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.
Drain Plug
Sediment Cup
(some engines)
Remove the drain bolt from the bottom of the
carburetor bowl and allow the fuel to drain.
c. Remove the small sediment cup next to the bowl
and allow the fuel to drain from there as well.
d. 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.
