WAR NING
Unprotected rotating coupling
Risk of injury by rotating shafts!
Always operate the pump set with a coupling guard.
If the customer specifically requests not to include a coupling guard in PUMPIRAN
,
s
delivery, then the operator must supply one!
Observe all relevant regulations for selecting a coupling guard.
DANG E R
Risk of ignition by frictional sparks
Explosion hazard!
Choose a coupling guard material that is non-sparking in the event of
mechanical contact (see DIN EN 13463-1).

5.7.1 Motors with levelling screw
Fig.11: Motor with levelling screw
The coupling guard and step guard, if any, have been removed.
1. Check the coupling alignment.
2. Unscrew the hexagon head bolts (1) at the motor and the locknuts (3) at the
baseplate.
3.Turn the levelling screws (2) by hand or by means of an open-jawed wrench until
the coupling alignment is correct.
4. Re-tighten the hexagon head bolts (1) at the motor and the locknuts (3) at the
baseplate.
5. Check that the coupling and shaft can easily be rotated by hand.
6. Re-install the coupling guard and step guard, if any.
7. Check the distance between coupling and coupling guard. The coupling guard must not
touch the coupling.
5.7.2 Motors without levelling screw
Any differences in the centre heights of the pump and motor shafts are compensated by
means of shims.
