BLEEDING AIR FROM THE
INJECTION SYSTEM
Bleed the injection system to evacuate air contained in the pipes
after changing the fuel filter or after draining the tank.
To bleed the system:
1st case: After changing the fuel filter
1 - Drain range ARES 500.
2 - Drain range ARES 600.
- Loosen bleed screw (A) located on the head of the final filter.
- Activate the feed pump priming lever (B) until all the air is
eliminated.
- Retighten bleed screw (A).
2nd case: After complete draining of the circuit
- Loosen fuel return pipe (C) at the injector pump.
- Operate the fuel feed pump priming lever.
- As soon as the fuel flowing out no longer contains any
bubbles, tighten the fuel return pipe at a torque of 2,7 daN.m.
The priming lever is spring-loaded to the normal position when
released.
- Place the accelerator lever in the mid acceleration position.
Important: Always use the correct spanner to loosen or
tighten the fuel pipes at the injectors and/or injection pump
to avoid damage.
1 - Using 2 spanners, loosen the fuel pipe connections (D) at
the injectors.
2 - Turn the ignition switch on for 15 seconds until fuel flows
without air bubbles from the loosened connector. Tighten up
the connection to a torque of 2,7 daN.m.
3 - Repeat this procedure on the other injectors (if necessary)
until the fuel system is completely free of air.
Note: If there is no resistance in the fuel pump primer lever,
turn the engine using the starter until the pump operating
cam is correctly located on the camshaft. Never turn the
engine without ensuring that there is adequate fuel supply.
If the engine still does not start, consult your approved
CLAAS repairer.
