The engine (Figure 5) must be checked for proper lubrication
and filled with fuel prior to operation. Refer to the
manufacturers engine manual for instructions & details of
operation and servicing.
1. Fuel Tank/Fuel Filler Cap – Holds unleaded gasoline.
For additional information refer to engine owner's
manual. Remove this cap to add unleaded gasoline to
the fuel tank. Make sure cap is tightened securely. DO
NOT over fill.
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.
