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):

WARNING
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.
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.
Some types of loaded nails can spark out of the
muzzle during a nail driving operation. Exericise
caution!
You must first depress the push lever (upward posi-
tion) 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.
Both STANDARD CONTACT TRIP MECHANISM and
OPTIONAL SEQUENTIAL TRIP MECHANISM are safe if
used as described above and accroding to all warnings
and instructions.
Always handle nails and package carefully. If nails are
dropped, collating plastic may be broken.
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.
