50-Hour Maintenance
Every 50 hours of operation (more
frequently in dusty or dirty conditions):
 Remove the cylinder cover and clean
grass and dirt from the cover and cylin-
der fins.
 Remove the cutting attachment, cutting
attachment holder and gear shaft collar.
Remove the filler plug from the side
of the gearcase and press new grease
into the gearcase until grease is pushed
out. Use only lithium-base grease such
as Shindaiwa Gear Case Lubricant or
equivalent. See figure 0.

 Use a hooked wire to extract the fuel filter
from inside the fuel tank. See figure 1.
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.

Clean the
spark plug and
check the gap
at the electrode.
Remove and replace the filter element.
Before reinstalling the new filter ele-
ment, 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.

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:
Every 10 to 15 hours of operation:
 Remove and clean the spark plug. Adjust
the spark plug electrode gap to 0.04
0.08 inch (0.6-0.7 mm). If the spark
plug must be replaced, use only an
NGK BPMR6A or equivalent resistor
type spark plug of the correct heat
range. See Figure 19.
NOTE:
BPMR6A
The NGK also meets the require-
ments for electro magnetic compliance (EMC).
CAUTION!
Before removing the spark plug, clean
the area around the plug to prevent
dirt and debris from getting into the
engine's internal parts.

Figure 22
1. Loosen the gearcase clamp screw.
. Remove the gearcase index screw.
. Slide the gearcase and shield assembly
from the shaft tube.
4. Pull the flexible shaft from the shaft tube
assembly, and clean the shaft thorough-
ly in solvent.
5. Inspect the shaft carefully, and replace
if worn or damaged. If flexible shaft
is worn and needs replacement, liner
should also be replaced.
6. Coat the entire length of the shaft with
Shindaiwa Premium Gearcase Lube (or
equivalent), and reinstall the shaft in the
shaft tube assembly.
NOTE:
For extended shaft life, the flexible cable
should be reversed end-for-end during the
reinstallation process.
7. Insert the flexible shaft into the female
end of the gearcase pinion.
8. Install the gearcase on the shaft tube in
the reverse order of removal.
