1. The wheel drive control is properly adjusted when there

between the inside of the spring hook (E) and the inside
of the clutch cable eye (C) with the wheel drive control
released.
2. To adjust, unhook the upper spring (D) from the cable eye
and rotate the spring in the direction required to extend or
shorten the spring length.
3. Rehook the upper spring to the cable eye and check
clearance. Repeat the procedure if required.
Note: The vinyl spring cover (B) should be kept over the
spring at all times except for adjustments.
4. If the wheel drive control fails to return quickly to the OFF

holdings located on the side of the right handle. The
upper clip should be located 2" (5 cm) below the upper
knob; the lower clip should be 4" (10 cm) above the lower
knob. The cable should slide freely with the clips installed
at these locations.
