Adjusting the Traction Drive
Cable
Check the traction drive cable for proper adjustment
initially, after the first operating hour, and then annually
thereafter.
Checking the Traction Drive Cable
1. Stop the engine and wait for all moving parts to stop.
2. Squeeze the control bar toward the handle.
3. Hold the control bar against the right side of the handle
as shown in Figure 11.

4. Ensure that the distance between the pivot plate and the
wheel frame is 0 to 1/8 in. (0 to 3 mm) as shown in
Figure 12.

Important
If the pivot plate touches the wheel frame
before the control bar touches the handle, the cable is too
tight. Adjust the cable to increase the gap between the pivot
plate and the wheel frame, but ensure that the gap is not
more than 1/8 in. (3 mm). Adjusting the cable correctly
minimizes the effort needed to operate the control bar.
Adjusting the Traction Drive Cable
Unhook the Z-fitting from the pivot cable adjuster
(Fig. 12), and position the Z-fitting in a different hole on
the pivot cable adjuster to obtain the proper gap between
the pivot plate and the wheel frame.
Note: Moving the Z-fitting to a hole closer to the ground
decreases the gap between the pivot plate and the wheel
frame; moving it to a hole farther from the ground increases
the gap.
Note: The traction is most aggressive (the traction speed is
fastest) when the rotor blades are new. If you want to
reduce the aggressiveness of the traction, move the
Z-fitting one hole farther from the ground. The gap
between the pivot plate and the wheel frame will be about
1/4 in. (6 mm).
After the rotor blades have worn slightly, the traction won’t
feel as aggressive. To increase the traction, adjust the
traction drive cable to attain the original gap between the
pivot plate and the wheel frame of 0 to 1/8 in. (0 to 3 mm).
Replacing the Rotor Blades
Before each season, inspect the rotor blades for wear. When
a rotor blade edge has worn down to the wear indicator
hole (Fig. 13), replace all three rotor blades to ensure
proper performance and to prevent damage to the underside
of the snowthrower.

Important
Replace the scraper whenever you replace
the rotor blades. This ensures proper snowthrower
operation and performance.
Note: The running time and the roughness of the driveway
or the sidewalk determines the wear rate of the rotor blades.
