COMPRESSED AIR REQUIREMENTS

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.

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

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 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.

BEFORE USE

NOTE: Ensure the compressor is turned off.

1. Remove the blanking plug from the inlet port 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.

INSTALLING THE COLLET

1. Select the grinding stone you

require.

2. Three 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 a different 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.

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.

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

FITTING THE GRINDING STONE

IMPORTANT: Never use chipped or cracked grindstones. Only use

grindstones 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.

OPERATING THE DIE GRINDER

1. Use your thumb to slide the

throttle locking lever forward while

squeezing the trigger against the

body of the tool.

2. The speed is dependant upon

how hard the trigger is depressed.

The trigger cannot be locked on

and has a lock-off device to

prevent accidental starting.

3. Do not use excess pressure on the

grinding stone as this will shorten its life.

4. Release the trigger to stop the grinder.

• The tool will continue to rotate very briefly after the trigger has been

released.

5. Always ensure the grinder 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.

TROUBLESHOOTING

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, ensure the blanking plug is replaced on the airline

connector once the airline is disconnected.
