SANDER-SPECIFIC SAFETY RULES

1. Avoid contact with the moving sanding disc and wear suitable gloves to

protect the hands.

2. Never run the tool unless the abrasive disc is applied to the workpiece.

3. Beware of potentially explosive atmospheres being caused by dust / fumes

resulting from sanding and used dust extraction systems where possible.

4. 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 AND STORAGE

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

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

3. When not in use the tool must be disconnected from the air supply and

stored in a dry place out of the reach of children (preferably in a locked

cabinet).

COMPRESSED AIR REQUIREMENTS

• 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.

WARNING: COMPRESSED AIR CAN BE DANGEROUS. ENSURE THAT YOU

ARE FAMILIAR WITH ALL PRECAUTIONS RELATING TO THE USE OF

COMPRESSORS AND COMPRESSED AIR SUPPLY.

When opening the carton for the first time, check against the following list that

all the items are present. Any damage or deficiency should be reported to

your CLARKE dealer immediately.

FITTING THE SANDING DISC

1. Remove the flange nut.

2. Fit the backing disc, ensuring the hole in the disc sits snugly over the

shoulder on the flange nut.

3. Refit the flange nut, finger tight.

• Ensure the shoulder on the flange nut fits inside the hole on the

backing disc.

REPLACEMENT DISCS

NOTE: Common sanding discs with 22 mm bore are used and are

available from a Clarke dealer.

NOTE: IMPORTANT: Only use abrasive sanding pads designed for use with

this type of sanding pad.

CONNECTING THE AIR SUPPLY

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.

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 air inlet or via the hose at the

nearest connection to the air supply.

3. Connect a suitable hose to the air inlet and the other end of the hose to

the compressor.

4. 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).

USING THE SANDER

Squeeze the trigger against the body of the tool to start and evaluate its

speed. The regulator valve can be used for setting positive speed control.

1. To begin work, rest the disc pad on the workpiece and start the sander.

• 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 pad, reducing

efficiency and placing an additional burden on the motor.

2. Gently offer the abrasive disc to work piece, DO NOT FORCE IT, allow the

tool to do the work for which it was designed.

3. Pass the sander back and forth in wide, overlapping areas, taking care to

keep the sander moving around at all times. Avoid dwelling in one place

for more than a moment.

4. Release the trigger to stop the tool.

5. Always ensure the tool has stopped before putting it 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

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 in-

line mini oiler is not used, this procedure should be repeated after every

two to three hours of use.

CLEANING

1. Keep the body of the 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 inside the air

inlet, 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.

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.

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.

WARNING: MAKE SURE THAT THE AIR TOOL IS DISCONNECTED FROM THE

AIR SUPPLY BEFORE STARTING ANY CLEANING, OR MAINTENANCE

PROCEDURES.
