8. Check hoses for leaks or worn conditions before use, and ensure that all connections are secure.

9. Do not use the tool for any other purpose than that described in this manual.

10. Keep the air supply hose away from heat, oil, and sharp edges.

11. Do not fit the tool to any stand or clamping device that may damage it.

OVERVIEW

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.

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.

• 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 meters), 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.
• 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

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 blanking plug from the air inlet 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.

6. 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).

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 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 graduations on the speed control indicate the speed setting when aligned with the reference mark on the air inlet.
   • Speeds available are: 8000, 11500, 17500 or 20000 rpm (+/10%).

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. 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 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.

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 the air supply, clean the tool, and store it in a safe, dry place. When storing, ensure the blanking plug is replaced on the airline connector once the airline is disconnected.

TROUBLESHOOTING

pressure on the tool.
2. Motor parts are worn.
3. Worn or sticking mechanism due to lack of lubricant.| 1. Reduce the force applied to the tool.
2. Return to Clarke dealer for repair.
3. Drip air tool lubricating oil into the air inlet. Allow the oil to soak moving parts before using.
The tool runs slowly. Air flows weakly from the exhaust.| 1. Motor parts jammed with gum/dirt.
2. Regulator in the closed position.
3. General airflow blocked by dirt.| 1. Examine the inlet air filter for cleanliness.
2. Adjust the regulator to an open position.
3. Operate tool in short bursts.
The tool will not run. Air flows freely from the exhaust.| 1. Motor vanes stuck due to buildup of foreign material.| 1. Disconnect air supply and rotate tool assembly manually.
2. Try operating the tool in short bursts.
3. Drip a few drops of air tool lubricating oil into the air inlet to soak moving parts.
The tool will not shut off.| 1. Throttle 0-rings damaged or ill-fitting in the seat.| 1. Return to Clarke dealer for repair.

MAINTENANCE

WARNING: MAKE SURE THAT THE AIR TOOL IS DISCONNECTED FROM THE AIR SUPPLY BEFORE STARTING ANY CLEANING, OR MAINTENANCE PROCEDURES.
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 inline mini oiler is not used, this procedure should be repeated after every two to three hours of use.

WEEKLY

1. 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 inside the tool may also reduce its efficiency. This condition can be corrected by cleaning out the air strainer 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.

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.

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 affect 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.

ACCESSORIES
A wide range of accessories is available including filter/regulators, lubricators, high-pressure hoses (5 to 50 meters), etc.
Contact your CLARKE dealer for further information or CLARKE International Service Department.
