Adjusting The Nailing Depth - Hitachi NV 90AG Instruction And Safety Manual

English
● Keep your fi nger 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 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 wire 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

● Disconnect the air hose from the nailer
before turning the adjuster.

(regulator is installed and working properly), and
2) the Nailer is always held fi rmly 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
