4. Inspecting the feeders

(1) Occasionally clean the knob sliding part and then

apply the recommended oil (See Fig. 18).

(2) Open the nail guide and remove dust, etc., as shown

in Fig. 19. Apply lubricant to the sliding groove of the

feeder and feeder shaft. Check sub nail stopper slide

smoothly by pushing them with your finger.

(3) Also, apply the recommended oil to the feeding surface

of the nose and nail guide after cleaning. This promotes

smooth operation and retards corrosion.

CAUTION

Check for smooth movement of the feeders and

stoppers before use. If movement is uneven, nails

could be fired at an irregular angle, presenting a

hazard to the operator and others nearby.

5. Inspecting the magazine

Clean the magazine. Remove dust of wooden chips

which may have accumulated in the magazine.

6. 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.

7. Service parts list

C:No. Used

D:Remarks

CAUTION

Repair, modification and inspection of Hitachi Power

Tools must be carried out by an 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.

MODIFICATIONS

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 com-

pressor 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 advisable to

use an oiler filter reducing valve. Please limit the length of

the hose between the nailer and the air set to within 10 m

when using (See Fig. 20).

Noise Information

Noise characteristic values in accordance with Dr prEN

792-13, JUNE, 1997:

The typical A-weighted single-event sound power level

,1s,d = 97 dB

The typical A-weighted single-event emission sound

pressure level at work station

,1s,d = 87 dB

These values are tool-related characteristic values and

do not represent the noise development at the point of

use. Noise development at the point of use will for

example depend on the working environment, the

workpiece, the workpiece support and the number of

driving operations, etc.

Depending on the conditions at the workplace and the

form of the workpiece, individual noise attenuation

measures may need to be carried out, such as placing

workpieces on sound-damping supports, preventing

workpiece vibration by means of clamping or covering,

adjusting to the minimum air pressure required for the

operation involved,etc.

In special cases it is necessary to wear hearing protection

equipment.

Vibration Information

The typical vibration characteristic value in accordance

with Dr prEN 792-13, JUNE,1997 does not exceed 2.5 m/s

This values is a tool-related characteristic value and does

not represent the influence to the hand-arm-system

when using the tool. An influence to the hand-arm-

system when using the tool will for example depend on

the gripping force, the contact pressure force, the working

direction, the adjustment of energy supply, the workpiece,

the workpiece support.
