2. Avoid contact with the moving sanding belt and wear suitable gloves to
protect the hands.

3. Never run the sander unless the abrasive belt is applied to the workpiece.

4. Beware of potentially explosive atmospheres being caused by dust / fumes
resulting from sanding and used dust extraction systems where possible.

5. Always wear a face mask when using the sander as protection from
airborne particles of sanded material. Avoid disturbing existing dust and
minimise the scattering of dust in the workplace environment. Take steps to
control the dust at the point of emission.

TRANSPORTATION

1. Never carry the sander by the air supply hose.

2. Never carry the sander with your finger on the trigger.

THE COMPRESSED AIR SUPPLY

AIR SUPPLY 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 airline 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.

• The minimum hose diameter should be 5/16”(8mm) ID and fittings

should have the same internal dimensions.

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

• Never exceed the maximum operating pressure for the tool. It is

recommended that air pressure to this tool does not exceed 90 psi
(6.2 bar) 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

INSTALLING THE BELT

1. To install or replace sanding belt,
push the arm/idler assembly
towards the body of the tool
against the resistance of the spring
until it latches.

2. The belt can now be removed and
refitted.

3. Ensure the belt is correctly tracking
on the rollers before pressing the
release catch to release the spring
loaded arm. This will re-tension the belt.

ADJUSTING THE ANGLE OF THE SANDER

1. To adjust the working angle of the
sander, slacken the hex headed
screw using the hex key supplied
and set the sander arm to the
required position, then secure by
re-tightening the hex screw.

• Only use sanding belts

designed for use with this type of
sander.

CONNECTING THE AIRLINE

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

1. Remove the protective plug from
the air inlet port and connect a
suitable hose as shown.

2. Connect the other end of the hose
to the compressed air supply.

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

• PTFE tape may be useful for

sealing threaded connections.

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

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

5. 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 airline inlet or via the hose at the
nearest connection to the air supply.

6. A gauze filter is fitted within the air inlet. Ensure this filter is always in place
and is kept clean. An airline is connected to the adapter, preferably via a
quick release coupling (not supplied).

7. Ensure the trigger is NOT depressed when connecting the airline.

• 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.)

OPERATION

OPERATING THE SANDER

1. Ensure your fingers are clear of the sanding belt.

2. To begin work, rest the belt on the workpiece and gently start the sander.

3. Squeeze the throttle lever against the body of the tool to start the sander.

8

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

• Let the tool do the work. The actual weight of the sander is normally

sufficient for efficient sanding. Do not put additional pressure on the
sander, which would only slow down the speed of the belt, reducing
efficiency and placing an additional burden on the motor.

4. Take care to keep the sander moving around at all times. Avoid dwelling in
one place for more than a moment.

5. When finished sanding, release the throttle lever and allow the motor to
stop before carefully putting the tool down.

DISCONNECTING THE AIR SUPPLY

1. Do not disconnect the air supply hose until the air supply 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 sander.

MAINTENANCE

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

Please note that factors other than the tools condition may effect its operation
and efficiency, such as reduced compressor output, excessive drain on the
airline, moisture or restrictions in the airline, or the use of connectors of
improper size or poor condition which will reduce the air supply.

DAILY

1. Before use, drain water from the airline and compressor.

2. Lubricate the air tool daily for optimum performance. Use a high quality
airline oil either via a lubricator in the air supply system or by placing a few
drops into the air inlet immediately before use. This should be carried out
regardless of whether or not an in-line lubricator is used.

CLEANING & OVERHAUL

1. Keep the moving parts clean and free from debris.

2. If the sander becomes sluggish and the air supply is of good quality, it may
be necessary to replace worn or damaged parts.

3. Grit or gum deposits in the
mechanism may eventually
reduce efficiency. This condition
can be corrected by cleaning the
air inlet filter and flushing out the
tool with gum solvent oil or an
equal mixture of SAE No10 oil and
paraffin.

4. Failing this, the tool should be
disassembled, thoroughly
cleaned, dried and reassembled.
You may prefer to take the tool to your CLARKE dealer if internal
maintenance is required.

STORAGE

If the tool is to be stored or is idle for longer than 24 hours, run a few drops of
Clarke airline oil into the air inlet and depress the trigger in order to lubricate
the internal parts.

When not in use, the tool should be disconnected from the air supply and
stored in a dry place out of the reach of children. Avoid storing in a damp
environment.

ACCESSORIES

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