If

a

non

relieving

coupler

Is

used

on

the

to

drive

a

fastener

even

after

disconnecting.

The

OF

DOUBLE

FIRE

DUE

TO

RECOIL

If

the

push

lever

is

unintentionally

allowed

to

re¬

contact

the

workpiece

following

recoil,

an

unwanted

fastener

will

be

driven.

In

order

to

avoid

this

undesirable

double

fire,

O

Intermittent

operation

(Trigger

firing)

1)

Set

the

switching

device

to

SINGLE

ACTUATION

MECHANISM.

2)

Pull

the

1)

Do

not

press

nailing.

21.

DO

NOT

DRIVE

FASTENERS

INTO

THIN

BOARDS

OR

NEAR

CORNERS

AND

EDGES

OF

WORKPIECE.

The

fasteners

can

be

driven

through

from

the

workpiece

and

hit

someone.

22.

NEVER

DRIVE

FASTENERS

FROM

BOTH

SIDES

OF

A

WALL

AT

THE

SAME

TIME.

The

fasteners

can

be

driven

into

and

through

the

wall

and

hit

a

person

on

the

opposite

side.

23.

CHECK

FOR

LIVE

WIRES.

Avoid

the

risk

of

severe

electrical

shock

by

checking

for

live

electrical

wires

that

may

be

hidden

by

walls,

floors

or

ceilings.

Turn

off

the

breaker

switch

to

ensure

there

are

no

live

wires.

24.

NEVER

CARRY

doing

maintenance

and

inspection;

2)

clearing

a

jam;

3)

it

of

air

that

is

required.

LUBRICATION

It

is

important

that

the

Nailer

be

properly

lubricated.

Without

proper

lubrication,

the

Nailer

will

not

work

properly

and

parts

will

wear

prematurely.

O

Use

Hitachi

pneumatic

tool

lubricant.

Do

not

use

detergent

oil

or

additives.

These

lubricants

will

harm

the

0-rings

and

other

rubber

parts.

This

will

cause

the

Nailer

to

malfunction.

O

Fllter-regulator-lubricator

units

should

always

be

used.

Keep

the

lubricator

filled

with

Hitachi

pneumatic

tool

lubricant.

O

If

a

lubricator

is

not

available,

supply

5-10

drops

of

Hitachi

pneumatic

tool

lubricant

into

the

air

plug

on

the

Nailer

twice

a

day.

COLD

WEATHER

CARE

O

Do

not

store

the

Nailer

in

a

cold

weather

environment.

Keep

the

Nailer

In

a

warm

area

until

beginning

the

work.

O

If

the

Nailer

Is

already

cold,

bring

it

in

a

warm

area

and

allow

the

Nailer

to

warm

up

before

use.

©

Reduce

the

air

pressure

to

64

psl

(4.4

©

Remove

all

nails

from

the

Nailer.

©

Connect

the

air

hose

and

free-fire

(blank-fire)

the

Nailer.

The

lowered

air

pressure

will

be

enough

to

free-

fire

the

Nailer.

Slow

operation

tends

to

warm

up

the

moving
