ADJUSTMENTS PRIOR TO MACHINE START ADJUSTING THE HEATING SYSTEM The heating capacity depends on the coolant temperature of the engine. Full heating capacity is only realised, if the engine is completely warmed up. You can realize maximum heating inside the cabin, if you open all air ventilation nozzles, set the temperature rotary switch to maximum heating power while switching on the fan with its high- est level. You may realize a comfortable temperature, if you open all air ventilation nozzles, set the temperature rotary switch to a com- fortable temperature and set the fan to an appropriately low air throughput.
To cool down the temperature inside the cabin, open all air venti- lation nozzles, set the temperature rotary switch to position 'Cold' and set the fan to its highest level. To prevent premature tiredness due to lack of oxygen, it is rec- ommended to open the door a little from time to time and to lock it in this position. Optionally, you may leave open the ventilation grid above the side window. 5-9 75 040 75 158
