Initial Servicing
The engine (Figure 6) 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 Filler Cap – Remove this cap to add unleaded
gasoline to the fuel tank. Make sure cap is tightened
securely. DO NOT over fill.
5. Fuel Valve Lever – OPEN to let fuel flow, CLOSE to
stop the flow of fuel.
6. Choke Lever – Used in the starting of a cold engine, or
in cold weather conditions. The choke enriches the fuel
mixture.
7. 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.
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.
