Read all instructions before using this tool!
1. Keep work area clean. Cluttered areas invite injuries.
2. Observe work area conditions. Do not use in damp or wet locations. Don’t expose to rain. Keep work area well
lighted. Do not use in the presence of flammable gases or liquids.
3. Keep children away. Children must never be allowed in the work area. Do not let them handle this product or other
machines, tools, or extension cords.
4. Store idle equipment. When not in use, this product must be stored in a dry location to inhibit rust. Always lock up and
keep out of reach of children.
5. Use the right tool for the job. Do not attempt to force a small tool or attachment to the work of a larger industrial tool.
There are certain applications for which this product was designed. It will do the job better and more safely at the rate
for which it was intended. Do not modify this product and do not use this product for a purpose for which it was not
intended.
6. Do not overreach. Keep proper footing and balance at all times. Do not reach over or across running machines.
7. Dress properly. Do not wear loose clothing or jewelry as they can be caught in moving parts. Protective, electrically
nonconductive clothes and nonskid footwear are recommended when working. Wear restrictive hair covering to
contain long hair.
8. Use eye and ear protection. Always wear ANSI-approved impact safety goggles when using and servicing this
product and/or air tools. Wear a full face shield if you are producing metal filings or wood chips. Wear a NIOSH-
approved dust mask or respirator when working around metal, wood, and chemical dusts and mists.
