CHECK AND ADJUST THE CABLES

The cables are adjusted at the factory and no adjustment should be necessary. If the cables have become stretched or are sagging adjustment will be necessary.

Whenever belts are adjusted or replaced, the cables will need to be ad- justed.

Auger Drive Cable

WARNING: Do not over-tighten, as this may lift the lever and cause the auger drive to be engaged without depressing the auger drive control.

1.With the auger drive control lever released, the hook (A, Figure 29) should barely touch the lever (B) without raising it. There can be a maximum of 1/32" (0.8 mm) clearance.

2.To adjust, loosen the nut (C) by holding the adjusting flats (D) and turning the nut. Then, turn the adjusting flats and hold the adjust- ment screw (E). The adjustment screw is a phillips screw and the head can be held or turned by inserting a screwdriver through the spring (F).

3.Hold the adjusting flats and tighten the nut.

4.Start the engine and check the auger. The auger must not be engaged unless the auger drive control lever is depressed.

5.With the engine running, fully depress the auger drive control lever. The auger should engage and run normally.

6.Release the auger drive control lever. The auger must stop within five

(5) seconds.
