THE COMPRESSED AIR SUPPLY
AIR SUPPLY REQUIREMENTS
• Use only clean, dry, regulated compressed air as a power source.
• Air compressors used with the tool must comply with the appropriate
UK/EU 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 (over 8 metres), is required, 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.
WARNING: COMPRESSED AIR CAN BE DANGEROUS. ENSURE THAT YOU
ARE FAMILIAR WITH ALL PRECAUTIONS RELATING TO THE USE OF
COMPRESSORS AND COMPRESSED AIR SUPPLY.

• The minimum hose diameter should be 3/8”(10mm) ID and fittings
should have the same internal dimensions.
• 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.

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. Remove the
oil fill screw from the side of the
mini oiler and fill with Air-line Oil
available from your CLARKE
dealer. Replace the screw
before using the 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 strainer 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.
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 dealer.)
WARNING: COMPRESSED AIR CAN BE DANGEROUS. ENSURE THAT YOU
ARE FAMILIAR WITH ALL PRECAUTIONS RELATING TO THE USE OF AIR
COMPRESSORS AND COMPRESSED AIR SUPPLY.

jaws are open sufficiently to take
the drill bit.
4. Place the drill shank into the jaws
of the chuck.
5. Close the chuck jaws and tighten
to grip the drill bit by turning the
chuck key as shown.
6. Make sure that the chuck jaws are
fully closed and that the drill bit is
held firmly.
7. Your air drill is now ready for use.
OPERATING THE AIR DRILL
1. Squeeze the trigger to start the drill.
• Lightly position the drill bit on the workpiece and gently squeeze the
trigger.
• Once the drill is cutting and up to speed, apply a steady pressure to
drill into the workpiece.

MAINTENANCE
DAILY
• Before use, drain water from the air tank, air line and compressor.
• Pour a few drops of airline oil into the air inlet. This should be carried
out regardless of whether or not an in-line mini oiler is used. If an in-
line mini oiler is not used, this procedure should be repeated after
every two to three hours of use.
WEEKLY
• Check the air inlet screen filter
for blockage and clean if
necessary.
CLEANING
1. Keep the body of the tool clean
and free from debris.
2. 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.
3. After extensive use, remove the inlet screen filter and flush out the
mechanism with gum solvent oil or an equal mixture of SAE No10 oil and
paraffin. Allow to dry before use.
5. If the tool runs erratically or becomes inefficient, and the air supply is of
good quality, it may be necessary to dismantle the air motor and replace
worn or damaged parts. You may prefer to take the drill to your CLARKE
dealer if internal maintenance is required.
This air tool has been designed to give long and trouble free service. If,
however, having followed the instructions in this booklet carefully (refer to
page 11-Troubleshooting) , you encounter problems, take the unit to your
local CLARKE dealer.
WARNING: MAKE SURE THAT THE DRILL IS DISCONNECTED FROM THE AIR
SUPPLY BEFORE STARTING ANY CLEANING OR MAINTENANCE
PROCEDURES.

TROUBLESHOOTING
PERFORMANCE
Please note 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 air-line, or the use of connectors of improper size
or poor condition which will reduce air supply.
STORAGE
If the tool is to be stored, or is idle for longer than 24 hours, run a few drops of
air line oil into the air inlet, and run the tool for 5 seconds in order to lubricate
the internal parts.
SYMPTOM PROBLEM SOLUTION

speed but slows down
under any load.
1. Excessive pressure on
