This Hitachi nailer is equipped with a nailer operation switching device. Use SINGLE SEQUENTIAL ACTUATION MECHANISM or CONTACT ACTUATION MECHANISM in accordance with the work to be performed.

Explanation of the various nailing operations

○

SINGLE SEQUENTIAL ACTUATION MECHANISM:

First, press the push lever against the wood; next, pull the trigger to drive the nail.

After nailing once, nailing will not be possible again

until the trigger is released and pressed again.

○

CONTACT ACTUATION MECHANISM: First, press

the push lever against the wood; next, pull the trigger to drive the nail.

First, pull the trigger; next, press the push lever

against the wood to drive the nail.

If the trigger is held back, a nail will be driven each

time the push lever is pressed against the wood.

METHODS OF OPERATION

This Nailer is equipped with the push lever and does not operate unless the push lever is depressed (upward position). There are two methods of operation to drive nails with this Nailer.

They are:

1. Intermittent operation (Trigger ﬁ re):

2. Continuous operation (Push lever ﬁ re):

English

(1) Intermittent operation (Trigger ﬁ re) Use the SINGLE SEQUENTIAL ACTUATION

MECHANISM setting.

WARNING

●

For intermittent operation, set the switching

device to the leftward position completely. (i.e. Set to SINGLE SEQUENTIAL ACTUATION MECHANISM.)

●

To avoid double ﬁ ring or accidental ﬁ ring due

to recoil.

1) Set the switching device to SINGLE SEQUENTIAL ACTUATION MECHANISM.

2) Pull the trigger rapidly and ﬁ rmly.

Set the switching device to the leftward position

(to set to SINGLE SEQUENTIAL ACTUATION MECHANISM).

(Set the switching device to the leftward position

completely as shown in the diagram. Otherwise, it will be set to CONTACT ACTUATION MECHANISM.)

Position the nail outlet on the workpiece with

ﬁ nger oﬀ the trigger.

Depress the push lever ﬁ rmly until it is completely

depressed.

Pull the trigger to drive a nail.

Remove ﬁ nger from the trigger. To continue nailing in a separate location, move the nailer along the wood, repeating steps

– 5 as required.

WARNING

●

A nail will ﬁ re each time the trigger is

depressed as long as the push lever remains depressed.

(2) Continuous operation (Push lever ﬁ re) Using CONTACT ACTUATION MECHANISM

WARNING

●

To avoid double ﬁ ring or accidental ﬁ ring due

to recoil.

1) Do not press the nailer against the wood with excessive force.

2) Separate the nailer from the wood as it recoils after nailing.

Set the switching device to the rightward position

(to set to CONTACT ACTUATION MECHANISM).

(Set the switching device to the rightward position

completely as shown in the diagram. Otherwise, it will not operate properly.)

Pull the trigger with the Nailer oﬀ the workpiece.

Depress the push lever against the workpiece to

drive a nail.

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 ﬁ nger from the trigger.

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.

DISCONNECT AIR HOSE FROM NAILER

Adjuster

Deep

If nails are driven too deep, turn the adjuster to the

shallow side.

Adjustments are in half-turn increments.

Too Deep

If nails are driven too shallow, turn the adjuster to the

deep side.

Too Shallow

Stop turning the adjuster when a suitable position is

reached for a nailing test.

Connect the air hose. ALWAYS WEAR EYE PROTECTION. Perform a nailing test.

DISCONNECT AIR HOSE FROM NAILER.

Choose a suitable position for the adjuster.
