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 or hot, or when machine
is in an enclosed area. Always fill fuel tank out-
side 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.
