SPECIFIC SAFETY PRECAUTIONS

WARNING! DO NOT let comfort or familiarity with product (gained

from repeated use) replace strict adherence to the tool safety rules.

If you use this tool unsafely or incorrectly, you can suffer serious

personal injury.

1. Use the correct tool for the job. This tool was designed for a

specific function. Do not modify or alter this tool or use it for an

unintended purpose.

2. Do not use the tool if any parts are damaged, broken or misplaced.

Repair or replace the parts.

3. Before using this tool, make sure you know the work area and

material you are working on. Make sure you do not accidentally

puncture pipes, pressurized containers or electrical cables.

4. Keep hands and other body parts away from the chisel to avoid injury.

5. Only use with accessories rated to handle the forces exerted by

this tool during operation. Accessories not designed for the forces

generated may break and forcefully launch pieces.

6. The chisels will become hot while chipping. Allow the chisels to

completely cool before touching.

7. When chipping in a potentially explosive environment, use a spark

resistant chisel (usually made of beryllium copper).

8. Replace chisels that are worn or blunt at the cutting edge or shank. A

damaged chisel may damage the air hammer, reduce efficiency and

increase vibration. A chisel that breaks during use can cause an injury.

9. Do not store chisels below 0°C (32°F). Freezing temperatures may

cause hardened steel to become brittle. A brittle chisel may shatter

or break and cause an injury.

10. Do not cover the air vents.

AIR TOOL PRECAUTIONS

1. Use only clean and dry compressed air as a power source.

Contaminated or moist air will gradually damage the tool.

2. Install an in-line shutoff valve or regulator to allow immediate control

over the air supply in an emergency, even if a hose is ruptured.

8844177 Short Barrel Air Hammer V1.0

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

3. Discontinue tool use if it does not work properly or air is leaking.

Tag or mark the tool as ‘defective’ or ‘out of service’ until repaired.

4. Check the manufacturer’s maximum pressure rating for air tools

and accessories. Compressor outlet pressure must be regulated to

never exceed the maximum pressure rating of the tool (see

Specifications). Exceeding the maximum PSI rating can create a

bursting hazard, causing injury and property damage.

5. Attach all accessories properly to the tool before connecting the air

supply. A loose accessory may detach or break during operation.

6. Never use oxygen, combustible gas or any other bottled gas as a

power source. Any power source other than an air compressor

could cause an explosion and serious personal injury.

7. Turn OFF the valve and discharge any remaining air pressure after

each use or before adjusting the tool.

8. Do not leave the air tool unattended with its compressed air supply

on. Turn off the compressed air supply and bleed the air tool of any

remaining compressed air before leaving the air tool unattended.

9. Serious injury may occur from loose debris being propelled at high

speeds from the compressed air stream. Always wear OSHA approved

safety glasses to protect the eyes during operation of the air compressor.

10. Always turn off the air compressor and drain tank pressure

completely before attempting maintenance or attaching air tools.

Release pressure slowly from the system.

11. Serious injury or death may occur from inhaling compressed air.

The air stream may contain carbon monoxide, toxic vapors or

solid particles. Never inhale compressed air directly from the

pump or air tool.

POWER TOOL PRECAUTIONS

1. Do not use any power tool with a malfunctioning power switch or

control. A power tool that fails to respond to the controls is dangerous

and can cause an injury. A qualified technician must repair and verify

the power tool is operating correctly, before it can be used.

2. Avoid unintentional starts. Ensure the switch is off when connecting

to the power source.

3. Disconnect the power source before installing or servicing the tool.

4. Never force the tool. Excessive pressure could break the tool,

resulting in damage to your workpiece or serious personal injury.

Excessive pressure is the cause if your tool runs smoothly under no

load, but roughly under load.

5. Only use an accessory that exceeds the Beats Per Minute rating

(see Specifications). Ensure the accessory is tightly installed.

6. Before using the tool on a workpiece, test the tool by running it at

the highest no load speed for at least 30 seconds in a safe

position. Stop immediately if there is any abnormal vibration or

wobbling. Check the tool to determine the cause.

7. Never touch the tool accessory or workpiece during or immediately

after use. They may be hot and could inflict a burn injury.

8. Never use a tool with a cracked or worn tool accessory. Change

the tool accessory before using it.

9. Do not place the tool down until the tool’s accessory has stopped

moving. The accessory may catch the surface of work material

and wrench itself free, causing injury to the user or others in the

work area.

10. Hold the tool by the insulated gripping surfaces when performing

an operation where the tool may contact hidden electrical wiring.

The tool’s exposed metal surfaces may convey a shock to the

operator from a ‘live’ wire.

11. Gum and wood pitch hardened on an accessory slows the tool and

increases the potential for kickback. Remove the accessory from

the tool, then clean it with gum and pitch remover, hot water or

kerosene. Never use gasoline. Allow to dry before use. Discard the

accessory if the gum or pitch cannot be removed.

AIR HOSE PRECAUTIONS

1. Inspect the tool's air hose for cracks, fraying or other faults before

each use. Discontinue use if the air hose is damaged or hissing is

heard from the air hose or couplers. Replace the defective air hose.

2. Do not allow people, mobile equipment or vehicles to pass over the

unprotected air hose. Position the air hose away from high traffic

areas, in a reinforced conduit or place planks on both sides of the

air hose to create a protective trench.

3. Prevent damage to the air hose by observing the following:

3.1 Never carry the tool by the air hose.

3.2 Keep the air hose behind the tool and out of the tool's work path.

3.3 Keep the air hose away from heat, oil, sharp edges or moving

parts.

3.4 Do not wrap the air hose around the tool as sharp edges may

pierce or crack the air hose. Gently coil the hose and either

hang on a hook or fasten with a device to keep hose together

when storing.

4. A damaged or disconnected air hose under pressure may whip

around and inflict personal injury or damage the work area. Secure

the compressor's air hose to a fixed or permanent structure with

clamps or cable ties.

COMPRESSOR/TANK PRECAUTIONS

DANGER! Do not use an air tank beyond its expiration date. A

tank rupture or explosion may kill or cause a serious injury to

yourself or a bystander. Disable and discard the air tank

according to the your municipality by-laws.

1. Never drill into, weld, patch or modify the air tank. Immediately

replace the tank or compressor if an air leak develops. The leak

may lead to a rupture.

2. Never make adjustments to the components that control tank

pressure. Serious injury or death may occur if modifications are

made to the pressure switch, safety relief valve or other

components that control the tank pressure.

3. Check operation of the pressure relief valve on a regular basis and

never operate without a factory approved pressure relief valve. Do

not make alterations to the factory operating pressure settings.

VIBRATION PRECAUTIONS

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

vibration may cause temporary or permanent physical injury. Take

frequent breaks when using the tool.

2. 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.

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

1. Wrap the external threads of the male coupler with sealant tape.

1.1 Wrap tape in a clockwise direction so it will not unravel.

1.2 Do not tape all the threads. Leave several leading threads

unwrapped for easier alignment.

2. Screw the coupler into the tool's air inlet (D) and tighten with a

wrench until snug.

3. Run the compressor at a low volume and check the connection for

air leaks. Do not use the tool until all air leaks are repaired or the

faulty component is replaced.

IMPORTANT! Vibration may cause failure if a quick coupler is

connected directly to the air tool. To overcome this, connect a

leader hose to the tool. A quick coupler may then be used to

connect the leader hose to the air line hose.

INSTALL SPRING RETAINER

1. Align the rear of the spring retainer (A) with the threads on the

cylinder (B).

2. Thread the coil onto the cylinder. Twist the coil by the front loop. It

will spread the spring out slightly, making it easier to thread. Stop

when the rear loop is at the last thread on the left side of the air

hammer.

3. To remove the spring retainer, reverse the steps above, but use the

rear loop for leverage.

ACCESSORY INSTALLATION

1. Remove the internal packing grease from the tool before the first

use. See Air Tool Lubrication for instructions.

2. Disconnect the tool from its air source and discharge any residual air

before attaching or changing chisels or accessories.

3. Select your chisel (E to H). Make sure it is in good working

condition and will not shatter or break while in use.

4. Push the arm of the spring retainer to widen the opening so a

chisel shank can be inserted or removed. Once the chisel is

seated, release pressure on the spring retainer so it will close over

the raised ridge on the chisel shank and lock it into place. You may

need to rotate the chisel shank a bit for it to lock.

5. Pull on the chisel to confirm it is locked into place.

6. Test the chisel placement by running the tool at no load for

approximately 30 seconds. Point the chisel in a safe direction in

case it is ejected from the air hammer.

OPERATION

PRESSURE DROP

Apply the air consumption and pressure rate numbers to the tool’s air

inlet, not the compressor’s outlet. Calculate the pressure drop for your

air supply set-up and increase the compressor outlet pressure to

compensate. Make sure you do not exceed the maximum pressure for

any part of your air supply system.

Installing a pressure gauge at the tool inlet is the best way to measure

the air pressure and adjust the compressor’s output.

TOOL OPERATION

1. Ensure the regulator switch is in the neutral or OFF position.

2. Connect the tool to the air source.

3. Turn the compressor regulator to the desired air pressure (see

Specifications).

4. Firmly grip the air hammer with both hands and place the chisel

against the workpiece.

5. Squeeze the trigger (C) and slowly move along the workpiece. Do

not force the air hammer; let the tool do the work.

6. If the chisel is not performing well, turn off the tool and examine the

chisel to see if it is dull. Replace with a sharp chisel. Remember

that sharp tools are safer than ones that have become dull.

7. Once finished, disconnect the tool from its air source and

discharge any residual air in the tool before storing it.

8. Remove the chisel and the spring retainer after each use. Clean the

air hammer, retainer and chisels to make sure there is no

accumulated dust or debris remaining on the tool. Reinstall the

retainer back onto the air hammer before storage.

CARE & MAINTENANCE

1. Maintain the tool with care. A tool in good condition is efficient,

easier to control and will have fewer problems.

2. Inspect the tool fittings, alignment, hoses and power supply cord

periodically. Have damaged or worn components repaired or

replaced by an authorized technician. Only use identical

replacement parts when servicing.

3. Follow instructions for lubricating and changing accessories.

4. Only use accessories intended for use with this tool.

5. Keep the tool handles clean, dry and free from oil/grease at all times.

6. Maintain the tool’s labels and name plates. These carry important

information. If unreadable or missing, contact Princess Auto Ltd. for

replacements.

WARNING! Only qualified service personnel should repair the

tool. An improperly repaired tool may present a hazard to the

user and/or others.

AIR TOOL LUBRICATION

NOTICE! Only use air tool oil to lubricate the tool. Other lubricants

are not suitable and will damage the tool or cause a malfunction

during use.

NOTICE! Never use a penetrating oil to lubricate an air tool.

Penetrating oil acts as a solvent that will dissolve the tool’s

grease packing and may damage the o-rings, causing the tool to

seize or malfunction.

1. All air tools have an internal coating of grease to prevent corrosion

during shipping and storage. Remove this grease by adding a

generous amount of air tool oil in the air inlet and then run the tool

under no load until the exhaust is clear.

2. Manually add a drop or two of air tool oil into the tool’s male coupler

before each use and after every hour of continuous use. The tool will

not work properly without lubrication and parts will wear prematurely.

3. Avoid adding too much air tool oil as this can cause premature

power loss and eventual tool failure. A qualified technician will need

to take the tool apart and clean out the excess oil.

4. Apply a generous amount of air tool oil to the tool before storing it

for an extended period of time (overnight, weekend, etc.). Run the

tool for approximately 30 seconds to ensure the oil is evenly

distributed throughout the tool. Store it in a clean and dry location.
