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. 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.

BEFORE USE
FITTING A SANDING DISC
1. Select the disc to be used which
MUST be 150mm diameter with
hook and loop backing.
2. Line up the holes in the disc with
those on the sanding pad. (This is
necessary for dust extraction
purposes). Press the disc firmly onto
the pad to secure it.
CONNECTING THE AIR SUPPLY
Ensure the compressor is turned off and that the trigger is NOT depressed when
connecting the air line to avoid inadvertent starting of the sander.
1. Remove the protective plug from
the air inlet and connect a suitable
hose with a male end fitting or use
the adaptor supplied to connect a
suitable hose.
2. Connect 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 useful for sealing threaded connections.
4. If required, connect an in-line mini oiler to the tool. A mini oiler helps to
prolong the life of the air tool.
5. 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 or via the hose at the
nearest connection to the air supply.
6. A gauze filter is fitted within the air inlet. Ensure this filter is always kept
clean. An airline can be connected to the adapter, via a quick release
coupling (not supplied).
WARNING: COMPRESSED AIR CAN BE DANGEROUS. ENSURE THAT YOU
ARE FAMILIAR WITH ALL PRECAUTIONS RELATING TO THE USE OF AIR
COMPRESSORS AND A COMPRESSED AIR SUPPLY.

CONNECTING THE DUST COLLECTION TUBE & BAG
1. Push the dust collection tube onto
the waste outlet.
2. Use the string to tie the dust
collecting bag onto the smaller
end of the tube.
3. The dust bag should be emptied
regularly:- do not wait until it is
completely full. Gently pull open
the velcro flap across the end of
the bag to empty the contents
into your bin.
Your sander is now ready for use. Alternatively, vacuum extract can be used.
OPERATION
IMPORTANT: Only use abrasive sanding pads designed for use with this type
of 150mm dia sanding pad (rated at over 10000rpm).
1. Squeeze the trigger against the
body of the tool to start.
• Use the speed regulator to set
the speed.
• Move the regulator lever
forwards for maximum speed
and back to slow down.
2. Rest the sander on the workpiece
before starting it. Let the sander do
the work.
• The actual weight of the sander is normally sufficient for efficient
sanding. Do not put additional pressure on the sander which would
only slow down the speed of the pad, reducing efficiency and
placing an additional burden on the motor.
3. Pass the sander back and forth in wide, overlapping areas, taking care to
keep the sander moving around at all times. Avoid dwelling in one place
for more than a moment.
4. Release the trigger to stop the sander.
5. Always ensure the sander has stopped before putting it down.

DISCONNECTING THE AIR SUPPLY
1. Do not disconnect the air supply hose until the compressor has been shut
down and the compressed air released.
2. Squeeze the trigger to discharge any compressed air from the sander and
air hose.
3. Once the pressure has been released, disconnect the air supply hose from
the sander.
MAINTENANCE
Please note that factors other than the tools condition 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.
DAILY
1. Before use, drain water from the air-line and compressor.
2. Lubricate the air tool daily for optimum performance, using a high quality
airline oil either via a lubricator in the air supply system or by placing a few
drops into the air inlet immediately before use. This should be carried out
regardless of whether or not an in-line lubricator is used.
CLEANING
1. Keep the sander clean and free from debris.
2. Grit or gum deposits in the mechanism may eventually reduce efficiency.
This condition can be corrected by cleaning the air inlet filter and flushing
out the tool with gum solvent oil or an equal mixture of SAE No10 oil and
paraffin.
3. Failing this, the tool should be disassembled, thoroughly cleaned, dried
and reassembled. You may prefer to take the tool to your CLARKE dealer if
internal maintenance is required.
4. If the sander becomes sluggish 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.
WARNING: MAKE SURE THAT THE AIR TOOL IS DISCONNECTED FROM THE
AIR SUPPLY BEFORE STARTING ANY CLEANING OR MAINTENANCE
PROCEDURES.
