CAUTION
During PMCS it is necessary to run the
engine to be sure that the work has
been accomplished satisfactorily. Since
the pump is directly coupled to the
engine, the pump will run when the
engine runs. Do not run the pump
without water in the volute. This will
destroy the mechanical seal, causing
pump failure. When necessary to run
the pump for longer than a few sec-
onds, make sure that suction and dis-
charge hoses are installed and a source
of water to be pumped is available.
Start engine, prime and operate pump
to duplicate normal operation and to
prevent pump from overheating.
NOTE
Instructions for starting, running, and
stopping the engine are located on the
control panel assembly.
