altitude and load.
Refer to the separate engine manual packed with
your unit for carburetor adjustment information.
DRIVE WHEELS (Model 800)
The wheels on the model 800 snow thrower may
be adjusted for three different methods of opera¬
tion. The adjustment is made by placing the klick
pins in one of two different holes on each side of
the unit. See figure 25.
1. Free Wheeling Operation—Place both klick
pins in the outside hole in the axle. This posi¬
tion allows easier movement when the engine
is not running.
2. Both Wheels Driving—Place both klick pins in
the hole in the hub next to the rim. This posi¬
tion is good for heavy snow as there is power
drive in both wheels.
3. O n e Wheel Driving — Place klick pin in the out¬
side axle hole on one side and in the hole in
the hub next to the rim on-the other. This posi¬
tion gives power drive to one wheel only, mak¬
ing the unit easier to maneuver.
FIGURE 25.

DRIVE WHEELS (Models 860 and 960)
Snow throwers model 860 and 960 are equipped
with a differential which makes the unit easy to
maneuver. It may be adjusted for two different
methods of operation. The adjustment is made by
placing the klick pins in one of two different holes
on each side of the unit. See figure 25.
1. Differential Action —Place klick pin in the out¬
side hole in the axle. This position allows easy
maneuvering when blowing light to medium
snow.
2. Straight Axle Action—Place klick pin in the
hole in the hub next to the rim on the right
wheel. This position should be used when
blowing heavy snow or when greater traction
is needed (icy surfaces, etc.). The unit will be
more difficult to maneuver.
DRIVE AND AUGER CLUTCH ADJUSTMENTS
To adjust the drive or auger clutch, unhook the
spring from the drive or auger bracket. Refer to
steps 21 and 22 under Assembly Instructions for
proper adjustment.

bolts have sheared. Two replacement hex bolts
and hex lock nuts have been provided with the
snow thrower. For future use, order part number
710-0891 (hex bolt 5/16-18 x 1.75" long) and
712-0429 (hex insert lock nut 5/16-18 thread).
SHAVE PLATE AND SKID SHOES
The shave plate and skid shoes on the bottom of
the snow thrower are subject to wear. They should
be checked periodically and replaced when
necessary. Skid shoes and shave plate are revers¬
ible for longer life. The skid shoes may also be in¬
verted to extend their life even further.
To remove shave plate, remove the carriage bolts,
lock washers and hex nuts which attach it to the
snow thrower housing. Reassemble new shave
plate, making sure heads of the carriage bolts are
to the inside of the housing. Tighten securely.
