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.
Oil Inspection and Oil change
Note:
Worn oil and other waste products should be disposed of by a
qualified agent, in accord with applicable laws. The oil plug packing
should be replaced each time the oil is inspected or changed.
Inspecting Oil
Remove the oil plug and tilt the pump to drain a small of oil. If
the oil is milky white or has water mixed in with it, the mechani-
cal seal may faulty . In this case the pump will need to be disas-
sembled and repaired.
Replacing oil
Remove the oil plug and drain all the oil, then replace it with the
specified amount.

Prior to Disassembly and Reassembly
WARNING
Before disassembling the pump, first detach the cabtyre cable from the
receptacle or terminals, after making certain the power supply (circuit
breaker, etc.) is turned off. To avoid electrical shock, do not work with wet
hands. Never check the operation of any parts (to check the rotation of
the impeller) by turning on the power while the unit is partially assembled.
Failure to observe these precautions may result in 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
with your nearest dealer or Tsurumi 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 Tsurumi repre-
sentative in the event such repairs are necessary.
