Priming the Fuel System
Removing and Installing the Fuel Tank
Engine: Service and Repairs
The fuel system needs to be primed before starting the engine for the first time,
after running out of fuel, or after fuel system maintenance (e.g., draining the
fuel/water separator, replacing the fuel filter or disconnecting a fuel hose).
Do not turn the key switch to the START position to prime the fuel
system.
To prime the fuel system:
1. Ensure that the fuel tank has fuel in it.
2. Allow the electric fuel pump to prime the fuel system by turning the key
switch to the RUN position for 10 to 15 seconds. Cycle the key switch and
repeat if necessary.
Refer to Figure 15 for this procedure.
1. Park the machine on a level surface, lower the cutting unit (or attachment),
engage the parking brake, set the key switch to the Off position and remove
the key from the key switch.
2. Empty the fuel tank through the filler neck.
3. Open the hood and remove the left side hold down bracket from the ROPS.
4. Remove the battery cover.
5. Remove the cap screw (item 2) from under the front of the fuel tank.
To prevent damage to the fuel hoses, cable ties and clamps may
be used to secure the hoses to the machine components. Record
the location of all cable ties and clamps that are removed from the
machine so they can be properly replaced.
6. Label the fuel hoses for assembly purposes. Loosen the hose clamps and
disconnect the hoses from the fuel tank.
7. Cover or plug the fuel hoses or fitting openings to prevent contamination
from entering the fuel system.
8. Remove the fuel tank from the machine.
9. Inspect the 4 rubber bumpers that support the fuel tank for damage or wear
and replace them if necessary.
10. Inspect the 3 rubber grommets that support the fuel fittings for damage or
wear and replace them if necessary.
11. To install the fuel tank, follow this procedure in reverse order.
12. If the elbow fittings are removed from the fuel/water separator head, apply
thread sealant to the fittings when installing.
