135 Hour Maintenance
Hard starting or a gradual loss of
performance can be caused by carbon
deposits lodged in the spark arrester
screen, muffler or cylinder exhaust port.
For maximum performance, the muffler
and spark arrester screen should be
periodically cleaned as follows:
1. Remove the spark plug.
2. Remove (3) self-tapping screws and
(2) machine screws from the engine
cover, and then gently move the
engine cover aside.
3. Remove the (3) spark arrester
retaining screws, then remove the
spark arrester cover, screen, gasket,
and chamber.
4. Use a plastic scraper or wire brush to
remove carbon deposits from
the arrester screen, chamber,
and cover.
WARNING!
Never operate the unit with a
damaged or missing muffler or spark
arrester! Operating with missing or
damaged exhaust components is a
fire hazard and could also damage
your hearing.
5. Inspect the screen carefully, and
replace any screen that has been
perforated, distorted, or is otherwise
unserviceable.

6. Remove the (2) socket-head cap
screws and (1) Phillips head screw,
then remove the muffler.
7. Gently tap the muffler on a wood
surface to dislodge any loose carbon.
8. Inspect the cylinder exhaust port
for excessive carbon buildup
If carbon deposits are severe or if no
performance improvement is noted,
your EB240S blower should be in-
spected by an authorized Shindiawa
servicing dealer.
9. Reinstall the muffler in the reverse
order as described in step 6 and
securely tighten the (2) socket- head
cap screws and Phillips
head screw.
10. Install the chamber, screen, gasket
and cover in the reverse order of
disassembly, and then install and
securely tighten the (3) cover
retaining screws.

Storage
(30 days or longer)
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
starting, 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 thor-
oughly with soap and water. Let dry
and reassemble the element.
■ Store the unit in a clean, dust-free
area.
