INITIAL SERVICING
The engine (Figure 7) 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. The
engine shown above is a HONDA engine, operation for other
types of engines may vary somewhat.
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.
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.
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.
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.
10. Fuel Tank – Holds unleaded gasoline. For additional
information refer to engine owner's manual.

DANGER

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.

WARNING

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. Throttle Lever – Used to adjust engine RPM speed (lever

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.
5. Fuel Valve Lever – OPEN to let fuel flow, CLOSE to stop
the flow of fuel.
