1. SHUTDOWN BYPASS-PREHEAT SWITCH
There are two functions built into this switch:
preheating the engine and bypassing the engine safety
shutdown circuit, enabling a start. Hold the switch in
the ON position for approximately 10 to 20 seconds
before starting a cold engine. Holding the switch ON for
too long can burn out the glow plugs.
NOTE: Three position Engine Control switches must be
in the RUN position during preheating. Preheat switch
must be held in ON position during starting.
2. ENGINE CONTROL SWITCH
To start the engine, hold this switch in the START
position until the engine is running.
NOTE: Excessive cranking of marine sets equipped
with water lift muffl er systems can cause engine
damage. See page 8.
After the engine starts, release the switch and it will
return to RUN position. To stop the engine, hold the
switch in the STOP position.
NOTE: The rocker switch is used on Series 1 panels
only, and has a light that glows when the set is running.
