AUGER CONTROL

CABLE ADJUSTMENT

The length of the auger control cable is adjustable. However, it will seldom be necessary to change the cable length since the operating tension on the drive belt is maintained by the spring on the end of the cable.

If the auger turns too slowly under heavy load or momentary squealing of drive belt is heard when enter- ing heavy snow, pressure applied to drive belt by idler pulley must be increased by reducing the slack in the cable.

If the auger continues to turn when the auger control is released, the cable is too tight. The pressure applied to the drive belt must be eliminated by increasing the amount of slack to the cable adjustment.

WARNING

Make certain the cable is not placing and tension on the spring. If the cable places tension on the spring, the auger may turn when the control has not been engaged.

Checking the Adjustment.

1.Remove the cover. (See page 14.)

2.Measure the spring while the auger control on the handle is disengaged. Record this measurement.

3.Pull the auger control against the handle and again measure the spring. Record this measurement.

4.Compare the two measurements. The measurement obtained with the spring extended should be 7/16 inch (11 mm) greater than with the spring at rest.

Adjusting the Cable

1.Remove the engine cover.

2.Locate and loosen the lower locknut securing the auger control cable (shown in Figure 14).

3.To change the slack in the cable, turn the upper lock- nut slightly just until the slack between the spring and the exposed cable has been eliminated.

4.Tighten the lower locknut.

5.Test the units to make certain that the cable has been adjusted properly.

WARNING

Use extreme care when making adjustments that require engine to be running. Keep hands, feet, hair and loose fitting clothing away from moving parts.

Testing the Auger Control Cable

Start the snowthrower engine and pull back on auger control to operate auger. Release auger control and check to be sure auger stops turning.

If auger continues to turn after auger control is released, cable is too tight and will have to be adjust- ed to make it longer. Cable must be slightly slack when auger control is released (away from handle).

CARBURETOR ADJUSTMENT

The carburetor is properly calibrated and preset at the factory for efficient cold weather operation. There are no adjustments.
