METHODS OF OPERATION
This Nailer is equipped with the push lever and does not operate unless the push lever is
depressed (upward position).
There are two methods of operation to drive nails with this Nailer.
They are:
1. Intermittent operation (Trigger fire):
2. Continuous operation (Push lever fire):
(1) Intermittent operation (Trigger fire)
1 Position the nail outlet on the workpiece
with finger off the trigger.
2 Depress the push lever firmly until it is
completely depressed.
3 Pull the trigger to drive a nail.
4 Remove finger from the trigger.
To drive another nail, move the Nailer along
the workpiece and repeat this procedure.
(2) Continuous operation (Push lever fire)
1 Pull the trigger with the Nailer off the
workpiece.
2 Depress the push lever against the
workpiece to drive a nail.
3 Move the Nailer along the workpiece with
a bouncing motion.

WARNING
䢇 Keep your finger off the trigger except during fastening
operation, beacuse serious injury could result if the push lever
accidentally contacts you or others in work area.
䢇 Keep hands and body away from the discharge area. The
Stapler with contact trip mechanism may bounce from the
recoil of driving a fastener and unwanted subsequent fastener
may be driven, possibly causing injury.
䢇 Some types of loaded staples can spark out of the muzzle
during a nail driving operation. Exercise caution!
THE OPTIONAL SEQUENTIAL TRIP MECHANISM (SINGLE SHOT PARTS) is for use where
precision fastener placement is desired and must be operated in accordance with the
following “Method of Operation”.
18
English
You must first depress the push lever (upward position) where you want to drive a staple
and then pull the trigger. After the each staple is driven, completely release the trigger and
lift the tool off the work surface. An OPTIONAL SEQUENTIAL TRIP MECHANISM may reduce
the possibility of bodily injury to you or others in the work area. This is because it is less
likely to drive an unwanted staple if you keep the trigger pulled and accidentally bump the
push lever against yourself or others. An OPTIONAL SEQUENTIAL TRIP MECHANISM may
also reduce the speed of operation compared to the standard contact trip mechanism.
NOTE:
䢇 Both STANDARD CONTACT TRIP MECHANISM and OPTIONAL SEQUENTIAL TRIP
MECHANISM are safe if used as described above and accroding to all warnings and
instructions.
䢇 Always handle nails and package carefully. If nails are dropped, collating bond may be
broken.
䢇 After nailing:
1) disconnect air hose from the Nailer;
2) remove all nails from the Nailer;
3) supply 2 – 3 drops of Hitachi pneumatic tool lubricant into the air plug on the Nailer; and
4) open the petcock on the air compressor tank to drain any moisture.

To assure that each nail penetrates to the same depth, be sure that:
1) the air pressure to the Nailer remains constant (regulator is installed and working
properly), and
2) the Nailer is always held firmly against the workpiece.
If nails are driven too deep or shallow into the workpiece, adjust the nailing in the following
order.
1 DISCONNECT AIR HOSE FROM NAILER.
2 If nails are driven too deep, turn the adjuster
to the shallow side.
Adjustments are in half-turn increments.
