COMPRESSED AIR REQUIREMENTS

WARNING: COMPRESSED AIR CAN BE DANGEROUS. ENSURE THAT YOU
ARE FAMILIAR WITH ALL PRECAUTIONS RELATING TO THE USE OF
COMPRESSORS AND COMPRESSED AIR SUPPLY.

• 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.

BEFORE USE

WARNING: COMPRESSED AIR CAN BE DANGEROUS. ENSURE THAT YOU
ARE FAMILIAR WITH ALL PRECAUTIONS RELATING TO THE USE OF AIR
COMPRESSORS AND COMPRESSED AIR SUPPLIES.

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).

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.

SETTING THE SPEED

1. Adjust the tool speed by setting
the air regulator on top of the tool
body using a suitable screwdriver.

OPERATING THE TOOL

1. Use your thumb to slide the
throttle locking lever forward while
squeezing the trigger against the
body of the tool.

2. Do not use excess pressure on the
grinding stone as this will shorten
its life.

3. Release the trigger to stop the
tool.

• The tool will continue to rotate

very briefly after the trigger has been released.

4. Always ensure the tool has stopped before putting it down.

GRINDING TIPS

• The key to efficient grinding is to control the pressure and surface

contact between the grinding tool and the workpiece.

• Allow the tool to reach full speed before grinding.

• Avoid overloading the die grinder. If it becomes hot during use, rest

for a few minutes while it cools down.

DISCONNECTING THE AIR SUPPLY

1. Do not disconnect the air supply hose until the compressor has been shut
down and the compressed air released.

2. Refer to the compressor instruction manual for the procedure to shut down
and release the compressed air.

3. Once the pressure has been released, disconnect the air supply hose from
the tool.

MAINTENANCE

WARNING: MAKE SURE THAT THE AIR TOOL IS DISCONNECTED FROM THE
AIR SUPPLY BEFORE STARTING ANY CLEANING OR MAINTENANCE
PROCEDURES.

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.

**Clarke Air Line Oil (part no. 3050825) is available from your CLARKE dealer.

DAILY

1. Before use, drain water from the air tank, air line and compressor.

2. Pour a few drops of CLARKE 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 in­line mini oiler is not used, this procedure should be repeated after every
two to three hours of use.

10

Parts & Service: 020 8988 7400 / E-mail: [email protected] or [email protected]

WEEKLY

1. Check the air inlet strainer for
blockage and clean if necessary.

1. Keep the body of each tool clean
and free from debris.

2. Grit or gum deposits inside the tool
may also reduce its efficiency. This
condition can be corrected by
cleaning out the air strainer and
flushing out the tool with gum
solvent or oil, or failing this, the
motor may require dismantling. This is better left to your Clarke dealer.

LUBRICATION

The right-angle drive is fitted with a
grease nipple to provide a facility for
lubrication of the drive gears.

After extensive use, apply a shot of
general purpose grease using a
suitable grease gun.

SERVICE AND REPAIR

If the tool runs erratically or becomes
inefficient although the air supply is in
good order, it may be necessary to dismantle the air motor and replace any
worn or damaged parts. Such servicing and repair work should be carried out
by a qualified service technician.

STORAGE

If the tool 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.

When not in use, disconnect from air supply, clean tools and store in the
moulded case provided. When storing, ensure the blanking plug is replaced
on the airline connector once the airline is disconnected.

ACCESSORIES

A wide range of accessories is available including filter/regulators, lubricators,
high-pressure hoses (5 to 50 metres) etc.

Contact your CLARKE dealer for further information or CLARKE International
Service Department.
