Fuel
Dirt and water in the fuel can
damage the engine. Remove
dirt and debris from the fuel
tank. Before filling the fuel tank,
make sure that the fuel and
filling equipment is clean and
free of debris. Avoid using fuel containers
made of zinc plated steel. A plastic or
stainless container is recommended.
1. Fill the fuel tank with fresh fuel.
Tank capacity: 7.4 gal (28L).
2. If the floating red ring rises from the
bottom of the water separator, turn the
fuel shut-off valve to the OFF (closed)
position, then loosen the drain valve
and drain until the floating red ring
returns to the bottom.
DAILY CHECK ITEMS
Coolant
Check the coolant level of the reservoir
tank. It should be between the upper and
lower limits marked on it when the engine
is warm. If the engine is cold, the coolant
level must be at the low line on the reserve
tank. When necessary, add a pre-diluted
coolant with an antifreeze to water ratio
that suits the local climate*.
