OPERATING IN COLD WEATHER

Cold weather conditions cause special problems. During these conditions your machine will require special start up, and warm up, and maintenance procedures for the best performance. Proper cold weather maintenance will extend the service life of your machine. 1.BATTERIES/ELECTRICAL

SYSTEM - Clean the batteries and make sure the batteries are at full charge. NOTE: A fully charged battery at -17˚C (0˚F) has only 40 percent of the normal starting power. At -29˚C (-20˚F) the battery has only 18 percent of the power remaining.

Inspect the battery cables and terminals. Clean the terminals and apply electrical terminal sealers (see your dealer) to prevent corrosion.

If you add water to the batteries and the temperature is below 0˚C (32˚F),make sure you charge the batteries or run the engine for approximately two (2) hours. This procedure will prevent battery freezing (see Batteries and Booster

Battery Connections in this manual.

Inspect the battery cables and terminals. Clean the terminals and apply electrical terminal sealer (see your dealer) to prevent corrosion. 2.LUBRICANTS - Make sure you follow the recommended oil and filter service for the engine and the hydraulic system as shown in this manual. Use the correct viscosity oil in each component for the ambient temperatures the machine is operated in (see Lubrication in this manual). 3.FUEL SYSTEM - Check with your fuel supplier for the correct cold weather fuel. Engine power will be reduced if wax particles are in the fuel filters. Check for water in the fuel system. Cold temperatures can cause condensation to form in the fuel tank. Check the fuel filter for water. 4.COOLING SYSTEM - Check the coolant mixture before you operate in cold temperatures. A mixture of 50% ethylene glycol and 50% w ater must be used in this machine. This mixture is used if the lowest ambient temperature is above -37˚C (-34˚F). If the ambient temperature is lower, adjust the mixture. It is recommended that ethylene glycol and water be used in your machine all year (See Engine Cooling System in this manual). 5. COLD TEMPERATURE STARTING AIDS See your dealer for extra starting aids (see Cold Weather Starting in this manual).

RPM) for a minimum of 10 minutes under no load. This will help warm the hydraulic oil and the transmission oil.

After engine warm-up, enable the pilot controls by pushing down on the right hand side of the switch on the instrument control panel. Apply and hold the foot brake, and cycle all hydraulic functions several times. In severe cold weather conditions, the hydraulic functions may be slow to respond. Cycling all the hydraulic system functions several times will warm the hydraulic oil and the hydraulic system components.

The hydraulic steering can become slow in severe cold weather conditions. Cycle the steering from full right to left a minimum of 3 to 5 times before you drive the machine. NOTE: Make sure there is clearance around the machine before steering the machine from right to left.

In severe cold weather conditions the brakes response can be slow.

The use of correct oil in the hydraulic/brake system is required.

Even with the correct oil in the hydraulic/brake system the first few times the brakes are actuated there may be some delay before the brakes are applied. The operator must actuate the brake pedal a minimum of 8 to 10 times before the machine is moved. When the machine has been correctly warmed up, apply the foot brake and hold, shift the transmission to forward push the park brake to the Off position and release the foot brake. Operate the machine in a clear safe area.

Check the full operation of the machine. DO NOT operate the machine in third or fourth gear until the transmission oil and axle oil have been warmed up and the machine moves freely. IMPORTANT: DO NOT operate the machine on the road until the transmission oil and axle oil have been correctly warmed up. Operate the machine in a clear safe area before road operation. 7.If the machine has been left idling in cold temperature, the engine will stay warm. But the hydraulic/brake oil and the axle oil will not stay warm. The oil and components can become cold and slow brake function response time. If this should happen you MUST go through the complete machine warm-up procedure. 8.The transmission is equipped with internal protection that does not allow the transmission to engage below -12 ˚ C (10 ˚ F). If the transmission does not engage below these temperatures, allow 2 to 4 minutes of running in neutral (this time will vary with temperature), then try again.
