Maintenance and Inspection
Regular maintenance and inspections are a necessity for continued
efficient functioning of the pump. If any abnormal conditions are
noticed, refer to the
Troubleshooting
section and take corrective
measures immediately. It is recommended that a spare pump be kept
ready in case of any problems.
5.1.1
Washing the pump
Remove accumulated matter from the surface of the pump and wash
it with clean water. Take special care to remove any debris from the
impeller.
5.1.2
Inspecting the pump exterior
Look for any peeling or chipped paint, and make sure the nuts and
bolts are fastened tightly. Any cracks in the surface should be repaired
by cleaning that area, drying it and then applying a touch-up coating.
Note:
Touch-up paint is not supplied. Note that some kinds of damage
or looseness may require that the unit be disassembled for repairs.
Please consult your nearest dealer or Wacker Neuson representative.
5.2
Storage
When the pump is out of use for an extended period, wash it and dry it
thoroughly, then store it indoors.
Note:
Always run a test operation before putting the pump back into
service.
If the pump is left in the water, it should be run a minimum of once a
week.
Lubrication
•
Inspecting Lubricant
Remove the oil plug and tilt the pump to drain a small amount of
lubricant. If the lubricant is milky white or has water mixed in with it, the
mechanical seal may be faulty. In this case the pump will need to be
disassembled and repaired.
•
Replacing Lubricant
Remove the oil plug and drain all the lubricant, then replace it with the
specified amount.
WARNING
Personal injury hazard from electrical shock or unexpected starting of the pump
motor.
Before inspecting 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.
