Maintenance (continued)

Remove the shaft bolt, bolt guard,

holder A, blade, holder B, and

the output shaft collar. Press new

grease into the gearcase until the

old grease has been pushed out.

Use only lithium-base grease.

Lubricate the Flexible Shaft

Lack of lubrication will cause rapid

wear to the flexible shaft and also

to the shaft tube liner, resulting

in increased vibration and greatly

decreased service life. Remove and

lubricate the flexible shaft as follows:
1. Loosen the gearcase clamp screw.
2. Remove the gearcase index screw.
3. Slide the gearcase and shield

assembly from the shaft tube.

4. Pull the flexible shaft from the shaft

tube assembly, and clean the shaft

thoroughly in solvent.

5. Inspect the shaft carefully, and

replace if worn or damaged. If flexi-

ble shaft is worn and needs replace-

ment, liner should also be replaced.

6. Coat the entire length of the shaft

with a premium gearcase lube and

reinstall the shaft in the shaft tube

assembly.

7. Insert the flexible shaft into the

female end of the gearcase pinion.

NOTE:

For extended shaft life, the flexible

cable should be reversed end-for-end

during the reinstallation process.

50 Hour Maintenance

Remove and replace the fuel filter

element.

Use a hooked wire to extract the fuel filter from

inside the fuel tank. Inspect the fuel filter ele-

ment. If it shows signs of contamination, replace

with a genuine Shindaiwa replacement fuel filter

element.

Before reinstalling the new filter element, inspect

the condition of all the fuel system components

(fuel pick-up line, fuel return line, tank vent line,

tank vent, fuel cap and fuel tank).

If damage, splitting or deterioration is noted, the

unit should be removed from service until it can

be inspected or repaired by a Shindaiwa-trained

service technician.

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.

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 certified by EPA

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

may be enforced for using an un-certified replacement part.
