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.

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. This check should be done by inserting a touch-type
tachometer into the collet of the tool without an abrasive product
mounted.

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 tool 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 tool.

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.

23. Operators and maintenance personnel should be able to handle the bulk,

weight and power of the tool.

24. For overhead work, wear a safety helmet.
25. Be aware that the tool will continue to run after the release of the start

handle.

26. When using die grinder, the operator should adopt a comfortable posture

whilst maintaining a secure footing and avoiding awkward or off-balance
postures. The operator should change posture during extended tasks;
this can help avoid discomfort and fatigue.

27. Slips, trips and falls are major causes of workplace injury. Be aware

of slippery surfaces caused by the tool and also of the trip hazards
associated with air lines.

28. Proceed with care in unfamiliar surroundings. There can be hidden

hazards such as electricity lines or gas pipes.

29. Whipping hoses can cause severe injury.
30. Whenever universal twist couplings (claw couplings) are used, lock pins

shall be installed and whip check safety cables shall be used to safe
guard against the possible hose-to-tool connection failure.
