Construction

This

is

an

electric

tool

of

Class

II

with

protective

insulation

without

earth

wire

and

in

accordance

with

VDE

re

gulations

0740.

The

p

ro

tective

insulation

is

addi-

tional

to

the

normal

insulation

and

is

attained

by

the

shockproof

moto

and

by

The

drill

is

tested

wit

To

prevent

no

additional

We

recommend

the

use

of

FEIN DSc 736 Operating instructions

Brand: FEIN

Model: DSc 736

Type: Operating instructions

FEIN DSc 736 is a two-speed percussion drill designed for drilling in steel and stone. It features a protective insulation, making it suitable for use without an earth wire. The tool comes with a two-core cable and must not be earthed. With a net weight of 4.9 lbs (2.2 kg), it's easy to handle, and the double insulation and radio suppression ensure safe operation. The percussion mechanism can be adjusted by turning the sleeve clockwise, allowing you to customize the strength of the blow.
