Only

operate the hydraulic breaker from the

Clout

to

avoid injury from flying

Wear ear

PROPER

WAY OF

OP

E

RA

T

I

ON

1.

PROPER

T

H

RU

S

T

To break effectively, a proper

thrust

must be applied

to the

breaker. If

thrust

is

insufficient, the hammering

energy of

the

piston is

not

efficient for breaking

ro

ck

s.

Hammering

force is

then transferred to the

breaker body, arm and boom of

the

ba

se

machine which results in damage of

the

pa

rt

s.

However, if thrust is excessive or breaking is

performed

with

the

boom of the base

m

a

ch

i

n

e

raised, the machine may suddenly

tilt

toward the

movement,

rocks are broken, and

the b

r

e

a

ke

r

body may

hit

against rocks resulting in

d

a

ma

g

e

.

If

hammering

is

performed

under such conditions,

vibrations

may occur in

the tracks

whi

ch

should be avoided

to

ensure no damage

to the

Do

not

hammer without

proper applied

hrust

T

Apply pressure in a

straight

line with

the tool

placed on a rock with

the hammering

side as

vertical as possible. If

the hammering

side is

at

an angle, the

tool

may slip during

and cause

the

chisel and piston

to

be broken or destroyed. When breaking, select the

point

PRECASEION FOR

The

operator

should pay

attention to the

following during

2-10-1. Stop

the operation

as soon as

the

hoses

vibrate

excessively.

Check

to

see if

the

high- and low-pressure hoses of

the

breaker

vibrate

excessively. If so,

t

he

accumulator

may be defective. Contact

the

service

department with

your dealer in your

t

ory

for repair. Further check oil leakage

at the

hose

fitting

points, if oil oozes,

re-tighten the hose

fittings.

Visually inspect

to

see if

there

is a surplus of

tool,

during

operation

as

illustrated

(See

below). If

not, the tool

must be seized in

the front

head. Disassemble
