BLEEDING
MI 15 D / MI 18 D

MI 30 D / MI 35 D
These operations are to be carried out only in the following cases:
- A component of the fuel system replaced or drained.
- A drained tank.
- Running out of fuel.
NOTE: Ensure that the level of fuel in the tank is sufficient.
Perform bleeding in the following order:
BLEEDING FROM THE FUEL FILTER
- Raise the engine cover (see: 2 - DESCRIPTION: INSTRUMENTS AND CONTROLS).
- Check the presence of diesel in pre-filter 1 (fig. G1/1).
- Activate feed pump 2 (fig. G1/1) until the diesel fuel flows out free from air at the bleed screw
3 (fig. G1/1).
BLEEDING FROM THE INJECTORS
- Loosen the high pressure connectors 4 (fig. G1/2) of all the injectors.
- Activate the starter until the diesel fuel flows out free of air at high pressure connectors 4
(fig. G1/2).
Do not engage the starter motor on a continual basis for more than 30 seconds and let it cool between
unsuccessful attempts.
- Tighten the connections while the diesel fuel is flowing out ( tightening torque 30N.m ).
- So the engine is ready to be started up.
- Turn the engine over slowly for 5 minutes immediately after bleeding the fuel feed circuit, in
order to ensure that the injection pump has been bled thoroughly.
NOTE: If the engine functions correctly for a short time then stops or functions irregularly, check for possible leaks in the low pressure
circuit. If in doubt, contact your dealer.
