SANDER-SPECIFIC SAFETY RULES

1. Inspect the sanding belt before use. Do not use if frayed.

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

protect the hands.

3. Never run the tool 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.

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. clarke airline oil should

be used, and the lubricator adjusted to approx 2 drops per minute.

• For optimum performance it is recommended that a 3/8” ID hose is

used.

• 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 dirty 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.

Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Service@clarkeinternational.com

BEFORE USE

CONNECTING THE AIR SUPPLY

1. Pour 2-3 drops of CLARKE airline oil into the air inlet. This should be done

regardless of whether or not a lubricated air supply is to be used.

2. Connect a suitable hose to the

tool as shown using the airline

connector supplied with the tool.

3. 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.

4. 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.

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

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

proceeding. PTFE tape may be useful for sealing threaded connections.

7. 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.)

ARE FAMILIAR WITH ALL PRECAUTIONS RELATING TO THE USE OF AIR

COMPRESSORS AND COMPRESSED AIR SUPPLY.

INSTALLING THE BELT

1. To replace sanding belt, push the idler pulley assembly (Item 2) towards the

handle until it clicks into the secured position. Replace the belt and press

the tension bar (item 14), to re-tension the belt (see Fig 1

2. To track the belt, adjust as required with screw and locknut (2A in Fig 1).

3. To adjust the handle position, slacken the screw (item 11), rotate the

handle to the required position. (Only as far as A or B), then secure by re-

tightening the screw (item 11).

4. Connect to the airline and turn the air on.

5. Ensure your fingers are clear of the sanding belt. Squeeze the throttle lever

to start the motor. Allow the motor to reach max speed before offering the

belt to the workpiece.

6. Do not use the finger pad (Item 4) to exert pressure on the belt; this item is

only for guiding the tool.

7. When finished sanding, release the throttle lever and allow the motor to

stop before carefully putting the tool down.

•Only use sanding belts designed for use with this type of sander

OPERATING

1. Squeeze the trigger against the body of the tool to start the sander and

control the speed. Evaluate the speed and adjust to suit.

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

Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Service@clarkeinternational.com

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

normally sufficient for efficient sanding. Do not put additional

pressure on the machine, which would only slow down the speed of

the belt, reducing efficiency and placing an additional burden on

the motor.

3. Pass the sander back and forth, 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 vent the compressed air.

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

the air tool.

MAINTENANCE

DAILY

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

2. Pour a few drops of Clarke air-line oil, into the tool 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.

3. 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

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

AIR SUPPLY BEFORE STARTING ANY CLEANING OR MAINTENANCE

PROCEDURES.

Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Service@clarkeinternational.com

gum solvent oil, or failing this, the tool should be disassembled, thoroughly

cleaned, dried and reassembled. This is better left to your Clarke dealer.

3. After extensive use, remove the

inlet screen filter and flush out the

mechanism with gum solvent oil or

an equal mixture of Clarke air-line

oil and paraffin. Allow to dry

before use.

4. f 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 tool to your Clarke dealer if

internal maintenance is required.

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.

Your Clarke air tool has been designed to give long and trouble free service. If,

however, having followed the instructions in this booklet carefully, you

encounter problems, take the unit to your local Clarke dealer.

STORAGE

When not in use, disconnect from air supply, clean & store in a safe, dry place.

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.

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.
