DANGER

Adding fuel to the tank should be done only when
the engine is stopped and has had an opportunity
to cool down. In the event of a fuel spill, DO NOT attempt to start the
engine until the fuel residue has been completely wiped up, and the
area surrounding the engine is dry.
2. Fuel Tank – Diesel engine holds 5.8 quarts of diesel fuel.
3. Air Cleaner – Prevents dirt and other debris from entering
the fuel system. Remove wing-nut on top of air filter
cannister to gain access to filter element.
Operating the engine without
an air filter, with a damaged air
filter, or a filter in need of
replacement will allow dirt to
enter the engine, causing rapid
engine wear.

Engine components can generate extreme heat.
To prevent burns, DO NOT touch these areas
while the engine is running or immediately after operating. NEVER
operate the engine with the muffler removed.
