to do the work of a larger industrial tool. There are certain applications for which
this tool was designed. It will do the job better and more safely at the rate for which

goggles and appropriate hearing protection. Wear a full face shield if you are
producing metal lings or wood chips. Wear an ANSI approved dust mask
or respirator when working around metal, wood, and chemical dusts and
mists. Other people in the work area must also wear ANSI approved impact safety
goggles.
9. Maintain tools with care. Keep tools clean for better and safer performance. Follow
instructions for lubricating and changing accessories. Inspect tool cords and air
hoses periodically and, if damaged, have them repaired by an authorized technician.
The handle must be kept clean, dry, and free from oil and grease at all times. Do
not operate a tool if any portion of the tool’s operating controls are inoperable,
disconnected, altered or not working properly.
10. Disconnect Air Hose and release any built-up air pressure. Never service the
Nailer, clear jams, or disassemble with the air hose attached. Always release any
built-up air even after disconnecting hose. Disconnect the Nailer 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 attaching to an air source.
12. Avoid unintentional starting. Be sure the trigger is in the Off position when not
in use and before plugging in. Do not carry any tool with your nger on the trigger,
whether it is attached to an air source or not. Do not point the tool towards yourself
or anyone whether it contains fasteners or not.

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 xtures; and any other condition that may affect proper operation.

impaired while taking drugs. If there is any doubt, do not operate the tool.
18. Use proper size and type extension cord. If an extension cord is required, it must
be of the proper size and type to supply the correct current to the compressor without
heating up. Otherwise, the extension cord could melt and catch re, or cause electrical
damage to the tool. Check your air compressor’s manual for the appropriate size cord.
It is also possible that the use of an extension cord may cause your circuit breaker to
trip or your panel fuse to break. If this happens, either use the compressor without
an extension cord or nd a larger amperage circuit to use.

tool. Always assume that the tool contains fasteners.
22. Disconnect air supply before loading Nailer. Before reloading (or making any
adjustments to) the Nailer make sure that the compressed air is disconnected.
23. Fire nails into an appropriate work surface only. Do not attempt to re nails into
surfaces too hard to penetrate. Do not drive nails on top of other nails, or at too steep
of an angle. Nails can ricochet causing personal injury. Never re the Nailer into the
