OPERATING INSTRUCTIONS

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.

TRIM THIS EDGE

Inspect the batter y cables and terminals. Clean the terminals and apply electrical terminal sealers ( s e e y o u r d e a l e r ) t o p r ev e n t corrosion.

If you add water to the batteries and the temperature is below 0°C (32°F),make sure you charge the batteries or r un the engine for approximately two (2) hours. This procedure will prevent batter y freezing (see Batteries and Booster Batter y Connections in this manual.

Inspect the batter y 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 i n ea ch co mpon ent for th e 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.

Col d te mperatu re s can c aus e condensation to form in the fuel tank. Check the first stage fuel filter for water. If no water is found, extend the interval (see Diesel Fuel System in this manual).

4. COOLING SYSTEM - Check the coolant mixture before you operate in cold temperatures. A mixture of 50% ethy lene gly col and 50% water 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 star ting aids (see Cold Weather Starting in this manual).

TRIM THIS EDGE Bur 6-3581 LEFT PAGE

OPERATING INSTRUCTIONS 6. MACHINE WARM-UP - Once the engine has started, run the engine at half throttle (1 100 to 1 300 RPM) for a minimum of 10 minutes under no load. This will help warm t h e hy d r a u l i c o i l a n d t h e transmission oil.

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.

The hydraulic steering can become s l o w i n s ev e r e c o l d w e a t h e r conditions. Cycle the steering from full right to left a minimum of 3 to 5 times before you dr ive 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.

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 s h o u l d h a p p e n yo u M U S T g o 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 var y with temperature), then try again.

Engine Oil Change and Filter Replacement Change the engine oil and replace the filter after every 250 hours of operation or once a year whichever occurs first.

NOTE: For more complete removal of foreign material, change the engine oil while the engine is still warm from operation.

IMPORTANT: You must shorten the oil change interval if you use diesel fuel with a sulphur content of more than 0.5%.

Change the engine oil more frequently when the engine operating conditions are severe (frequent stopping and starting and high or low engine temperatures.)

1. Before draining the oil, have a container that will hold at least 22.7 litres (6 US gallons).

4. Turn the oil filter counterclockwise to remove. Discard the oil filter.

3. Open the rear engine access doors.

6. Apply a thin layer of clean grease or oil to the gasket of the new oil filter.

7. Turn the new oil filter onto the base until the gasket makes contact with the base. Continue to tighten the filter for 3/4 turn with your hand.
