CAUTION

⅜ To prevent unintentional operation, never touch the

trigger or place the top end of the push lever on a

work bench on floor. Also, never face the nail outlet

toward any part of a person.

HOW TO USE THE NAILER

CAUTION

⅜ Never use the top cover or housing of this device as a

hammer.

⅜ Take precautions to ensure the safety of persons in

the vicinity during operation.

⅜ Squeeze the trigger when drive a nail, otherwise the

piston can not return correctly.

⅜ Make sure the nailing depth when the temperature is

above 40°C or below 0°C.

1. Nailing procedures

This power tool is equipped with a FULL SEQUENTIAL

ACTUATION MECHANISM.

(1) Intermittent nailing

Depress the nail outlet onto the desired point; then pull

the trigger to drive a nail in a single shot (See Fig. 14).

After nailing once, nailing will not be possible again

until the trigger is released and pressed again.

(2) Push lever

When depressing the nail outlet, be sure to fully lift

the push lever (See Fig. 14) to release the safety lock.

Thus, nails cannot be driven without releasing the

safety lock even though the trigger is pulled.

The machine employs a preventive mechanism for

unloaded operation.

The machine enters a state where the push lever

cannot be pushed up. This takes place when the

magazine is not loaded with nails or when the

remaining number of nails becomes less than 8 or 9

(NR90GC2), 5 or 6 (NR90GR2).

CAUTION

⅜ Exercise care when nailing corners of lumber. When

continuous nailing corners of lumber, a nail may go

astray or break through the corner.

⅜ Do not drive a nail on another nail.

⅜ Do not drive a nail on metal parts.

⅜ Use caution not to throw the push lever tip onto wood

when the push lever cannot be pushed up.

NOTE

⅜ Under low temperature conditions, the tool

sometimes does not operate correctly. Always operate

the tool at the appropriate ambient temperature.

2. Adjusting the nailing depth (See Fig. 16, 17)

To assure that each nail penetrates to the same depth,

be sure that the tool 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 Remove the fuel cell and the battery from the tool

(See Fig. 15).

2 If nails are driven too deep, move the push lever

to forward (See Fig. 16).

If nails are driven too shallow, move the push lever

to backward (See Fig. 17).

3 Stop moving the push lever when a suitable

position is reached for a nailing test.

4 Connect the fuel cell and the battery to the tool.

ALWAYS WEAR EYE PROTECTOR.

Perform a nailing test.

5 Remove the fuel cell and the battery from the tool.

6 Choose a suitable position for the push lever.

3. Clearing a jam

If nails are jammed in firing head, remove it, and adjust

the nailing in the following order.

1 Remove the fuel cell and the battery from the

Nailer. (See Fig. 15)

2 Lock follower back in magazine and remove

fasteners.

3 Remove the bolts with wrench. (See Fig. 18)

4 Pull magazine away from the firing head, and clear

jam. (See Fig. 19)

5 Connect the fuel cell and the battery to the Nailer.

ALWAYS WEAR SAFETY GLASSES.

INSPECTION AND MAINTENANCE

CAUTION

Be sure to remove the battery and fuel cell during

clearing jams, inspection, maintenance and cleaning.

1. Inspecting the magazine

1 DISCONNECT BATTERY and FUEL CELL.

2 Clean the magazine. Remove paper chips or wooden

chips which may have accumulated in the magazine.

Lubricate it with Hitachi gas strip nailer lubricant.

2. Check on mounting screws for each part

At regular intervals check every part for loose mounting

screws. 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 (See page 9)

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 tool in a warm area.

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

and dry place.

Keep out of reach of children.

5. Service parts list

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.

MODIFICATIONS
