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. Exericise
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 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 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 plastic 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.
ADJUSTING THE NAILING DEPTH
To assure that each nail penetrates to the same depth, be
sure that :
1) the air pressure to the Nailer remains constant
(requlator 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.
