Operation in Extreme Heat (Continued)
Electrical System. Check the electrolyte level in the battery daily, and fill to three-eight inch above the
plates with distilled water, if available. Clean, mineral free water may be used.
Operation in Salt Water Areas
a. Keep oil filler caps and plugs tight.
b. Be sure to clean and dry all fittings before lubricating.
Cooling System. Be sure the water in the cooling system is free from salt or alkali. Use an approved

Operation at High Altitudes
The engine in this unit is designed to operate under normal conditions up to 5,000 feet above sea level
without special service or adjustment.
Above 5,000 feet, the engine efficiency will be reduced. This is a normal condition which cannot be
prevented, but maximum performance can be maintained by following all service instructions carefully.
Be sure air cleaners are clean and free of objects that might restrict flow of air to the unit.
Be alert for pressure leaks that allow the coolant to boil with resultant loss of coolant. Inspect the
radiator cap and gasket frequently for tight sealing.
