9.FAN
If broken filters have caused dust to
blow up through the fan, this will very
quickly cause unbalance.
Fan has to be dismounted immediately,
cleaned and checked. If still not in
balance, fan has to be replaced by a new
one.
If the fan is driven while unbalanced, the
hydraulic motor bearing will be affected
and can lead to replacement of the
complete motor unit.
10. HYDRAULIC MOTOR
10.1 Check that the motor gets necessary
oil volume at correct working
pressure
10.2 Also check that the motor is correctly
connected with hydraulic hoses of
recommended diameter
If points 10. 1 and 10.2 are fulfilled and the fan
still is not running at 4500- 5000 rpm, there is
probably an internal leakage in the motor. The
motor should then be replaced
