OPERATING INSTRUCTIONS
OPERATING IN COLD WEATHER Template Name: OM_1_col Template Date: 1994_04_29 TRIM THIS EDGE
Cold weather conditions can cause special problems. During these conditions, your machine will require special attention to prevent serious damage. Cold weather maintenance will extend the service life of your machine.
Make sure to check for water in the fuel system. Cold temperatures can cause water to collect in the fuel tank. Check the fuel tank for water. If no water is found, extend the interval. See Draining Water from Fuel System, page 114.
1. B AT T E RY A N D E L E C T R I C A L SYSTEM: Clean the battery and make sure the battery is at full charge.
4. COOLING SYSTEM: Check the coolant mixture before you operate in cold temperatures. A mixture of 50% ethylene glycol and 50% water must be used in this machine. This mixture is used if the lowest ambient temperature is above -37˚C (-34˚F). It is recommended that ethylene glycol and water he used in your machine all year.
NOTE: A fully charged battery at -17˚C (0˚F) has only 40 percent of the normal starting power. Then, when the temperature decreases to -29˚C (20˚F), the battery has only 18 percent of the power remaining.

NOTE: If you add water to the battery and the temperature is below 0˚C (32˚F), make sure you charge the battery or run the engine for approximately two hours. This procedure will prevent battery freezing.
5. COLD TEMPERATURE STARTING AIDS: See your dealer for extra starting aids such as battery heater, engine oil heater, coolant heater, etc.
Preventing Damage to the Hydrostatic System in Cold Temperatures
Inspect the battery cables and terminals. Clean the terminals and spray a coat of battery terminal protector to prevent corrosion.
IMPORTANT: Below 0˚C (32˚F), run the engine at 1/2 throttle for 10 minutes with the transmission controls in the NEUTRAL position. Do not operate the hydraulic cylinders rapidly or against the stops rapidly until the hydraulic oil is warm. Increase the engine speed to 3/4 throttle and move the transmission control levers to 1/4 forward. Move the machine at no load for one minute or until the transmission runs normally.
2. LUBRICANTS: Use the correct viscosity oil in each component. As an example: SAE 30 engine oil at 0˚C (32˚F) increases the starting load by about 250 percent. Make sure you follow the recommended oil filter service as shown in this manual. 3. DIESEL FUEL SYSTEM: Check with your fuel supplier for the correct cold weather fuel. Diesel engine power will be reduced if wax particles are in the fuel filter. 58
