Bleeding the Fuel System

You must bleed the fuel system before starting the
engine if any of the following have occurred:
•
Initial start up of a new machine
•
The engine has ceased running due to lack of fuel.
•
Maintenance has been performed upon fuel
system components (i.e., filter replaced, separator
serviced, etc.)
1. Perform the pre-maintenance procedure; refer
to Checking the Tire Pressure (page 45)
ensure that the fuel tank is at least half full.
2. Open the hood and secure it with the prop rod.
3. Open the air-bleed screw on the fuel-injection
pump (Figure 35) with a 12 mm wrench.

4. Turn the key in the ignition switch to the O
position. The electric fuel pump will begin
operation, thereby forcing air out around the air
bleed screw. Leave the key in the O
until a solid stream of fuel flows out around the
screw.
5. Tighten the screw and turn the key to the O
position.
Note:
The engine should start after you perform this
procedure. However, if engine does not start, air may
be trapped between injection pump and the injectors;
