COMPRESSED AIR LINES

AIR SUPPLY 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 air drill 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 air drill. 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), line pressure
may need to be increased.
• Never exceed the maximum operating pressure for the air drill.
• The air hose must be rated at least 150% of the maximum operating
pressure of the tool.
A typical airline layout is shown below. If an automatic in-line filter/regulator/ lubricator unit is used it will keep the tool in good condition, but should be regularly checked and topped up with oil.
7
Page 8
IMPORTANT: If a filter/lubricator unit is not used, the air tool should be lubricated with 2 to 6 drops of oil, at least once a day or after 2 hours work, depending upon the working environment. The oil can be inserted through the airline connection point.
AIRLINE SAFETY
• Never exceed the maximum operating pressure for the tool. A
pressure of 90 psi with a flow of 16 cfm is required. Too high an air pressure will shorten the life of the tool due to excessive wear.
• The air hose must be rated at least 150% of the maximum operating
pressure of the tool.

BEFORE USE

WARNING: COMPRESSED AIR CAN BE DANGEROUS. ENSURE THAT YOU ARE FAMILIAR WITH ALL PRECAUTIONS RELATING TO THE USE OF COMPRESSORS AND COMPRESSED AIR SUPPLY.
NOTE: Ensure the compressor is turned off.
1. Remove the travel plug from the airline socket.
2. 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.
3. Connect a suitable hose to the air drill as shown, using the adapter supplied if required.
4. Connect the other end of the hose to the compressor.
5. Turn on the air supply and check for air leaks. Rectify any found before proceeding
You can fit a whip hose with a quick fit coupling if required (available from your Clarke dealer.)

The handle can be located at any position around the drill by loosening the handle grip and re-tightening to secure in position.

INSERTING/REMOVING THE DRILL BIT

1. Open the chuck jaws by inserting the chuck key in one of the holes in the chuck and turning it as shown.
2. Make sure that the head of the chuck key is located on the barrel of the chuck.
3. Turn the chuck key until the chuck jaws are open sufficiently to take the drill bit.
4. Place the drill bit in the jaws of the chuck as far as it will go.
5. Close the chuck jaws and tighten to grip the drill bit by turning the chuck key as shown.
6. Make sure that the chuck jaws are fully closed and that the drill bit is held firmly.
7. Your air drill is now ready for use.

OPERATION

OPERATING THE AIR DRILL

WARNING: MAKE SURE THAT THE CHUCK KEY HAS BEEN REMOVED BEFORE USING THE DRILL.
1. Squeeze the trigger switch to start the drill.
2. Wait until the drill is running at its maximum speed before applying it carefully to the workpiece.
3. Release the trigger switch to stop the drill.
4. To change the direction of rotation move the lever on the left side of the drill body from F to R.
5. Always ensure the drill has stopped before putting it down.

DISCONNECTING THE AIR SUPPLY

Do not disconnect the air supply hose until the compressor has been shut down and the compressed air pressure released.
1. Refer to the compressor instruction book for the procedures to shut down and release the compressed air.
2. Once the pressure has been released, disconnect the air supply hose from the air drill.

STORAGE

1. Store the air drill safely in a dry, secure environment.
2. If the tool is not to be used for longer than 24 hours, run a few drops of CLARKE airline oil into the air inlet and run the tool for a few seconds to ensure that the oil has been well distributed throughout the tool.
3. When storing, ensure the blanking plug is replaced on the airline inlet connector once the airline has been disconnected.

MAINTENANCE

WARNING: MAKE SURE THAT THE AIR DRILL IS DISCONNECTED FROM THE AIR SUPPLY BEFORE STARTING ANY CLEANING, OR MAINTENANCE PROCEDURES.

DAILY

• Drain any water from the air tank, airline, and compressor.
• Pour a few drops of CLARKE air line oil, into the air inlet. This should be
carried out regardless of whether or not an air line lubricator is used. If an airline lubricator is not used, this procedure should be repeated after every two to three hours of use.

WEEKLY

• Check the air inlet screen filter and clean if
necessary. It may be necessary to unscrew the air inlet connector to achieve this.

CLEANING

• Keep the body of the air drill clean and free
from debris, grit or gum deposits in the tool may reduce efficiency.
• After extensive use, remove the inlet screen
filter and flush out the mechanism with gum solvent oil or an equal mixture of SAE No10 oil and paraffin. Allow to dry before use.

SERVICE AND REPAIR

• Major servicing and repairs should be carried out by a qualified service
technician.

PERFORMANCE

• Please note that factors outside the tool may effect its operation and
efficiency such as reduced compressor output, excessive drain on the airline, moisture or restrictions in the 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
