then have

regular medical check ups to ensure medical problems are

not being caused by or worsened from tool use. Pregnant

women or people who have impaired blood circulation to the

hands, past hand injuries, nervous system disorders, diabetes

or Raynaud’s Disease should not use this tool. If you feel any

medical symptoms related to vibrations (such as tingling,

numbness, and white or blue ﬁngers), seek medical attention

as soon as possible.

2. Do not smoke during use. Nicotine reduces the blood

ﬂow to the hands and ﬁngers, increasing the risk of

vibration-related injury.

3. Wear suitable gloves to reduce the vibration effects on

the user.

4. Use tools with the lowest amount of vibration when there is

a choice between different processes.

5. Do not use for extended periods. Take frequent breaks when

using this tool.

6. Let the tool do the work. Grip tool as lightly as possible

(while still keeping safe control of it).

7. To reduce vibrations, maintain tool as explained in this

manual. If abnormal vibrations occur, stop using this

tool immediately.

8. This tool will not stop moving immediately. Do not lay the

tool down or leave it unattended until it has come to a

complete stop. A part that is moving could make the tool

jump or grab a surface and pull the tool out of your control.

OPERATION

CUTTING

• Use a sharp blade especially designed to cut the material you

are working with.

• It is recommended you use a cutting ﬂuid on the metal

surface to avoid heat build up.

• When cutting metallic material with this tool, be sure to use a

ﬁne tooth blade.

• To ensure safe operation adjust the motor speed to a slower

setting by adjusting the variable speed dial to the lower end

of the speed range.

1. Before starting the cut, clearly mark the line of cut.

2. Install the correct blade for the material being cut. Adjust the

speed of the blade as necessary.

NOTE: In general, coarser blades are for wood, plastics, and

composites, and ﬁner blades are for cutting metal. Cracking,

shattering or vibrations may indicate you need a ﬁner blade or

higher speed. If the blade overheats or clogs, it may indicate you

need a coarser blade or slower speed setting. Replace blades

when they become dull. Dull blades will produce poor results and

may overheat the saw.

3. Connect the tool to it’s power source and turn it on.

4. Allow the saw to reach maximum speed.

5. Set the shoe against the workpiece.

6. Start cutting the material. Do not force it. Use only enough

pressure to keep the saw cutting.

7. When ﬁnished, turn off the tool.

ADDING OR CHANGING BLADES

Warning! Always disconnect the Saw from the air source before

adding or changing blades. After disconnecting the Saw from

the air compressor, there could still be enough air pressure to

activate the Saw. Always position the Saw safely and activate the

Throttle Lever repeatedly to make sure all of the air is expended.

1. The Blade Guard may be removed when replacing blades,

but it must always be on during operation. Using the Saw

without the Blade Guard can result in severe injury. To

remove the Blade Guard, loosen and remove the two Set

Screws. When replacing the Blade Guard, place it in the slots

and tighten the Set Screws.

2. To change blades, ﬁrst remove the Chuck Cover by removing

the Screw. Swing the Chuck Cover back on its hinge.

3. Loosen the two Set Screws inside, until the blade can be

removed. Replace with a new blade and tighten the Set

Screws. Replace the Chuck Cover and carefully tighten the

Screw. Do not overtighten the Screw or you may break the

plastic Chuck Cover.

Note: Never use a dull, bent, or cracked blade. Check that the

blade and blade guard are tight before each use.

MAINTENANCE

WARNING: Disconnect tool from air supply before changing

accessories, servicing or performing maintenance. Replace or

repair damaged parts. Use genuine parts only. Non-authorized

parts may be dangerous.

1. Lubricate the reciprocating air saw daily with a few drops of
