How To Adjust The Belt Guide
1.Disconnect spark plug wire.
2.(Figure 13) Remove screw (2). Remove the belt cover (1).
3.(Figure 2) Engage the auger drive lever (5).
4.(Figure 17) Measure the distance between the belt guide (2) and auger drive belt (3). The correct distance (4) is 1/8 inch (3.175 mm).
5.If an adjustment is necessary, loosen the mounting bolt for the belt guide (2). Move the belt guide (2) to the correct position
(4). Tighten the mounting bolt for the belt guide (2).
6.(Figure 13) Install the belt cover (1). Tighten screw (2).
7.Connect the spark plug wire.
How To Adjust Or Replace The Friction Wheel
How To Check The Friction Wheel
If the snow thrower will not move forward, check the traction drive belt, the traction drive cable or the friction wheel. If the friction wheel is worn or damaged, it must be replaced. See “How To Replace the Friction Wheel” in this section. If the friction wheel is not worn or damaged, check as follows.
1.(Figure 2) Remove the gas from the gas tank. Stand the snow thrower up on the front end of the auger housing (4).
WARNING: Drain the gasoline out- doors, away from fire or flame.
2.Disconnect the spark plug wire.
3.(Figure 16) Loosen the bolts (3) on each side of the bottom panel (2).
4.Remove the bottom panel (2).
5.(Figure 2) Position the shift speed lever (6) in the lowest forward speed.
6.(Figure 18) Note the position of the friction wheel (4). The correct distance “A” from the right side of the friction wheel (4) to the out-
side of the motorbox is as follows:
Tire Size | Distance “A” |
12 and 13 inch | |
16 inch |
If the friction wheel (4) is not in the correct position, adjust as follows.

How To Replace the Auger Shear Bolt
The augers are secured to the auger shaft with special shear bolts. These shear bolts are de- signed to break and protect the machine if an object becomes lodged in the auger housing. Do not use a harder bolt as the protection pro- vided by the shear bolt will be lost.
