✓ The coupling guard and its footboard, 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 adjusting screws (2) by hand or by means of an open-end wrench until
the coupling alignment is correct and all motor feet rest squarely on the
baseplate.
4. Re-tighten the hexagon head bolts (1) at the motor and the locknuts (3) at the
baseplate.
5. Check proper functioning of coupling/shaft.
Check that coupling/shaft can easily be rotated by hand.
WARNING
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 KSB's
delivery, then the operator must supply one!
▷ Observe all relevant regulations for selecting a coupling guard.
DANGER
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).
6. Fit the coupling guard and its footboard, if any.
7. Check the distance between coupling and coupling guard.
The coupling guard must not touch the coupling.
