12. Engine preheat
Wait until the engine preheat lamp turns OFF before starting the engine. The engine preheat lamp
will illuminate when the incoming air needs to be preheated in cold temperatures.
13. Low fuel
The low fuel warning lamp will illuminate and the audible warning will sound for a few moments when
the machine is low on fuel. Monitor the fuel level at the fuel gauge. Do not allow the machine to
run out of fuel.
14. Engine air filter
The engine air filter warning lamp will illuminate if there is an air filter restriction. It will illuminate
briefly when the ignition switch is turned on. If the engine air filter lamp remains illuminated, stop the
engine and check the engine air filter.
15. Engine coolant
The engine coolant warning lamp will illuminate and the audible buzzer will sound when the engine
coolant temperature is too high. Monitor the coolant temperature with the coolant temperature
gauge. If the engine coolant warning lamp illuminates and the audible warning sounds, run the
machine at idle speed. If this does not correct the problem, stop the engine immediately, and check
the machine coolant.
