10 Hour Maintenance
CAUTION!
Do not operate the machine if the air
cleaner or element is damaged, or if
the element is water-soaked.
Remove the air cleaner element from
the carburetor and clean it thorough-
ly with soap and water. Squeeze out
excess, let dry and reassemble the
element.
10/15 Hour Maintenance
CAUTION!
Before removing the spark plug, clean
the area around the plug to prevent dirt
and dust from getting into the engine’s
internal parts.
Remove and clean the spark plug.
Adjust the spark plug electrode gap
to 0.6 - 0.7mm. If the plug must be
replaced, use only NGK BMR6A.
50 Hour Maintenance
Cleaning
Remove and clean the cylinder cover
and clean grass and dirt from the
cylinder fins.
Remove the cutting attachment and
the gear shaft collar, and press new
grease into the gear case until the old
grease has been pushed out. Use only
lithium base grease (such as Shin-
daiwa Gear Case Lubricant).
12-6 50 Hour Maintenance
Use a hooked wire to extract the
fuel filter from inside the fuel tank.
Remove and replace the filter ele-
ment. Before reinstalling the filter,
inspect the condition of the fuel
line. If damage or deterioration are
noted, the unit should be removed
from service until you can con-
sult with an authorized servicing
dealer.
Hooked
Wire
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.
Muffler Maintenance
Fuel Filter Maintenance
Hard starting or a gradual loss
of performance can be caused
by carbon deposits lodged in the
muffler’s spark arrester screen.
In such cases, performance can
usually be restored by removing
the spark arrester screen and giv-
ing it a thorough cleaning with a
stiff bristle brush.
If carbon deposits are severe or
if no performance improvement is
noted, your unit should be re-
turned to your Shindaiwa dealer
for inspection.
WARNING!
Never operate this unit with
a damaged or missing muffler or spark
arrester! Operating with missing or
damaged exhaust components is a
fire hazard and may also damage your
hearing.
