To reduce the risks associated with skin abrasion, burns, cutting & severing, impact or entrapment:

Never install and use router bits or cutting-off wheels in a die grinder tool (which is unguarded).

Keep hands, hair, and clothing away from the cutting 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 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 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.

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.

CAUTION!

To reduce the risks associated with whipping:

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.

To reduce the risks associated with flying off of accessory 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.

To reduce the risks associated with hazardous pressure or rupture:

• Be aware that incorrectly installed hoses and fittings might unexpectedly come loose at any time and create a whipping/impact hazard.
