HVAC Blower

Check and service the HVAC system blower each season or annually.

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

To distribute oil throughout the system, perform the following steps whenever the machine is first started after storage for more than one week or at the beginning of the season:

1. Confirm that the heater shut-off valve at engine is open.

2. Turn blower switch to the first position, turn temperature control switch to maximum heating and A/C control to off.

3. After confirming that all bystanders are clear sound the horn a start the engine. Operate at low idle until engine is warm.

4. Switch A/C from OFF to ON for one second and then back to OFF for 5 to 10 seconds.

5. Repeat step ten times.

The A/C compressor is protected from excessive low or high pressure by two switches that shut down the compressor to prevent damage to the system.

If the A/C shuts down by either switch or while performing checks contact your dealer.
