MAINTENANCE PRIOR TO START

HEATER / AIR CONDITIONING: CHECKING RATE OF AIR FLOW
☞
• If the filter fleece is too dirty it must be replaced.
1. Turn start switch to position "1".
2. Switch blower on.
3. Check if air flow at the air-outlet nozzles (1) and (2) to the
right and left of the steering column is strong enough.
Attention: The circulating air jets (arrow) must be open.
4. If insufficient air is coming out of the jets, either the filter
fleece in the heating/air conditioning unit is dirty and will
have to be cleaned or replaced or the condenser in the air
conditioning system is dirty and will have to be cleaned; see
"Maintenance Every 500 Operating Hours".
