2. Squeeze the auger control against the handle and the
augers will turn. Release it and the augers will stop.
3. Squeeze the drive control against the handle the
snow thrower will move. Release it and drive motion
will stop.
To Engage Augers
1. To engage the augers and start throwing snow,
squeeze the auger control against the left handle.
Release to stop the augers.
Auger Control Test
Perform the following test before operating your snow
thrower for the first time and at the start of each winter.
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. It should NOT be tight.
2. In a well-ventilated area, start the snow thrower
engine as instructed on the previous page. Make sure
the throttle is set in the FAST position.
3. While standing in the operator’s position (behind the
snow thrower), engage the auger.
4. Allow the auger to remain engaged for approximately
ten (10) seconds before releasing the auger control.
Repeat this several times.
5. With the throttle control in the FAST (rabbit) position
and the auger control in the disengaged “up” position,
walk to the front of the machine.
6. Confirm that the auger has completely stopped
rotating and shows NO signs of motion. 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 re-adjusting the
auger control.
7. To readjust the control cable, loosen the upper hex
nut on the auger cable bracket.
8. Position the bracket upward to provide more slack (or
downward to increase cable tension). See Figure 2.
9. Retighten the upper hex nut.
10. Repeat Auger Control Test to verify proper adjustment has been achieved.
When selecting a
Drive Speed, use the
slower speeds until
you are comfortable
and familiar with the
operation of the snow
thrower.
NEVER reposition the
shift lever (change
speeds or direction
of travel) without first
releasing the drive
control and bringing
the snow thrower
to a complete stop.
Doing so will result in
premature wear to the
snow thrower’s drive
system.
WARNING
Never use your hands
to clean snow and
ice from the chute
assembly or auger
housing.
The muffler, engine
and surrounding
areas become hot
and can cause a
burn. Do not touch.

Shift Cable
If the full range of speeds (forward and reverse) cannot
be achieved, refer to the figures to the right and adjust
the shift cable as follows:
1. Place the shift lever in the fastest forward speed
position.
2. Loosen the hex nut on the shift cable index bracket.
See Figure 3.
3. Pivot the bracket downward to take up slack in the
cable.
4. Retighten the hex nut.
Drive Control
When the drive control is released and in the disengaged “up” position, the cable should have very little
slack. It should NOT be tight.
Check the adjustment of the drive control as follows:
1. With the drive control released, push the snow
thrower gently forward. The unit should roll freely.
2. Engage the drive control and gently attempt to push
the snow thrower forward. The wheels should not
turn. The unit should not roll freely.
3. With the drive control released, move the shift lever
back and forth between the R2 position and the F6
position several times. There should be no resistance
in the shift lever.
4. If any of the above tests failed, the drive cable is in
need of adjustment. Proceed as follows:
5. Loosen the lower hex nut on the drive cable bracket.
See Figure 4.
6. Position the bracket upward to provide more slack (or
downward to increase cable tension).
7. Retighten the upper hex nut.
Chute Assembly
The distance snow is thrown can be adjusted by changing the angle of the chute assembly. To do so:
1. Stop the engine by removing the ignition key and
loosen the plastic knob found on the left side of the
chute assembly.

Skid Shoes
The space between the skid shoes and the ground can
be adjusted. See Figure 6.
• For close snow removal on a smooth surface, raise
skid shoes higher on the auger housing.
• Use a middle or lower position when the area to be
cleared is uneven, such as a gravel driveway.
To adjust the skid shoes:
1. Loosen the four hex nuts (two on each side) and
carriage bolts. Move skid shoes to desired position.
2. Make certain the entire bottom surface of skid shoe is
against the ground to avoid uneven wear on the skid
shoes.
3. Retighten nuts and bolts securely.

Off-Season
Storage
WARNING
Never store snow thrower
with fuel in tank indoors
or in poorly ventilated
areas, where fuel fumes
may reach an open flame,
spark or pilot light as on
a furnace, water heater,
clothes dryer or
gas appliance.
Fuel left in engine during
warm weather deteriorates
and will cause serious
starting problems.
Preparing Engine
NOTE: Refer to the engine manual for more detailed
information on preparing the snow thrower engine for
storage.
Short-Term Storage
It is important to prevent gum deposits from forming in
essential fuel system parts of the engine such as the
carburetor, fuel filter, fuel hose, or tank during short-term
storage (15-30 days). To prevent this, treat the fuel
system using a fuel stabilizer.
Fuel stabilizer (such as STA-BIL™ or ULTRA-FRESH™)
is an acceptable alternative in minimizing the formation
of fuel gum deposits during storage. Add stabilizer to
gasoline in fuel tank or storage container. Always follow
mix ratio found on stabilizer container. Run engine at least
10 minutes after adding stabilizer to allow it to reach the
carburetor.
WARNING: Never store snow thrower
with fuel in tank indoors or in poorly
ventilated areas, where fuel fumes may
reach an open flame, spark or pilot
light as on a furnace, water heater, clothes dryer or
gas appliance.
CAUTION: Alcohol blended fuels
(called gasohol or using ethanol or
methanol) can attract moisture which
leads to separation and formation of
acids during storage. Acidic gas can damage the fuel
system of an engine while in storage.
Preparing Snow Thrower
• When storing the snow thrower in an unventilated or
metal storage shed, care should be taken to rustproof
the equipment. Using a light oil or silicone, coat the
equipment, especially any chains, springs, bearings
and cables.
• Remove all dirt from exterior of engine and equipment.
• Follow lubrication recommendations.
• Store equipment in a clean, dry area.
Never use engine or carburetor cleaning products in
the fuel tank or permanent
damage may occur.
Long-Term Storage
To avoid engine problems, the fuel system should be
emptied before storage for 30 days or longer.
WARNING: Fuel left in engine during
warm weather deteriorates and will
cause serious starting problems.
1. Run the engine until the fuel tank is empty and it stops
due to lack of fuel. Do not attempt to pour fuel from the
engine.
WARNING: Never use engine or carburetor cleaning products in the fuel tank
or permanent damage may occur.
2. Remove the spark plug and pour one (1) ounce of
engine oil through the spark plug hole into the cylinder.
Cover spark plug hole with a rag and crank the engine
several times to distribute the oil. Replace spark plug.

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.
“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 be defective in materials or workmanship. This limited warranty 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: batteries, 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 441360019, or call 1-800-800-7310 or 1-330-220-4683 or log on to our
Web site at www.mtdproducts.com.
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.
d. Service completed by someone other than an authorized service
dealer.
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.
f. Replacement parts that are not genuine MTD parts.
g. Transportation charges and service calls.
No implied warranty, including any implied warranty of merchantability 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.
IMPORTANT: Owner must present Original Proof of Purchase to obtain
warranty coverage.
