IMPORTANT: Replace the fuel lter only in a clean
area where the fuel line and connections will not be
contaminated by any dust and dirt.
DANGER
Gasoline is extremely ammable and can
be highly explosive. To minimize danger:
• Use only an approved fuel container for
gasoline.
• DO NOT allow open ames 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
lter away from lter and pull fuel lines off lter.
2. Replace lter.
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 at 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) at section remains at the
blade tip.
• Examine ends of the blade carefully, especially the
intersection where the at section of the blade turns
up to form the “wing tip” (refer to Mower Blade Pro-
le 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.
