SAFETY PRECAUTIONS
IMPORTANT
Failure to follow these precautions could
result in personal injury, and/or damage to
property.
❐ When operating this tool, ALWAYS wear:
a. approved impact resistant SAFETY
GOGGLES. (Eye glasses are NOT
safety glasses)
b. a DUST MASK
c. EAR DEFENDERS
d. a good pair of INDUSTRIAL GLOVES
❐ ALWAYS disconnect the tool when not
in use, and before carrying out any
maintenance
❐ ALWAYS keep a safe distance between
yourself and other people when using
the tool.
❐ ALWAYS maintain the tool with care. Keep
it clean for best and safest performance.
❐ NEVER wear ill fitting clothing, remove
watches and rings.
❐ Quick change couplings should not be
located at the tool. They add weight
and could fail due to vibration.
❐ DO NOT overreach. Keep your proper
footing and balance at all times.
❐ DO NOT force or misuse the tool. It will
do a better and safer job at the rate for
which it was designed.
❐ DO NOT abuse hoses or connectors.
NEVER carry a tool by the hose, or yank
it to disconnect from the air supply. Keep
hoses away from heat, oil and sharp
edges. Check hoses for leaks or worn
condition before use, and ensure that
all connections are secure.
❐ DO NOT exceed 90 PSI at the tool.
❐ DO NOT modify the tool in any way.
❐ DO NOT remove any labels. Damaged
labels should be replaced.
❐ This tool vibrates with use. Vibration may
be harmful to your hands or arms. Stop
using the tool if discomfort, a tingling
feeling or pain occurs. Seek medical
advice before resuming use.
❐ ALWAYS use screens to protect people
in the vicinity from flying debris.
❐ NEVER point the tool at anyone.
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
(6.2bar), 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. 1 on
inside front cover.
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 6mm (¼") ID., and fittings
should have the same inside dimensions.
ASSEMBLY
Connect a suitable hose to the Drill 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. NOTE: ensure the airline is turned off.
Your Drill is now ready for use.
WARNING
Compressed air can be dan-
gerous. Ensure that you are
thoroughly familiar with all
precautions relating to the use
of compressors and com-
pressed air supply.
OPERATING INSTRUCTIONS
Before starting work drain any water from the
air tank and blow condensation from the air
line. Drain compressor more frequently in hot
humid weather.
1. Disconnect tool from airline
2. Ensure that drill bit (Item 44) is properly
located in drill and grub screw (Item 33) is
fully tightened against flat portion on drill
bit. Slacken depth stop nut (Item 42) and
screw depth stop (Item 41) away from the
drill bit. Depress grip handle fully and then
adjust depth stop to required depth of cut
(see figure 2), Inside front cover.
3. Connect air line to tool, turn air on, check
for air leaks. If any are apparent,
rectify before proceeding.
4. position drill over spot weld (a centre
punch mark in the centre of spot weld may
aid accuracy).
5. Depress grip handle, which will start the
tool, apply a steady, even pressure. Do
not force. Too much pressure can cause
drill to break or overheat. too little pressure
will keep drill from cutting and cause it to
overheat.
6. When grip handle is fully depressed, drilling
is complete.
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 disassembled,
thoroughly cleaned, dried and reassembled.
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:
The use of parts other than CLARKE replacement parts may result in safety hazards, decreased tool performance and
may invalidate your warranty.
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 drill 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.
