52Maintenance Instructions REPLACING/REPAIRINGFuel FilterModel MBSSD is equipped with in-line fuel filters.Visually inspect the filter periodically, and replace thefilter yearly.Fuel Filter LocationIMPORTANT: Replace the fuel filter only in a cleanarea where the fuel line and connections will not becontaminated by any dust and dirt.1. Expand and slide clamps on either side of thefilter away from filter and pull fuel lines off filter.2. Replace filter.Mower BladesMower 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 ofsharpening and inspecting mower blades, if there areany 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 theblade has been ground away (removed) when theblade is sharpened. Replace the blade when lessthan a 3/4 in. (19 mm) flat section remains at theblade tip.• Examine ends of the blade carefully, especially theintersection where the flat section of the blade turnsup to form the “wing tip” (refer to Mower Blade Pro-file For Sharpening illustration in Sharpen MowerBlades instructions). Since sand and abrasive ma-terial can wear metal away in this area, the bladeshould be replaced when metal thickness hasworn to 1/16 in. (1.6 mm) or less.• Check the blades for straightness by markingblade 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 tiptrack is more than 1/8 in. (3 mm), the blade is bentand should be replaced.• Inspect the blade surface, especially in formedareas, for cracks. Replace the blade if any cracksare found.DANGERGasoline is extremely flammable and canbe highly explosive. To minimize danger:• Use only an approved fuel container forgasoline.• DO NOT allow open flames or sparksnear the machine while performing main-tenance or refueling; DO NOT smokewhile working with fuel.• Wipe up spilled gasoline immediatelyand completely.In-LineFuel FilterDANGERWhen 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 breakoff creating a serious potential for injury ordamage.WARNINGDO NOT try to straighten a blade that isbent. NEVER weld a broken or crackedblade. ALWAYS replace with a new bladeto assure safety.
