COLD WEATHER OPERATION Care in using antifreeze Use a Permanent Antifreeze (ethylene glycol mixed with corro- sion inhibitor, antifoam agent, etc.) meeting the standard requirements as shown below. With permanent antifreeze, no change of coolant is required for a year. If it is doubtful that an available antifreeze meets the standard requirements, ask the supplier of that antifreeze for information. * Where no permanent antifreeze is available, an ethylene glycol an- tifreeze without corrosion inhibi- tor may be used only for the cold season. In this case, coolant must be changed two times a year (at the beginning and at the end of the cold season).
* Do not mix an antifreeze with one of different brand. * Absolutely avoid using any water leak preventing agent irrespective of whether it is used indepen- dently or mixed with an antifreeze. * Measure specific gravity of fluid and obtain rate of charge from the following conversion table: > Standard requirements for perma- nent antifreeze - SAE . . . . . J1034 . FEDERAL STANDARD ~................ O-A-548D * Never use any antifreeze made from alcohol which may be a cause of engine trouble. + When electrolyte level is low, add distilled water in the morning before work instead of after the day’s work. This is to prevent fluid from freezing at night.
A To avoid gas explosions, do not bring fire or sparks near the battery. A If the electrolyte gets on your skin or clothes, immediately wash with plenty of clean water. l Battery As ambient temperature drops, battery capacity will drop, and electrolyte may sometimes freeze if battery charge is low. Maintain battery at a charge level of approx. 100% and insulate it against cold temperature so that machine can be readily started the next morning. - 63 - W-04086
