Fan, Heater and Air Conditioning System Controls

The three-stage fan switch (A) and the heater control knob (B) are located at the front of the cab roof.

IMPORTANT: At ambient temperatures below 0°C (32°F) operate the compressor by switching on the air conditioning system for 10 to 15 minutes at least once per month. Run the engine at 1500 rpm. By doing this the seals in the compressor are lubricated and prevented from becoming dry and brittle.

The air conditioning system (if equipped) is operated by means of the following controls:

· Switch (C) operates the three-speed fan and the electromagnetic compressor clutch,

· Thermostat control knob (D) for adjusting the desired temperature.

NOTE: When the air conditioning system is switched on, the heater control knob (B) must be turned to OFF position.
