Maintenance (continued)
50 Hour Maintenance
Perform more frequently in dusty or
dirty conditions.
Remove and clean the cylinder cover
and clean grass and dirt from the cyl-
inder fins.
Remove the cutting attachment, cut-
ting attachment holder and gear shaft
collar. Remove the filler plug from
the side of the gearcase and press
new grease into the gearcase until old
grease is pushed out. Use only lith-
ium-base grease such as Shindaiwa
Gearcase Lubricant or equivalent.
Fuel Filter Maintenance
Use a hooked wire to extract the fuel
filter from inside the fuel tank.
Remove 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.

Remove the four 4 mm engine cover
screws (two in the back and two in the
front of the cover) and lift the cover
from the engine.

the muffler assembly from the engine.
