2. Construction
This impact
w
rench
is
an
electric
tool of class
II
in a
ccordance
with
the
VDE
re
gulations
0740.
In addition
to the
n
ormal insula
-
tion
the
tool
is provided w
ith
double
insulation.
The se
cond
insulation
separate
s all
accessible parts of the
metal
ca
sing
from
all
inte
rnal
parts liable to become
live. The
prote ctive insula
-
tion is tested with the
pre
scribed
te
st voltage of 4000
V
(1500 V
for class I)
. The
machine is radio suppressed in accordance with
radio interference
degree
N. It
is
supplied with
a two-core cable
without e
a
rth
w ire a
nd must not b
e
e
a
rthed.
Gearing
and p
e rcussion mecha
nism
are tota lly
en closed in
the
t ool-head
casing
; their construction is w
ell-planned
and clear.
The
tool h older
complies w
ith
in te
rnational
standards
and h
as
a
1"
square
drive
.
The machine
is prov
ided with a reversing switch for
clockwise
and anticlock
w ise
rotation. It must not be operated when the
machine is running.
To prevent the
ove
rbridging of the insulation no additional
ma
rking
plate
s and
signs
must b
e
riveted or screwed on
the
housing. We
re
commend
the
use of transfers
only.

4. Mode of Operation
The motor drive
s
the tool
h older with tool
attached
via g
e
aring
and percussion m echanism.
The
direct
drive
is
cu
t
out
a
s soon
as the
screw
or n
u
t has
b een
roughly
run
down.
Once the motor
reaches its
rated
load,
the
percussion mech
anism comes
into
operation and converts the drive
force of
the motor - which
continues
to run at uniform speed - into an intermittent torque
w
ith
two
strokes for
each rev
olution of
the·
d
riv
e
assembly
.
Screws
and nuts
a re slackene
d in
reverse o rder:
first
pe
rcussion
s trokes, followed by direct drive. The
tool
is
easy
to
h
andle
,
as
the
op
erator needs not
exert
an
y restraining torque
.
As
the
clu
tch will
a
lways disengage as
soon
as the rated
load
is
attain-
ed,
the motor
cannot
be
overload
ed.
