WARNING
To reduce the risks associated with impact from abrasive product or tool breakup, sharp edges, hazardous pressure, rupture, vibration and noise:
• Read, understand and follow the safety information contained in these instructions prior to the use of this tool. Retain these instructions for future
reference.
• Only personnel who are properly trained should be allowed to service this tool.
• Practice safety requirements. Work alert, have proper attire, and do not operate tool under the influence of alcohol or drugs.
• Operators and other personnel must always wear protection for eyes, ears, and respiratory protection when in the work area or while operating this
product. Follow your employer’s safety policy for PPE’s and/or ANSI Z87.1 or local/national standards for eyewear and other personal protective equipment
requirements.
• Wear protective apparel, taking into consideration the type of work being done.
• Never exceed marked maximum input pressure (90psi / .62Mpa / 6.2Bars).
• Proper eye protection must be worn at all times.
• Tool shall not be operated in the presence of bystanders.
• If you notice any abnormal noise or vibration when operating the product, immediately discontinue its use and inspect for worn or damaged components.
Correct or replace the suspect component. If abnormal noise or vibration still exists, return the tool to 3M for repair or replacement. Refer to warranty
instructions.
• Never operate this tool without all safety features in place and in proper working order.
• Never over-ride or disable the safety features of the start-stop control such that it is in the on position.
• Make sure the tool is disconnected from its air source before servicing, inspecting, maintaining, cleaning, and before changing abrasive product.
• Prior to use, inspect abrasive product and accessories for possible damage. If damaged, replace with new abrasive product and accessories available from 3M.
• Only use accessories supplied or recommended by 3M.
• Use only with mounting hardware recommended by 3M; check with 3M for mounting hardware requirements.
• Always ensure that shaft diameters match internal diameters of the collet inserts.
• Maximum operating speed of abrasive products or accessories must be reduced whenever the exposed length of shaft (overhang) is longer than
corresponding 3M approved products.
• Always ensure that a minimum of 10mm shaft gripping length is observed.
• Never install and use router bits or cutting-off wheels in a die grinder tool (which is unguarded).
• Use only with abrasive products not requiring guards according to local, state and federal regulations.
• Never allow this tool to be used by children or other untrained people.
• Do not leave an unattended tool connected to air source.
• Air under pressure can cause severe injury.
• Never direct air at yourself or anyone else.
To reduce the risk of all hazards associated with vibration:
• If any physical hand/wrist discomfort is experienced, work should be stopped promptly to seek medical attention. Hand, wrist and arm injury may result
from repetitive work, motion and overexposure to vibration.
• Hold the tool with a light but safe grip, knowing that the grip must be sufficient to counter reaction forces but that a tight grip will increase the amount of
vibration transferred to the operator.
To reduce the risks associated with loud noise:
• Always wear protection for eyes, ears, and respiratory protection while operating this product. Follow your employer’s safety policy for PPE’s and/or ANSI
Z87.1 or local/national standards for eyewear and other personal protective equipment requirements.
• Always wear hearing protection while operating this tool. Follow your employer’s safety policy or local/national standards for personal protective
equipment requirements.
• Ensure the muffler material is in place.
• Dampen work pieces to reduce noise and prevent ringing.
To reduce the risk associated with fire or explosion:
• Do not operate the tool in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust. The abrasives are able to create sparks
when working material, resulting in the ignition of the flammable dust or fumes.
• Refer to MSDS of material being worked as to potential for creating fire or explosion hazard.
To reduce the risk associated with hazardous dust ingestion or eye/skin exposure:
• Use appropriate respiratory and skin protection, or local exhaust as stated in the MSDS of the material being worked on.
• Direct exhaust so as to minimize disturbance of existing dust in a dust-filled environment.
To reduce the risk associated with hazardous voltage:
• Do not allow this tool to come into contact with electrical power sources as the tool is not insulated against electrical shock.
CAUTION
To reduce the risk associated with skin abrasion, burns, cuts, or entrapment:
• Keep hands, hair, and clothing away from the rotating part of the tool.
• Wear suitable protective gloves while operating tool.
• Do not touch the rotating parts during operation for any reason.
• Do not force tool or use excessive force when using tool.
To reduce the risk associated with whipping or hazardous pressure-rupture:
• Ensure supply hose is oil resistant and is properly rated for required working pressure.
• Do not use tools with loose or damaged air hoses or fittings.
• Be aware that incorrectly installed hoses and fittings might unexpectedly come loose at any time and create a whipping/impact hazard.
• Whenever universal twist couplings (claw couplings) are used, lock-pins shall be installed and whip check safety cables shall be used to safeguard
against possible hose-to-tool and hose-to-hose connection failure.
To reduce the risk associated with fly off of abrasive product or parts:
• Use care in attaching abrasive product and mounting hardware; following the instructions to ensure that they are securely attached to the tool before use
or free-spinning.
• Never point this product in the direction of yourself or another person, or start tool unintentionally.
• Never over-tighten accessory fasteners.

* Declared noise levels; measurements carried out in accordance with standard EN ISO 15744.
# Declared vibration levels in accordance with ISO 20643 and 28927.
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 (or equivalent 10 centistoke oil) into the air 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 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.

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.
