Intended use of the machine.
The radius grinding module GXR is to be used together
with the belt grinder GX75/GX752H exclusively for
grinding off pipe ends with diameters between 16–
75 mm using the application tools and accessories rec-
ommended by FEIN in weather-protected environ-
ments.
Workpieces with diameters below 35 mm may
not be worked with the belt grinder GX75!
Special safety instructions.
Wear personal protective equipment. Depending on
application, use face shield, safety goggles or safety
glasses. Where appropriate, wear dust mask, hearing
protectors, gloves and workshop apron capable of stop-
ping small abrasive or workpiece fragments. The eye
protection must be capable of stopping flying debris
generated by various operations. The dust mask or res-
pirator must be capable of filtrating particles generated
by your operation. Prolonged exposure to high inten-
sity noise may cause hearing loss.
Before switching on, make sure that all clamping levers
and tensioning devices are well tightened. If the
machine suddenly sinks or the workpiece comes loose
during the working procedure, this can lead to serious
accidents.

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.
Radius grinding module GXR.
Remove the unit from its packaging and fit the accesso-
ries as described in the data sheet.
Position the radius grinding module against the belt
grinder and align the drill holes of the screws.
Connect both units (13) with the two mounting levers.
Tighten the levers of the tilting device (7).
Fill the collection box (18) half full with water. Position
the collection box between the support columns of the
radius grinding module.
There is a fire hazard when operating the
machine without the collection box filled with
water!
Mounting the contact roller.
Before any work on the machine itself, pull the
mains plug.
Loosen both wing bolts (11) and completely slide the
spark guard (10) up.
Insert a contact roller (21) with the desired diameter
into the guide fork and secure it with both screws (20).
Adjust the belt tracking each time after changing a con-
tact roller.
Contact rollers not in use should always be protected
against damage by placing them in the bracket/magazine
for contact rollers (27).
Mounting/replacing the grinding belt
Before any work on the machine itself, pull the
mains plug.
Open side cover (8+19).
Loosen the tensioning device (1) and mount a
75 x 2250 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).
Move the grinding belt manually and observe, if it
moves off towards the left or right of the contact roller.
Adjust the guidance of the drive wheel on the belt
grinder such that the grinding belt runs centrally. The
exact calibration is carried out while the machine is run-
ning.
