REPLACING/REPAIRING
Fuel Filter
Model MBSSD is equipped with in-line fuel filters.
Visually inspect the filter periodically, and replace the
filter
yearly.
Fuel Filter Location
IMPORTANT:
Replace the fuel filter only in a clean
area where the fuel line and connections will not be
contaminated by any dust and dirt.
1.
Expand and slide clamps on either side of the
filter away from filter and pull fuel lines off filter.
2.
Replace filter.
Mower Blades
Mower blades are removed and remounted as de-
scribed in the
Sharpen Mower Blades
instructions
(refer to
CHECKING/SERVICING
to
Sharpen Mow-
er Blades
in this section). During the course of
sharpening and inspecting mower blades, if there are
any of the following conditions of wear
or dam-
age,
blades should be replaced
for reasons of safe-
ty and performance of the machine:
•
An excessive amount of the
flat section
of the
blade has been
ground away
(removed) when the
blade is sharpened. Replace the blade
when less
than a 3/4 in. (19 mm) flat section remains
at the
blade tip.
•
Examine ends of the blade carefully, especially the
intersection where the flat section of the blade turns
up to form the “wing tip” (refer to
Mower Blade Pro-
file For Sharpening
illustration in
Sharpen Mower
Blades
instructions). Since sand and abrasive ma-
terial can wear metal away in this area, the blade
should be
replaced when metal thickness has
worn to 1/16 in. (1.6 mm) or less.
•
Check the blades for
straightness
by marking
blade tip position inside the deck housing and then ro-
tating the opposite end of the blade to the same po-
sition and comparing. If the difference in blade tip
track is
more than 1/8 in. (3 mm),
the blade is bent
and
should be replaced.
•
Inspect the blade surface, especially in formed
areas, for
cracks.
Replace the blade if any cracks
are found.
DANGER
Gasoline is extremely flammable and can
be highly explosive. To minimize danger:
•
Use only an approved fuel container for
gasoline.
•
DO NOT allow open flames or sparks
near the machine while performing main-
tenance or refueling; DO NOT smoke
while working with fuel.
•
Wipe up spilled gasoline immediately
and completely.

DANGER
When blades are operated over sandy soil,
and if blades are allowed to wear, a “slot”
may be worn into the wing tip of blade.
Eventually a piece of the blade may break
off creating a serious potential for injury or
damage.
WARNING
DO NOT try to straighten a blade that is
bent. NEVER weld a broken or cracked
blade. ALWAYS replace with a new blade
to assure safety.
