Maintenance Note: Determine the left and right sides of the machine from the normal operating position. Recommended Maintenance Schedule(s) Maintenance Service Interval Maintenance Procedure After the first 100 hours • Check all connections for tightness. Every 50 hours • Check the refrigerant level. Every 250 hours • • • • • Every 500 hours Every 2 years Check the compressor magnetic clutch for correct operation. Check the water drain for blockage, and clean it as necessary.
Checking the Refrigerant Pressure 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). When using the air-conditioning system the operating pressure is different on the suction side and the pressure side of the compressor.
3. Check the level after this period and top up is necessary. Note: The occasional air bubble is acceptable. Checking the Compressor Magnetic Clutch Service Interval: Every 250 hours The compressor magnetic clutch is operating correctly if it clicks when it is turned on (Figure 7). 1 g019083 Figure 8 1. Drain tube Note: If the blockage is not reachable with a flexible unblocking tool, the other end of the tube can be disconnected and blown out with compressed air (Figure 9). 1 1 g019082 Figure 7 1.
Storage Refer to the traction unit Operator’s Manual for details on storing the machine. 1 2 g019081 Figure 10 1. Compressor 2. Check the belt deflection here. 3. Increase or decrease the compressor-belt tension and tighten the bolts. 4. Check the deflection of the belt again to ensure that the tension is correct. Locating the Fuses The fuse box is located in the cab roof liner in front of the driver. 1 3 2 4 g018402 Figure 11 1. 25 amp 3. 5 amp 2. 15 amp 4.
