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.

Assembly instructions (figure 1).
Place the machine on the floor with the top side fac-
ing 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 during
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 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 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 grinding
(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 star-
knob 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!
