The engine (Figure 2) must be checked for proper
lubrication and filled with fuel prior to operation. Refer
to the manufacturer's engine manual for instructions and
details of operation and servicing.
1. Secondary 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.
2. Choke Lever — Used when starting the engine.
Normally used in cold weather conditions. In cold
weather turn the choke lever to the fully closed
position, in warm weather set choke lever half way or
completely open.
3. Spark Plug — Provides spark to the ignition system.
Set spark plug gap to 0.02 - 0.03 inch (0.6 - 0.7 mm).
Clean spark plug once a week.
4. Engine ON/OFF Switch — Controls the starting and
stopping of the engine. Switch must be in the "ON"
position when starting the engine.
5. Recoil Starter (pull rope) — Manual-starting method.
Pull the starter grip until resistance is felt, then pull
briskly and smoothly.
6. Muffler — Used to reduce noise and emissions.
NOTICE
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
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.
