English The OPTIONAL SEQUENTIAL TRIP MECHANISM (SINGLE SHOT PARTS) 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 OPTIONAL SEQUENTIAL TRIP MECHANISM may reduse 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. An OPTIONAL SEQUENTIAL TRIP MECHANISM may also reduse the speed of operation compared to the standard contact trip mechanism. NOTE: ⅷ Both STANDARD CONTACT TRIP MECHANISM and OPTIONAL SEQUENTIAL TRIP MECHANISM are safe if used as described above and according to all warnings and instructions. ⅷ Always handle nails and package carefully. If dropped, the collated nails may break or come loose. In such cases, do not use the nails because, if used in that condition, nail feed may become faulty and result in missed nails or jamming of the nails. ⅷ 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 (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 depth in the following order. 1 DISCONNECT AIR HOSE FROM NAILER 2 If nails are driven too deep, turn the adjuster to the shallow side.

English
The OPTIONAL SEQUENTIAL TRIP MECHANISM (SINGLE
SHOT PARTS) 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 OPTIONAL SEQUENTIAL TRIP MECHANISM may
reduse 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. An OPTIONAL SEQUENTIAL TRIP
MECHANISM may also reduse the speed of operation
compared to the standard contact trip mechanism.
NOTE:
±
Both STANDARD CONTACT TRIP MECHANISM and
OPTIONAL SEQUENTIAL TRIP MECHANISM are safe
if used as described above and according to all
warnings and instructions.
±
Always handle nails and package carefully.
If dropped, the collated nails may break or come
loose. In such cases, do not use the nails because, if
used in that condition, nail feed may become faulty
and result in missed nails or jamming of the nails.
±
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
(regulator is installed and working properly), and
2)
the Nailer is always held firmly against the workpiece.
<NV83A2>
If nails are driven too deep or shallow into the workpiece,
adjust the nailing depth 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.
4
Connect the air hose.
ALWAYS WEAR EYE PROTECTION.
Perform a nailing test.
5
DISCONNECT AIR HOSE FROM NAILER.
6
Choose a suitable position for the adjuster.
