5. DRAINING AND FILLING

5.1 TOPPING UP BATTERY FLUID

Avoid sparks and open flames in the

vicinity of batteries. Battery acid is

an aggressive fluid.

In the event of contact with the skin:

rinse the skin with plenty of water for

a sustained period. If redness or

pain persists, consult a doctor.

Remove any clothing affected and

rinse with water.

In the event of contact with the eyes:

rinse with plenty of water for at least

15 minutes and consult a doctor.

If swallowed: do NOT induce

vomiting. Rinse the mouth, drink two

glasses of water and consult a

doctor.

In the event of inhalation: get fresh

air, rest and consult a doctor.

Topping up battery fluid
1.

Clean the top of the battery. If the top of the

battery has acid on it, it should be rinsed with

water.

2.

Remove the plugs and top up the batteries

with distilled water to approximately 10 mm

above the plates or up to the "max" indicator

level.

5.3 DRAINING, FILLING AND BLEEDING THE COOLING SYSTEM

In order to avoid damaging the

cylinder block, do not top up a warm

engine with cold coolant. Coolant is

a toxic fluid and must be handled

with care. Protect skin and eyes.

Coolant is harmful to the

environment; after use, it should be

processed as industrial chemical

waste. When the coolant is hot, there

is overpressure in the cooling

system. When removing the filler

cap, allow the overpressure to

escape by first loosening the filler

cap one turn.

Draining the cooling system
1.

Turn the heater temperature control knob in

the cab to the "warmest" setting.

2.

Remove the cooling system filler cap.

3.

Collect the coolant. Position suitable

containers under the drain points.

4.

Drain the cooling system at the radiator via

the drain plug.

5.

Flush the cooling system.

6.

Close the drain plug.

Filling and bleeding cooling system
1.

Turn the heater temperature control knob in

the cab to the "warmest" setting.

2.

Fill the cooling system with the specified

coolant.

3.

Run the engine for several minutes.

4.

The cooling system is auto-bleeding.

Ensure that the air bleed pipe from the

thermostat housing to the header tank is not

twisted or pinched.

Note:

Make sure that air can escape when the

cooling system is filled.

5.

Check the coolant level, and top up with

coolant if necessary.
