Before Operating
Before operating your Air Hand Nailer, check for damaged parts.
Never force the tool or attachment to do the work of a larger industrial tool. It is designed to do
the job better and more safely at the rate for which it was intended.
Do not try to use inappropriate attachments in an attempt to exceed the tool’s capacity. Approved accessories
are available from Harbor Freight Tools.
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.
Never drive fasteners on top of other fasteners as the fastener may deflect, resulting in injury.
Assembly
Your Air HandNailercomes completely assembled.
Air connection
Step 1) You will need a Union fitting (sold separately) before you can connect your Air
Hand Nailer to an air compressor. Attach the Union fitting to the Air Inlet and
tighten the fitting.
Step2) Attach an Air Coupler (sold separately) to the Union fitting if desired. This is a useful
accessory as it allows quick-coupling action when using a variety of tools with the same
aircompressor.
Set up
Frequent, but not excessive, lubrication is required for best performance. Oil added through the airline
connection will lubricate internal parts. An automatic airline oiler is recommended but oil may be added
manually before every operation or after about one (1) hour of continuous use. Only a few drops of oil at a time
are necessary. Too much oil will collect inside of the tool and be blown out during the exhaust cycle. Use only
Pneumatic tool oil. Do not use detergent oil or additives as these lubricants will cause accelerated wear to
#41164 REV 07/01 Page 3
Dirt and water in the air supply are major causes of pneumatic tool wear. Use a filter/oiler for better
performance and longer life of the tool. The filter must have adequate flow capacity for the specific application.
Set up (Cont’d)
Consultthe manufacturer’s instructionsforproper maintenance of yourfilter.
The connector on the tool must not hold pressure when the air supply is disconnected. If the wrong fitting is
used, the tool can remain charged with air after being disconnected and still be able to drive a fastener.
