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 (figures 1–3).
Belt grinder GX75.
Before any work on the machine itself, pull the
mains plug.
Dismount the spark guard (3).
Dismount the grinding rest (5), the chip/grinding-dust
box (6) and the star-knob bolt (4).
Open side cover (8).
Loosen the tensioning device (1) and remove the grind-
ing belt.
Shut the side cover.
Loosen the lever of tilting device (7) and set the belt
grinder to a horizontal position.
Cylindrical grinding device GXC(figure 2).
Remove the unit from its packaging and fit the accesso-
ries as described in the data sheet.
Position the cylindrical grinding device against the belt
grinder and align the drill holes (33).
Connect both machines with the two levers as well as
the screws with wing nuts (9).
Lightly tilt the device toward the front.
Tighten the levers of the tilting device (7).
Loosen the four star-knob bolts (10) below basin (14)
and align the bottom part of the cylindrical grinding
device at the floor.
Tighten the four star-knob bolts (10) below basin (14)
again.
The power cable must be connected by a quali-
fied electrician to the connection point in the
switch of the belt grinder GX75 according to the
wiring diagram (see Appendix).
Coolant unit GXW (figures 3+4).
Position the tank on the base plate of the cylindrical
grinding device.
Fill approx. 10–15 liters of coolant into the coolant
tank.
Place the lid with the pump unit onto the tank and
mount the drain hose (31) to the connection sleeve of
the tank (14).
Mount coolant hose (27) on the cylindrical grinding
device with magnetic holder (29) in the threaded hole
(34).
The coolant hose must be mounted in such a
manner that the brake wheel or workpiece can-
not catch hold of it.
Plug the plug of the coolant unit into socket outlet (21).
Mounting/replacing the grinding belt
Before any work on the machine itself, pull the
mains plug.
Loosen the tensioning device (1) and mount a
75 x 2000 mm long grinding belt.
The running-direction marking of the grinding
belt must correspond with the rotation direction.
Tension the grinding belt with the tensioning device (1).
