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 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 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 COMPRESSED AIR SUPPLY.

BEFORE USE
NOTE: Ensure the compressor is turned off.
1. Remove the blanking plug from the inlet connection of the tool.
2. If required, connect an in-line mini oiler to the tool.
• A mini oiler helps to prolong the life of the air tool.
3. 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.
4. Connect a suitable hose to the air
inlet as shown.
5. 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).
FITTING THE CUTTING DISC TO THE CUT-OFF TOOL
1. Ensure the disc being fitted has a speed rating greater than 20,000 rpm
which is the maximum speed of the tool.
2. Install the disc and retaining
washer using the spanner and hex
key supplied.
NOTE: When fitting the cutting disc,
always ensure that the side
of the disc with the metal
centre faces away from the
tool, so as to touch the
retaining washer.

IMPORTANT: Use the correct disc. Using an incorrect disc can cause serious
injury.The use of parts other than CLARKE replacement parts may result in
safety hazards, decreased tool performance and may invalidate your
warranty.
Replacement cutting discs are available from your Clarke dealer. (Part
number 3110731).
INSTALLING THE COLLET TO THE DIE GRINDER
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 seat. Replace it with the
new collet and screw the cap loosely back on.
FITTING THE GRINDING STONE INTO THE DIE GRINDER
IMPORTANT: Never use chipped or cracked grindstones. Never use
grindstones not rated to operate at a speed equal to, or greater than, the
full operating speed of the air tool.
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 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.
