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 1).
Place the machine on the floor with the top side
facing down and mount the sub base according to
the figure and the data sheet.
Fasten the sub base to the floor using suitable
dowel/bolt connections. The connections must
withstand the forces that arise during working.
Faulty assembly can cause the machine to tip over dur-
ing operation and lead to serious accidents.
Because of the risk of accidents, this work must be
carried out by persons who are physically able to
lift the high machine weight.
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 9).
Loosen both clamping levers (1). Set the machine to the
required working height.
Tighten both clamping levers (1) again.
Adjusting the grinding rest (10)(figure 4).
Loosen star-knob bolt (12) and adjust the gap size to 2
mm (max.).
Tighten the star-knob bolt again.
Adjusting the support surface for plane grinding
(20).
For plane grinding, the support surface for plane grind-
ing (20) must be aligned parallel to the grinding belt and
face against it over the complete surface.
Loosen screw (22) and fold down the side cover (23).
Loosen the screws (13) and align the support surface
for plane grinding (20).
Tighten screws (13) again.
Shut the side cover (23) and tighten screw (22) again.
Adjust the gap clearance at the stop (7) to max.
2 mm; for this, loosen screws (26), adjust the
stop (7) and tighten the screws (26) again.
(figure 5)
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 starknob bolt (14) until centred.
If the belt tracking cannot be adjusted centred:
Clean the drive wheel (21) and the contact wheel (19)
with compressed air.
Check the drive wheel and the contact wheel for wear,
deformation and damage. Have damaged components
replaced without delay!
