EXTREME ENVIRONMENTAL CONDITIONS.
Operation in Extreme Cold [23F (-5C) to -51F (-46C)].
a.
The generator is designed for use in ambient temperatures as low as -51F (-46C). To ensure satisfactory
operation, the following steps should be taken.
(1)
When possible, provide shelter from winds, freezing rain, and drifting snow. Position
generator set behind a wind barrier.
(2)
When operated in an enclosed area, be sure that proper provisions are made for removal
of exhaust gases.
CAUTION
Be careful not to scrape, scratch, gouge, or in any way damage the
generator set. Avoid moving wiring as much as possible.
(3)
Remove accumulated snow or ice, if possible, by moving the generator set to a heated
enclosure and allow the accumulation to melt after first wiping or brushing away loose
deposits. When a heated enclosure is not available, remove snow or ice by wiping,
brushing, or carefully picking the deposits away.
(4)
For extreme cold weather conditions, MIL-PRF-46167, OW30 oil is recommended.
WARNING
Avoid contacting metal items with bare skin in extreme cold weather.
Failure to observe this warning can result in personal injury.
(5) Keep fuel tank at least 3/4 full during cold weather operations.
Operation in Extreme Heat [Above 120F (49C)].
b.
(1)
When operating in extremely hot temperatures, attempt to place the generator set in a
shaded area.
(2)
Provide as much ventilation as possible.
(3)
Keep all engine air passages and end cover openings clean and free of obstructions.
