Conn

e

ction

and

operation

Main

voltage

must

correspond

to

the

operating

voltage

marked

on

the

rating

plate.

To

prevent

the

overbridging

of

the

insulation

no

additional

marking

plates

and

signs

must

be

riveted

or

screwed

on

the

housing.

We

recommend

the

use

of

transfers

only.

The

machine

is

provided

with

a

reversing

switch

for

clockwise

and

anticlockwise

rotation.

It

must

not

be

operated

when

the

machine

is

running

.

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

.

According

to

the

type

of

screwed

connection

the

max

.

torque

will

be

generally

reached

in

3

or

5

seconds

.

The

running-down

torques

may

vary

considerably

with

thread

friction,

friction

between

bolt

head

and

rest

face,

flexibility

("spring")

in

the

parts

to

be

joined

,

wear

in

the

tool

drives

and

socket

squares.

when

they

have

worn

down

to

7

mm

(0.28 in.).

To

replace

brushes

see

paragraph

4.

Only

use

Fein

carbon

brushes.

After

No

claims

can

be

entertained

for

Dismantling

The

tool

should

only

be

taken

apart

by

an

expert.

1.

Loosen

screws

(51, 31).

remove

handle

cover

(46).

2.

Unscrew

the

cable

clamping

bridge

(49).

take

off

all

cables

from

switch

(47).

3.

Lodsen

screws

(31, 39).

draw

to

the

bottom

the

lower

handle

part

(45)

and

the

cover

plate

(38).

till

the

screw

is

loosened

(15). .

4.

Unscrew

screws

(14)

and

take

out

the

cover

(13).

5.

Unscrew

the

cable

of

the

carbon

brushes

(6)

and

draw

out

of

the

holder

the

carbon

brushes

(5).

6.

Unscrew

the

screws

(33)

and

take

carefully

out

the

cover

of

th

e

housing

(52).

the

switch

(19)

remains

hanging

to

the

cover

of

the

housing.

7.

Unscrew

screws

(30)

and

take

off

the

outer

bearing

(59).

the

gear

rim

(62).

the

tool-holder

(78).

8.

Unscrew

screws

(29)

of

the

motor

housing,

draw

armature

(21)

with

fan

(24)

and

ball

bearing

(36)

out

of

the

inter-

mediate

bearing

(61)

.

9.

Remove

the

driving

shaft

(63-77)

at

the

percussion

piston

(76)

with

light

axial

strokes

out

of

the

intermediate

bearing

(61).

10.

The

parts

of

the

percussion

mechanism

are

made

of

high-

quality

steel,

so

that

they

do

not

wear

considerably

during

normal

duty.

Should

disassembling

prove

necessary

after

a

long

period

of

application,

it

will

be

easily

carried

out.

Fix

the

percussion

mechanism

at

the

drive

assembly

vertically

in

the

vice.

Then

the

"Seeger"

circlip

may

be

taken

out

of

the

drive

assembly

by

means

of

a

pair

of

angle

pincers

(Seeger-Order-Reference

J 31).

The

compression

spring

(75)

relaxes

and

draws

out

the

ball

pivot

(72)

together

with

the

lower

retaining

ring

(73)

.

Remove

the

percussion

piston

(76).

the

intermediate

shaft

(71)

and

the

compression

ring

(70)

·

upwards.

Attention:

The

race

in

the

drive

assembly

must

be

filled

with

19

balls

(69)

of

1/s"

(3

mm)

C/)

.

- - -

--

---------

~

The

percussion

mechanism

may

also

be

taken

apart

by

means

of

a

pair

of

straight

"Seeger"-pincers

(Order-Reference

J

3)

.

When

doing

so,

first

draw

the

intermediate

shaft

(71)

out

of

the

per-

cussion

mechanism.

By

the

spring

tension

the

percussion

piston

is

kept

in

its

centric

position.

Press

the

percussion

piston

side-

wards

as

far

as

necessary

to

remove

the

"Seeger"

circlip

with

a

pair

of

normal

pincers.

When

re-assembling

the

percussion

mechanism

make

sure

that

the

"Seeger"

circlips

fit

completely

in

their

grooves

.

Re-assemble

in

reverse

sequence.

Do

not

forget

the

washers.

Should

you

have

difficulties,

send

the

percussion

mechanism

to

our

Fein

Service

Stations.

5.

Repair

and

spare

parts

We

recommend

our

Fein

Service

stations

to

carry

out

all

over-

haul

and

repair

work

quickly

and

expertly

.

Please,

quote

Order

Reference

when

ordering

spare

parts

or

send

stating

the

We

draw

your

attention

to

the

need

to

carry

out

a

high

voltage

test

in

accordance

with

your

local

regulations

(or

before

taking

a
