Intended use of the machine.
The machine is intended for stationary sanding/grinding
of metal materials and for use with radius grinding mod-
ule GXR or centerless unit GXC using manufacturer
approved grinding belts.
Mounting instructions.
Assemble the undercarriage as shown.
Place the machine on the floor with the top side
facing down and mount the undercarriage accord-
ing to the figure and instructions on the DVD.
Fasten the undercarriage to the ground with suita-
ble anchor/screw connections. The fastening must
be suitable to withstand the forces occurring dur-
ing working.
Due to the danger of accidents, this work must be
carried out by persons that are physically capable
of lifting the high weight of the machine.

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.
