SANDER-SPECIFIC SAFETY RULES

  1. Avoid contact with the moving sanding pad and wear suitable gloves to protect the hands.
  2. Never run the tool unless the abrasive pad is applied to the workpiece.
  3. Beware of potentially explosive atmospheres being caused by dust / fumes resulting from sanding and used dust extraction systems where possible.
  4. Always wear a face mask when using the sander as protection from airbourne particles of sanded material. Avoid disturbing existing dust and minimise the scattering of dust in the worplace environment. Take steps to control the dust at the point of emission.

TRANSPORT & STORAGE

  1. Never carry the tool by the air hose.
  2. Never carry the tool with your finger on the trigger.
  3. When not in use the tool must be disconnected from the air supply and stored in a dry place out of the reach of children (preferably in a locked cabinet).
  4. Avoid storing the tool where the temperature is below 0oC

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 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 tool.

  • 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. clarke airline oil should be used, and the lubricator adjusted to approx 2 drops per minute.

  • For optimum performance it is recommended that a 3/8” ID hose is used.

  • 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 dirty air will shorten the life of the tool due to faster wear and is a possible safety hazard

BEFORE USE

CONNECTING THE AIR SUPPLY

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.

  1. 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.
  2. Connect a suitable hose to the tool as shown using the airline connector supplied with the tool.
  3. 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.
  4. 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.
  5. Connect the other end of the hose to the compressor.
  6. Turn on the air supply and check for air leaks. Rectify any found before proceeding. PTFE tape may be useful for sealing threaded connections.
  7. 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.)

FITTING THE SANDING SHEET

  • The CAT49 sander requires a minimum of 70mm x  420mm abrasive sheet. Foldthe sheet around the end of the bed and grip it in position with the spring clipat each end. Take care that it is positioned centrally.

OPERATING

  1. To begin work, rest the disc pad on the workpiece and start the sander.
    • Let the tool do the work. The actual weight of the machine is normally sufficient for efficient sanding. Do not put additional pressure on the machine, which would only slow down the speed of the pad, reducing efficiency and placing an additional burden on the motor.
  2. Pass the sander back and forth in wide, overlapping areas, taking care to keep the sander moving around at all times. Avoid dwelling in one place for more than a moment.
  3. Release the trigger to stop the tool.
  4. Always ensure the tool 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 vent the compressed air.
  3. Once the pressure has been released, disconnect the air supply hose from the air tool.

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 airline filter and compressor.
  2. Pour a few drops of Clarke air-line 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 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 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 or oil, or failing this, the tool should be disassembled, thoroughly cleaned, dried and reassembled. This is better left to your Clarke dealer.
  3. After extensive use, remove the inlet screen filter and flush out the mechanism with gum solvent or oil or an equal mixture of Clarke air-line 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 tool to your Clarke dealer if internal maintenance is required.

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.

** Clarke Air Line Oil (part no. 3050825) is available from your Clarke dealer.

Your Clarke air tool has been designed to give long and trouble free service. If, however, having followed the instructions in this booklet carefully, you encounter problems, take the unit to your local Clarke dealer.

STORAGE

When not in use, disconnect from air supply, clean & store in a safe, dry place.
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.
