7.

Use eye and ear protection.  Always wear ANSI approved impact safety

goggles. Wear a full face shield if you are producing metal filings or wood
chips. Wear an ANSI approved dust mask or respirator when working around
metal, wood, and chemical dusts and mists.

8.

Do not overreach.  Keep proper footing and balance at all times. Do not

reach over or across running machines.

9.

Maintain tools with care.  Keep tools maintained and clean for better and

safer performance. Follow instructions for lubricating and changing
accessories. Inspect tool cords periodically and, if damaged, have them
repaired by an authorized technician. The handles must be kept clean, dry,
and free from oil and grease at all times.

10. Disconnect air power. Disconnect tool from air supply when not in use.

11. Remove adjusting keys and wrenches.  Check that keys and adjusting

wrenches are removed from the tool or machine work surface before
connecting air supply.

12. Avoid unintentional starting.  Be sure the trigger is in the Off position when

not in use and before connecting it. Do not carry any tool with your finger on
the trigger, whether it is connected to the air supply or not.

13. Stay alert.  Watch what you are doing, use common sense. Do not operate

any tool when you are tired.

14. Take caution as some woods contain preservatives such as copper

chromium arsenate (CCA) which can be toxic. When drilling these materials
extra care should be taken to avoid inhalation and minimize skin contact.

15. Check for damaged parts.  Before using any tool, any part that appears

damaged should be carefully checked to determine that it will operate
properly and perform its intended function. Check for alignment and binding
of moving parts; any broken parts or mounting fixtures; and any other
condition that may affect proper operation. Any part that is damaged should
be properly repaired or replaced by a qualified technician. Do not use the tool
if any switch does not turn On and Off properly.

16. Replacement parts and accessories.  When servicing, use only identical

replacement parts. Use of any other parts will void the warranty. Only use
accessories intended for use with this tool. Approved accessories are
available from Harbor Freight Tools.

17. Do not operate tool if under the influence of alcohol or drugs.  Read

warning labels on prescriptions to determine if your judgment or reflexes are
impaired while taking drugs. If there is any doubt, do not operate the tool.
