OPERATION 14. COLD WEATHER OPERATION 14.1 LOW TEMPERATURE PRECAUTIONS 14.1.1 FUEL AND LUBRICANTS Change to fuel and oil with low viscosity for all components. For details of the specified viscosity, See 20 FUEL, COOLANT AND LUBRICANTS ACCORDING TO AMBIENT TEMPERATURE on page 3-9. 14.1.2 COOLANT WARNING Keep the antifreeze fluid away from an open flame. Never smoke when near the antifreeze. NOTICE Never use methanol, ethanol, or propanol-based antifreeze. Never use any water-leak preventative agent, regardless if it is used by itself or mixed with an antifreeze. Do not mix one antifreeze brand with another brand.
For details of the antifreeze mixture requirements, See 20.6 COOLANT SPECIFICATIONS on page 3-12. Use a permanent antifreeze (ethylene glycol mixed with corrosion inhibitor, antifoam agent, etc.) meeting the standard requirements shown below. Permanent antifreeze needs to be changed only once a year. Use only permanent antifreeze that meets the below standard specifications.

.O-A-548D 14.1.3 BATTERY WARNING To avoid gas explosions, do not bring fire or sparks near the battery. Battery electrolyte is dangerous. If it gets in your eyes or on your skin, wash it off with large amounts of water, and consult your doctor. When the ambient temperature drops, the battery’s capacity will also drop. If the battery’s charge ratio is low, the battery electrolyte may freeze. Maintain the batery charge as close to 100 percent as possible. Insulate the battery from the cold temperatures so that the machine will start easily the next morning. REMARKS Measure the specific gravity and calculate the rate of charge from the following conversion table.
