THE COMPRESSED AIR SUPPLY

AIR SUPPLY 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 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.

• The minimum hose diameter should be 5/16”(8mm) ID and fittings

should have the same internal dimensions.

WARNING: COMPRESSED AIR CAN BE DANGEROUS. ENSURE THAT YOU

ARE FAMILIAR WITH ALL PRECAUTIONS RELATING TO THE USE OF

COMPRESSORS AND COMPRESSED AIR SUPPLY.

Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Service@clarkeinternational.com

• 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.

BEFORE USE

NOTE: Ensure the compressor 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. Remove the

oil fill screw from the side of the

mini oiler and fill with Air-line Oil

available from your CLARKE

dealer. Replace the screw

before using the tool.

2. If a mini-oiler is not being used, run

a few drops of oil through the tool before use. It can be entered through

the inlet strainer or via the hose at the nearest connection to the air supply.

3. Connect a suitable hose as shown.

4. Connect the other end of the hose to the compressor.

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

proceeding

6. Your air tool is now ready for use.

You can fit a whip hose with a quick fit coupling if required (available from

your Clarke dealer.)

MAINTENANCE

DAILY

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

• 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.

WEEKLY

• 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. Clean the air inlet filter screen inside the hose adaptor.

5. 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.

WARNING: MAKE SURE THAT THE IMPACT WRENCH IS DISCONNECTED

FROM THE AIR SUPPLY BEFORE STARTING ANY CLEANING, OR

MAINTENANCE PROCEDURES.
