Engine warm-up
After the engine has started, allow it to warm up at slightly increased idling speed until it
reaches its operating temperature of 70 °C (158 °F) (coolant). Run the engine with no load
during the warm-up phase (raise control lever base on the left). During the warm-up
phase, check for unusual noise, exhaust color, leaks, malfunctions or damage. In case of
malfunctions, damage or leaks, park and secure the machine, and find out the cause for
the damage and have it repaired.
3.14 Jump-starting the engine (supply battery)
Safety instructions
• Never jump-start the engine if the battery of the machine is frozen – explosion hazard!
☞
Dispose of a frozen battery!
• The excavator must not touch the jump-starting vehicle when connected with jump
leads – sparking hazard!
• The external power source must deliver 12 V; higher supply voltages will damage the
electrical system of the vehicles!
• Use only authorized battery jumper cables which conform to the safety requirements
and which are in perfect condition!
• The jump lead connected to the positive + terminal of the starting battery must never be
brought into connection with electrically conductive vehicle parts – risk of short circuit!
• Route the battery jumper cables so they cannot catch on rotating components in the
engine compartment!
