CAUTION!

Make sure you do not pierce the fuel

line with the end of the hooked wire.

The line is delicate and can be dam

aged easily.

Remove and replace the fuel lter

element.

■ Use a hooked wire to extract the

fuel lter from inside the fuel tank.

Inspect the fuel lter element. If it

shows signs of contamination from

debris, replace it with a genuine

Shindaiwa replacement fuel lter

element.

135 hour maintenance

■ Combustion chamber should be

decarbonized, and the valve clear-

ance should be adjusted. It is highly

recommended that this is done

by a Shindaiwa-trained service

technician.

Maintenance (continued)

6. Turn engine over several times, and

return to TDC-compression. Recheck

with proper feeler gauge to make

sure clearance adjustment 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.

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

compression stroke (TDC), the valves

can be adjusted.

2. Loosen adjuster locknut so that the

2.5 mm Allen socket head adjustment

screw can turn freely.

3. Insert 0.10 mm (0.004”) feeler gauge

between valve stem tip and rocker

arm.

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.

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.

50-Hour Maintenance

NOTE:

Federal EPA regulations require all model year 2012 and later gasoline powered

engines produced for sale in the United States to be equipped with a special low

permeation fuel supply hose between the carburetor and fuel tank. When servic-

ing model year 2012 and later equipment, only fuel supply hoses certied by EPA

can be used to replace the original equipment supply hose. Fines up to $37,500

may be enforced for using an un-certied replacement part.

IMPORTANT!

If a new gasket is not available and/

or the old gasket is not damaged, the

old gasket may be reused. Never use

cracked or damaged gaskets!
