Check the rotation direction of the motor before starting
the operation of the machine for the first time. If the rota-
tion direction of the motor is incorrect, the workpiece
can be thrown from the machine and cause an accident.
The rotation direction may be changed only by a quali-
fiedelectrician.
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 mate-
rial is removed, dusts develop that can be hazardous 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 particles
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.

Adjustments.
Before any work on the machine itself, pull the
mains plug.
Adjusting the steering bar (figure 3).
Loosen the four screws (1) and adjust the steering bar (2)
to the desired working height. Tighten all screws in this
position.
Adjusting the removal rate (figures 1/4).
Adjust the belt grinder to the approximate working
height with star-knob bolt (3).
Adjust the clearance between grinding belt and surface
with the crank (4). The removal rate can also be adjusted
during the working procedure.
Adjusting the depth stop (figures 1/5).
Loosen screw (5).
Adjust the belt grinder to the maximum desired removal
rate with the crank (4).
Lock the depth stop in this position with screw (5).
Adjusting the height stop (figure 6).
Pivot the steering bar upward, so that the belt grinder
moves upward.
The desired pivoting height can be set with screw (6).
Adjusting the stroke force (figure 7).
The required stroke force can be set with the crank (7).
Adjust the stroke force in such a manner that the belt
grinder can be easily lowered and is automatically held in
the upper position when raising it or during work breaks.
Adjusting the parallelism (figure 8).
For uniform removal rate, it is required that the grinding
belt runs parallel to the surface.
Adjust the belt tracking with star-knob bolt (8).
Adjusting the spark guard (9) (figure 1).
Loosen both wing bolts (10) and adjust the spark guard
(9) in such a manner that the grinding belt is covered off
as far as possible.
Retighten the wing bolts again.
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 (11) until centred.
