Engine  
Listed below are general recommendations about  
maintaining your snow thrower engine. For further details,  
refer to the accompanying engine manual.  
Servicing Augers  
The augers are secured to the spiral shaft with four  
shear pins and cotter pins. If you hit a foreign object or  
ice jam, the snow thrower is designed so that the pins  
may shear. Refer to Figure 9.  
1. Before operating snow thrower, check the oil level.  
NOTE:  
2. Change engine oil after first two hours of operation  
and every 25 hours thereafter.  
If auger continues to  
rotate with the control  
disengaged, shut off  
engine and re-adjust.  
If the augers do not turn, check if the pins have sheared.  
Replace, if needed, with proper shear pins. Refer to  
item 42 on page 17 for part number.  
3. Clean spark plug and reset the electrode gap to  
0.030” at least once a season or every 100 hours of  
operation; replace every 200 hours of operation.  
IMPORTANT: NEVER replace the auger shear pins with  
standard pins or fasteners. Any damage to the auger  
gearbox or other components, as a result of doing so,  
will NOT be covered by your snow thrower’s warranty.

MTD” warrants this product against defects in material and workmanship  
for a period of two (2) years commencing on the date of original purchase  
and will, at its option, repair or replace, free of charge, any part found to

apply if this product has been operated and maintained in accordance  
with the Operator’s Manual furnished with the product, and has not been  
subject to misuse, abuse, commercial use, neglect, accident, improper  
maintenance, alteration, vandalism, theft, fire, water, or damage because  
of other peril or natural disaster. Damage resulting from the installation or  
use of any part, accessory or attachment not approved by MTD for use  
with the product(s) covered by this manual will void your warranty as to  
any resulting damage.  
Normal wear parts are warranted to be free from defects in material and  
workmanship for a period of thirty (30) days from the date of purchase.

f. Replacement parts that are not genuine MTD parts.  
g. Transportation charges and service calls.  
No implied warranty, including any implied warranty of merchant-

period of express written warranty above as to the parts as identi-  
fied. No other express warranty, whether written or oral, except as  
mentioned above, given by any person or entity, including a dealer  
or retailer, with respect to any product, shall bind MTD. During the  
period of the warranty, the exclusive remedy is repair or replacement
