COMPRESSED AIR REQUIREMENTS
A typical air line layout is shown below. 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.
.
Use only clean, dry, regulated compressed air as a power source.
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: [e-mail] or [e-mail]
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 air tool.
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. Remove the plastic blanking plug from the air inlet connection.
2. Pour 2-3 drops of airline oil into the oil filling port. This should be done
regardless of whether or not a lubricated air supply is to be used.
3. If required, connect an in-line mini oiler to the tool.
• A mini oiler helps to prolong the life of any air tool.
4. Connect a suitable hose as shown
or use the snap connector
supplied to connect directly to the
hose.
5. Connect the other end of the hose
to the compressor.
• PTFE tape may be useful for
sealing threaded connections.
6. Turn on the air supply and check
for air leaks. Rectify any found
before proceeding.
7. If using a mini oiler, place a sheet of paper next the exhaust port and hold
the throttle open for approximately 30 seconds. The oil volume is correctly

ARE FAMILIAR WITH ALL PRECAUTIONS RELATING TO THE USE OF AIR
COMPRESSORS AND COMPRESSED AIR SUPPLY.

set when a light stain of oil can be seen on the paper. Excessive oil should
be avoided.
Your die grinder is now ready for use.
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.
• The larger collet is probably
already installed in the grinder.
3. If the other collet is to be used,
undo the screw cap completely
and pull out the collet from the
collet holder. Replace it with the
new collet and screw the cap loosely back on.
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
screw cap finger tight.
2. Place the smaller of the two
wrenches (11mm) over the collet
seat to stop the tool from rotating.
3. Use the larger wrench (17mm) to
fully tighten the collet and grip the
stone in position as shown.
4. If another collet is to be used,
undo the screw cap completely and pull out the collet from the collet seat.
Replace it with the new collet and screw the cap loosely back on.

ADJUSTING THE SPEED
1. Set the tool speed by rotating the
control to one of the four settings.
• The numbers on the speed
control knob indicate the
speed setting when aligned
with the reference mark on the
air inlet.
• Speeds available are: 8300,
13000, 22000 or 25000 rpm (+/-
10%).
OPERATING THE DIE GRINDER
1. Slide the throttle locking lever
forward while squeezing the
trigger against the tool body.
2. Do not use pressure on the stone
as this will shorten its life.
3. Release the trigger to stop the
grinder.
• The tool will continue to rotate
for a short time after the trigger
has been released.
4. Always ensure the grinder has stopped before putting it down.
DISCONNECTING THE AIR SUPPLY
1. Do not disconnect the air hose until the supply is isolated at a shut-off
valve.
2. Once the pressure has been isolated, disconnect the air supply hose from
the air tool.
3. Shut down the compressor at the end of the work session.

TROUBLESHOOTING
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. When storing, replace the blanking plug to the air inlet once the airline
is disconnected.
Avoid storing the tool where the temperature is below 0oC.
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 air inlet. Allow oil
to soak 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 and clean if
necessary.
2. Adjust regulator to open
position.
3. Operate 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 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.
