    Warning

    Working on the machine without the cab support bracket increases your risk of injury.

    Before carrying out maintenance underneath the operator platform and cab, install the cab support bracket.

    Caution

    If you leave the key in the ignition switch, someone could accidently start the engine and seriously injure you or other bystanders.

    Remove the key from the ignition before you do any maintenance.

    Important: Maintenance or repairs on the heating system should be carried out by an authorized Toro distributor or a specialist in vehicle heating systems.

    Important: All work on the refrigerant part of the air-conditioning system should be carried out by qualified personnel.

    • You can use the air-conditioning system for many months of the cutting season. Follow the regular prescribed maintenance to prolong the life of the system and ensure efficient operation. Failure to carry out the prescribed and documented maintenance could invalidate the warranty on the system and its components.

    • Even if the air-conditioning system is used infrequently, follow the maintenance schedule, as aging and refrigerant loss can occur with time.

    • Low levels of refrigerant can reduce the efficiency of the air-conditioning unit.

    • Extremely low levels can cause the low-pressure switch to shut down the system.

    • To check the refrigerant level, there is an integrated sight glass in the collecting tank. After filling, run the system for 5 minutes to allow all air bubbles to be purged from the system. Check the level after this period and top up is necessary. The occasional air bubble can be accepted.

      Important: Do not spill compressor oil on the vehicle surface. It can cause discoloration of vehicle paint and deterioration of acrylic or ABS plastic components.

    • When attaching the refrigerant hoses, oil the sealing rings with refrigerant oil.

    • After removal of refrigerant hoses from the air-conditioner system, always replace the O-rings with new ones specified for refrigerant 134A.

    • When tightening or loosening fittings, always use 2 wrenches to prevent the tubes from twisting.

    4. Rotate the compressor to increase or decrease the belt tension, and tighten the bolts.

    5. Repeat step 2 to ensure that the belt tension is correct.

    6. Close the hood, and latch it.

    Checking the Refrigerant Pressure

    When using the air-conditioning system the operating pressure is different on the suction (low pressure) side and the pressure (high pressure) side of the compressor; refer to Figure 38.

    This pressure difference is influenced by the speed of the compressor, the inside temperature of the vehicle, the outside air temperature and the relative air humidity.

    Pressures that differ from those in the table below indicate a possible fault in the system.

    To check the pressures, set the compressor speed to 2000 rpm with an air temperature between 20 and 40 degrees C (68 and 104 degrees F). Operate the blower at position 3 (fastest speed setting).

    Troubleshooting the Pressure Readings

    During the compression test, deviations from the values in the table may be measured. Locating the cause can determine whether a part requires repair or replacement.

    The following is a short list of some pressure deviation that may be measured and some possible causes.

    • Pressure on high-pressure manometer too high

      • The air volume in the condenser is too small.

      • Refrigerant quantity is too high

      • The dryer/filter is blocked.

    • Pressure on high-pressure manometer is too low

      • The refrigerant quantity is too low (check the sight glass).

      • The compressor speed is too low (check the drive belt for slip/tension).

      • There is a fault with the compressor.

    • Pressure on low-pressure manometer too high

      • The expansion valve is incorrect.

      • The compressor speed is too low (check the drive belt for slip/tension).

      • There is a fault with the compressor.

    • Pressure on low-pressure manometer too low

      • There is restriction in the suction or pressure hoses.

      • The expansion valve is incorrect.

      • The refrigerant quantity is too low (examine the sediment bowl).

      • The air volume in the evaporator is too small.

      Have a qualified person examine and repair all deviations in pressure from the values in the table.

    Important: Do not allow refrigerant to discharge into the atmosphere. Before opening or disconnecting parts from the refrigerant circuit, empty the refrigerant into a specified recycling bottle, and dispose of it correctly.
