INSTALLATION AND MAINTENANCE MANUAL
17
•
If it is not possible to install the belt on the tension pulley, we can move the motor (16). Loosen the bolt M8 (11)
which ensures the correct position of the motor. Move the motor to enable the belt installation and fasten it.
Tighten the securing bolt (11) carefully so that it would not deform the plastic washers (14,15).
•
Put a new belt PJ1473 (2) on the pulley. Installation of the belt is done in reverse order compared to its removal.
Take care so that the tension springs (7) would be fasten to openings in the pulley support and to the frame
hinge.
•
The belt must be placed in the correct grooves of the tension pulley, so that it could move in the middle of
the drum pulley width.
•
Testing force of the correctly tight belt between the drum pulley and tension pulley is 100 - 110Hz, (180 - 210N),
measured by tension meter for measuring the force in the belt.
•
Testing force of the correctly tight belt between the tension pulley and motor is 175 - 205Hz, (200 - 270N),
measured by tension meter for measuring the force in the belt.
•
If the belt tension does not correspond to determined values, we can adjust the belt tension by means of the bolt
which holds the springs or by additional moving the motor.
