SAFETY OPERATION MAINTENANCESETUP
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 Specications chart 
for your Generator for the type and gap required.
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.
6.  Apply dielectric spark plug boot protector 
(not included) to the end of the spark 
plug and reattach the wire securely.
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 
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.  Remove the 
drain bolt from 
the bottom of 
the carburetor 
bowl and allow 
the fuel to drain.
If present on 
your model, 
remove the small sediment cup next to the bowl 
and allow the fuel to drain from there as well.
c. Open the fuel valve. After all fuel has 
drained, reinstall the drain bolt and sediment 
cup (if equipped). 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.  BATTERY: 
Disconnect battery cables (if equipped). 
Recharge batteries monthly while in storage.
5.  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.
6.  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.
