To decrease the gap, loosen the upper cable nut. Then tighten the lower cable nut against the bracket. SPEED CONTROL BELL CRANK (Self-Propelled Models) The speed control bell crank holds the speed control rod in position after a speed has been set. The spring washers may become loose with normal wear. If the speed control rod does not stay firmly in position, adjust the speed control bell crank. See Figure 19. To adjust: 1. Remove cover, fully compress the helical spring lock washers with lock nut and then back lock nut off, one quarter turn. 2. If the speed control rod is still too loose, tighten lock nut by small increments until it holds its position. Tightening the lock nut too much will not allow the speed control rod to move at all. 3. Align notch in left hand side of cover with bolt and secure with knob. 1 6 2 4 5 Figure 18 2. Check the adjustment and readjust as needed. NOTE: If the gap between the friction disc and aluminum drive plate cannot be adjusted to this tolerance, take the unit to an authorized service dealer for repairs. 3 1. Lock Nut 2.
