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.
