TO REPLACE AUGER SHEAR BOLT

The augers are secured to the auger shaft with special bolts (see figure below ) that are designed to break (to protect the ma- chine) if an object becomes lodged in the auger housing. Use of a harder bolt will de- stroy the protection provided by the shear bolt.

IMPORTANT: To ensure safety and perfor- mance levels, only odginalequipment shear bolts should be used. When replacingshear

pacers.

To replace a broken shear bolt, proceed as follows:

•Move the throttle to O (Stop) and tum oft all controls.

•Disconnect the spark plug wire. Be sure all moving parts have stopped.

•Remove the broken shear bolt.

•Align the hole in the auger with the hole in the auger shaft. Install the new shear pin and spacer found in toolbox located on top of belt cover.

•Reconnect the spark plug wire.

TO ADJUST CARBURETOR

If you think your carburetor needs adjusting, see your nearest Authorized Craftsman Ser-

vice Center. Engine performance should not be affected at altitudes up to 7,000 feet.

For operation at higher elevations, contact your Authorized Craftsman Service Center.

IMPORTANT: Never tamper with the en- gine governor, which is factory set for proper engine speed. Over speeding the engine above the factory high speed set- ting can be dangerous. If you think the en- gine-governed high speed needs adjusting, contact your nearest Craftsman Service Center, which has the proper equipment

and experience to make any necessary ad- justments.
