STARTING THE PUMP
Before starting the pump, be sure to check the following:
•
Make sure all hose couplings, covers and plugs are tight.
•
Check the oil levels in the sight glasses on the connection between the engine flywheel and pump volute.
The oil level should be in the middle of each sight glass.
The bearing oil and mechanical seal oil are each sealed by a shaft lip seal, and a vent to
atmosphere exists between these two lip seals to indicate oil leak from either cavity. If either
the bearing oil or mechanical seal oil lip seal leaks, oil will leak from the vent. This vent
should be checked for leakage prior to pump operation.
•
Check the engine oil level, coolant level and fuel level.
•
Make sure the engine starting battery is connected.
1.
Make sure the emergency stop switch is pulled out (deactivated).
2.
Turn the engine start switch key to the right “RUN” position. A startup screen will appear. After the startup screen
is cleared, the display will show readings on its virtual gauges. Once the gauges appear, crank the engine by
turning and holding the key switch in the “START” position until the engine starts. Refer to
for details.
3.
Allow the engine to run until it reaches a constant speed. Once it is running smoothly, the engine speed can be
adjusted with the Speed Control switch (
/
), located above the Engine Start switch on the control panel.
A. Press and release the Rabbit
icon to increase the speed.
B. Press and hold the Rabbit
icon to accelerate to full speed in a few seconds.
C. Press and release the Turtle
icon to decrease engine speed. (Press and hold for continuous deceleration.)
4.
The pump should self prime and begin to discharge liquid within minutes. The pump may not prime immediately
because the suction line must first fill with liquid. If the pump fails to prime within five minutes, stop it and check
the suction line for leaks.
5.
Use the Speed Control switch (
/
) to adjust the pump flow. Several factors can influence pump output:
•
The temperature, viscosity, and amount of entrapped solids in the liquid being moved.
•
The length, diameter, and number of bends of the intake and outlet hoses.
•
The total suction height (lift) of the pump.
•
The altitude above sea level where the pump is operating.
