Figure 4. Basic Engine Components
INITIAL SERVICING
The engine (Figure 4) must be checked for proper
lubrication and filled with fuel prior to operation. Refer to
the manufacturer's engine manual for detailed operation
and service instructions.
1. Throttle Lever — Adjusts engine speed (RPM).
2. Fuel Filler Cap — Remove to add unleaded gasoline to
the fuel tank. Make sure the cap is tightened securely.
DO NOT overfill.
DANGER
NEVER fill the fuel tank while the engine
is running or hot. In the event of a fuel
spill, DO NOT start the engine until all
fuel residue has been wiped up and the
area surrounding the engine is dry. Fuel
is extremely flammable and can ignite if
it comes into contact with hot engine parts
or sparks from the ignition system.
3. Fuel Tank — Holds up to 3.3 quarts (3.6 liters) of
unleaded gasoline. Refer to the manufacturer's engine
manual for additional information.
4. Engine ON/OFF Switch — ON position permits engine
starting, OFF position stops engine operation.

5. Recoil Starter — Manual starting mechanism. Pull
the starter grip slowly until resistance is felt, then pull
briskly and smoothly to start the engine.
6. Fuel Valve Lever — Open to allow the flow of fuel, and
4
close to prevent the flow of fuel.
7. Oil Drain Bolt — Remove to drain oil from the
engine crankcase.
8. Dipstick/Oil Filler Cap — Remove to determine
if engine oil is low. Add oil through this port as
recommended in Table 5.
9. Choke Lever — Aids in starting a cold engine or
starting in cold weather conditions. The choke enriches
the fuel mixture.
10. Spark Plug — Provides spark to the ignition system.
Set the spark plug gap according to the engine
manufacturer's instructions, and clean the spark plug
once a week.
11. Muffler — Reduces noise and emissions. NEVER
touch the muffler while it is hot.
WARNING
12. Air Cleaner — Prevents dirt and other debris from
entering the fuel system. Remove the wing nut on top
of the air cleaner to gain access to the filter elements.
NOTICE
Operating the engine without an air filter, or with a
damaged or worn air 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, NEVER
touch these areas while the engine is
running or immediately after operating.
NEVER operate the engine with the
muffler removed.
