from materials containing stone, paint solvents, wood
preservatives, antifouling paints for vessels, can trigger
allergic reactions to the operator or bystanders and/or
lead to respiratory infections, cancer, birth defects or
other reproductive harm. The risk from inhaling dusts
depends on the exposition. Use dust extraction matched
appropriately for the developing dust, as well as personal
protective equipment and provide for good ventilation of
the workplace. Leave the processing of asbestos-contain-
ing materials to specialists.
Wood and light-metal dust, hot mixtures of grinding dust
and chemical materials can self-ignite under unfavourable
conditions or cause an explosion. Avoid sparking in the
direction of the dust collector as well as overheating of
the power tool and the materials being sanded, empty the
dust collector/container in time, observe the material
manufacturer's working instructions, as well as the rele-
vant regulations in your country for the materials being
worked.

(see Assembly instructions) or on a work bench with fit-
ting bolts (19).
Fasten the sub base or the work bench to the floor using
suitable dowel/bolt connections.

tilt over or the machine to loosen from the sub base or
work bench during operation, and lead to serious acci-
dents.
Electrical connection.
The electrical connection, which is to be provided
by customer, must be carried out by a qualified
electrician.
Observe mains voltage: The mains voltage and the fre-
quency of the power source must agree with the data
onthe type plate of the machine.
Before starting operation for the first time, check the
rotation direction of the motor. The rotation direction
may be changed only by a qualified electrician.

rest to the required height, depending on the size of the
workpiece.
Retighten the adjustment screws (7).
Adjusting the gap clearance (figure 1).
Brushes, grinding or polishing tools are subject to
normal wear. Therefore, the gap clearance must be
checked regularly and corrected if required.
Turn handle screw (8) until the clearance between brush,
grinding or polishing tool (5) and grinding rest (6) is max-
imum 5/64 in.
