CAUTION:
1. If the cup is removed without turning the fuel filter lever just
above, the fuel may flow out.
2. The cartridge and cup contain fuel. Take care not to spill it
during disassembly.
3. Perform the "fuel system air bleeding" after the water in the
fuel is drained.
(2) Fuel System Air Bleeding
The entry of air into the fuel system will cause hard engine starting or
engine malfunction.
When once the servicing such as emptying the fuel tank, draining for
the water sedimenter, and the fuel filter element change is done, be
sure to conduct air bleeding.
Because of the "automatic air-bleeding system" being employed, turn
the starter switch to the "Drive" position and activate the
"electromagnetic pump" to bleed the air.
Air bleeding procedure:
1) When the "starter switch" is set to the "Drive" (ON) position to activate
the electromagnetic pump, fuel is forcibly sent to the fuel valve of each
injection pump and further to the leak-off pipe of each nozzle holder,
where air in the fuel leaks off automatically to the fuel tank.
2) Start the engine and check the fuel system for leakage.
CAUTION:
Start the engine and check the fuel system for leakage.
Leakage causes a fire.
