FLUIDS CONTINUED

Air Conditioning

TYPE - The cab on your detasseler is equipped with a R134a air conditioning system.

RECHARGING - Recharge it only with R-134a refrigerant. If your air conditioning system is mistakenly charged with R-12 refrigerant, serious problems, such as compressor seizure, may result. Therefore, confirm refrigerant before recharging system.

If you do not have the proper recharging equipment, it is recommended that you allow an independent service agent service your air conditioning system.

VII. SERVICE AND MAINTENANCE Grille Screens

Filters

In order to maintain maximum air flow through the engine cooling system’s radiator, oil cooler, and air conditioning condenser, the cooling air intake grille screens must be inspected often and periodically removed for cleaning.

NOTE:

Failure to keep cooling systems clean can cause over heating and damage to the hydrostatic system and/or engine.

REMOVAL - The side grille screens are easily removed by sliding them up out of their housings (fig. 7.18). The top screen is held in place by two bolts (fig. 7.19) and may also be removed for cleaning.

CLEANING - Compressed air will dislodge most large trash or loose dirt after the screens have been removed (fig. 7.20). Blow out the screens away from the machine. Water from a pressurized hose may also be used, or if necessary the screens may be soaked in soapy water and scrubbed with a brush.

NOTE:

When cleaning cooling fins of the radiator, oil cooler, or A/C condenser with compressed air or water, be careful not to damage cooling fins which may impair cooling capabilities.
