4. When installing a new spark plug, adjust
the plug’s gap to the specication on the
Specications chart. Do not pry against the
electrode, the spark plug can be damaged.
5. Install the new spark plug or the cleaned spark plug
into the engine. Gasket-style: Finger-tighten until the
gasket contacts the cylinder head, then about 1/2-2/3
turn more.
Non-gasket-style: Finger-tighten until the plug
contacts the head, then about 1/16 turn more.
NOTICE: Tighten the spark plug properly.
If loose, the spark plug will cause the engine
to overheat. If overtightened, the threads
in the engine block will be damaged.

Storage
When the equipment is to remain idle for longer than
20 days, prepare the engine for storage as follows:
1. CLEANING:
Wait for engine to cool, then clean engine with
dry cloth. NOTICE: Do not clean using water.
Water will gradually enter engine and cause rust
damage.
Apply a thin coat of rust preventive
oil to all metal parts.
2. FUEL:
WARNING! TO PREVENT SERIOUS
INJURY FROM FIRE:
Drain the fuel tank in a well-ventilated area
away from ignition sources. If the engine is
hot from use, shut the engine off and wait
for it to cool before draining fuel.
Do not smoke.
a. Place a funnel leading to a proper gasoline
container below the carburetor.
b.
Drain Plug
Remove the drain bolt from the bottom of the
carburetor bowl and allow the fuel to drain.
c. After all fuel has drained, reinstall the
drain bolt. Tighten securely.
3. LUBRICATION:
a. Change engine oil.
b. Clean out area around spark plug. Remove
spark plug and pour one tablespoon of engine
oil into cylinder through spark plug hole.
c. Replace spark plug, but leave spark
plug cap disconnected.
d. Pull Starter Handle to distribute oil in cylinder.
Stop after one or two revolutions when you
feel the piston start the compression stroke
(when you start to feel resistance).
4. STORAGE AREA:
Cover and store in a dry, level, well-ventilated
area out of reach of children. Storage area
should also be away from ignition sources, such
as water heaters, clothes dryers, and furnaces.
5. AFTER STORAGE:
Before starting the engine after storage, keep
in mind that untreated gasoline will deteriorate
quickly. Drain the fuel tank and change to fresh
fuel if untreated gasoline has been sitting for
a month, if treated gasoline has been sitting
beyond the fuel stabilizer’s recommended time
period, or if the engine does not start properly.
