MAINTENANCE
Daily before use.
1.
Drain water from air tank, air line and
compressor.
2.
Check and clean, if necessary, the air
inlet gauze filter .
3.
Pour a few drops of CLARKE Air Line Oil
(approx 3cc), into the air inlet. This should
be carried out regardless of whether or
not an air line lubricator is used.
If an Air line lubricator is NOT used, this
procedure should be repeated after
every two to three hours of use.
If the Grinder 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.
For lubricating the air motor when in
operation, an air line lubricator should be
used, with Clarke Air Line Oil, adjusted to 2
drops per minute.
Clarke Air Line Oil is available from your
CLARKE dealer, part no. 3050825.
Be aware that factors other than the tool
may effect its operation and efficiency, such
as reduced compressor output, excessive
drain on the airline, moisture or restrictions in
the line, or the use of connectors of improper
size or poor condition which will reduce air
supply.
Grit or gum deposits in the tool may also
reduce efficiency. This condition can be
corrected by cleaning the air strainer and
flushing out the tool with gum solvent oil,or
failing this, the tool should be dis-assembled,
thoroughly cleaned, dried and re-
assembled.
If the tool runs erratically or becomes
inefficient, and the air supply is sound,
dismantle the air motor and replace worn
or damaged parts, or take the tool to your
CLARKE dealer.
IMPORTANT:
T
he use of parts other than CLARKE
replacement parts may result in safety
hazards, decreased tool performance
and may invalidate your warranty.
AIR SUPPLY
Tools of this type, operate on a wide range
of air pressures. It is recommended that air
pressure to this tool does not exceed 90 PSI,
at the tool when running. Higher pressure
and unclean air, will shorten the tools’ life
because of faster wear, and could be a
safety hazard.
Water in the air line will cause damage to
the tool, ensure it is properly maintained at
all times.
The recommended procedure to connect
this tool to an air supply, is shown at fig. 2 on
page 5.
The air inlet used for connecting air supply,
has a standard ¼” BSP thread.
Line pressure, or hose inside diameter, should be
increased to compensate for unusually long air
hoses (over 10m). Minimum hose diameter
should be 8mm (5/16") ID., and fittings should
have the same inside dimensions.
ASSEMBLY
With the air supply turned OFF, connect the
hose of the Grinder to your airline and then
insert the spindle of the tool to be used into
the collet of the drive spindle, tightening the
collet nut using the two spanners provided.
Your Grinder is now ready for use.
OPERATION
Turn ON the air supply, and check for air
leaks. If any are apparent, rectify before
proceeding.
Hold the tool so that the operating lever is
in the palm of one hand. With the airline
pressure set to 90 lbf/in
2
(6.1bar), push the
spring loaded safety latch, mounted in the
operating lever, forward. This allows the
operating lever to be depressed, starting
the tool .
To stop the tool, release the trigger. The
safety latch will automatically lock the
operating lever preventing further operation
intil it is again pushed forward.
NOTE: The speed of the tool is factory set to
25,000RPM, and should not need adjusting.
