2 - 12 Two Stage Snowthrower Drive Systems Manual
ADJUSTING THE SPEED SELECTOR
If the snowthrower is slow, the No.1 speed selection
has no speed, or the speed selector does not move
into the No. 3 speed selection, adjust the speed
selector linkage.
1. Disconnect the wire from the spark plug and make
sure that the wire does not contact the spark plug.
2. Tip the snowthrower forward and block it so that it
cannot fall.
3. Remove the four screws that secure the bottom
cover to the frame and remove the cover.
4. Loosen the flange nuts that secure the selector
plate to the control panel (Figure 65).

5. Shift the speed selector to third gear and push
down on the speed selector plate to move the
drive assembly to the right.
Note: The drive assembly should be 1/8 inch
(3mm) from the roll pin; if not, slide the selector
plate (Figure 65) until the gap is 1/8 inch (3mm)
(Figure 66).

6. With the drive assembly 1/8 inch (3mm) from the
roll pin, tighten the flange nuts that secure the
speed selector plate.
7. Shift the speed selector to the R (Reverse)
position and back to third gear to check the
adjustment.
8. If the space between the roll pin and the drive
assembly is more than 3/16 inch (5 mm), repeat
steps 4 through 7.
9. Install the bottom cover and return the
snowthrower to the upright position.
