 Operating Procedure with Standard Controller

With your Belt Sander fitted with a selected belt, connect the Gesswein Power 
Hand Controller to an electrical supply and the Belt Sander to the Controller.

Set the Slide Rheostat on the Controller to “Low” or the “0” position. Put the 
Controller Main Switch to the “ON” position, which lights up a pilot light that indi-
cates your handpiece is ready to use.

To increase the speed of the handpiece, move the Slide Rheostat toward “High” 
or “10.” You can then begin working. When work is completed, put the Main 
Switch to “OFF.”

To operate your Belt Sander using the optional Variable-Speed Foot Rheostat 
or optional On/Off Foot Switch, please refer to the Power Hand 2X Controller 
Instruction Manual for proper connection. The handpiece will not rotate until the 
foot rheostat/switch is depressed. The rheostat provides infinitely variable speed 
control; the switch only turns handpiece on and off (operates at speed selected on 
control unit).

 Precautions

A.

   Before operating your Belt Sander, be sure the desired belt is properly 

secured around both pulleys.

B.

   Do not attempt to change belts while the handpiece is operating.

C.

   During use, avoid pushing too hard on the work tool or exceeding torque 

capacity of Belt Sander motor.

D.

   Always disconnect the Belt Sander from your Gesswein Controller by the 

plug, not the cord.

E.

   Do not use oil or lubricants of any kind. Doing so will cause damage to the 

handpiece bearings.

F.

   Do not subject power cord on handpiece to sharp bending or rough treatment. 

Such treatment could cause the cord wires to be broken.

G.

   Under normal circumstances, the Belt Sander will not overheat. If, howev-

er, your Belt Sander does overheat, please contact the Gesswein Repair 
Department.

 Maintenance

Changing the Belt Arm

To change Belt Arms, you must first remove the belt that is in place on the Belt 
Arm (see General Use). Once the belt has been removed, pull the Belt Arm out 
of the Belt Sander main body (see fig. 4) and replace with selected Belt Arm and 
appropriate belt.

Changing Arm Pads

If the Belt Arm Support Pad requires changing, remove the worn pad from the 
Belt Arm, and replace with a new Belt Arm Support Pad by removing the self-ad-
hesive backing and placing in the same position.

Changing Belt Arm Pulley

To replace the Belt Arm Pulley, unfasten the Belt Arm Screw (see fig. 5) located on 
the top of the Belt Arm. Gently spread the two plates sufficiently apart to remove 
the old pulley, and replace with a new one. Securely refasten the Belt Arm Screw.

Lubrication

It is not necessary to lubricate the Gesswein Belt Sander.

Cleaning

It may be necessary on occasion to blow accumulated dirt and grit away from the 
area surrounding the Drive Pulley. This can be facilitated by first removing the 
Protection Cover (squeeze sides with thumb and forefinger to remove).

When external surfaces of your Belt Sander become dirty, use a cloth slightly  
saturated with a neutral cleaning liquid. Do not use volatile liquids such as paint 
thinner or alcohol.
