WARNING!
Never operate the unit with a damaged
or missing mufer or spark arrester!
Operating with missing or damaged ex-
haust components is a re hazard and
could also damage your hearing.
6. Inspect the cylinder exhaust port for
carbon buildup.
IMPORTANT!
If you note excessive carbon buildup, con-
sult with an authorized servicing dealer.
7. Reassemble the muffler in the reverse
order of disassembly.
Long Term Storage
whenever the unit will not be used
for 30 days or longer, use the following
procedures to prepare it for storage:
Clean external parts thoroughly.
Drain all the fuel from the fuel tank.
IMPORTANT!
All stored fuels should be stabilized with
a fuel stabilizer such as STA-BIL™ if
Shindaiwa One oil with fuel stabilizer is
not used.
To remove the remaining fuel from the
fuel lines and carburetor with the fuel
drained from the tank;
1. Prime the primer bulb until no more fuel
is passing through the return tube.
2. Start and run the engine until it stops
running.
3. Repeat steps 1 and 2 until the engine will
no longer start.
CAUTION!
Gasoline stored in the carburetor for
extended periods can cause hard start-
ing, and could also lead to increased
service and maintenance costs.
Remove the spark plug and pour about
1/4 ounce of 2-cycle mixing oil into the
cylinder through the spark plug hole.
Slowly pull the recoil starter 2 or 3 times
so oil will evenly coat the interior of the
engine. Reinstall the spark plug.
Before storing the machine, repair or
replace any worn or damaged parts.
Remove the air cleaner element from the
carburetor and clean it thoroughly with
soap and water. Let dry and reassemble
the element.
Store the machine in a clean, dust-free
area.
