Assembly instructions (figures 1–3).
Belt grinder GI75/GI150.
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 grinding
belt.
Shut the side cover.
Loosen the lever of tilting device (7) and set the belt
grinder to a horizontal position.
Cylindrical grinding device GIC.
Remove the unit from its packaging and fit the accessories
as described in the data sheet.
Position the cylindrical grinding device against the belt
grinder and align the drill holes of the screws (11).
Connect both machines by fastening the two eccentric
clips (9) with the 4 bolts (11) and then tightening with the
eccentric lever (10). Tighten clamping lever (20) as well
as the bolt with the nut.
Connect the power cable at the connecting point of
the switch of the belt grinder GI75/GI150.
Coolant unit GXW (figures 3+4).
Position the tank on the base plate of the cylindrical
grinding device.
Fill approx. 30–35 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
(15).
Mount the coolant hose (27) to the cylindrical grinding
device.
The coolant hose must be mounted in such a man-
ner that the brake wheel or workpiece cannot
catch hold of it.
Plug the plug of the coolant unit into socket outlet (14).
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 2000/150 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).
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 cali-
bration is carried out while the machine is running.
Switch the belt grinder on. Check if the contact pulley
rotates in the direction of the arrow.
Switch the belt grinder off again.
If the contact disc rotates in the opposite direction
of the arrow, the motor's direction of rotation must
be changed by a qualified electrician.
Adjusting the guide rail (figures 3A+5).
Before any work on the machine itself, pull the
mains plug.
Loosen both screws (23) and adjust the clearance of the
guide rail to the brake wheel:
– Pipe diameter 10–12 mm: Adjustment according to
figure "1".
– Pipe diameter 10–130 mm: Adjustment according to
figure "2".
Tighten screws (23) again.
Adjusting the brake wheel (figure 3).
Before any work on the machine itself, pull the
mains plug.
Adjusting the parallelism.
Release clamping lever (20) and adjust the brake wheel
(19) with the handle (16) in such a manner that it runs
parallel to the contact pulley when viewed from above.
This helps to achieve a uniform feed pressure and a uni-
form grinding pattern. The optimal setting must be deter-
mined by practical testing.
