Auger/Impeller Drive Control Linkage — All Other Models

There are two adjustment mechanisms used. One has a clevis with a jam nut. The other has a rod going through a loop with a flange nut on either side.

1.Thread a hex flange nut (flange side down) onto upper control rod located on right handle (Figure 53).

6.Remove the belt cover (refer to "REPLACING THE AUGER/IMPELLER DRIVE BELT", page 2 - 1, steps 1-2). Compress the auger/ impeller control lever and check that the slack is removed from the auger drive belt when the lever is 1-2 inches (2.5-5 cm) above the handgrip (Figure 54).

7.Adjust the clevis or two flange nuts to obtain this dimension, then tighten the two nuts or jam nut securely (Figure 55).

2.Install lower link through outer hole in lower control rod.

3.Insert upper control rod through loop in lower link control rod.

4.Thread a flange lock nut (flange side up) onto bottom of upper control rod below loop in lower link.

5.Check the distance between the top of the handgrip and the bottom of the auger/impeller control lever (Figure 54). This is a preliminary setting only.

8.The auger must stop when the handgrip is released. If it does not stop, adjust the clevis or flange units on the auger rod.
