Please Read and Comply with

  1. General Industry Safety & Health Regulations, Part 1910, OSHA 2206, available from: Superintendent of Documents; Government Printing Office; Washington DC 20402
  2. Safety Code for Portable Air Tools, ANSI B186.1 available from: American National Standards Institute, Inc.; 1430 Broadway; New York, New York 10018
  3. State and Local Regulations.

Proper Use of Tool

This grinder/polisher is designed for sanding all types of materials i.e. metals, wood, stone, plastics, etc. using abrasive designed for this purpose. Do not use this grinder/polisher for any other purpose than that specified without consulting the manufacturer or the manufacturer’s authorized supplier. Do not use backing pads that have a working speed less than 10,000 rpm free speed.

Work Stations

The tool is intended to be operated as a hand-held tool. It is always recommended that the tool be used when standing on a solid floor. It can be used in any position but before any such use, the operator must be in a secure position and have a firm grip and footing, and be aware that the polisher can develop a torque reaction. See the section “Operating Instructions”.

Putting the Tool into Service

Use a clean lubricated air supply that will give a measured air pressure at the tool of 6.2 bar )90 psig( bar when the tool is running with the lever fully depressed. It is recommended to use an approved 10 mm (3/8 in.( x 8 m )25 ft) maximum length airline. It is recommended that the tool be connected to the air supply as shown in Figure 1.

Do not connect the tool to the airline system without incorporating an easy to reach and operate air shut-off valve. The air supply should be lubricated. It is strongly recommended that an air filter, regulator and lubricator )FRL( be used as shown in Figure 1 as this will supply clean, lubricated air at the correct pressure to the tool. Details of such equipment can be obtained from your supplier. If such equipment is not used then the tool should be manually lubricated.

To manually lubricate the tool, disconnect the airline and put 2 to 3 drops of suitable pneumatic motor lubricating oil such as Fuji Kosan FK-20, Mobil ALMO 525 or Shell TORCULA® 32 into the hose end )inlet( of the machine. Reconnect the tool to the air supply and run the tool slowly for a few seconds to allow air to circulate the oil. If the tool is used frequently, lubricate it on a daily basis or lubricate it if the tool starts to slow or lose power. It is recommended that the air pressure at the tool is 6.2 bar )90 psig( while the tool is running. The tool can run at lower pressures but never higher than 6.2 bar )90 psig(.

Operating Instructions

  1. Read all instructions before using this tool. All operators must be fully trained in its use and be aware of these safety rules. All servicing and repairs must be carried out by trained personnel.
  2. Make sure the tool is disconnected from the air supply. Select a suitable abrasive and secure it to the backing pad. Take care to center the abrasive on the backing pad.
  3. Always wear the required safety equipment when using this tool.
  4. When sanding always place the tool on the work then start the tool. Always remove the tool from the work before stopping. This will prevent gouging of the work due to excess speed of the abrasive.
  5. Always disconnect the air supply from the polisher before fitting, adjusting or removing the abrasive or backing pad.
  6. Always adopt a firm footing and/or position and be aware of the torque reaction developed by the polisher.
  7. Use only correct spare parts.
  8. Always ensure that the material to be sanded is firmly fixed to prevent its movement.
  9. Check the hose and fittings regularly for wear. Do not carry the tool by its hose; always be careful to prevent the tool from being started when carrying the tool with the air supply connected.
  10. Do not exceed the maximum recommended air pressure. Use safety equipment as recommended.
  11. The tool is not electrically insulated. Do not use where there is a possibility of coming into contact with live electricity, gas pipes, water pipes, etc. Check the working area before operation.
  12. Take care to avoid entanglement of the moving parts of the tool with clothing, ties, hair, cleaning rags, etc. If entangled, it will cause the body to be pulled towards the work and moving parts of the machine, which can be very dangerous.
  13. Keep hands clear of the spinning pad during use.
  14. If the tool appears to malfunction, remove from use immediately and arrange for servicing and repair.
  15. Do not allow the tool to free-speed without taking precautions to protect any persons or objects from the loss of the abrasive or pad.

  • The values stated in the table are from laboratory testing in conformity with stated codes and standards, and are not sufficient for risk evaluation. Values measured in a particular work place may be different from the declared values. The actual exposure values and amount of risk r harm experienced by an individual are unique to each situation and depend upon the surrounding environment, the way in which the individual works, the particular material being worked, work station design as well as upon the exposure time and the physical condition of the user. Mirka, Ltd. cannot be held responsible for the consequences of using declared values instead of actual exposure values for any individual risk assessment.

Troubleshooting Guide

Symptom Possible Cause Solution
Low power and/or low free speed. Insufficient air pressure. Check air line

pressure at the inlet of the Polisher while the tool is running at free speed. It must be 6.2 Bar (90 psig/620 kPa).
Clogged Muffler)s(.| See the “Housing Disassembly” section for Muffler removal. The item 51 Muffler can be back-flushed with a clean, suitable cleaning solution until all con- taminants and obstructions have been removed.
If the Muffler cannot be properly cleaned then replace it. (See the “Housing Assembly” Section).
Plugged Inlet Screen.| Clean the Inlet Screen with a clean, suitable cleaning solution. If the Screen cannot be cleaned, replace it.
One or more worn or broken Vanes.| Install a complete set of new Vanes )all vanes must be replaced for proper operation(. Coat all vanes with quality pneumatic tool oil. See “Motor Disas- sembly” and “Motor Assembly”.
Internal air leakage in the Motor Housing indicated by higher than normal air con- sumption and lower than normal speed.| Check for proper Motor alignment and Lock Ring engagement. Check for damaged O-Ring in Lock Ring groove. Remove Motor Assembly and rein- stall the Motor Assembly. See “Motor Disassembly” and “Motor Assembly”.
Motor parts worn.| Overhaul Motor. Contact authorized Mirka Service Center.
Worn or broken Spindle Bearings.| Replace the worn or broken Bearings. See “Shaft Balancer and Spindle Disassembly” and “Spindle Bearings, AirSHIELD™ and Shaft Balancer As- sembly”.
Air leakage through the Speed Control and/or Valve Stem.| Dirty, broken or bent Valve Spring, Valve or Valve Seat.| Disassemble, inspect and replace worn or dam- aged parts. See steps 2 and 3 in “Housing Disas- sembly” and steps 2 and 3 in “Housing Assembly”.
Vibration/rough operation.| Incorrect Pad| Only use Pad sizes and weights designed for the machine.
Addition of interface pad or other material.| Only use abrasives and/or interfaces designed for the machine. Do not attach anything to the Polisher Pad face that was not specifically designed to be used with the Pad and Polisher.
Improper lubrication or buildup of foreign debris.| Disassemble the Polisher and clean in a suitable cleaning solution. Reassemble the Polisher. (See “Service Manual”.)
Worn or broken rear or front Motor Bearing)s(.| Replace the worn or broken Bearings. See “Motor Disassembly” and “Motor Assembly”.
