DRILL SAFETY PRECAUTIONS

1. ALWAYS make sure the work surface is free from nails and other foreign objects.
2. After changing bits and accessories or making adjustments, make sure the chuck is securely tightened and that the chuck key has been removed.
3. ALWAYS check bits for damage before each use. Damaged bits or other accessories can break during use and cause serious injury.
4. NEVER use dull or damaged bits. Sharp bits must be handled with care. Damaged bits can snap during use. Dull bits require more force possibly causing the bit to break.
5. Use of a dust collection system reduces dust-related hazards.
6. Maintain a firm grip on the tool and position your body and arms to allow you to resist kickback forces. Kickback will propel the tool in the direction opposite to the tool’s movement at the time of snagging.
7. Use metal and voltage detectors to locate hidden electric. water or gas lines. Avoid touching live components or conductors.
8. Before drilling, check that there is sufficient clearance for the drill bit under the workpiece.
9. If you are interrupted when operating the drill, switch off the tool before looking up.

TRANSPORT

THE COMPRESSED AIR SUPPLY

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.
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. 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 compressors used with the tool must comply with the appropriate UK/EU 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 (over 8 metres), is required, 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.
• The minimum hose diameter should be 3/8”(10mm) ID and fittings should have the same internal dimensions.
• 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. 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.
2. 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.
3. Remove the travel plug from the air inlet and connect a suitable hose as shown.
4. Connect the other end of the hose to the compressor.
5. Turn on the air supply at low pressure and check for air leaks. Rectify any found before proceeding.
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 dealer).

OPERATION

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 shank into the jaws of the chuck.
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.

OPERATING THE AIR DRILL

WARNING: MAKE SURE THAT THE CHUCK KEY HAS BEEN REMOVED BEFORE USING THE DRILL.

1. Squeeze the trigger to start the drill.
   • Lightly position the bit on the workpiece & gently squeeze the trigger.
   • Once the drill is cutting and up to speed, apply a steady pressure to drill into the workpiece.
2. Release the trigger to stop.
3. Always ensure the drill has stopped before putting it down.

SETTING FORWARD/REVERSE

1. Ensure the drill is stationary before selecting forward or reverse.
2. Set the drill to Forward (drilling) mode by pressing the button in and turning a quarter of a turn.
3. Revere this action or Reverse operation.

SAFE DRILLING WITH THE AIR DRILL

CAUTION: IMMEDIATELY RELEASE THE TRIGGER IF THE DRILL BIT BECOMES STUCK OR JAMMED, THE TOOL’S TORQUE CAN TWIST YOUR ARM AND CAUSE AN INJURY. THE TOOL MAY TWIST OUT OF YOUR GRIP AND CAUSE AN INJURY TO YOURSELF OR A BYSTANDER.

1. Verify the drill’s rotation before starting the drill.
2. A loose or mismatched bit may be ejected by the tool, causing an injury to the user or a bystander. It may also fail to penetrate the material as the point may move around under pressure, damaging the workpiece.
   • Ensure the bit shank size matches the tool’s chuck.
   • Tighten the chuck so the shank is tightly held with no room to move.
3. Always hold the tool firmly when switching on. The reaction to the motor’s torque may cause the tool to twist as it accelerates to full speed.
4. DO NOT use drill as a router or try to elongate or enlarge holes by twisting the drill. Drill bits can break and can cause injury.
5. DO NOT apply side pressure on the bit unless it is designed for such a purpose. The bit may bind or break.
6. NEVER attempt to change the rotation direction while the tool is running. Be sure the switch is OFF and the motor has completely stopped before changing the rotation direction.

DISCONNECTING THE AIR SUPPLY

DO NOT disconnect the air supply hose until the compressor has been shut down and the compressed air released.

1. Refer to the compressor instruction manual for the procedure to shut down and release the compressed air.
2. Once the pressure has been released, disconnect the air supply hose from the air drill.
3. Store the tool safely in its box in a dry, secure environment.

MAINTENANCE

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

DAILY

1. Before use, drain water from the compressor air tank and air line.
2. Pour a few drops of airline 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.

WEEKLY

1. Check the air inlet screen filter for blockage and clean if necessary.
2. Applying grease to the head assembly is recommended to prolong the life of the tool. Press your grease gun nozzle against the grease nipple on the side of the drill to inject a shot of grease. Run the tool for a few moments to distribute the grease internally.

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 gum solvent oil, or failing this, the tool should be disassembled, thoroughly cleaned, dried and reassembled.
3. 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.
4. If 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 drill to your CLARKE dealer if internal maintenance is required.

This air tool has been designed to give long and trouble free service. If, however, having followed the instructions in this booklet carefully (refer to page 10 – Troubleshooting), you encounter problems, take the unit to your local CLARKE dealer.

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.

STORAGE
If the tool is to be stored, or is idle for longer than 24 hours, run a few drops of 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 & store in a safe, dry place.

ACCESSORIES
A wide range of accessories is available including filter/regulators, lubricators, high-pressure hoses (5 to 50 metres) etc.
