Operation PST3/PSTF3 750

COUNTERMEASURE: If the supply voltage is outside the tolerance,
possible causes are the power supply capacity or an inadequate
extension cable. Look again at the wiring diagram and make sure the
conditions are proper.
In case of very excessive vibration, unusual noise or odor, turn off the
power immediately and consult your nearest dealer or Wacker Neuson
representative. Continuing to operate the pump under abnormal
conditions may result in electrical shock, fire, or current leakage.
Operation
The pump may become very hot during operation. Be careful not to
contact the pump accidentally to avoid being burned.
Make sure no extraneous objects such as pins, nails or other metal
objects are sucked into the pump. These can damage the pump or
cause it to malfunction, and can result in electrical shock or electrical
leakage.
When the pump is not used for an extended period, be sure to turn off
the power (circuit breaker, etc.). Deterioration of the insulation may
lead to electrical leakage, electrical shock, or fire.
In case of a power outage, turn off the power to the pump to avoid
having it start unexpectedly when the power is restored, presenting
serious danger to people in the vicinity.
Pay careful attention to the water level while the pump is operating. Dry
operation may cause the pump to malfunction.
Note: See section “Operating water level” for the water level
necessary for operation.
If the protection system operates due to an overload or malfunction,
causing the pump to stop, first investigate and remove the cause
before restarting.
Sharp bends in the hose, especially near its base, may cause air
pockets to form resulting in idle operation. Lessen the degree of
bending while continuing to operate the pump.
