Bleed Fuel System
1. Park machine on a level surface, lower cutting units,
stop engine, and engage parking brake.
2. Make sure fuel tank is at least half full. Gain access

DANGER
Because diesel fuel is highly flammable, use cau-
tion when storing or handling it. Do not smoke
while filling the fuel tank. Do not fill fuel tank
while engine is running, hot, or when machine is
in an enclosed area. Always fill fuel tank outside
and wipe up any spilled diesel fuel before start-
ing the engine. Store fuel in a clean, safety-ap-
proved container and keep cap in place. Use die-
sel fuel for the engine only; not for any other pur-
pose.
3. Loosen air bleed screw on the top of the fuel filter/wa-
ter separator (Fig. 9).
4. Pump lever on the fuel pump (Fig. 10) until a solid
stream of fuel flows out around the bleed screw on the
fuel filter/water separator. Tighten air bleed screw.
5. Open air bleed screw on the fuel injection pump with
a 12 mm wrench (Fig. 11).
6. Pump lever on fuel pump (Fig. 10) until a solid stream
of fuel flows out around screw on the fuel injection pump.

However, if the engine does not start, air may be
trapped between injection pump and injectors (see
