Bleed Fuel System; Bleed Air From Fuel Injectors - Toro Reelmaster 3100-D Service Manual

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
to the engine.
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. Open air bleed screw on the fuel injection pump.
IMPORTANT: The engine should normally start af-
ter the above bleeding procedures are followed.
However, if the engine does not start, air may be
trapped between injection pump and injectors (see

Bleed Air from Fuel Injectors).

Bleed Air from Fuel Injectors
IMPORTANT: This procedure should be used only if
the fuel system has been purged of air through nor-
mal priming procedures (see Bleed Fuel System)
and engine will not start.
