Diesel Engine: Service and Repairs
Diesel fuel is highly flammable and explosive. A fire or an explosion
from the fuel can burn you, burn other people, and damage property.
• Use caution whenever you store or handle diesel fuel.
• Do not smoke while filling the fuel tank.
• Do not fill the fuel tank while the engine is running, while the
engine is hot, or when the machine is in an enclosed area.
• Always fill the fuel tank outside and wipe up any spilled diesel
fuel before starting the engine.
• Store fuel in a clean, safety-approved container and keep the cap
in place.
• Use diesel fuel as an engine fuel only, not for any other purpose.
Check the fuel lines and connections at the scheduled maintenance intervals
recommended in the Operator's Manual. Check the lines for deterioration,
damage, leaks, or loose connections. Replace the hoses, clamps, and fittings
as necessary.
Drain and clean the fuel tank at the maintenance intervals recommended in the
Operator's Manual. If the fuel system becomes dirty or if the machine is stored
for an extended period, drain and clean the fuel tank.
To clean the fuel tank, flush the tank out with clean diesel fuel. Ensure that the
fuel tank is free of contamination and debris.
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 a fuel hose). To prime the fuel
system, ensure that the fuel tank has fuel in it. Then, turn the key switch to the
R position for 10 to 15 seconds, which allows the fuel pump to prime the fuel
