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
lost.
A
WARNING: 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 33.
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 Craftsman Store.
IMPORTANT: Never tamper with the
engine governor, which is factory set for
proper engine speed. Over-speeding
the engine above the factory high
speed setting can be dangerous, if you
think the engine-governed high speed
needs adjusting, contact your nearest
Craftsman Store, which has the proper
equipment and experience to make any
necessary adjustments.
TO ADJUST OR REPLACE THE
SPARK PLUG
NOTE: This spark ignition system
meets all requirements of the Canadian
Interference-Causing Equipment Regu­
lations.

current Australian and New Zealand
limitations regarding electromagnetic
interference.
If you have difficulty starting the snow
thrower, adjust or replace the spark
plug. Replace the spark plug is the

tions below.
To adjust:
1. Clean spark plug by carefully
scraping the electrodes (Do not
sand blast or use a wire brush).
