Always use the proper grade of fuel to facilitate starting and achieve smoother engine operation in extremely cold weather.

e. Electrical System. Clean and tighten all electrical connections. See that the electrical wiring is free from ice

particles and frozen moisture Check the battery cables and see that the cables and terminals are clean, free of ice or

snow, properly connected, and tight. Check the specific gravity and freezing point of the electrolyte in the battery (refer to

f. Personal Safety Precautions. Do not touch metal parts with bare hands in extremely cold temperatures. See that

the step wells and the operator's platform are free from ice, slush, and snow.

g. Compression and Steering Rolls. Drain all water from the compression and steering rolls. If extra weight is

needed, fill the rolls with used oil or an antifreeze solution (refer to table I).

h. Sprinkler Tank. Drain the sprinkler tank. Make sure that the sprinkler tank, pipes, hose, and connections are

completely dry.

39. Operation in Extreme Heat

a. Lubrication. Lubricate the road roller according to LO 5-1185.

b. Preventive. Maintenance Services. Perform the services outlined in paragraphs 51 through 54.

c. Radiator. Check the radiator and see that the coolant is at its proper level, just below the overflow pipe. Fill the

radiator if necessary. Inspect the radiator and cooling system for leaks.

d. Battery. Check the electrolyte level in the battery daily. Add distilled water if necessary.

e. Electric Wiring. Electric wiring insulation tends to swell up and soften in extremely high temperatures. Check the

electric wiring system for swollen and broken insulation. Handle the wiring carefully and do not damage the insulation.

f. Side Doors. If possible, operate the road roller with the side doors open or removed.
