The SINGLE SEQUENTIAL ACTUATION MECHANISM is for use where precision fastener
placement is desired.
The SINGLE SEQUENTIAL ACTUATION MECHANISM may reduce the possibility of bodily
injury to you or others in the work area compared to the CONTACT ACTUATION
MECHANISM. 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.
The SINGLE SEQUENTIAL ACTUATION MECHANISM may also reduce the speed of
operation compared to the CONTACT ACTUATION MECHANISM. The SINGLE SEQUENTIAL
ACTUATION MECHANISM is recommended to inexperienced users.
NOTE:
● If all warnings and instructions are followed, safe operation is possible with two systems:
SINGLE SEQUENTIAL ACTUATION MECHANISM, and CONTACT ACTUATION
MECHANISM.
● Always handle nails and package carefully. If nails are dropped, collating bond may be
broken, which will cause mis-feeding and jamming.
● 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
WARNING
● When adjusting the Adjuster, be sure to remove your finger from
the trigger and disconnect the air hose from the nailer.
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.
If nails are driven too shallow, turn the adjuster
to the deep side.
3 Stop turning the adjuster when a suitable
position is reached for a nailing test.
