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 handles
must be kept clean, dry, and free from oil and grease at all times.

10.

Disconnect air supply. Disconnect air hose when not in use and always make sure that no

stored up air pressure remains in the Air Nailer/Stapler.

11.

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

removed from the tool or machine work surface before plugging it in.

12.

Avoid unintentional starting.  Do not carry any tool with your finger on the trigger, whether it

is attached to the compressor or not.

13.

Stay alert.  Watch what you are doing, use common sense. Do not operate any tool when you

are tired.

14.

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.

15.

Guard against electric shock.  Prevent body contact with grounded surfaces such as pipes,

radiators, ranges, and refrigerator enclosures.

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.

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 tool without heating up. Otherwise, the
extension cord could melt and catch fire, or cause electrical damage to the tool. Check your
compressor’s manual for the appropriate size cord.

19.

Maintenance.  For your safety, maintenance should be performed regularly by a qualified

technician.

20.

Compressed air only.  Never use combustible gases as a power source.

21.

Use on soft surfaces.  Do not use the tool on rock, concrete, metal or other hard surfaces.

You can damage the Air Nailer/Stapler and incur personal injury and property damage.

Note: Performance of the compressor (if powered by line voltage) may vary depending
on variations in local line voltage. Extension cord usage may also affect tool
performance.
