Rotating the Machine Head
Before any work on the machine itself, pull the mains
plug.
Completely unscrew the four screws. Rotate the machine
head carefully, without removing it from the housing, to the
new position. Screw in and tighten the four screws again.
Dust/Chip Extraction
Dust from materials such as lead-containing coatings,
some wood types, minerals and metal can be harmful to
one's health. Touching or breathing-in the dust can cause
allergic reactions and/or lead to respiratory infections of
the user or bystanders.
Certain dust, such as oak or beech dust, is considered car-
cinogenic, especially in connection with wood-treatment
additives (chromate, wood preservative). Materials con-
taining asbestos may only be worked by specialists.

Carry out a test run for at least one minute with no load.
Do not use damaged, out-of-centre or vibrating grind-
ing tools. Damaged grinding tools can burst and cause in-

caused by a jammed disc while cutting, the
power supply to the motor is electronically
interrupted.
To restart the operation, switch the
On/Off switch 3 to the Off position and start
the machine again.
