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. 2-66
