with engine and blade running.
• STOP engine and blade.
• Disconnect spark plug wire and secure away from spark
plug.
Burn Hazard
• Engine and components are HOT.

1. The wheel drive control is properly adjusted when there is
1/16” to 1/8” (1.6 - 3.2 mm) clearance (G, Figure 27)
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
position when released, check for binding at the cable
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.
