Construction

This one-speed percussion drill is an electric tool

of

Class

II

with

protective insulation

without

earth

wire

and

in

accordance

with

VDE

regulations 0740. The

protective

insulation is

additional

to the

normal

insulation

and

is

attained

by

the

shockproof

motor

housing

made

of

Polyamide

and

by

insulating

the

armature

shaft

against

the

gearing.

The

drill

is

tested

with

the

prescribed test

voltage

of

4000 V (1500 V

for Class I). The machine

is

radio

suppressed according to radio

inter-

ference degree

N.

It

is

supplied

with

a

two-core

cable

without

earth

wire

and

must

not

be earthed.

Type

ASc 736 for

low

tension (voltage 42 Volts)

is

of

the

same design

but

without

double insulation

and

not

radio

suppressed.

To

prevent

damage

to

the

insulation

no

additional

marking

plates

and

signs

must

be

riveted

or

screwed

on

the

housing.

We recommend the use

of

transfers only.

3.

Connection

and

Operation

Main

voltage must correspond to

the

operating

voltage

marked

on

the

rating

plate.

The

tool can be

plugged

into

plain

or

safety sockets. .

Switch

must

be

in

the

"Off"

position

when

connecting.

4.

Maintenance

The

one-speed percussion drill requires

proper

maintenance

. Before

carrying

out

any

maintenance

work

always remember

to

pull

out

the

plug.

Every

300

duty

hours clean the machine

of

carbon

dust

and

dirt,

in

particular

commutator

and

insulated parts. This

is

done

with

a

brush

or

by

blowing

out

the

tool

with

dry

pneumatic

air.

After

checking

the

carbon brushes

make

sure

to

refit

them

in

their

original

position

and

check

that

they

move

easily

in

their

holder.

They

should

be replaced

at

the latest

when

they

have

worn

down

to

7

mm

(1/4").

Please,

only

use original Fein carbon brushes.

After

fitting

new

brushes

run

tool

unloaded

for about

15

minutes

to

allow

brushes

to

bed

in.

One

pair

of

spare carbon brushes will be

found

in

the

cover

of

the

handle, please, do

not

forget

to

reorder

them

in

time.

In

order

to

prevent

accidents

check

cable

at

regular

intervals.

To

re-

place

the

cable take off the screws (24, 25),

then

take

off the

handle

cover

(20), loosen

the

two

screws (19)

of

the

terminal

clamp

(18)

and

clamp off the cable from the switch (2).
