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 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.

• 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 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. 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 air inlet.
3. Connect a suitable hose to the female air inlet
4. Connect the other end of the hose to the air supply.
5. Turn on the air supply and check for air leaks.
• Rectify any found before proceeding.
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.).
OPERATION
Before starting work drain any water from the air tank and blow condensation
from the air line. Drain compressor more frequently in hot humid weather.
Note: item Nos refer to parts list, Page 10.
Ensure the correct nosepiece (item 1x) is installed for the size of the rivet
mandril being used, insert the mandril until the rivet buts snugly against the
nosepiece.
WARNING: COMPRESSED AIR CAN BE DANGEROUS. ENSURE THAT YOU
ARE FAMILIAR WITH ALL PRECAUTIONS RELATING TO THE USE OF AIR
COMPRESSORS AND COMPRESSED AIR SUPPLY.

Insert the rivet into the workpiece to be secured, pressing firmly depress the
trigger. The riveter will ‘fire’, breaking off the mandril, allowing the riveter to be
removed from the workpiece and re-loaded. Spent mandrills will be ejected
from the rear of the riveter.
To change the nosepiece, unscrew and remove the installed nosepiece, a
slight spring resistance will be felt.
Choose the nosepiece to be installed, push firmly against spring resistance into
the head (item 2), screw home and tighten with the wrench supplied.
DISCONNECTING THE AIR SUPPLY
Do not disconnect the air supply hose until the air supply has been shut down
and the compressed air 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.
Store the tool safely in its box in a dry, secure environment.
MAINTENANCE
DAILY
1. Before use, drain water from the compressed air supply.
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.
CLEANING
1. Keep the body of the tool clean and free from debris. Grit or gum deposits
in the tool may reduce efficiency.
If the riveting action becomes erratic or the riveter operates but fails to form a
rivet successfully, it is possible that the jaw housing assembly (items 3 - 8)has
worked itself loose, and requires adjusting. Should this occur, proceed as
follows:
WARNING: MAKE SURE THAT THE TOOL IS DISCONNECTED FROM THE AIR
SUPPLY BEFORE STARTING ANY CLEANING, OR MAINTENANCE
PROCEDURES.

Parts & Service: 020 8988 7400 / E-mail: [e-mail] or [e-mail]
1. Unscrew and remove the head assy (item 2).
2. Using the wrench supplied, hold the jaw housing coupler (item 7), undo the
locknut (item 8).
3. Place the 56mm gauge (on the edge of the wrench provided), alongside
the jaw housing assembly (item 35 inset), and screw the jaw assy in or out,
so that the lip of the gauge is in line with the end face of the jaw housing
(item 3.) Secure in position with the locknut (item 8).
Additionally, following prolonged use, the jaws may fail to grip the mandril
effectively, and will therefore need replacing. Dis-assemble the jaw housing
assembly, and re-assemble using genuine parts supplied from your nearest
CLARKE dealer, ensure you carry out the adjustment above.
SERVICE AND REPAIR
If the tool runs erratically or becomes inefficient although the air supply is in
good order, it may be necessary to dismantle the tool. Such servicing and
repair work should be carried out by qualified service technicians.
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.
Grit or gum deposits inside the tool may also reduce its efficiency. This
condition can be corrected by cleaning out the air strainer and flushing out
the tool with gum solvent or oil, or failing this, the motor may require
dismantling.
**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 for 5 seconds in order to
lubricate the internal parts.
When not in use, disconnect from air supply, clean tool and store in a safe, dry
place.
ACCESSORIES
A wide range of accessories is available including filter/regulators, lubricators,
high-pressure hoses (5 to 50 metres) etc.
