Section 4 - REPAIR & ADJUSTMENTS
WARNING
DO NOT attempt any maintenance, adjustments or
service with engine and blade running. STOP
engine and blade. Disconnect spark plug wire and
secure away from spark plug. Engine and
components are HOT. Avoid serious burns, allow
sufficient time for all components to cool. Wear
heavy leather gloves when handling or working
around cutting blades. Blades are extremely sharp
and can cause severe injury.
NOTE: The following sections 4.2 through
4.4 are for self-propelled models only.
4.2 WHEEL DRIVE CONTROL ADJUSTMENT
1. The wheel drive control is properly adjusted
when there is 1/16” to 1/8” clearance between the
inside of the spring hook and the inside of the
clutch cable eye with the wheel drive control
released. See Figure 4.4.

2. To adjust, unhook upper spring from cable eye
and rotate spring in direction required to extend or
shorten spring length.
3. Rehook upper spring to cable eye and check
clearance. Repeat procedure if required.
NOTE: The vinyl spring cover 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” position when released, check for
binding at the cable clips located on the side of the
right handle. The upper clip should be located 2”
below the upper bolt; the lower clip should be 4”
above the lower bolt. The cable should slide freely
with the clips installed at these locations.
