Intended Use
WARNING
Original Instructions
1
• 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, disc pad, and other accessories for possible damage. If damaged, replace with new abrasive product and accessories
available from 3M.
• Only use abrasive disc pads and other accessories supplied 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.
To reduce the risks 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.
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.
To reduce the risks 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 risks 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.
To reduce the risks 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.
To reduce the risks 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 risks 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.
To reduce the risks associated with fly off of abrasive product parts:
• Use care in attaching abrasive product, disc pad, 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.
