(2) Continuous operation (Push lever fire)
Using CONTACT ACTUATION MECHANISM
WARNING
To avoid double firing or accidental firing due to
recoil.
1) Do not press the nailer against the wood with
excessive force.
2) Separate the nailer from the wood as it recoils
after nailing.
1 Set the switching device to the downward position
(to set to CONTACT ACTUATION MECHANISM).
(Set the switching device to the downward
position completely as shown in the diagram.
Otherwise, it will not operate properly.)
2 Pull the trigger with the Nailer off the workpiece.
3 Depress the push lever against the workpiece to
drive a nail.
4 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
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. This Hitachi nailer 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. Exercise
caution!
THE FULL SEQUENTIAL ACTUATION MECHANISM
(SEQUENTIAL TRIP MECHANISM) 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 want 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 FULL SEQUENTIAL ACTUATION
MECHANISM (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.
NOTE:
If all warnings and instructions are followed, safe
operation is possible with all three systems: SINGLE
ACTUATION MECHANISM, CONTACT ACTUATION
MECHANISM and FULL SEQUENTIAL ACTUATION
MECHANISM.
Always handle nails and package carefully. If nails are
dropped, collating paper may be broken.
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.
