2-20. OPERATION IN UNUSUAL WEATHER
a. Extreme Cold.
(1) General. Extensive preparation of the loader is required when extreme cold
weather is anticipated. Extreme cold causes lubricants to thicken or congeal, pre-
sents a risk of freezing batteries and diminishes their electrical efficiency, can
crack electrical insulation to cause short circuits, prevents fuel from vaporizing
readily to form the combustible mixture necessary for starting, and causes various
materials to become hard, brittle, and easily damaged. You must make sure the
cooling system has been filled with the appropriate anti-freeze solution to protect
the system against sub-freezing temperatures.
(2) Cooling System. Before the cooling system is drained and filled, inspect
the system for leaks and general condition. All deteriorated or damaged hoses must
be replaced. Make sure that all clamps are tight and that drain cocks are properly
closed. When anti-freeze is added to the cooling system, be sure ample space is
allowed for the required amount of anti-freeze. Be sure you operate the engine for
15 minutes to allow the solution to properly mix.
(3) Lubrication. Be sure that the correct grade of lubricant is applied to the
lubrication points. If necessary, drain and refill if the lubricant grade is not
correct for cold weather operation.
(4) Fuel System. Be sure precautions are taken to eliminate water and moisture
from the fuel system by draining and flushing the fuel tank, and draining off any
water from the fuel tank and filters at the end of each day’s operation, replacing
the fuel filter elements, and completely filling the fuel tank after each operating
period to avoid water condensation. The fuel tank must not be allowed to remain
partially empty over long periods of time and all ice and snow must be completely
removed from around the filler opening before refilling the fuel tank.
(5) Air System. At beginning and end of daily operation, drain water and sedi-
ment from the air reservoir.
(6) Engine Operation.
(a) Use the cold weather starting aid to start the engine.
