Traction Drive Clutch
Adjust traction clutch to compensate for wear of friction
wheel when slippage occurs.
To adjust traction clutch:
1. Place speed selector in First (1) forward and tip
unit forward onto housing.
2. With one hand, pull the wheel drive clutch arm
upward until a positive stop is obtained (Figure 12).
With the other hand move the traction drive clutch
lever toward the handle grip until all cable slack is
removed, and hold it there.
3. Measure the distance between the lever and
handle grip. Proper measurement is 3-1/4 to 3-3/4"
(8.25 - 9.52 cm) (Figure 11). Shortening the cable
by 1/16" (1.6 mm) with the adjusting sleeve will
increase lever-to-handle grip measurement by
1/4" (6.35 mm).
4. Lock adjusting sleeve with jam nut when
adjustment is complete. Restrain adjusting sleeve
with wrench when applying torque to jam nut.
Speed Selector
To adjust:
1. Loosen the bottom nut on the threaded end of the
speed selector rod (Figure 12).
2. Position speed selector in (6) "Fast" speed notch.
3. Position speed selector arm in its maximum down
position and tighten both nuts against swivel.
