This Hitachi nailer has a STANDARD CONTACT TRIP
MECHANISM (Bounce Fire). An OPTIONAL SEQUENTIAL
TRIP MECHANISM kit (SINGLE SHOT) is available as order
part number 878226.
THE STANDARD CONTACT TRIP MECHANISM (Bounce
Fire) is for use where rapid fastener placement is desired
and must be operated in accordance with the following
“Methods of Operation”.
NOTE:
䢇 Be careful that the final nail can be dropped or driven
at an irregular angle.
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.
Push lever

Trigger
(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.
Each depression of the push lever will drive a nail.
As soon as the desired number of nails have been
driven, remove finger from the trigger.

WARNING
䢇 Keep your finger off the trigger except during
fastening operation, because 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 nailer 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 nails can spark out of the
muzzle during a nail driving operation. Exericise
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”.
You must first depress the push lever (upward
position) where you wnat to drive a nail and then pull
the trigger. After the each nail 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 nail 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 wire may be damaged
and cut, which will cause mis-feeding and jamming.
䢇 After nailing:
1) disconnect air hose from the Nailer;
2) remove all nails from the Nailer;
3) supply 5 – 10 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.
