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.

A typical air line layout is shown below. 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.

Use only clean, dry, regulated compressed air as a power source.

5

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

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 air tool.

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.

When opening the carton for the first time, check that all the items are
present. Any damage or deficiency should be reported to your CLARKE dealer
immediately.

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 SUPPLY.

NOTE: Ensure the compressor is turned off.

1. Remove the plastic blanking plug from the air inlet connection.

2. Pour 2-3 drops of CLARKE airline oil into the inlet port. This should be done
regardless of whether or not a lubricated air supply is to be used.

3. If required, connect an in-line mini oiler to the tool.

• A mini oiler helps to prolong the life of any air tool.

4. Connect a suitable hose as shown
or use the inlet connector supplied
to connect directly to the hose.

5. Connect the other end of the hose
to the compressor.

• PTFE tape may be useful for

sealing threaded connections.

6. Turn on the air supply and check
for air leaks. Rectify any found
before proceeding.

7. If using a mini oiler, place a sheet of paper next the exhaust port and
squeeze the trigger for approximately 30 seconds. The oil volume is
correctly set when a light stain of oil can be seen on the paper. Excessive
oil should be avoided.

Your die grinder is now ready for use.

INSTALLING THE COLLET

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 may already

be installed in the grinder.

3. If another 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

IMPORTANT: Never use chipped or cracked grindstones.

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.

ADJUSTING THE SPEED

1. Set the tool speed by rotating the
control to one of the four settings.

• The numbers on the speed

control knob indicate the
speed setting when aligned
with the reference mark on the
air inlet. Speeds available are
(+/-10%):

OPERATING THE DIE GRINDER

1. 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
grinder.

• The tool will continue to rotate

for a short time after the trigger has been released.

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

SETTING THE EXHAUST DEFLECTOR

The direction of the exhaust air
leaving the tool can be adjusted by
rotating the exhaust deflector.

Twist the exhaust deflector sleeve to
direct the air as required to deflect air
away from the workpiece or operator.

DISCONNECTING THE AIR SUPPLY

1. Do not disconnect the air hose until the supply is isolated at a shut-off
valve.

2. Once the pressure has been isolated, disconnect the air supply hose from
the air tool.

3. Shut down the compressor at the end of the work session.

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 tool and store in a safe, dry
place. When storing, replace the blanking plug to the air inlet once the airline
is disconnected.

Avoid storing the tool where the temperature is below 0

TROUBLESHOOTING

SYMPTOM PROBLEM SOLUTION

Tool runs at normal
speed but slows down
under any load.

Tool runs slowly. Air flows
weakly from exhaust.

Tool will not run. Air flows
freely from exhaust.

1. Excessive pressure on
tool.

2. Motor parts worn.

3. Worn or sticking
mechanism due to
lack of lubricant.

1. Motor parts jammed
with gum/dirt.

2. Regulator in closed
position.

3. General airflow
blocked by dirt.

1. Motor vanes stuck
due to buildup of
foreign material.

1. Reduce the force
applied to the tool.

2. Return to CLARKE dealer
for repair.

3. Drip air tool lubricating
oil into air inlet. Allow oil
to soak moving parts
before using.

1. Examine inlet air filter for
cleanliness and clean if
necessary.

2. Adjust regulator to open
position.

3. Operate tool in short
bursts.

1. Disconnect air supply
and rotate tool assembly
manually.

2. Try operating tool in
short bursts.

3. Drip a few drops of air
tool lubricating oil into air
inlet to soak moving
parts.

Tool will not shut off. 1. Throttle O-rings

damaged or ill-fitting
in seat.

for repair.

MAINTENANCE

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

DAILY

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

2. If no line lubricator or mini oiler is used, ensure that oil is applied to the tool
on a daily basis through the air inlet connection. Run a few drops of oil
through the tool before use. It may be entered into the tool air inlet,
(ensuring the strainer is clear), or into the hose at the nearest connection to
the air supply. Then operate the tool.

3. This procedure should be repeated after every two to three hours of use or
at the start of the working day.

4. Keep the body of the tool clean and free from debris.

WEEKLY

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

CLEANING

1. Grit or gum deposits inside the tool
may also reduce its efficiency.

2. After extensive use, remove the
inlet screen filter and flush out the
mechanism with gum solvent oil or
an equal mixture of CLARKE air­line oil and paraffin. Allow to dry before use.

SERVICE AND REPAIR

1. 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.

2. If the tool still 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.

3. You may prefer to take the tool to your CLARKE dealer if internal
maintenance is required.

GREASING

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

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

PERFORMANCE

Please note that outside factors may
effect the operation and efficiency
of the air tool.

These include reduced compressor output, excessive drain on the airline,
moisture ingress, restrictions in the air-line such as the use of connectors of
incorrect size or poor condition which will reduce the air supply.

Your air tool has been designed to give long & trouble free service. If, however,
having followed the instructions in this booklet carefully, you encounter
problems, take the unit to your local CLARKE dealer.

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.
