6.4. Checking the impeller
A jammed impeller triggers the integrated motor protection device and auto-
matically switches off the pump.
CAUTION: Before starting any
kind of work on the pump,
always disconnect the electric
cable from the power supply
to avoid inadvertent enabling
of the pump.
For troubleshooting purposes you must remove the 6 countersunk screws
in the base of the suction strainer on the bottom side of the pump. Remove
any visible soiling using a screwdriver or jet of water and use a screwdriver to
check that the impeller is moving freely. If the impeller is moving freely, replace
the suction strainer base and test run the pump. If the impeller fails to turn,
please contact the Rosenbauer customer service.
6.5. Retiring criteria
In case of a defective power cable, mechanical shaft seal, or other electrical
or mechanical defects, retire the pump immediately, or have it repaired by an
authorized repair shop.
6.6. Repairs
All repairs must be performed by the manufacturing works, or an authorized
and qualified service center. Original parts by the manufacturer must be used
in all cases.
CAUTION: There is a risk of fatal injury in case of unauthorized
modifications or repairs, or the use of non-original manufacturer parts!
CAUTION: Unauthorized modifications or repairs, or the use of
non-original manufacturer parts voids your warranty! We accept no
liability for damage caused by improper performance of repairs.
CAUTION: Please note that, according to product liability law, we are
not liable for damage caused by our machine but due to unqualified
