IMPELLER SHEAR BOLTS
The impeller is secured to the impeller shaft with two (2) 
capscrew/shear bolts and hex nuts. Should a foreign object 
or ice become lodged in the impeller, the capscrews are 
de signed to break, preventing damage to any other com-
 po nents. If impeller does not turn when auger control lever 
is engaged, check to see if the capscrews have sheared. 
To replace the capscrew/shear bolts:
1.   Disengage all controls and move throttle control to 
STOP position. Wait for all moving parts to stop.
2.    Disconnect spark plug wire from spark plug and place 
wire where it cannot come in contact with plug.
3.    Align holes in impeller hub with holes in impeller shaft 
and install two (2) new 1/4-20 x 1-5/8" capscrew/shear 
bolts. Install 1/4-20 locknuts and tighten securely.
CAUTION: Do not substitute. Use only original 
equip ment capscrew/shear bolts as sup plied 
with your snow thrower.
4.    Connect spark plug wire to spark plug.
WARNING: To avoid serious injury, before performing any service or ad just ments:
1.  Be sure throttle is in STOP position.
2.  Remove safety ignition key.
3.  Make sure the augers and all mov ing parts have completely stopped.
4.  Disconnect spark plug wire from spark plug and place wire where it can not contact plug.
MAINTENANCE
MUFFLER
Inspect and replace corroded muffl er as it could cre ate a 
fi re haz ard and/or dam age.
SPARK PLUG
Replace spark plug at the beginning of each season or after 
every 100 hours of operation, whichever occurs fi rst.  Spark 
plug type and gap setting are shown in the “PROD UCT

CLEANING
IMPORTANT:  For best performance, keep snow thrower 
housing free of any dirt or trash. Clean the outside of your 
snow thrower after each use.
