50-hour Maintenance
Every 50 hours of operation
(more frequently in dusty or dirty
conditions):
n Remove and clean the cylinder cover
and clean grass and dirt from the cylin-
der fins.
n Remove the cutting attachment, cutting
attachment holder and gear shaft collar.
Remove the filler plug from the side of
the gear case and press new grease into
the gear case until old grease is pushed
out. Use only lithium-base grease such
as Shindaiwa Gear Case Lubricant or
equivalent. See Figure 28.
n Lubricate main shaft splines.
n Use a hooked wire to extract the fuel
filter from inside the fuel tank.
See Figure 29.

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.
Every 10 to 15 hours
of operation:
Remove and clean the spark plug. Adjust
the spark plug electrode gap to 0.024 - 0.028
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 27.
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.
10/15-Hour Maintenance
Remove and replace the 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 deteriora-
tion is noted, the unit should be removed
from service until it can be inspected or
repaired by a Shindaiwa-trained service
technician.
