Check the rotation direction of the motor before start-
ing the operation of the machine for the first time. If the
rotation direction of the motor is incorrect, the work-
piece can be thrown from the machine and cause an
accident. The rotation direction may be changed only
by a qualifiedelectrician.
Make sure that you or other persons are not standing
directly next to the grinding belt when switching the
machine on. The grinding belt can tear apart and cause
serious injuries.
Handling hazardous dusts
For work procedures with this power tool where
material is removed, dusts develop that can be hazard-
ous to one's health.
Contact with or inhaling some dust types, e. g. asbestos
and asbestos-containing materials, lead-containing coat-
ings, metal, some wood types, minerals, silicate parti-
cles 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 pro-
vide for good ventilation of the workplace. Leave the
processing of asbestos-containing materials to special-
ists.
Wood and light-metal dust, hot mixtures of grinding
dust and chemical materials can self-ignite under unfa-
vourable 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 instruc-
tions, as well as the relevant regulations in your country
for the materials being worked.

Assembly instructions (figure 7).
Mount the machine on the Fein GIB/GIBE sub base (see
assembly instructions).
Fasten the sub base to the floor using suitable
dowel/bolt connections. The connections must with-
stand the forces that arise during working.
Faulty assembly can cause the sub base or work bench
to tilt over or the machine to loosen from the sub base
or work bench during operation, and lead to serious
accidents.
Electrical connection.
The electrical connection, which is to be pro-
vided by customer, must be carried out by a qual-
ified 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.
Adjustments.
Before any work on the machine itself, pull the
mains plug.
Adjusting the incline (figure 7).
Loosen both clamping levers (28). Set the machine to
the required working height.
Tighten both clamping levers (28) again.
Adjusting the spark guard (5).
Loosen both wing bolts (6) and adjust the spark guard
(5) in such a manner that the grinding belt is covered off
as far as possible.
Tighten both wing bolts again.
Adjusting the grinding rest (7) (figure 1).
Loosen star-knob bolt (11) and adjust the gap size to
2 mm (max.).
Tighten the star-knob bolt again.
Adjusting the stop (4)(figure 2)
Loosen screws (3) and adjust a max. gap clearance of
2 mm.
Tighten screws (3) again.
