Intended use of the machine.
The machine is intended for stationary grinding of metal
materials using manufacturer approved grinding belts.

Mounting instructions.

Fasten the machine onto the GRIT GIXS or GIXBE
undercarriage (see mounting instructions). The fastening
of both the undercarriage to the floor and the machine to
the undercarriage must be suitable to withstand the
forces occurring during working.
Use appropriate screw connections (size, length) for
mounting.

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 on
the 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 power
plug from the socket outlet.
Adjusting the spark guard (7).
➤ Loosen both wing bolts (6) and adjust the spark
guard (7) in such a manner that the grinding belt is
covered as far as possible.
➤ Tighten both wing bolts again.
Adjusting the grinding rest (8) (Figure 1).
➤ Loosen star-knob bolt (9) and adjust the gap size to
2 mm (max.).
➤ Tighten the star-knob bolt again.
Adjusting the face- grinding rest (16).
For face grinding applications, the face- grinding rest (16)
must be aligned parallel to the grinding belt and must
touch it over the complete surface.
➤ Loosen the screws (4)/(10) and remove the top and
the front protective cover.
➤ Loosen screw (19) and fold the side cover (18)
down.
➤ Loosen the screws (3) and adjust the gap size
between the stop (5) and the face-grinding rest (16).
The gap size must not exceed 2 mm (max.)!
(Figure 2)
➤ Tighten screws (3) again.
➤ Shut the side cover (18) and tighten screw (19)
again.
➤ Reattach the top and the front protective cover and
tighten the screws (4)/(10) again.
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 (1) until centred.
If the belt tracking cannot be adjusted centred:
➤ Clean the drive wheel (17) and the contact
wheel (15) with compressed air.
➤ Check the drive wheel and the contact wheel for
wear, deformation and damage. Have damaged com-
ponents replaced without delay!

Changing the grinding belt.

Before any work on the machine itself, pull the power
plug from the socket outlet.
➤ Loosen the screws (4)/(10) and remove the top and
the front protective cover.
➤ Loosen screw (19) and fold the side cover (18)
down.
Push belt tension lever (11) up to
release the clamping device.
➤ Remove the old grinding belt.
Before attaching the new grinding belt, observe the infor-
mation concerning the running direction on the inner
side of the grinding belt! It must correspond with the
running direction of the drive wheel.
➤ Place the grinding belt both around the drive
wheel (17) and around the contact wheel (15).
Push the belt tension lever (11) down
again to tension the grinding belt.
