Follow the steps below to accomplish this.WARNING!Disconnect the machine’s battery pack connector (13) before servicing.• Note: See Figures 6.6 & 6.8. Before making any adjustments, inspect the Torsion Spring (AL) for defects and the correct positions of both spring ends (repairor replace).To Adjust Pedal Spring1 Loosen the Screw (AM) & Nut (AN), the screw with bushing is positioned between both Fwd & Rev torsion spring ends. Its placement controls the neededpre-load pressure to eliminate excessive pedal free-play and a balanced spring rate to return the pedal to a centered (neutral) position.2 Push the screw back into the pedal frame slot to increase spring tension and eliminate pedal free play. Then tighten the screw & nut being careful not to pullon the linkage connection to the pot shaft and disturb (move) its neutral setting.To Replace Pedal or Spring3 Position the torsion spring ends (A & B) as shown. This is with the Bushing (AO) and Screw (AM) not installed.4 Place the bushing inside the pedal channel pilot it into position using a scratch awl or a pin punch.5 Then pivot (press) the pedal and insert the screw from the opposite side pushing the guide tool out.6 Use a screwdriver to tap and pry the bushing back in the pedal slot to increase spring tension7 Work the bushing back & forth on both sides of the pedal to obtain equal spacing. Then tighten the screw and nut.8 A correctly adjusted drive pedal will have minimal amount of free-play when selecting a drive direction.9 Reconnect the batteries and test the machine to make sure it does not “creep” forward or reverse when the pedal returns to neutral.10 Service Tip: Also confirm the Hourmeter/Status Display (K) is free of the error code 03 (drive system fault). If error 03 is shown the throttle is not set properlyfor the potentiometer and or drive pedal neutral position. Check both again and readjust.
