LAMP WIRING (If Equipped)
Figure 18
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:
