1. SHUTDOWN BYPASS-PREHEAT SWITCH
There are two functions built into this switch:
1. Preheats the fuel before beginning the starting
process. Press switch 10 seconds before
attempting start-up.

engine and for up to five seconds afterwards, allowing
oil pressure to build beyond shutdown set point.

To start the engine, hold this switch in the START

with water lift muffler systems can cause engine
damage.
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.
