IMPORTANT!

All stored fuels should be stabilized  with 

a fuel stabilizer such as STA-BIL™,  if 

Shindaiwa 

 oil with fuel stabilizer is 

not used.

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.
Drain all the fuel from the fuel tank. 

Remove the remaining fuel from the 

fuel lines and carburetor. To do so:

fuel is passing through.
Start and run the engine until it stops 

running.
Repeat steps  and  until the engine

CAUTION!
Gasoline stored in the carbure-
tor for extended periods can cause 
hard starting and could also lead  
to increased service and mainte-
nance cost.

Spark Arrester Maintenance

Hard starting or a gradual loss of performance 

can be caused by carbon deposits lodged in 

the spark arrester screen. For maximum per-

formance, the spark arrester screen should be 

periodically cleaned as follows.

Remove engine cover to expose muf-

fler. Remove the spark arrester from 

the muffler. The arrester is press-fit in 

place; there are three screws to remove.

.

Use a plastic scraper or wire brush 

to remove carbon deposits from 

the arrester screen and wipe clean 

exhaust base. 
Inspect the screen carefully, and 

replace any screen that has been per-

forated, distorted, or is otherwise 

unserviceable. 
Press the spark arrester into the 

exhaust base. 

If carbon accumulation in the muffler 

or cylinder are severe, or if you do not 

notice an improvement in performance 

after servicing, have the unit inspected by 

an authorized servicing Shindaiwa dealer.

WARNING! 
Never operate this unit with 

a damaged or missing muffler or 
spark arrester! Operating with miss-
ing or damaged exhaust components 

is a fire hazard, and can also dam-
age your hearing!

Remove the spark plug and pour about 

/4 ounce of -cycle mixing oil into the 

cylinder through the spark plug hole. 

Slowly pull the recoil starter  or 3 

times so oil will evenly coat the interior 

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 thoroughly 

with soap and water. Let dry and reas-

semble the element.
Remove the drain plug and drain all water 

from the pump housing.  See Figure 0.
Store the unit in a clean, dust-free area.
