Spark Arrester Maintenance

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!

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.

3.Inspect the screen carefully, and replace any screen that has been per- forated, distorted, or is otherwise unserviceable.

4.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.

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:

. Prime the primer bulb until no more fuel is passing through.

. Start and run the engine until it stops running.

3.Repeat steps 1 and 2 until the engine will no longer start.

IMPORTANT!

All stored fuels should be stabilized with a fuel stabilizer such as STA-BIL™, if

Shindaiwa

oil with fuel stabilizer is

not used.

 

 

 

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 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 20.

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 mainte- nance cost.
