• Use proper diesel fuel for the ambient temperature.
• Use engine oil with the proper viscosity. For further information, see En-
gine Oil Viscosity on page 74.
• Check the engine coolant mixture for proper antifreeze mix.
• Make sure the battery is fully charged.
• Check to see if the battery connections and the connections to the
starter and engine block are clean.
• Start the engine. For further information, see Starting and Stopping the
Engine on page 40.
Hydraulic system
• Use proper hydraulic oil.
• Prevent damage to the hydraulic system by operating the machine at low
loads. Follow the warm-up procedures before using the machine at full
load.
Hot temperatures
Hot temperatures affect the engine and the hydraulic cooling systems.
The following are actions that help minimize issues with overheating of the
machine.
Engine/cooling
• Check the engine coolant mixture for proper antifreeze mix.
• Check the engine coolant level.
• Check the radiator cap for damage. Replace the cap if it is damaged.
• Keep the radiator core clean by removing dirt and debris.
• Use engine oil with the proper viscosity.
Hydraulic system
• Use proper hydraulic oil.
• Keep the oil cooler core clean by removing dirt and debris.
• Operate the machine at a lower load.
• When operating an attachment, avoid the following; otherwise, the hy-
draulic system will run over a relief valve, resulting in excessive heat
build-up in the hydraulic oil:
– Holding the right hand lever or joystick in place when the attachment
has been fully extended or retracted
– Holding the auxiliary lever in place when an attachment stops mov-
ing
• Avoid driving for excessive amounts of time.
