AIR HAMMER SPECIFIC HAZARDS

1. Only use accessories designed for use with this power tool.

2. Never use any of the chisels supplied as hand struck tool.

3. Never use blunt chisels which require excessive pressure and can break

from fatigue. Always use sharp tools.

4. Never mis-use the tool by prising which can result in a broken tool.

5. Ensure there are no hidden electrical cables, gas pipes etc, which could

cause a hazard if damaged by action of the chisels.

IMPORTANT

Please read all of the safety and operating instructions carefully before using

this product. The following safety symbols are to be found on the machine.

Keep these instructions in a safe place for future reference.

Read this instruction

booklet carefully

before use.

Wear ear protection

Wear eye protection Wear dust mask.

COMPRESSED AIR REQUIREMENTS

• Use only clean, dry, regulated compressed air as a power source.

• Air compressors used with the tool must comply with the appropriate

European Community Safety Directives.

• A build-up of moisture or oil in the air compressor will accelerate

wear and corrosion in the tool. ensure any moisture is drained from

the compressor daily and the inlet filter is kept clean.

• If an unusually long air hose is required, (over 8 metres), the line

pressure or the hose inside diameter may need to be increased.

• The air hose must be rated at least 150% of the maximum operating

pressure of the tool.

• A typical air line layout is shown above. If an automatic in-line filter/

regulator is used, it will keep the tool in good condition, but should

be regularly checked & topped up with oil. Clarke air-line oil should

be used, and the lubricator adjusted to approx 2 drops per minute.

• Never exceed the maximum operating pressure for the tool. It is

recommended that air pressure to this tool does not exceed 90 psi

at the tool when running. Higher pressures and unclean air will

shorten the life of the tool due to faster wear and is a possible safety

hazard.

WARNING: COMPRESSED AIR CAN BE DANGEROUS. ENSURE THAT YOU

ARE FAMILIAR WITH ALL PRECAUTIONS RELATING TO THE USE OF

COMPRESSORS AND A COMPRESSED AIR SUPPLY.

OVERVIEW

OPERATION

NOTE: Ensure the compressed air supply is turned off.

1. If required, connect an in-line mini oiler to the tool.

• A mini oiler helps to prolong the life of the air tool. Read the

instructions supplied with the mini-oiler before use.

NOTE: If a mini-oiler is not being used, insert a few drops of oil into the tool

through the air inlet before use.

2. Connect a suitable hose as shown.

3. Connect the other end of the hose

to the compressed air supply.

4. Turn on the air supply and check

for air leaks. Rectify any found

before proceeding.

• PTFE tape may be helpful for

sealing threaded connections.

5. Your air tool is now ready for use.

FITTING THE CHISEL

1. First remove the retaining spring

from the nose by unscrewing it.

• Use the inboard lug to gain

purchase.

2. Insert the chisel into the air

hammer as shown.

3. Replace the retaining spring as

shown.

• Use the lugs to tighten.

USING THE AIR HAMMER

1. Hold the tool firmly, then bring the

tool towards the work at an angle

of approximately 60-70 degrees.

2. Pull the trigger with the chisel in

light contact with the work.

3. Move slowly across the work

surface. To remove scale, rust or

other contaminants, only a light

force should be required.

4. Release the trigger to stop operation, whilst maintaining contact with the

work.

NOTE: that the tool may impact briefly after the trigger is released.

NOTE: The retaining spring has a life expectancy, depending upon the

intensity of usage. It is recommended that you procure a spare

spring for use in the event of failure occurring during the course of

a particular job.

DISCONNECTING THE AIR SUPPLY

Do not disconnect the air supply hose until the air supply has been shut down

and the compressed air pressure released.

1. Refer to the compressor instruction manual for the procedure to shut down

and release the compressed air.

2. Once the pressure has been released, disconnect the air supply hose from

the air tool.

3. Store the tool safely in its box in a dry, secure environment.

TROUBLESHOOTING

ACCESSORIES

A wide range of airline accessories is available including filter/regulators,

lubricators, high-pressure hoses (5 to 50 metres) etc.

regulator to 90 psi. Check

the hose is the correct size

and length.

No oil in tool Lubricate the tool.

Worn rotor blades. Return to Clarke dealer for

repair.

Water in airline. Drain air receiver and/or in-

line filter. Run tool until clear

MAINTENANCE

DAILY

1. Before use, drain any water from the compressed air supply.

2. This air tool should be lubricated before use. Turn the tool upside down and

pour 1-2 drops of Clarke air-line oil into the air inlet. This should be carried

out regardless of whether or not an in-line mini oiler is used. If an in-line mini

oiler is not used, this procedure should be repeated after every two to

three hours of constant use.

CLEANING

1. Keep all parts of the tool clean.

2. Deposits in the tool may also reduce efficiency. This can be corrected by

cleaning the air inlet and flushing out the tool with gum solvent, or failing

this, the tool should be disassembled, thoroughly cleaned, dried and

reassembled.

3. If the tool becomes inefficient and the air supply is of good quality, it may

be necessary to replace worn or damaged parts. You may prefer to take

the tool to your Clarke dealer if internal maintenance is required.

Your Clarke air tool has been designed to give long and trouble free service. If,

however, having followed the instructions in this booklet carefully, you

encounter problems, take the unit to your local Clarke dealer.

PERFORMANCE

Please note that factors other than the tool may effect its operation and

efficiency such as reduced compressor output, excessive drain on the airline,

moisture or restrictions in the air-line, or the use of connectors of improper size

or poor condition which will reduce air supply.

**Clarke Air-line Oil (part no. 3050825) is available from your Clarke dealer.

STORAGE

If the tool is to be stored, or is idle for longer than 24 hours, run a few drops of

Clarke air-line oil into the air inlet and run the tool in order to lubricate the

internal parts. When not in use, disconnect the tool from the air supply, clean

and store in a safe, dry place.

WARNING: MAKE SURE THAT THE AIR TOOL IS DISCONNECTED FROM THE

AIR SUPPLY BEFORE STARTING ANY CLEANING, OR MAINTENANCE

PROCEDURES.
