OPERATlON SECTION 1 Page 49 COLD WEATHER OPERATION If the temperature becomes low, it becomes difficult to start the engine, and the coolant may freeze, so do as foilows FUEL AND LU8RlCANTS Change to fiiel and oil with low viscosiry for all componen:s For details of the specified viscosity. see Ihe TABLE OF FUEL, COOLANT AND LUBRlCANTS * DCA4 is recommended for use an Cummins engines. f !n climates where the temperature is above -37°C [-34”F], use a coo&t mixture that contains 50 percent antifreeze Antifreeze is essential in any climate.
It bioadens the operating temperature range by lowering the cooiant freezing point and by raising its boiling point Do noi use more than 50 percent antifreeze in the mix%re unie!ib additional freeze protec!ion is required. Never use more than 68 percent antifreeze under any condi?icn. 11 Mai~.tx ~uppiementai co&n? additive leve!s at 1 irnit DC&i per 3 8 liters of soo!ani. / For de?di!i of changing the coolant, see WtiEN REQUIRED. BATTERY * As amtxent temperature drops, batten; capacitjj will drop, and electrolyte may ?,ometimes freeze if battery charge :s low Maintain Sattery at a charge level of approx.
100% and insulate it against cold temperature so that machine can be readily started the next morning. * Measure specific gravity of fluid and obtain rate of charge from the following conversion table: * When electrolyte level is low. add distilled water in the morning before work instead of after the day’s work instead of after the day’s work. Tiiis is to prevent fluid from freezing at night. WARNING! To avoid gas explosions, do not bring fire or sparks near the battery. a WARNING! If the electrolyte gels on your skin or clothes, immediately wash with plenty of clean water.
