REPLACING/REPAIRING

Fuel Filter

Model MBSSD is equipped with in-line fuel filters. Visually inspect the filter periodically, and replace the filter yearly.

In-Line

Fuel Filter

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.

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 described in the Sharpen Mower Blades instructions (refer to CHECKING/SERVICING to Sharpen Mower 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 safety 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.

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.

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.

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.
