6.1.1 Checking the rotation direction
The drive shaft direction of rotation is shown by
the rotation direction arrow (Fig. 2/O) on the mo-
tor fl ange.
a) Start the motor briefl y (max. two seconds) to
check the direction of rotation. When looking at
the motor fan, it must rotate anti-clockwise.
NOTICE
Incorrect direction of rotation
Operating in the wrong direction of rotation leads
to damage to the machine.
Use a phase sequence indicator to check the direc-
tion of rotation (clockwise rotating fi eld).
b) After correcting the direction of rotation if neces-
sary, start the motor again and stop it again after
2 minutes in order to top missing oil up to the
upper edge of the sight glass (Fig. 2/I). The fi lling
point must not be open when the pump is run-
ning.
6.1.2 Setting the operating range
The operating range can be set by turning the
adjusting bolt (Fig. 2/X, 4/X).
