Precaution measures for various temperature conditions
At high outside temperatures
Take the following precautions at high temperatures to prevent the loader from being damaged:
•
Regularly check the cooling system:
Keep the engine coolant and oil coolers clean
Make sure that the coolant level is always correct
Use the proper coolant mix.
Regularly check the cooling system for leaks
Regularly check the condition and tension of the fan pulley
•
Use engine lubricating oil of the proper viscosity class.
• Regularly check the engine air filter.
At low outside temperatures
•
Do not use starting aids such as ether. The manifold heating system can ignite the ether, causing an explosion.
•
Snow, mud and freezing rain reduce traction.
Reduce speed and avoid slopes under these conditions.
• Maintain the windshield cleaning fluid system and keep all windows clean. Visibility is a basic necessity for safe operation.
Additional starting aids may be required if the temperature is –18°C (0°F) or less. Typically, these aids are auxiliary engine oil and coolant heaters along with additional battery cranking capacity.

Hydraulic and lubricating fluids are more viscous when cold. When ambient temperatures are at or near the freezing point of 0°C (32°F), permit the engine, drivetrain and hydraulic system to warm up at idle speed until the temperature indicator for the system indicates warming has progressed.
•
Operate the wheel loader slowly and smoothly to accelerate the warming process.
• Observe the hydraulic system filter pressure display to determine if pressure is excessive.
•
Do not connect two 12V batteries in series (+ to –) and then connect the remaining battery poles to the starter or starter solenoid. This will damage the electrical system
Take the following precautions at low temperatures to prevent the loader from being damaged and to make the loader easier to start:
•
Use the proper coolant mix.
•
Use engine lubricating oil of the proper viscosity class.
•
Use diesel fuel for low temperatures.
•
Fill the fuel reservoir at the end of the work shift.
•
Make sure the battery is always fully charged.
•
Install the cold starting aid (see note above!).
