5.5 Replacement Parts
The table lists the parts that need to be replaced periodically. Replace these using
the recommended frequency as a guideline.
5.6 Disassembly and Reassembly
Before disassembling the pump, make certain the power supply (circuit breaker,
etc.) is turned off. Then, unplug the cable assembly from the receptacle or detach it
from the terminals. To avoid electrical shock, do not work with wet hands.
Do not check the operation of any parts (impeller rotation, etc.) by turning on the
power while the unit is partially assembled. Failure to observe these precautions
may result in a serious accident.
Do not disassemble or repair any parts other than those designated here. If repairs
are necessary in any other than the designated parts, consult your nearest dealer
or Wacker Neuson representative. Improper repairs can result in electrical leakage,
electrical shock, fire, or water leaks.
After reassembly, always perform a test operation before resuming use of the
pump. Improper assembly will cause the pump to malfunction, resulting in electric
shock or water leaks.
The procedure for disassembly and reassembly is shown here to the extent
necessary for impeller replacement. A specialized environment and facilities are
necessary for work on the mechanical seal and the motor parts. Contact your
nearest dealer or Wacker Neuson representative in the event such repairs are
necessary.
