INITIAL SERVICING
The engine (Figure 6) must be checked for proper lubrication
and filled with fuel prior to operation. Refer to the manufactur-
ers Engine manual for instructions & details of operation and
servicing.
1. Fuel Filler Cap – Remove this cap to add unleaded gaso-
line 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 enter-
ing 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.
DANGER
2. Throttle Lever – Used to adjust engine RPM speed (lever
advanced forward SLOW, lever back toward operator
FAST).
3. Engine ON/OFF Switch – ON position permits engine
starting, OFF position stops engine operations.
4. Recoil Starter (pull rope) – Manual-starting method. Pull
the starter grip until resistance is felt, then pull briskly and
smoothly.
8. Spark Plug – Provides spark to the ignition system. Set
spark plug gap to 0.6 - 0.7 mm (0.028 - 0.031 inch) Clean
spark plug once a week.
9. Muffler – Used to reduce noise and emissions.
10. Fuel Tank – Holds unleaded gasoline. For additional
information refer to engine owner's manual.
