Operating Procedures
NOTE:
Do not rely on your warning or shutdown
system 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 shutdown system is
activated:
a. Check the temperature gauge. If the temperature is
above 205°F (97°C), shut off the engine immediately.
b. Use the Trouble Shooting Guide on pages 18- 19
to isolate the cause of the overheat.
CAUTION:
Do not remove the water
fi
ll 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.
c. Make repairs and restart after the temperature
gauge registers below 180°F (83°C).
d
. Watch the temperature gauge regularly and turn
off the unit if the temperature rises above 200°F
(94°C). Repeat the troubleshooting process.
3. If the 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,
fi
ll 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 after a few seconds of operation.
c. If the oil level is normal, DO NOT restart the
engine. Call your Northern Lights or Lugger
dealer for assistance.
BREAK-IN PERIOD
1. Your engine is ready to be put into service. How-
ever, the
fi
rst 100 hours on a new or reconditioned
engine are critical to its life and performance.
2. Operate with an average of 75% load on your engine
for the
fi
rst 100 hours. Maintain no less than a 50%
load to ensure proper seating of the piston rings.
3. Oil consumption is greater during break-in as piston
rings take time to seat.
4. Your engine comes equipped with break-in oil.
Change engine oil and
fi
lter at 50 hours using API
Service Category CC, CD, or CE break-in oil.
Change the oil and
fi
lter again at 100 hours.
(Consult the lubricants section for oil
recommendation.)
5. Frequently check the engine temperature and oil
pressure
gauges.
