* Declared noise levels; measurements carried out in accordance with standard EN ISO 15744.
** Declared vibration levels in accordance with EN12096; measurements carried out in accordance with standard EN ISO 8662-13.
IMPORTANT NOTE: The noise and vibration values stated in the table are from laboratory testing in conformity with stated codes and standards and are not sufficient risk evaluation for all exposure scenarios. The actual exposure values and amount of risk or harm experienced to an individual is unique to each situation and depends 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. 3M cannot be held responsible for the consequences of using declared values instead of actual exposure values for any individual risk assessment.
Operating / Maintenance Instructions
PRIOR TO THE OPERATION
The tool is intended to be operated as a hand held tool. It is always recommended that while using the tool, operators stand on a solid floor, in a secure position with a firm grip and footing. Be aware that the sander can develop a torque reaction. See the section in SAFETY PRECAUTIONS in.
Use a clean lubricated air supply that will give a measured air pressure at the tool of 6.2 bar (90 psig) 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. Connect the tool to the air supply as shown in Figure 1. Do not connect the tool to the airline system without an easily accessible air shut off valve. 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. In any case appropriate air pressure regulators shall be used at all times while operating this tool where the supply pressure exceeds the marked maximum of the tool. Details of such equipment can be obtained for your tool distributor. If such equipment is not used, 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 3M™ Air Tool Lubricant PN 20451, Fuji Kosan FK-20 or Mobil ALMO 525 into the hose end (inlet) of the tool. Reconnect tool to the air supply and run 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 be 6.2 bar (90 psig) while the tool is running so the maximum RPM is not exceeded. The tool can be run at lower pressures but should never be run higher than 6.2 bar (90 psig). If run at lower pressure the performance of the tool is reduced.

Safety Precautions
1.Read all instructions before using this tool. All operators must be fully trained in its use and aware of these safety rules.
2.The tool RPM should be checked on a regular basis to ensure proper operating speed.
3.Make sure the tool is disconnected from the air supply. Select a suitable abrasive and secure it to the disc pad or spindle. Be careful to center the abrasive on the disc pad.
4.Always wear required safety equipment when using this tool.
5.Always remove the air supply to the sander before fitting, adjusting or removing the abrasive or disc pad.
6.Always adopt a firm footing and grip and be aware of torque reaction developed by the sander.
7.Use only 3M approved spare parts.
8.Always ensure the material being worked is firmly fixed to avoid movement.
9.Check 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.Dust can be highly combustible.
11.If tool is serviced or rebuilt check to ensure that the maximum tool RPM is not exceeded and that there is no excessive tool vibration.
12.Do not exceed maximum recommended air pressure. Use safety equipment as recommended.
13.Prior to installing any shaft mounted abrasive or sanding or grinding accessory, always check that its marked maximum operating speed is equal or higher than the rated speed of this tool.
14.The tool is not electrically insulated. Do not use where there is a possibility of contact with live electricity, gas pipes, and/or water pipes.
15.This tool is not protected against hazards inherent in cutting operations, and no such cutting products should ever be attached.
16.Take care to avoid entanglement with the moving parts of the tool with clothing, ties, hair, cleaning rags or loose hanging objects. If entangled, stop air supply immediately to avoid contact with moving tool parts.
17.Keep hands clear of the spinning pad or spindle during use.
18.If the tool appears to malfunction, remove from use immediately and arrange for service and repair.
19.Do not allow the tool to free spin without taking precautions to protect any persons or objects from the loss of the abrasive or pad ruptures.
20.Immediately release the start handle in the event of any disruption of pressure; do not attempt to re-start until the disruption has been corrected.
21.When tool is not in use, store in a clean, dry environment free of debris.
22.Recycle or dispose of tool according to Local, State, and Federal regulations.

3M™ Die Grinder
3M™ Die Grinder accessories are designed for use on 3M Die Grinders. Constructed from premium, industrial-quality materials, their durability and precise construction are the ideal complement to the performance of the 3M Die Grinder. See Product Configuration/Specifications table for the correct replacement pad for a particular model.
See 3M ASD Accessory catalog 61-5002-8098-9 and 61-5002-8097-1 for additional Accessories.
Removing and remounting shanks and shaft mounted abrasive products into collet chuck
1.Disconnect air line from tool.
2.Remove currently mounted shaft accessory, shank or abrasive product from collet chuck* by using the two wrenches supplied with the tool. Use the wrench to secure the collet body while turning the collet nut counter clockwise.
3.After the existing product has been removed from the collet, inspect the collet insert to ensure that is free of debris and undamaged.
4.Fully insert the new shaft mounted accessory, shank or abrasive product into the collet.
5.Secure the collet body with the wrench and tighten the collet nut securely. Always use the correct sized collet with the matching shank (use 1/4 in collet insert with 1/4 in shafts or 6 mm collet insert with 6 mm shafts). An inadequately inserted shank could bend or break causing damage to the tool and work piece and possible injury to the operator or bystanders.
Note: During the above steps, ensure that all hardware and abrasive products are mounted concentrically on the supporting accessory.
*In the drawings on the Parts Pages, Figures 1, 2 and 3 comprise the Collet Chuck.
