AIR SUPPLY REQUIREMENTS
WARNING: COMPRESSED AIR CAN BE DANGEROUS. ENSURE THAT YOU
ARE THOROUGHLY FAMILIAR WITH ALL PRECAUTIONS RELATING TO THE
USE OF COMPRESSORS AND COMPRESSED AIR SUPPLY.
• 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 in the air compressor will accelerate wear and
corrosion in the moving parts. 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), line presure may
need to be increased.
• Never exceed the maximum operating pressure for the tool.
• The air hose must be rated at least 150% of the maximum operating
pressure of the tool.
• A pressure of 90psi with a flow of 6 cfm is required. Too high an air pressure
will shorten the life of the tool due to excessive wear.
A typical airline layout is shown. If an automatic in-line filter/regulator/
lubricator unit is used it will keep the tool in good condition, but should be
regularly checked and topped up with oil.
IMPORTANT: If a filter/lubricator unit is not used, the air tool should be
lubricated with 2 to 6 drops of oil, at least once a day or after 2 hours work,
depending upon the working environment. The oil can be inserted through
the airline connection fitting.

BEFORE USE
INSTALLING THE DISC
1. To assemble the pad to the tool,
turn the locking nut (A) until the
knurled portion contacts the flat
surface on the output spindle (B).
2. Thread the pad into the spindle
by gripping theorbital hub (C)
with one hand and the pad with
the other.
3. Turn the locking nut until the
spindle turns freely. Do Not
operate the tool with the spindle
in the locked mode as performance would be severly affected and a
hazardous situation could result.
CONNECTING THE AIR SUPPLY
WARNING: COMPRESSED AIR CAN BE DANGEROUS. ENSURE THAT YOU
ARE FAMILIAR WITH ALL PRECAUTIONS RELATING TO THE USE OF
COMPRESSORS AND COMPRESSED AIR SUPPLIES.
Note: Ensure the compressor is turned off.
1. Remove the plastic blanking plug
from the connection port of the
tool as shown.
2. Pour 2-3 drops of CLARKE airline
oil into the air inlet. This should be
done regardless of whether or not
a lubricated air supply is to be
used.
3. Connect a suitable hose to the
tool as shown.
4. Connect the other end of the
hose to the compressor. (A whip hose with a quick fit coupling is available
from your CLARKE dealer).
5. Turn on the air supply and check for air leaks. Rectify any found before
proceding. The tool is now ready for use.

OPERATION
IMPORTANT: Only use abrasive sanding pads designed for use with this type of
150mm dia sanding pad.
1. Squeeze the trigger against the
body of the tool to start and
evaluate its speed.
The regulator valve can be used
for setting positive speed control.
2. Rest the sander on the workpiece
and start the machine. Let the
sander do the work.
• The actual weight of the machine
is normally sufficient for efficient
sanding. Do not put additional pressure on the machine, which would only
slow down the speed of the pad, reducing efficiency and placing an
additional burden on the motor.
4. 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.
5. Release the trigger to stop the tool.
6. Always ensure the tool 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 pressure released.
2. Once the pressure has been released, disconnect the air supply hose from
the tool.
STORAGE
1. Store the tool safely in its box in a dry, secure environment.
2. If the tool is not to be used for longer than 24 hours, run a few drops of
CLARKE airline oil into the air inlet and run the tool for a few seconds to
ensure that the oil has been well distributed throughout the tool.
3. When storing, ensure the blanking plug is replaced on the airline
connector once the airline has been disconnected.
