Muffler Maintenance
WARNING!
Never operate the unit with
a damage or missing muffler or spark
arrester! Operating with a missing or
damaged spark arrester is a fire hazard
and could also damage your hearing.
Hard starting or a gradual loss of perfor-
mance can be caused by carbon deposits
lodged in the muffler’s spark arrester
screen.
In such cases, performance can usually be
restored by removing the spark arrester
screen and giving it a thorough cleaning
with a stiff bristle brush.
If carbon deposits are severe or if no per-
formance improvement is noted, your unit
should be returned to your Shindaiwa
dealer for inspection.
Long Term Storage
Whenever the unit will not be used for 30
days or longer, use the following proce-
dures to prepare it for storage:
Clean external parts thoroughly and
■
apply a light coating of oil to all metal
surfaces.
Drain all the fuel from the carburetor
■
and the fuel tank.
To do so:
Prime the primer bulb until no more 1.
fuel is passing through.
Start and run the engine until it stops
2.
running.
Repeat steps 1 and 2 until the engine
3.
will no longer start.
Remove the spark plug and pour
■
about 1/4 oz. of engine oil into the
cylinder through the spark plug hole.
Slowly pull the recoil starter 2 or 3
times so oil will evenly coat the inte-
rior of the engine. Reinstall the spark
plug.
Before storing the unit, repair or
■
replace any worn or damaged parts.
Remove the air cleaner element from
■
the carburetor and clean it thor-
oughly with soap and water. Let dry
and reassemble the element.
Store the unit in a clean, dust-free
■
area.
CAUTION!
Gasoline stored in the carbure-
tor for extended periods can cause
hard starting, and could also lead to
increased service and maintenance
costs.
IMPORTANT!
All stored fuels should be stabilized with
a fuel stabilizer such as STA-BIL™.
NOTE
Damage resulting from stale or con-
taminated fuel is not covered by the
Shindaiwa warranty policy.
