Adjusting the Speed Selector
Adjust the speed selector linkage initially and when the
snowthrower is slow, first gear has no speed, or the speed
selector does not move into third gear.
1. Stop the engine and wait for all moving parts to stop.
2. Disconnect the wire from the spark plug and ensure that
the wire does not contact the spark plug (Fig. 16).
3. Tip the snowthrower forward and block it so that it
cannot fall.
4. Remove the four flange-head bolts that secure the
bottom cover to the frame and remove the cover
(Fig. 26).
5. Loosen the flange nuts that secure the selector plate to
the control panel (Fig. 22).

(3 millimeters); refer to Figure 23.

after every five operating hours thereafter, and when the
speed selector shifts properly but the snowthrower does not
drive in the forward or reverse speeds.
1. Stop the engine and wait for all moving parts to stop.
2. Disconnect the wire from the spark plug and ensure that
the wire does not contact the spark plug (Fig. 16).
3. Check and adjust the traction drive as described in steps

contact an Authorized Service Dealer.
