1.Wrap the wire from the lamp down the right handle until the wire can be plugged into the alternator lead wire under the fuel tank. See Figure 18. Be sure lamp wire does not interfere with the movement of any controls or cables.

IMPORTANT: After attaching the shift rod and clutch cables, check the adjustments as instructed, and make any final adjustments necessary before operating your snow thrower. Failure to follow the instructions may cause damage to the snow thrower.

FINAL ADJUSTMENTS

Auger Drive Clutch

1.To check the adjustment of the auger drive clutch, push forward on the left hand clutch grip depressing the rubber bumper under the clutch grip. There should be slack in the cable.

2.Release the clutch grip. The cable should be straight. Make certain you can depress the auger drive clutch grip against the left handle completely.

3.If necessary, loosen the hex jam nut and thread the cable in (for less slack) or out (for more slack) as necessary. Refer to Figure 13. Recheck the adjustment. Tighten the jam nut against the cable when correct adjustment is reached.

Traction Drive Clutch and Shift Lever Adjustment

To check the adjustment of the traction drive clutch and shift lever:

1.Move the shift lever all the way to the highest speed. With the traction drive lever released, push the snow thrower forward. The unit should roll forward.

2.Then engage the traction drive clutch grip. The wheels should stop turning.

3.Now release the traction drive clutch grip, and push the unit again. Move the shift lever back to the fast reverse position, then all the way forward again. There should be no resistance in the shift lever, and the wheels should keep turning.

4.If you have resistance when moving the shift lever or the wheels stop when they should not, loosen the jam nut on the traction drive cable and unthread the cable one turn. If the wheels do not stop when you engage the traction drive clutch grip, loosen the jam nut on the traction drive cable and thread the cable in one turn. Recheck the adjustment and repeat as necessary.

5.Tighten the jam nut to secure the cable when correct adjustment is reached.

NOTE: If you are uncertain that you have reached the correct adjustment, refer to SECTION 8: ADJUSTMENTS.
