 WARNING
● 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 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.
ADJUSTING THE NAILING DEPTH
 WARNING
● Disconnect the air hose from the nailer 
before turning the adjuster.
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 fi rmly against the workpiece.
If nails are driven too deep or shallow into the workpiece, 
adjust the nailing in the following order.
