Final Adjustments
Auger Drive Clutch
To check the adjustment of the auger drive clutch,
push forward on the left hand clutch grip (depress
the rubber bumper). There should be slack in the
cable. See Figure 6.
Release the clutch grip. The cable should be
straight. Make certain you can depress the auger
drive clutch grip against the left handle completely.
If necessary, loosen the hex lock nut and thread the
cable in (for less slack) or out (for more slack) as
necessary. Recheck the adjustment. Tighten the
lock nut against the cable when correct adjustment
is reached.
Figure 6
Traction Drive Clutch and Shift Lever
Tip the snow thrower forward so that it rests on the
auger housing.
Move the shift lever all the way forward to sixth (6)
position.
With the traction drive lever released, spin the snow
thrower wheels by hand. The wheels should turn;
however, you may feel some resistance.
Engage the traction drive clutch grip. The wheels
should no longer turn.
Now release the traction drive clutch grip, and spin
the wheels 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 turn.
If you face resistance when moving the shift lever
or the snow thrower wheels stop when they should
not, loosen the lock nut on the traction drive cable
and unthread the cable one turn.
If the wheels can still be turned when you engage
the traction drive clutch grip, loosen the same lock
nut again and thread the cable in one turn.
Recheck the adjustment and repeat adjustment as
necessary. Tighten the lock nut to secure the cable
when correct adjustment is reached.
NOTE: If you are not sure that you have reached
correct adjustment, refer to the Making Adjustments
section of this manual on page 11.
Slide Shoe
The space between the shave plate and the ground can
be adjusted. For close snow removal, place slide shoes
in the low position. Use middle or high position when
area to be cleared is uneven. See Figure 7.
Adjust slide shoes by loosening the two hex nuts
and carriage bolts on each side and moving slide
shoes to desired position. See Figure 7.
Make certain the entire bottom surface of slide
shoe is against the ground to avoid uneven wear on
the slide shoes.
Tighten nuts and bolts securely.
Figure 7
NOTE: It is not recommended that you operate this
snow thrower on gravel as loose gravel can be easily
picked up and thrown by the auger causing an injury or
damage to the snow thrower.
If for some reason, you have to operate the snow
thrower on gravel, keep the slide shoe in the
highest position for maximum clearance between
the ground and the shave plate.
NOTE:
Tire Pressure (Pneumatic Tires)
The tires are over-inflated for shipping purposes.
Check tire pressure and reduce to 15 to 20 psi.
NOTE: If the tire pressure is not equal in both tires, the
unit may pull to one side or the other.
