resulting from sanding and used dust extraction systems where possible.
5. Always wear a face mask when using the sander as protection from
airbourne particles of sanded material. Avoid disturbing existing dust and
minimise the scattering of dust in the worplace environment. Take steps to
control the dust at the point of emission.

COMPRESSED AIR REQUIREMENTS
• Use only clean, dry, regulated compressed air as a power source.
• Air compressors used to drive this 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 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 does not exceed 90 psi when
running. Higher pressures and contaminated 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 AIR
COMPRESSORS AND COMPRESSED AIR SUPPLIES.

BEFORE USE
CONNECTING AIR HOSES
NOTE: Ensure the compressor is turned off while connecting hoses.
1. If required, connect an in-line lubricator to the tool.
• A lubricator helps to prolong the life of the air tool.
2. If a lubricator 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.
3. Connect a suitable hose to the air
inlet as shown.
4. Connect the other end of the hose
to the compressor.
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).
INSTALLING THE COLLET
1. Select the grinding stone you require.
2. Two collets of different sizes are
provided. Select whichever fits
the shank of the stone you have
chosen.
• One collet may already be
installed in the grinder.
3. If the other collet is to be used,
undo the retaining collar
completely and pull out the collet
from the collet seat. Replace it
with the new collet and screw the collar loosely back on.
WARNING: COMPRESSED AIR CAN BE DANGEROUS. ENSURE THAT YOU
ARE FAMILIAR WITH ALL PRECAUTIONS RELATING TO THE USE OF AIR
COMPRESSORS AND COMPRESSED AIR SUPPLIES.

FITTING THE GRINDING STONE
IMPORTANT: Never use chipped or cracked grindstones.
1. Slip the shank of the chosen stone
into the collet and tighten the
retaining collar finger tight.
2. Place the smaller of the two
wrenches over the collet seat to
stop the tool from rotating.
3. Use the larger wrench to fully
tighten the collet and grip the
stone in position as shown.
FITTING THE SANDING DISC
1. Fit the larger collet to the tool and
slip the spindle into the collet.
Secure in place by tightening the
collar as above.
2. Screw the sanding arbor onto the
spindle and secure by tightening
the nut against it using the larger
wrench.
3. Screw the sanding pad onto the
sanding arbor.
OPERATING THE TOOL
1. Use your thumb to slide the
throttle locking lever forward while
squeezing the trigger against the
body of the tool.
2. Adjust the tool speed by varying
the pressure on the trigger.
3. Do not use excess pressure on the
grinding stone as this will shorten
its life.
4. Release the trigger to stop the
tool.
• The tool will continue to rotate for a short time after the trigger has
been released.
5. Always ensure the tool has stopped before putting it down.

SANDING AND GRINDING TIPS
• Do not force the disc or stone against the material.
• The key to efficient grinding is to control the pressure and surface
contact between the grinding tool and the workpiece.
• Allow the tool to reach full speed before grinding.
• Avoid overloading the grinder. If it becomes hot during use, rest for a
few minutes while it cools down.
TROUBLESHOOTING
SYMPTOM PROBLEM SOLUTION
Tool runs at normal
speed but slows down
under any load.
1. Excessive pressure on
tool.
2. Motor parts worn.
3. Worn or sticking
mechanism due to
lack of lubricant.
1. Reduce the force
applied to the tool.
2. Return to Clarke dealer
for repair.
3. Drip air tool lubricating
oil into the air inlet. Allow
oil to soak the moving
parts before using.
Tool runs slowly. Air
flows weakly from
exhaust.
1. Motor parts jammed
with gum/dirt.
2. Regulator in closed
position.
3. General airflow
blocked by dirt.
1. Examine inlet air filter for
cleanliness.
2. Adjust the regulator to the
open position.
3. Operate the tool in short
bursts.
Tool will not run. Air
flows freely from
exhaust.
1. Motor vanes stuck
due to buildup of
foreign material.
1. Disconnect air supply
and rotate tool assembly
manually.
2. Try operating tool in
short bursts.
3. Drip a few drops of air
tool lubricating oil into
the air inlet to soak moving
parts.
Tool will not shut off. 1. Throttle O-rings
damaged or ill-fitting
in seat.
1. Return to Clarke dealer
for repair.

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. Refer to the compressor instruction manual for the procedure to shut down
and release the compressed air.
3. Once the pressure has been released, disconnect the air supply hose from
the air tool.
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 in-line
lubricator is not used, this procedure should be repeated after every two to
three hours of use.
WEEKLY
1. Check the air inlet strainer for
blockage and clean if necessary.
CLEANING
1. Keep the body of each tool clean
and free from debris.
2. 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. This is better left to your Clarke dealer.
WARNING: MAKE SURE THAT THE AIR TOOL IS DISCONNECTED FROM THE
AIR SUPPLY BEFORE STARTING ANY CLEANING OR MAINTENANCE
PROCEDURES.

GREASING
The right angle drive is fitted with a
grease nipple to provide a facility for
lubrication of the drive gears.
1. After extensive use, apply a shot
of general purpose grease using a
suitable grease gun.
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 air motor and replace any
worn or damaged parts. Such servicing and repair work should be carried out
by a qualified service technician.
PERFORMANCE
Please note that factors outside the tool may effect its operation and
efficiency such as reduced compressor output, excessive air demand from
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.
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 tools and store in the
moulded case provided. When storing, ensure the blanking plug is replaced
on the airline connector once the airline is disconnected.
ACCESSORIES
A wide range of accessories is available including filter/regulators, lubricators,
high-pressure hoses (5 to 50 metres) etc. Contact your CLARKE dealer for
further information or CLARKE International Service Department.
