Maintenance Instructions
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.
