7.2.3 Drive Coupling
The coupling insert (Fig. 13/k) is subject to wear and
must be checked regularly (at least once a year).
CAUTION
Damaged or worn coupling insert may lead to
rotor shaft breakage.
To inspect the coupling, switch off the motor and
lock out the power supply.
Suspend the motor (Fig. 13/m) on the eyebolt by
means of lifting equipment.
Undo the screws (Fig. 13/s
5
) on the motor flange.
Remove motor and the coupling half on the motor
side (Fig. 13/q) from the motor flange housing
(Fig. 13/n) axially. If the insert (Fig. 13/k) is damaged
or worn, then replace it.
NOTICE
Frequent starts and stops as well as high
ambient temperatures reduces the life of the
coupling insert.
Re-assemble in reverse order.

7.2.4 Cooling
Check the cooling water system and the pipes
monthly.
Continuous flow cooling
The Y-strainer (Fig. 5/U

) must be cleaned
periodically, depending on the cooling liquid quality.
To do this unscrew the plug and clean the built-in
mesh screen.
