Maintenance (continued)

Valve Adjustment

1.Remove cylinder cover, rocker arm cover, and spark plug. Rotate the crankshaft while observing the piston through the spark plug opening. When the piston is at the top of the compres- sion stroke (TDC), the valves can be adjusted.

CAUTION!

■■Performing a valve adjustment incorrectly may cause hard starting and/or can damage the engine.

■■If you are unfamiliar with this engine or uncomfortable with this procedure, consult with an authorized Shindaiwa servicing dealer.

4.Turn adjustment screw (clockwise = tighter, counter-clockwise = looser) until feeler gauge is almost snug.

Back off just enough to allow gauge to slip out with limited resistance.

5.While holding the adjustment screw in place with the Allen driver, tighten the locknut with a wrench.

6.Turn engine over several times, and returnthe to TDC-compression. Recheck with proper feeler gauge to make sure clearance adjust- ment did not change as a result of tightening the locknut. Readjust as necessary.

7.Replace rocker arm cover gasket to assure proper sealing and install cover.

Spark Arrester Maintenance

WARNING!

Never operate this unit

with a damaged or missing muffler

or spark arrester! Operating with missing or damaged exhaust com-

ponents is a fire hazard, and can

also damage your hearing!

Hard starting or a gradual loss of perfor- mance can be caused by carbon deposits lodged in the spark arrester screen. For maximum performance, the spark arrester screen should be periodically cleaned as follows.

1.Remove engine cover to expose muffler. Remove the spark arrester from the muffler. The arrester is press-fit in place; there are three screws to remove.

2.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 perforated, 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.
