Automatic Shutdown

This unit is equipped with a low oil pressure and high
coolant temperature automatic shutdown system. This
system will automatically shut off the fuel supply to stop
the engine if oil pressure drops too low or the engine
exceeds normal operating temperature. Return the main
circuit breaker to the OFF (O) position to reset the unit
after the cause of shutdown has been determined.

Light Operation

WARNING
Burn hazard. Never operate lights with a
damaged or missing lens cover. Lamps are
hot and pressurized while in use. Unprotected
lamps can shatter, causing severe injury.
1. Verify the unit is on and running smoothly.
2. See Figure 3-8. Switch the main circuit breaker (A)
ON (I).
3. Switch the individual circuit breakers for the lights
(B) ON (I), one at a time.
4. The ballast indicator lights (C) will turn on and
continue to get brighter as the lights warm up, and
then remain on. This confirms power is coming
from the ballasts to the lights.
