REPLACING/REPAIRING
Fuel Filter - Model MBS26
WARNING
The MBS26 fuel system operates under
high pressure. This system should be ser-
viced by a Walker dealer or authorized
Kohler service dealer.
Model MBS26 is equipped with a high-volume, high-
pressure, 10-15 micron, in-line fuel filter. Replace-
ment of this filter is recommended
every 1500 hours
of operation or more frequently under extremely dusty
or dirty conditions. Because the MBS26 has a pres-
surized fuel system, fuel filter replacement should be
done by a Walker dealer or authorized Kohler service
dealer.

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.
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.
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 sharp-
ening 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.
