[4] CHECKING/CLEANING FUEL PRE-FILTER
• The fuel pre-filter has fuel (diesel fuel) inside. Be extremely careful of fire such as
cigarettes when cleaning the fuel pre-filter.
• If the fuel spills when the fuel pre-filter is removed, thoroughly wipe it off.
CAUTION
• Water or dust accumulated inside the fuel pre-filter will cause engine failure. Check
inside the pot and remove any water or dust accumulated inside.
• If water accumulates in the fuel pre-filter, it is assumed that water is also mixed in the
fuel tank. See “INSPECTION AND MAINTENANCE 9.6 EVERY 50 HOURS
MAINTENANCE” to remove the water or dust inside the fuel tank.
1. Place the machine on a level surface.
2. See “OPERATION 1.8 RADIATOR COVER” and remove
the radiator cover.
3. Check the fuel pre-filter (1) for any water or dust that is
accumulated inside and verify if the red float (2) in the
pot has not come up from the bottom.
The red float (2) in the fuel pre-filter (1) coming up
indicates that the water has mixed in.
4. If there is water accumulated in the fuel pre-filter (1),
remove it using the following procedure.
(1) Connect a hose (A) to the outlet of the valve (3) at
the bottom of the fuel pre-filter (1) and then connect
it to the container (B) collecting the drained fuel.
(2) Turn the valve at the bottom of the pot (1) to the left
to loosen and drain the fuel until the red float (2)
inside the fuel pre-filter (1) sinks to the bottom.
(3) When draining is finished, turn the valve (3) at the
bottom of the fuel pre-filter (1) to the right to close.
(4) Disconnect the hose (A) connected to the outlet of
the valve (3).
5. See “OPERATION 1.8 RADIATOR COVER” and remove
the radiator cover.
