Cab Temperature Controls

The cab environment is controlled by a climate control system that provides clean air conditioned or heated air for the operator.

The heater/evaporator/blower assembly is located under the cab floorboard and is accessible from beneath the windrower.

IMPORTANT: After storage for more than one week oil should be distributed throughout the system. Perform the following steps once the windrower is started.

Ensure heater shut off valve at engine is OPEN.

Turn blower switch to the 1st position, turn temperature control switch to maximum heating, and A/C control to OFF>

Start engine and operate at low idle until engine is warm.

Click A/C switch from OFF to ON for one second, then back to OFF for 5 to 10 seconds. Repeat this step ten times.

A/C Compressor Protection

The compressor is protected from excessive low and high pressures by two switches that shut down the compressor to prevent damage to the system.

If the air conditioning system is shut down by either switch, locate the source of the problem and correct it before operating the system.

Only certified professionals should service the HVAC system. See your dealer for complete information.
