Spark plug Maintenance
1. Disconnect spark plug cap from end of plug.
Clean out debris from around spark plug.
2. Using a spark plug wrench, remove the spark plug.
3. Inspect the spark plug: If the electrode is oily,
clean it using a clean, dry rag. If the electrode
has deposits on it, polish it using emery paper.
If the white insulator is cracked or chipped,
the spark plug needs to be replaced.
nOtice: Using an incorrect spark plug may
damage the engine. See the Specifications chart
for your Generator for the type and gap required.
4. When installing a new spark plug, adjust
the plug's gap to the specification on the
Specifications chart. Do not pry against the
electrode, the spark plug can be damaged.
Long-term 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.
The water will gradually enter the Engine and
cause corrosion damage. Apply a thin coat of
corrosion preventive oil to all metal parts.
2. FueL:
Gasoline treatment/Draining the Fuel tank
To protect the fuel tank during storage, fill the
tank with fresh gasoline that has been treated
with a fuel stabilizer additive. Follow fuel
stabilizer manufacturer's recommendations
for use. Refer to Checking and Filling Fuel
Checking and Filling Fuel on page 11.
Aged gasoline that has not been treated with
stabilizer ahead of time must be safely drained
away and not run through the engine.
WarninG! tO preVent SeriOuS
inJury FrOM Fire:
Fill 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 adding fuel. Do not smoke.
Draining the carburetor
After closing the Fuel Valve, place an appropriate
container under the Carburetor and carefully
remove the Drain Bolt from the bottom of the
Carburetor Bowl, allowing the fuel to drain
completely. Replace the Drain Bolt after draining.
WarninG! to prevent serious
injury and fire, close the Fuel Valve
before draining the carburetor.

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.
6. Apply dielectric spark plug boot protector
(not included) to the end of the spark
plug and reattach the wire 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.
Avoid direct exposure to rain and sunlight.
nOtice: During extended storage periods the
Engine must be started every 3 months and allowed
to run for 15 – 2 0 minutes or the Warranty is VOID.
5. aFter StOraGe:
Before starting the Engine during or 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.
