71Maintenance Instructions CHECKING/SERVICINGFuel Lines and ClampsEvery year, inspect the fuel supply line from thetank to engine for deterioration or damage. Also,inspect the fuel line clamps for tightness. Goodpreventive maintenance calls for complete replace-ment of fuel lines and clamps every two (2) years.Engine StarterYearly or every 500 hours disassemble and cleanthe solenoid shift starter. Refer to the Kohler ServiceManual for this procedure or contact an authorizedKohler engine dealer to perform this service.Transmission Control SettingOn a yearly interval or when an out-of-adjustmentcondition is observed, check the transmission con-trol for proper function as follows:Neutral-ParkWith the mower parked on level ground, start andrun the engine, first at idle and then normal operat-ing speeds. With the FSC in the NEUTRAL-PARKposition, there should be no movement of eitherdrive tire. If the tire(s) are “creeping” forward or re-verse, refer to ADJUSTMENTS for the NeutralFunction Adjustment - Step 3 in this section.Straight Ground TrackingCheck for straight ground track by driving on asmooth, level surface with hands off the steering le-vers. Set the FSC at different speeds and observeif the mower moves in a straight line (use a cementjoint or other line on the ground for reference). If themachine is drifting to the right or left, refer toADJUSTMENTS for Straight Ground Travel Adjust-ment - Step 4 in this section.Blade Brake ActionWARNINGIt is important to check and maintain bladebrake action for safe operation of the ma-chine.Check the function of the cutter blade brake (andblower brake on GHS models) by engaging the bladeclutch (PTO), operating the engine at full throttle,then disengaging the clutch and measuring howquickly the blades stop. Watch the rotation of theblade drive shaft and blower pulley as a visual indica-tion that movement has stopped. If the brake isworking properly, all rotation will stop five (5)seconds after disengagement of the clutch. If thebrake system malfunctions - blades do not stop infive (5) seconds - adjust or repair the brake beforeoperating the mower. Contact your Walker dealer forthis service or refer to ADJUSTMENTS for ClutchDisengagement/Brake Action, Step 3 - Blade BrakeBand Adjustment on page 87PTO U-JointsThe PTO U-joints should be inspected yearly forlooseness and wear.
