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 & 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 0.024 - 0.028 inch (0.6 - 0.7 mm).
Clean spark plug once a week.
4. Muffler – Used to reduce noise and emissions.
5. Recoil Starter (pull rope) – Manual-starting method.
Pull the starter grip until resistance is felt, then pull
briskly and smoothly.
6. Engine ON/OFF Switch – Controls the starting and
stopping of the engine. Switch must be in the "ON"
position when starting the engine.
BASIC ENGINE
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.
NOTICE
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.
