CONTROL BOX COMPONENTS
Figure 8. Pump Control Box Components
1. Throttle Control Knob – This is a variable speed type
control. Turning the throttle lock left (CCW) unlocks the
throttle allowing the throttle control cable to be pulled out to
the desired position. Once the desired engine speed has
been achieved, turning the throttle lock to the right (CW)
locks it in place. Use the fine tune adjustment knob to fine
tune the engine rpm's.
To place the engine in idle, press the top button inward all
the way.
3. Battery Charge Indicator Lamp – Indicates if the electrical
system is charging properly. If the
Battery Charge
Indicator Lamp
is lit, this is an indication that the charging
system is malfunctioning. STOP the engine and remedy
the electrical charging problem.
4. Water Temperature Lamp – Indicates high engine water
temperature (220 degrees Fahrenheit) this lamp will be lit.
STOP the engine immediately if this lamp comes on. NEVER
run the engine when this lamp is on.
5. Pumping Control Switch – This 3-position switch controls
the pumping of the pump. The
left most
position is for use
with the remote control unit, the
center
position is for normal
pumping operation, and the
right most
position (OFF)
prevents pumping.
6. Remote Control Input Connector – Insert the remote
control input cable into this connector.
7. Ignition Switch – Insert the ignition key here to start the
engine. Turn the key clockwise to the ON position, then
continue turning clockwise to the START position and
release. To stop the engine turn the key fully counter-
clockwise to the
STOP position.
8. Hourmeter– Display's the number of hours the pump has
been in use.
ALWAYS
unlock the throttle control
before it is pushed in because if this
is not done first, possible damage
could result to the locking
mechanism.
