13.When the engine starts, release the starter button and  
slowly rotate the choke to OFF position. If the engine  
falters, rotate the choke to FULL and then gradually to  
OFF.  
Auger Control Test  
IMPORTANT: Perform the following test before operating  
the snow thrower for the first time and at the start of each  
winter season.  
NOTE: When engaging the electric starter, a slight hesita-  
tion of a few seconds may occur before the engine starts  
to turn. This is normal and is not harmful to the engine.  
Check the adjustment of the auger control as follows:  
1. When the auger control is released and in the  
disengaged “up” position, the cable should have very  
little slack, but should NOT be tight.  
10  
Download from Www.Somanuals.com. All Manuals Search And Download.  
WARNING: Do not over-tighten the  
cable. Over-tightening may prevent the  
auger from disengaging and compro-  
mise the safety of the snow thrower.  
Operating Tips  
For most efficient snow removal, remove snow  
immediately after it falls.  
5
Discharge snow downwind whenever possible. Slightly  
overlap each previous path.  
2. In a well-ventilated area, start the snow thrower  
engine as instructed earlier in this section under the  
heading Starting Engine. Make sure the throttle is set  
in the FAST position.  
Set the skid shoes 1/4-inch below the shave plate  
for normal usage. The skid shoes may be adjusted  
upward for hard-packed snow.  
Operation  
3. While standing in the operator’s position (behind the  
snow thrower) engage the auger.  
NOTE: It is not recommended that you operate this snow  
thrower on gravel as loose gravel can be easily picked up  
and thrown by the auger causing personal injury and/or  
damage to the snow thrower.  
4. Allow the auger to remain engaged for approximately  
10 seconds before releasing the auger control. Repeat  
this several times.  
If for some reason, you have to operate the snow  
thrower on gravel, keep the skid shoe in the highest  
position for maximum clearance between the ground  
and the shave plate.  
5. With the engine running in the FAST position and the  
auger control in the disengaged “up” position, walk to  
the front of the machine.  
WARNING  
Do not over-tighten the  
cable. This may prevent the  
auger from disengaging  
and compromise  
the safety of the snow  
thrower.  
6. Confirm that the auger has completely stopped  
rotating and shows NO signs of motion.  
Clean the snow thrower thoroughly after each use.  
IMPORTANT: If the auger shows ANY signs of rotating,  
immediately return to the operator’s position and shut  
off the engine. Wait for all moving parts to stop before  
readjusting the auger control cable as shown in the  
“Setup and Adjustment” section.  
Cleaning The Chute Assembly  
The clean-out tool is conveniently fastened to the rear of  
the auger housing with a mounting clip. When snow and  
ice collect in the chute assembly during operation, use  
this tool to safely clean the chute and chute opening.  
Stop engine by moving  
throttle lever to stop posi-  
tion and wait for all moving  
parts to stop before using  
the clean-out tool.

WARNING: Never use your hands to  
clean snow and ice from the chute  
assembly or auger housing.  
5. While the auger control is engaged, squeeze the drive  
control completely against the upper handle to engage  
the wheels. Do not “feather” the drive control.  
6. As the snow thrower begins to move, maintain a firm  
hold on the handle, and guide the snow thrower along  
the path to be cleared.  
5. Refasten the clean-out tool to the mounting clip on the  
rear of the auger housing.  
7. Release the auger and drive controls to stop the snow  
throwing action and forward motion.  
NOTE: Your unit is equipped with a clutch in the transmis-  
sion. If the wheels stop turning while trying to discharge  
large volumes of snow, immediately disengage the drive  
control and allow the rotating augers to discharge snow  
from the housing. Reduce the clearing width and continue  
operation.  
8. On each succeeding pass, readjust the chute  
assembly to the desired position and slightly overlap  
the previously cleared path.

MANUFACTURER’S LIMITED WARRANTY FOR  
The limited warranty set forth below is given by MTD LLC with respect  
to new merchandise purchased and used in the United States, its  
possessions and territories.  
e. MTD does not extend any warranty for products sold or exported  
outside of the United States, its possessions and territories, except  
those sold through MTD’s authorized channels of export distribution.  
“MTD” warrants this product against defects in material and workman-  
ship 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 be defective in materials or workmanship. This limited war-  
ranty shall only 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.  
Normal wear parts include, but are not limited to items such as: batter-  
ies, belts, blades, blade adapters, grass bags, rider deck wheels, seats,  
snow thrower skid shoes, shave plates, auger spiral rubber and tires.  
HOW TO OBTAIN SERVICE: Warranty service is available, WITH  
PROOF OF PURCHASE, through your local authorized service  
dealer. To locate the dealer in your area, check your Yellow Pages,  
or contact MTD LLC at P.O. Box 361131, Cleveland, Ohio 44136-  
0019, or call 1-800-800-7310 or 1-330-220-4683 or log on to our  
f. Replacement parts that are not genuine MTD parts.  
g. Transportation charges and service calls.  
No implied warranty, including any implied warranty of mer-  
chantability of fitness for a particular purpose, applies after the  
applicable period of express written warranty above as to the  
parts as identified. 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 of the product as set forth above.  
The provisions as set forth in this warranty provide the sole and  
exclusive remedy arising from the sale. MTD shall not be liable  
for incidental or consequential loss or damage including, without  
limitation, expenses incurred for substitute or replacement lawn  
care services or for rental expenses to temporarily replace a  
warranted product.  
Some states do not allow the exclusion or limitation of incidental or  
consequential damages, or limitations on how long an implied warranty  
lasts, so the above exclusions or limitations may not apply to you.  
In no event shall recovery of any kind be greater than the amount of the  
purchase price of the product sold. Alteration of safety features of  
the product shall void this warranty. You assume the risk and liability  
for loss, damage, or injury to you and your property and/or to others and  
their property arising out of the misuse or inability to use the product.  
This limited warranty shall not extend to anyone other than the original  
purchaser or to the person for whom it was purchased as a gift.  
HOW STATE LAW RELATES TO THIS WARRANTY: This limited  
warranty gives you specific legal rights, and you may also have other  
rights which vary from state to state.  
This limited warranty does not provide coverage in the following cases:  
a. The engine or component parts thereof. These items may carry a  
separate manufacturer’s warranty. Refer to applicable manufacturer’s  
warranty for terms and conditions.  
b. Log splitter pumps, valves, and cylinders have a separate one year  
warranty.  
c. Routine maintenance items such as lubricants, filters, blade  
sharpening, tune-ups, brake adjustments, clutch adjustments, deck  
adjustments, and normal deterioration of the exterior finish due to  
use or exposure.  
IMPORTANT: Owner must present Original Proof of Purchase to obtain  
warranty coverage.  
d. Service completed by someone other than an authorized service  
dealer.
