SAFETY PRECAUTIONS

AIR SUPPLY
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.
The recommended
procedure to connect this
tool to an air supply, is
shown on the right.
We recommend that an
automatic in-line filter-
regulator-lubricator is used.
• It will keep the tool in
good condition. The in-line
lubricator should be regularly
checked and filled with air tool oil adjusted to 2 drops per minute.
AIR SUPPLY SAFETY
1. Ensure the trigger is in the OFF position before connecting to the air supply.
2. You will require an air pressure of 90 psi, with an air flow of at least 4 CFM.
WARNING! ENSURE THE AIR SUPPLY IS CLEAN AND DOES NOT EXCEED
90PSI WHILE OPERATING THE TOOL. TOO HIGH AN AIR PRESSURE AND
UNCLEAN AIR WILL SHORTEN THE PRODUCT LIFE DUE TO EXCESSIVE
WEAR, AND MAY BE DANGEROUS CAUSING DAMAGE AND/OR
PERSONAL INJURY.
3. Drain the compressor daily. Water in the air line could damage the cut off
tool.
4. Clean air inlet filter weekly.
5. Line pressure should be increased to compensate for unusually long air
hoses (over 8 metres). The hose diameter should be 3/8" Internal Diameter.
The pressure at the cut off tool should not be over 90 psi.
AIR HOSE
• The air hose must be rated at least 150% of the maximum operating
pressure of the tool.

6
BEFORE USE
If an automatic in-line filter-regulator-lubricator is not used, the following
procedure should be carried out before use and after every two to three
hours of use.
1. Drain water from air tank, air line
and compressor.
2. Remove the plug from the rear
of the cut off tool.
3. Check and clean the air inlet
gauze filter.
4. Pour 2-3 drops of Clarke air line
oil (approx. 3 cc), into the air
inlet. This should be carried out
regardless of whether or not an air line lubricator is used.
5. Connect tool to air supply, turn ON the air supply, and check for air leaks.
If any are apparent, rectify before proceeding.
ASSEMBLY
NOTE : Ensure the airline is turned off.
1. Screw in the adaptor supplied.
2. Connect a suitable air hose to
the cut -off tool using a ¼” hose
adapter, (A whip hose with
quick fit coupling is available
from your CLARKE dealer). Then
connect the other end to the
airline.
Your cut-off tool is now ready for use.
•NEVER use cracked or chipped cutting discs.
•NEVER use non-reinforced cutting discs.
•NEVER use the cut off tool without disc guard in place.
•NEVER use the side of the cutting disc for grinding.

OPERATING INSTRUCTIONS
WARNING: ENSURE YOU READ, UNDERSTAND AND APPLY SAFETY
INSTRUCTIONS BEFORE USE.
1. Push safety lever (mounted on
the throttle lever) forward and
depress throttle lever.
•Allow tool to run up to full
speed for a couple of
seconds before offering disc
to work piece.
2. Apply a steady, even pressure.
Do not force. Too much pressure
can cause disc to break and
may even cause injury.
NOTE: DO NOT allow tool to free run for an extended period of time as
this will shorten its life.
CHANGING THE CUTTING DISC
WARNING: ENSURE AIR IS TURNED OFF AND TOOL IS DISCONNECTED
FROM THE AIR SUPPLY BEFORE REPLACING DISC.
1. Ensure the disc being fitted has a speed rating greater than 18,000 RPM.
2. Install disc using spanner and
hex key supplied. Ensure that the
spacer is in place.
IMPORTANT: The use of parts other
than CLARKE replacement parts
may result in safety hazards,
decreased tool performance and
may invalidate your warranty.

AUTHORISED PARTS MAY BE DANGEROUS
1. Lubricate the air tool daily by placing a few drops of air tool oil into the air
inlet.
TROUBLESHOOTING.
