Belt tension
(Fig.28-29)
Raise the motor via the handle (29.2). Now the belt can be placed in the desired slots (fig. 28). Lower
the motor until the belt has the correct tension. A properly tensioned belt can be pressed in the middle
under slight pressure over approximately the thickness of the belt. A belt that is too tight leads to
damage to bearings and premature wearing of the belt.
Check the condition of the belt regularly and change if necessary (order number: NXPA800). Only use
Robland replacement parts.
Adjusting the brake of the saw motor
If the run down time of the saw motor exceeds 10 seconds, then the brake will need to be readjusted.
This is done as follows: without removing the motor cowling, turn the bolt holding the ventilator fan on
the motor axle one 1/16th of a turn clockwise and make a brake test. When needed adjust the brake
furthermore untill it does not exceed 10 seconds.
The air gap between ventilator fan (brake disk) and brake liner (Ferrodo) is factory set at 0,25 mm, this
under normal conditions.
