Rotating the Main Handle
f
Before any work on the machine itself, pull
the mains plug.
The main handle
23
can be rotated with respect to the
machine housing toward the left or right in steps of
90°. In this manner, the On/Off switch can be brought
into a more convenient position for special working
situations, e.g., for cutting operations using the cut-
ting guide with dust extraction protection guard
20
or
for left-handed persons.
Press the handle unlocking button
24
in the direction
of the arrow and at the same time turn the main handle
23
to the requested position until it latches.
Dust/Chip Extraction
f
Dusts from materials such as lead-containing coat-
ings, some wood types, minerals and metal can be
harmful to one’s health. Touching or breathing-in
the dusts can cause allergic reactions and/or lead
to respiratory infections of the user or bystanders.
Certain dusts, such as oak or beech dust, are con-
sidered as carcinogenic, especially in connection
with wood-treatment additives (chromate, wood
preservative). Materials containing asbestos may
only be worked by specialists.
– Use dust extraction whenever possible.
– Provide for good ventilation of the working
place.
– It is recommended to wear a P2 filter-class res-
pirator.
Observe the relevant regulations in your country
for the materials to be worked.
Operation
Starting Operation
f
Observe correct mains voltage! The voltage
of the power source must agree with the
voltage specified on the nameplate of the
machine. Power tools marked with 230 V can
also be operated with 220 V.
When operating the machine with power from mobile
generators that do not have sufficient reserve capacity
or are not equipped with suitable voltage control with
starting current amplification, loss of performance or
untypical behavior can occur upon switching on.
Please observe the suitability of the power generator
being used, particularly with regard to the mains volt-
age and frequency.
Switching On and Off
To
start
the power tool, press the On/Off switch
2
forward and then down.
To
lock-on
the pressed On/Off switch
2
, push the
On/Off switch
2
further forward.
To
switch off
the power tool, release the On/Off
switch
2
, or when it is locked, briefly press the On/Off
switch
2
and then release it.
Switch Version without Lock-on (country-spe-
cific):
To
start
the power tool, press the On/Off switch
2
forward and then down.
To switch off the machine,
release
the On/Off switch
2
.
f
Check grinding tools before using. The
grinding tool must be mounted properly and
be able to move freely. Carry out a test run
for at least one minute with no load. Do not
use damaged, out-of-centre or vibrating
grinding tools.
Damaged grinding tools can
burst and cause injuries.
Run-on Brake (WKS 230 SE)
When switching off or when the power supply is inter-
rupted, the machine comes to a complete stop within
a few seconds. This means a reduction of the run-on
time of approx. 70 % when compared with angle
grinders without run-on brake, which allows for the
power tool to be placed down sooner.
Note:
When the braking effect decreases noticeably,
the run-on brake has failed. The power tool should be
sent immediately to an after-sales service.
