SHUTDOWNS AND ALARMS
1. Your unit is fitted with a system to protect it from
high water temperature or low oil pressure.
a. Generator sets have shutdown systems to stop the
engine. They have no warning horns.
b. Other alarms and shutdowns are available as
optional equipment.
NOTE: Do not rely on your warning to the
exclusion of careful gauge monitoring. Watching
your gauges can prevent damage to the unit and
dangerous power losses.
2. Do the following when your warning or shutdown
system is activated:
a. Check the temperature gauge. If above 205°F
(96°C), remove the load and then shut off the
engine.
b. Use the Trouble Shooting Guide on page 22 to
isolate the cause of the overheat.
CAUTION: Do not remove the water fill
cap of an overheated engine. Escaping high
temperature steam can cause severe burns.
Allow the engine to cool and then remove the
cap slowly using protective clothing.
d. Make repairs. Restart your set after the
temperature gauge registers below 200°F (94°C).
e. Watch the temperature gauge regularly and
turn off the unit if the temperature rises above
205°F (96°C). Repeat troubleshooting.
3. If shutdown is activated and the temperature gauge
shows temperature within normal temperature range:
a. Check the engine crankcase oil level.
b. If the oil level is low, fill with recommended
lubricating oil and restart. Watch the oil pressure
gauge carefully and shut off the engine if it does
not show a normal reading (20-60 PSI) after a
few seconds of operation.
c. If the oil level is normal, DO NOT restart the
engine. Call your dealer for assistance.
