7.2.2 Coupling
The coupling sprocket (Fig. 6/k) is subject to wear
and must be checked regularly (at least once a
year). When doing this the cooling coil (Fig. 6/v
1
)
must be cleaned each time by purging.
CAUTION
Defective coupling sprocket
Defective sprockets may lead to the rotor shaft
breaking.
To check the coupling switch the motor (Fig. 6/m)
off and ensure that it cannot be switched on again.
Undo the screws (Fig. 6/s
5
) on the motor fl ange
(Fig. 6/n). Remove the coupling half on the motor
side (Fig. 6/q) and the motor fl ange (Fig. 6/n) axially
and suspend with a lifting device. If the sprocket
(Fig. 6/k) is damaged or worn, then replace it. The
fan (Fig. 6/v) should also be checked for damage
from time to time and replaced if necessary.
NOTICE
Frequent starting up and high ambient tem-
perature
The service life of the sprocket (Fig. 6/k) is reduced
as a result of this.
Re-assemble in reverse order.
