HOW TO REPLACE
THE AUGER SHEAR BOLT
The augers are secured to the auger shaft
with special shear bolts. These shear bolts
are designed to break and protect the ma-
chine if an object becomes lodged in the au-
ger housing. Do not use a harder bolt as the
protection provided by the shear bolt will be
Iost.
_lb ARNING: For safety and to
protect the machine, use only
original equipment shear bolts.
To replace a broken shear bolt, proceed
as follows. Extra shear bolts were pro-
vided in the assembly parts bag.
1. Move the throttle control to the stop
position. Disengage all controls.
2. Disconnect the spark plug wire.
Make sure all moving parts have
stopped.
3. Align the hole in the auger with the
hole in the auger shaft. Install the
new shear pin and spacer. See
Figure 38.
4. Connect the spark plug wire.

TO ADJUST
THE CARBURETOR
If you think your carburetor needs ad-
justing, see your nearest Craftsman
Store. Engine performance should not
be affected at altitudes up to 7,000 feet.
For operation at higher elevations, con-
tact your nearest Sears Store.
IMPORTANT: Never tamper with the
engine governor, which is factory set for
proper engine speed. Over-speeding
F-011050L
the engine above the factory high
speed setting can be dangerous. If you
think the engine-governed high speed
needs adjusting, contact your nearest
Sears Store, which has the proper
equipment and experience to make any
necessary adjustments.
TO ADJUST OR REPLACE
THE SPARK PLUG
If you have difficulty starting the snow
thrower, adjust or replace the spark
plug. Replace the spark plug is the
electrodes are pitted or burned or if the
porcelain is cracked. Follow the instruc-
tions below.
To adjust:
1. Clean spark plug by carefully
scraping the electrodes (Do not
sand blast or use a wire brush).
2. Be sure spark plug is clean and
free of foreign material. Check elec-
trodes gap with a wire feeler gauge
and reset gap to 0.030" if neces-
sary. See Figure 39.
To Replace:
1. If you need a new spark plug, use
only the proper replacement spark
plug.
2. Set the gap to 0.030 inches.
3. Before installing the spark plug,
lightly coat the spark plug threads
with oil or grease to insure easy re-
moval.
4. Firmly tighten the spark plug in the
engine.
5. If a torque wrench is available,
torque the plug to 18 to 23 foot
pounds.
