SPECIFIC PRODUCT WARNINGS AND PRECAUTIONS
Important consumer information: This Nailer is equipped with a contact trip
1.
Trigger. This Trigger mechanism is designed primarily for high volume work where
exact placement of the nail is not critical. By holding the Trigger, the Nailer will re
each time the nosepiece contacts the wood. A characteristic of this design is the
tendency to “double re” if used to shoot one Nail at a time. This can be caused
by the recoil produced and lingering nger pressure on the Trigger. To avoid this
occurrence, hold the Nailer rmly against the wood and give the Trigger one quick
squeeze. A single shot Nailer, equipped with a sequential trip Trigger, may be
considered if high volume, rapid nailing is not required. Failure to understand its
operating characteristics, or careless use, can result in property damage and/or
serious personal injury.
Maintain a safe working environment. Keep the work area well lit. Make sure there
2.
is adequate surrounding workspace. Always keep the work area free of obstructions,
grease, oil, trash, and other debris.
Maintain labels and nameplates on the Nailer. These carry important information.
3.
If unreadable or missing, contact Harbor Freight Tools for a replacement.
Use only clean, dry, regulated, compressed air at between 85 to 115 PSI. Never
4.
use oxygen, carbon dioxide, combustible gases, or any other bottled gas as a power
source for this tool.
When connecting to the air supply: Prior to each use, if an automatic oiler is
5.
not used, add two drops of air tool oil into the Coupler Plug (part #73) of the Nailer.
Attach the air compressor hose to the Air Plug. Turn on the air compressor, and set
the regulator to the recommended 85 to 115 PSI for this tool.
Disconnect the air supply hose to the Nailer before loading the nails to prevent
6.
a nail from being accidentally red during connection. The Nailer’s driving
mechanism may cycle when the tool is connected to the air supply hose. When not in
use, remove all nails from the Fixed Magazine (part #49) of the Nailer.
To prevent accidental ring, do not load nails with the Trigger (part #37)
7.
depressed.
Remove your nger from the Trigger (part #37) when not driving nails. Never
8.
carry the tool with your nger on the Trigger. The tool will re a nail every time the
nosepiece contacts the wood.
Always assume the Nailer contains nails. Keep the tool pointed away from
9.
yourself and others at all times.
Never use the Nailer if the Trigger (part #37), or Safety Bracket (part #41), is
10.
damaged. Do not alter or remove the Safety Bracket. Make daily inspections for free
movement of the Trigger and Safety Bracket mechanism.
Grip the Nailer rmly with both hands to maintain control, while allowing the
11.
tool to slightly recoil away from the workpiece as a nail is driven.
