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

COMPRESSED AIR REQUIREMENTS

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

• Air compressors used with the impact wrench 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 impact wrench. 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 and topped up with oil. SAE 10 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 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.

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.

2. Connect a suitable hose to the tool and the other end of the hose to the

compressed air supply.

3. Turn on the air supply and check for air leaks. Rectify any found before

proceeding.

• PTFE tape may be helpful for sealing threaded connections.

• 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 it

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.

5. Chisel force may be adjusted by turning the regulator knob, located at the

base of the handle grip. Turn anti-clockwise (unscrew) to increase force,

clockwise (screw in) to reduce.

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

• 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. Refer to the compressor instruction

manual for the procedure to shut down and release the compressed air. Once

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

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 for 5 seconds in order to

lubricate the internal parts. Clarke air-line oil is available from your Clarke

dealer, part no. 3050825.

TROUBLESHOOTING

SYMPTOM PROBLEM SOLUTION

Tool runs slowly or will

not operate.

Dirt or gum in the tool Flush the tool with air line oil

or gum solvent.

Air hose leaks. Tighten and seal hose

fittings with teflon tape.

Low air pressure. Adjust compressor

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

of water. Oil tool again.

Tool will not shut off. O-rings damaged or ill-

fitting in seat.

Return to Clarke dealer for

repair.

Tool runs erratically. Cylinder may have

come loose from the

housing.

Tighten cylinder or return to

Clarke dealer.

MAINTENANCE

DAILY

1. Before use, drain water from the air tank, air line and compressor.

2. Pour a few drops of CLARKE airline oil, into the air inlet. This should be

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

inline mini oiler is not used, this procedure should be repeated after every

two to three hours of use.

3. Check the air inlet screen filter for blockage and clean if necessary.

CLEANING

1. Keep the body of the tool clean and free from debris.

2. Grit or gum deposits in the tool may also reduce efficiency. This condition

can be corrected by cleaning the air strainer and flushing out the tool with

gum solvent oil, or failing this, the tool should be disassembled, thoroughly

cleaned, dried and reassembled.

3. After extensive use, remove the inlet screen filter and flush out the

mechanism with gum solvent oil or an equal mixture of SAE No10 oil and

paraffin. Allow to dry before use.

4. If the tool runs erratically or becomes inefficient, and the air supply is of

good quality, it may be necessary to dismantle the air motor and 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.

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

SUPPLY BEFORE STARTING ANY CLEANING, OR MAINTENANCE

PROCEDURES.
