ALL moving parts to stop before re-adjusting the auger
control.
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.
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.
WARNING
Never use your hands
to clean snow and
ice from the chute
assembly or auger
housing.
To Engage Drive
1. With the throttle control in the Fast (rabbit) position,
move shift lever into one of the six forward (F)
positions or two reverse (R) positions. Select a speed
appropriate for the snow conditions and a pace you’re
comfortable with.
The muffler, engine
and surrounding
areas become hot
and can cause a
burn. Do not touch.
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

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.
Drain fuel into an
approved container
outdoors, away from
any open flame. Be
certain engine is
cool. Do not smoke.
Fuel left in engine
during warm weather
deteriorates and will
cause serious
starting problems.
If the snow thrower will not be used for 30 days or longer,
or if it is the end of the snow season when the last possibility of snow is gone, the equipment needs to be stored
properly. Follow storage instructions below to ensure top
performance from the snow thrower for many more years.
1. Remove all gasoline from the carburetor and the fuel
tank to prevent gum deposits from forming on these
parts and harming the engine.
Preparing Engine
3. Drain carburetor by pressing upward on bowl drain,
located below the carburetor cover (refer to the
Tecumseh engine manual for more detailed instruction).
2. Run the engine until the fuel tank is empty and it stops
due to lack of fuel.
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.
WARNING: Do not drain carburetor if using fuel stabilizer. Never
use engine or carburetor cleaning
products in the fuel tank or
permanent damage may occur.
NOTE: 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 storage.
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.
To avoid engine problems, the fuel system should be
emptied before storage for 30 days or longer. Follow
these instructions to prepare your snow thrower for
storage:
WARNING: Drain fuel into an approved container outdoors, away
from any open flame. Be certain
engine is cool. Do not smoke.
Fuel left in engine during warm
weather deteriorates and will
cause serious starting problems.
NOTE: Fuel stabilizer (such as STA-BIL) 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. Do not
drain carburetor if using fuel stabilizer.
4. 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.
NOTE: Refer to the Tecumseh engine manual for more
information on preparing the snow thrower engine for
storage.
Preparing Snow Thrower

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 44136-0019, 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.
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.
d. Service completed by someone other than an authorized service
dealer.
