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 rust damage.
Apply a thin coat of rust preventive
oil to all metal parts.
2. FUEL:
To protect the fuel tank during storage, fill the
tank with gasoline that has been treated with
a fuel stabilizer additive. Follow fuel stabilizer
manufacturer’s recommendations for use. Refer
to Checking and Filling Fuel on page 8.
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.
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.
NOTICE: During extended storage periods the
Engine must be started every 3 months and allowed
to run for 15 – 20 minutes or the Warranty is VOID.
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.
