Checks Before Starting 3
Always check the items in this section before starting the engine each day.
Check Coolant Level, Add Coolant
WARNING
q
Do not open the radiator cap unless necessary. When checking the coolant, always wait for the
engine to cool down and check the sub tank.
q
Immediately after the engine is stopped, the coolant is at a high temperature and the radiator is under
high internal pressure. If the cap is removed to check the coolant level in this condition, there is a
hazard of burns. Wait for the temperature to go down, then turn the cap slowly to release the pressure
and remove it carefully.
1. Open the right rear cover on the machine and check that
the cooling water level is between the FULL and LOW
marks on radiator sub tank (1) (shown in the diagram on
the right).
If the water level is low, add water through the water filler of
sub tank (1) to the FULL level.
2. After adding coolant, tighten the cap securely.
3. If the sub-tank (1) is empty, there is probably leakage of
coolant. After inspecting, repair any problem immediately. If
there is no problem, check the coolant level in the radiator.
If the coolant level is low, add coolant to the radiator, then
fill the sub-tank (1).
Drain Water And Sediment from Fuel Tank
1. Open the door at the right of the machine.
2. Set a container under the drain hose to catch the drained
fuel.
3. Open drain valve (1) and drain the water and sediment
accumulated at the bottom together with the fuel.
4. When no more water and sediment comes out with the
fuel, close drain valve (1).
5. Close the door.
