Loosen the alternator mount bolts. Do not remove them.

Pull the alternator outwards as shown to tension the belt.

Hold the alternator in position and tighten the mount bolts.

Tighten the alternator mount bolts to correct torque value.

Check the belt tension, if necessary repeat the steps from 1 to 4.

CAUTION The cooling system is pressurised when the coolant is hot. When you remove the cap, hot coolant can spray out and burn you. Make sure that the engine is cool before you work on the cooling system.

Carefully loosen the radiator cap. Let any pressure escape before removing the cap.

Check that the coolant level is flush with the top of the filler neck.

Fill with 50% antifreeze and 50% decalcified water until it reaches the correct level and replace the cap.

Top liquid up until the pipes inside the radiator are covered approximatively by the amount specified. Do not overfill the radiator, but leave room for the coolant to expand. Length/Dimension/Distance: 5mm

Run the engine to raise the coolant to working temperature and pressure. Stop the engine, checks for leaks and re-check the fluid level.

Follow all the precautions described below, to prevent damage to the alternator and battery.

2. Make sure that the battery negative terminal is connected to the earth cable.

3. Do not connect or disconnect the battery or alternator connections, or any part of the charging circuit while the engine is in operation. If you disregard this instruction, the regulator or rectifying diodes will be damaged.

4. Main output cables are always in active state of current flow even when the engine is not in operation. If the alternator connector is removed, do not earth the moulded plug.

5. When you do arc welding on the machine, remove the moulded plug (or if the separate output cables are installed, remove the cables) to protect the alternator.

6. If it is necessary to jump start the battery then do the steps below.

6.1. Connect the secondary battery in parallel without disconnecting the vehicle battery from the charging circuit.

Notice: Do not exceed the correct level of engine oil in the sump. If there is too much engine oil, the excess must be drained to the correct level. An excess of engine oil could cause the engine speed to increase rapidly without control.

WARNING Hot oil and engine components can burn you. Make sure the engine is cool before doing this job.

Used engine crankcase lubricants contain harmful contaminants. In laboratory tests it was shown that used engine oils can cause skin cancer.

CAUTION It is illegal to pollute drains, sewers or the ground. Clean up all spilt fluids and/or lubricants.

Used fluids and/or lubricants, filters and contaminated materials must be disposed of in accordance with local regulations. Use authorised waste disposal sites.

Remove the engine oil drain plug. Drain the oil in to a suitable container.
