(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.

⅜ Under low temperature conditions, the machine

sometimes does not operate correctly. Always operate

the machine at the appropriate ambient temperature.

2. Adjusting the nailing depth (See Fig. 7)

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.

4 Connect the air hose.

ALWAYS WEAR EYE PROTECTOR.

Perform a nailing test.

5 DISCONNECT AIR HOSE FROM NAILER.

6 Choose a suitable position for the adjuster.

3. Using the nose cap (See Fig. 8)

CAUTION

When detaching or attaching the nose cap, be sure

to remove your finger from the trigger and

disconnect the air hose from the nailer.

The nose cap is attached to the push lever tip to protect

the workpiece from scratches or damage. Remove in

the order shown below when not using.

(1) DISCONNECT AIR HOSE FROM NAILER.

(2) Pull out the nose cap in the direction of the arrow as

shown in the diagram.

⅜ Attach to the tip of the push lever in the reverse order

of detaching.

INSPECTION AND MAINTENANCE

CAUTION

Be sure to disconnect the hose during cleaning

jams, inspection, maintenance and cleaning.

1. Inspecting the magazine

1 DISCONNECT AIR HOSE.

2 Clean the magazine. Remove paper chips or wooden

chips which may have accumulated in the magazine.

Lubricate it with Hitachi pneumatic tool lubricant.

2. Check on mounting screws for each part

At regular intervals check every part for loose mounting

screws and whether or not there are any air leaks.

Retighten any loose screws. Operating the equipment

with loose screws untightened will incur a hazard.

3. Inspecting the push lever

Check if the push lever can slide smoothly.

Clean up the sliding area of the push lever and use the

provided oil for lubrication from time to time.

Lubrication enables smooth sliding and simultaneously

serves to prevent the formation of rust.

4. Storing

⅜ When not in use for an extended period, apply a thin

coat of the lubricant to the steel parts to avoid rust.

⅜ Do not store the Nailer in a cold weather environment.

Keep the Nailer in a warm area.

⅜ When not in use, the Nailer should be stored in a warm

and dry place.

Keep out of reach of children.

5. Service parts list

A: Item No.

B: Code No.

C: No. Used

D: Remarks

CAUTION

Repair, modification and inspection of Hitachi Power

Tools must be carried out by a Hitachi Authorized

Service Center.

This Parts List will be helpful if presented with the

tool to the Hitachi Authorized Service Center when

requesting repair or other maintenance.

In the operation and maintenance of power tools, the

safety regulations and standards prescribed in each

country must be observed.

MODIFICATION

Hitachi Power Tools are constantly being improved

and modified to incorporate the latest technological

advancements.

Accordingly, some parts (i.e. code numbers and/or

design) may be changed without prior notice.

COMPRESSOR

CAUTION

When the maximum, operating pressure of the air

compressor exceeds 8.3 bar (120 psi.), be sure to

provide a reducing valve between the air compressor

and nailer. Then, adjust the air pressure within the

operating range of 4.9 – 8.3 bar (70 – 120 psi.). If the

air set is installed, lubrication is also possible, thus

providing additional convenience.

OILER-FILTER-REDUCING VALVE (Air Set)

So that the equipment can be operated under an optimum

condition to ensure extended service life, it is

recommended to use an oiler filter reducing valve. Please

limit the length of the hose between the unit and the air

set to within 10 m when using (See Fig. 9).
