7- AUXILIARY ELECTRICAL CURRENT RECEPTACLE

The machine is equipped with a 24Vdc auxiliary electrical power supply.

8- STARTING SWITCH

This switch is a rotary type and can be activated by a starting key. It has four positions:

A - ENGINE OIL PRESSURE GAUGE

The engine oil gauge indicates the pressure at which the engine oil is circulating through the engine. The red area means insufficient pressure. The green area means normal operating pressure, and the yelow area, excessive engine oil pressure.

B - ENGINE COOLANT TEMPERATURE GAUGE

-The GREEN area indiates a normal operating temperature 80 to 950C (176 to 2030F) -The WHITE area indicates low temperature. -The RED area indicates high temperature.

WARNING If during normal operation, the coolant temperature enters and stays in either the WHITE or RED area, stop the engine to check the cause of the problem.

C - FUEL LEVEL INDICATOR GAUGE

The green area indicates the normal operating level. When the marker reaches the red area, it means the reserve level, approximately 75 liters (20 gal ). Refill the tank using strained fuel as recommended. Refill the tank at the end of each work day, to avoid the water condensation, during idle periods. Never let the fuel tank run dry, because this will causes air to enter into the fuel system and will be necessary to purge the system.

D - TRANSMISSION OIL PRESSURE GAUGE

The marker on the transmission oil pressure gauge must stay within the green area, which indicates normal operating pressure. If the marker enters the red area, it is a signal that the oil pressure is too low.

WARNING Do not operate the machine in this conditions. Stop and check the cause of the problem. E - TRANSMISSION OIL TEMPERATURE GAUGE

2.1- REFRIGERANT CHARGE

For leak test and/or gas charging use air conditioning compressor taps A and B only.

1. Add 50 grams (1.76 oz) of R134a and allow system to build up to 10 bar (145 psi) by applying nitrogen. 2. Preceed with the gas leak test. Should a leak be confirmed, evacuate the system, repair the leak and repeat the leak test. 3. Connect the service manifold hoses. 4. Connect a vacuum pump to the service manifold center fitting 5. Open the service manifold valves and turn the vacuum pump on. 6. Allow 20 minutes for service manifold pressure gages to indicate 26 inHg vacuum. 7. Shut service manifold valves and disconnect the vacuum pump. 8. Connect charging cylinder hose to the service manifold, open the service manifold high side valve and charge 1200 grams (2.6 lbs) of R134a. 9. Shut the service manifold valve, remove gas hose and repeat the gas leak test. 10. Disconnect the service manifold and install service valve covers. 2.2- RECOMMENDATIONS 1. Turn on air conditioner only when the vent is not blocked. 2. Make sure the evaporator vents are not blocked. 3. Should system perform below specification, inspect: the system refrigerant pressure; the operation of evaporator vent and fan unit; the evaporator for obstructions. 4.Operate air conditioning unit for at least 10 minutes/week. 5. When the engine is at high rpm, operate fan at maximum speed. 6. Periodically check the external cleanliness of the condenser vents (never operate the condenser with 20% or more vent blockage). 7. Close all doors and windows when operating the air conditioner. 8. For fast cooling, use the cabin internal air (recirculation control).

2.3- SYSTEM MAINTENANCE

1. Perform leakage test every six months. 2. Clean the condenser monthly or whenever the condenser air inlet shows 20% obstruction. 3. Clean air conditioning filter monthly or whenever air flow reduction is noticed. 4. Using an oil compatible with R134a for top off: when adding a component; after any component replacement; after reparing R134a leakage. Topping off may not be required following a replacement of compressor (some compressors are filled with oil at the plant, those compressors indicate oil filled). 5. Following refrigerant total loss (due to leakage) top off the oil in the compressor, adding approximately 130 ml (4.4 oz) of oil. 6. Check screw torque and belt tensioning yearly.
