4.. Slide hose clamps onto ends of fuel lines. Push fuel
lines onto fuel filter and secure them with hose clamps.

Because diesel fuel is flammable, use
caution 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
starting the engine. Store fuel in a clean,
safety-approved container and keep cap
in place. Use diesel fuel for the engine
only; not for any other purpose.
