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.

Assembly instructions (figure 6).
Fasten the machine on the Fein sub base GIXS or GIXBE
(see Assembly instructions) or on a work bench with fit-
ting bolts (22).
Fasten the sub base or the work bench to the floor using
suitable dowel/bolt connections.
All connections must withstand the forces that arise dur-
ing 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 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.
Adjustments.
Before any work on the machine itself, pull the
mains plug.
Adjusting the spark guard (7).
Loosen both wing bolts (6) and adjust the spark guard (7)
in such a manner that the grinding belt is covered off as
far as possible.
Tighten both wing bolts again.
Adjusting the grinding rest (8) (figure 1).
Loosen star-knob bolt (9) and adjust the gap size to 2 mm
(max.).
Tighten the star-knob bolt again.
Adjusting the support surface for plane grinding
(16).
For plane grinding, the support surface for plane grinding
(16) must be aligned parallel to the grinding belt and face
against it over the complete surface.
Loosen screws (4)/(10) and remove the top and front
safety covers.
Loosen screw (19) and fold down the side cover (18).
Loosen screws (3) and adjust the gap clearance between
the stop (5) and the support surface for plane grinding
(16). The gap clearance may not exceed 2 mm max.!
(figure 2)
Tighten screws (3) again.
Shut the side cover (18) and tighten screw (19) again.
Mount the top and front safety covers again and retighten
screws (4)/(10).
Adjusting the belt tracking.
Switch the machine on only briefly
and check the belt tracking.
If the grinding belt moves left or right,
adjust the belt tracking with the star-
knob bolt (1) until centred.
If the belt tracking cannot be adjusted centred:
Clean the drive wheel (17) and the contact wheel (15)
with compressed air.
Check the drive wheel and the contact wheel for wear,
deformation and damage. Have damaged components
replaced without delay!
Replacing the grinding belt.
Before any work on the machine itself, pull the
mains plug.
Loosen screws (4)/(10) and remove the top and front
safety covers.
Loosen screw (19) and fold down the side cover (18).
Tilt lever (11) upward to release the
tensioning device.
Remove the old grinding belt.
Before mounting the new grinding
belt, observe the running-direction
indication on the rear of the grinding
belt! It mus correspond with the rotation direction of the
drive wheel.
Place the grinding belt both around the drive wheel (17)
and around the contact wheel (15).
