Application

The

full

tightening

or

slackening

action

provided

depends

on

the

time

during

which

the

percussion

mechanism

is

allowed

to

run.

Max.

tightening

torque

is

the

sum

of

the

torque

applied

by

each

stroke.

1

According

to

the

type

of

screwed

connection

the

max

.

torque

will

generally

represent

approx.

100

single

torque

strok-

es,

which

are

applied

in

5

seconds.

Available

max.

torque

in

normal

service

is

500

lbs.

ft

(70

mkg)

(see

diagram).

There

is

no

point

in

applying

the

tool

for

longer

than

5

seconds

since

the

torque

will

not

increase

any

further,

while

the

tool

head

will

appreciably

heat

.

Overheating

will

lead

to

increased

wea

r

of

all

percussion

components

and

excessive

lubricant

consumption.

6.

Maintenance

and

Lubrication

This

will

depend

on

the

duty.

The

following

instructions

are

for

continuous

use

in

8-hour

day

with

actual

tool

running

time

representing

20°

/o

of

total

duty

period.

Grease

once

per

week

at

the

lubricating

nipple

(58)

.

Percussion

mechanism

and

gearing

should

be

com

pletely

cleaned

of

old

grease

at

least

every

400

duty

hours

(approx.

8

weeks).

For

this

purpos

e

unscrew

four

screws

(64).

remove

outer

bear-

ing

(57)

and

lift

percussion

mechanism

out

of

intermediate

bear-

ing

without

dismantling

it.

Then

apply

plenty

of

grease

Sst

1

to

the

impact

faces

of

parts

(55)

and

(56),

as

well

as

to

planetary

gearing

(80

g/2

oz).

Reference

for

tube:

MZ

60-3/Sst

1 (90 g/3 oz).

After

900

hours

rinse

ball

bearings

in

clean

solven

t

and

pack

with

fresh

grease

(Sst

1)

.

The

space

between

inner

an

d

outer

rings

is

to

be

one

third

filled

with

grease

in

order

to

prevent

overheating

of

th

e

bearings.

To

avoid

overheating

and

to

ensure

adequate

lubrication

at

the

same

time,

it

is

important

to

pack

the

gearing

with

the

grades

and

quantities

of

grease

listed

in

the

table

below:

No

claims

can

be

entertained

for

damage

due

to

n

eg

ligent

main-

tenance

and

inadequate

lubrication

.

If,

after

long

duty,

the

impact

dogs

of

percussion

piston

(55)

and

tool

holder

(50)

are

worn

th

ey

must

be

reground

so

that

the

mechanisms

should

be

dismantled

according

to

the

instructions.

We

recommend

our

Fein

to

carry

out

all

repair

work

of

this

and

expertly.

Please,
