3.9.3.Tips for using the heating system
●
Before starting the engine, make sure the ventilation system is turned off (you can simply turn off the
ventilation fan), to avoid the tractor battery operation under overload.
●
If the ventilation system has been running at full power for a long time, do not turn it off immediately. Before
turning it off, have it running at minimum speed for at least 20 seconds.
●
With the heating system turned on, you can feel air flow immediately from the air outlet. If no air flow, turn
off the system and locate the fault.
●
To demist the windshield quickly, simply turn the control switch to max speed. Open the outlet 3, and close
the outlet 1. This ensures that the entire stream of warm air flows directly to the windshield.
●
Do not use the heating system in a particularly dusty environment.
