COOLING SYSTEM
2. Fill the cooling system slowly. This allows more air to escape and the system to be filled to its
maximum capacity. Fill the system until the coolant fills completely the sight gauge (Fig. 5.8),
approximately 43 [mm] above the inner baffle in the radiator top tank.
3. Install the radiator cap. Start the engine and run until the normal operating temperature is
reached. Check for leaks and add coolant to the proper level.

Fig. 5.10. Fan
WARNING! Keep clear of fan and fan belts when engine is running. Rotating fan
and belt contact can cause injury.
1. Check the condition of the fan blades (cracks, damaged, rivets, loose mounting bolts) and
bearing of the idler pulley.
2. Reversible fan blades (if equipped) should be reversed periodically to clean the radiator and
engine compartment. After reversing the blades adjust them in the required position.
5.10. ELECTRIC SYSTEM
5.10.1. ELECTRIC WIRES AND CONNECTIONS
WARNING! Before working on an engine or electric system, turn off the electric
system master switch and remove the key. All terminals must be clean and
fastened securely. Replace frayed, cracked, and poorly insulated wiring. Electric
system shall not be tampered with. Wrongly made alterations may cause
machine damage or fire.
The surface under all terminals must be clean, and good electrical connections must be
established after any reassembly. Also, all clips must grip cables tightly to prevent vibrations and
rapid cable wear. All clips and straps must be closed in a workmanlike manner, so as not to
damage the insulation.
