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. A typical airline 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.
AIR SYSTEM LAYOUT:
| 1. Air Tool 2. Air Hose 3. Oiler 4. Pressure Regulator 5. Filter 6. Shut Off Valve 7. Whip Hose 8. Coupler Body And Connector | 9. Drain Valve 10. 1/2″ Or Larger Pipe And Fitting 11. Air Dryer 12.1″ Or Larger Pipe And Fitting 13. Air Compressor 14. Auto Drain 15. Drain Valve |
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 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
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.
- Remove the plastic blanking plug from the air inlet connection
- Pour 2-3 drops of CLARKE airline oil into the inlet port. This should be done regardless of whether or not a lubricated air supply is to be used.
- If required, connect an in-line mini oiler to the tool.
A mini oiler helps to prolong the life of any air tool.
- Connect a suitable hose as shown or use the inlet connector supplied to connect directly to the hose.
- Connect the other end of the hose to the compressor.
· PTFE tape may be useful for sealing threaded connections. - Turn on the air supply and check for air leaks. Rectify any found before proceeding.
- If using a mini oiler, place a sheet of paper next to the exhaust port and squeeze the trigger for approximately 30 seconds. The oil volume is correctly set when a light stain of oil can be seen on the paper. Excessive oil should be avoided.
Your die grinder is now ready for use.
INSTALLING THE COLLET
- Select the grinding stone you require.
- Two collets of different sizes are provided. Select whichever fits the shank of the stone you have chosen.
· The larger collet may already be installed in the grinder. - 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.
- Slip the shank of the chosen stone into the collet and tighten the screw cap finger tight.
- Place the smaller of the two wrenches over the collet seat to stop the tool from rotating.
- 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 numbers on the speed control knob indicate the speed setting when aligned with the reference mark on the air inlet. Speeds available are (+/-10%):
| 1 | 11,000 rpm |
| 2 | 15,000 rpm |
| 3 | 18,000 rpm |
| 4 | 20,000 rpm |
OPERATING THE DIE GRINDER
- Slide the throttle locking lever forward while squeezing the trigger against the body of the tool.
- Do not use excess pressure on the grinding stone as this will shorten its life.
- Release the trigger to stop the grinder.
· The tool will continue to rotate for a short time after the trigger has been released. - 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
- Do not disconnect the air hose until the supply is isolated at a shut-off valve.
- Once the pressure has been isolated, disconnect the air supply hose from the air tool.
- Shut down the compressor at the end of the work session.
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 in a safe, dry place. When storing, replace the blanking plug to the air inlet once the airline is disconnected. Avoid storing the tool where the temperature is below 0oC.

MAINTENANCE
WARNING: MAKE SURE THAT THE AIR TOOL IS DISCONNECTED FROM THE AIR SUPPLY BEFORE STARTING ANY CLEANING OR MAINTENANCE.
DAILY
- Before use, drain water from the air tank, airline, and compressor.
- If no line lubricator or mini oiler is used, ensure that oil is applied to the tool on a daily basis through the air inlet connection. Run a few drops of oil through the tool before use. It may be entered into the tool air inlet, (ensuring the strainer is clear), or into the hose at the nearest connection to the air supply. Then operate the tool.
- This procedure should be repeated after every two to three hours of use or at the start of the working day. 4. Keep the body of the tool clean and free from debris.
WEEKLY
- Check the air inlet screen filter for blockage and clean if necessary.
CLEANING
- Grit or gum deposits inside the tool may also reduce its efficiency.
- After extensive use, remove the inlet screen filter and flush out the mechanism with gum solvent oil or an equal mixture of CLARKE airline oil and paraffin. Allow to dry before use.
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.
- If the tool still 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.
GREASING
The right-angle drive is fitted with a grease nipple to provide a facility for lubrication of the drive gears.
- After extensive use, apply a shot of general-purpose grease using a suitable grease gun.
PERFORMANCE
