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. 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.
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
NOTE: Ensure the compressor 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.
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 inlet connector or via the hose
at the nearest connection to the air supply.
3. Connect a suitable hose as shown.
4. Connect the other end of the hose
to the compressor.
5. Turn on the air supply and check
for air leaks. Rectify any found
before proceeding.
• PTFE tape may be helpful for
sealing threaded connections.
6. 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. Three 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 a different 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.
WARNING: COMPRESSED AIR CAN BE DANGEROUS. ENSURE THAT YOU
ARE FAMILIAR WITH ALL PRECAUTIONS RELATING TO THE USE OF AIR

into the collet and tighten the
screw cap finger tight.

seat to stop the tool from rotating.
3. Use the other wrench to fully
tighten the collet and grip the
stone in position as shown.
OPERATING THE DIE GRINDER
1. Use your thumb to slide the
throttle locking lever forward while
squeezing the trigger against the
body of the tool.
2. Do not use excess pressure on the
grinding stone as this will shorten
its life.
3. Release the trigger to stop the
grinder.
• The tool will continue to rotate
very briefly after the trigger has been released.
Always ensure the grinder has stopped before putting it down.
SETTING THE SPEED

the air regulator on top of the tool
body using a suitable screwdriver.
DISCONNECTING THE AIR SUPPLY
