OPERATION 3.2 Auxiliary ventilation in cab roof 3.3 Air conditioning Text-module WARNING: All repair and maintenance work must be carried out by qualified personnel only. Avoid all contact with liquid coolant. If accidentally splashed in the eyes, seek medical advice immediately. No welding should be carried out on or near any parts of the air conditioning systems! Risk of poisoning! Maximum ambient temperature for coolant 80 ° C. Check the V-belt only while the engine is stopped. Attach the protective grille again. CAUTION: When using the tractor for spraying operations (e.g. weed or pest control), fit filter cartridge (aerosols). Use only fan speed 1.
After each spraying operation, replace the filter cartridge with a normal cartridge. Follow the instructions given with the filter. Cab and filter do not guarantee 100% protection against harmful chemicals. Follow the manufacturer's instructions! Operation_Pic_number:1 Operation_Pic_number:1 Fig.37 Text-module Fig.38 Recirculated air/fresh air (A) MIN = 100% recirculated air - 0% fresh air. MAX = 0% recirculated air - 100% fresh air. N = Normal setting approx. 80% recircu- lated air - 20% fresh air. 0 = No fresh air. Start engine tractor (air conditioning only works with the engine running). Switch on blower with selector (A). Switch on air conditioning with selector (B).
Indicator lamp (C) shows that the system is working. The control knob position determines the mix between recirculated and fresh air. Text-module The air flow is controlled by and directed through nozzles (in cab roof cladding). MIN = Minimum blower output, cooling power. MAX = Maximum blower output, cooling power. 0 = Blower / air conditioning OFF. Text-module Blower (B) MIN = Minimum blower output. MAX = Maximum blower output. 0 = Fan off. Depending on the selector position, the blower output and cooling power can be increased ste- plessly. Depending on the selector position, the blower output can be increased steplessly. NOTE:
For health reasons it is advisable not to allow the air inside the cab to drop by more than ap- prox. 5 - 8 ° C below the outside temperature. Do not expose yourself directly to cold draughts - danger of catching cold! For energy economy and greater efficiency, we recommend using the recriculated air mode. 32
