adjusting the angle of the chute assembly. Refer to
Chute Tilt Control on page 6.

The remote chute control cables have been pre­adjusted at the factory. Move the remote chute lever on
the control panel back and forward to adjust angle of
the chute assembly.

Tire Pressure (Pneumatic Tires)

The tires are overinflated for shipping purposes.

• Check the tire pressure before operating the snow
thrower. Refer to the tire side wall for tire
manufacturer’s recommended psi and deflate (or
inflate) the tires as necessary.

NOTE: If the tire pressure is not equal in both tires, the
unit may pull to one side or the other.

11

WARNING: Maximum tire pressure under

any circumstance is 30 psi. Equal tire pressure
should be maintained at all times. Excessive
pressure (over 30 psi) when seating beads
may cause tire/rim assembly to burst with
force sufficient to cause serious injury

Skid Shoe Adjustment

The space between the shave plate and the ground can
be adjusted by raising or lowering the skid shoes.

For close snow removal, as when using on a smooth
concrete or asphalt driveway, place the skid shoes in
the low position. Use the middle or high position when
the area to be cleared is uneven. When operating on
gravel, always put skid shoes in the high position.
See Figure 11.

Adjust skid shoes as follows:

• Loosen, but do not remove, the three hex nuts
which fasten the skid shoe to the auger housing.

• Raise or lower the skid shoe to desired position.

• Retighten the hex nuts loosened earlier.

• Repeat on the other side of the snow thrower.

The limited warranty set forth below is given by Troy-Bilt LLC
with respect to new merchandise purchased and used in the
United States, its possessions and territories.

Troy-Bilt LLC warrants this product against defects 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 accessory or attachment not approved by Troy-Bilt
LLC for use with the product(s) covered by this manual will
void your warranty as to any resulting damage.

Normal wear parts or components thereof are subject to
separate terms as follows: All normal wear parts or
component failures will be covered on the product for a period
of 90 days regardless of cause. After 90 days, but within the
two year period, normal wear part failures will be covered
ONLY IF caused by defects in materials or workmanship of
OTHER component parts. Normal wear parts and
components include, but are not limited to: 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 Troy-Bilt LLC at P.O. Box 361131,
Cleveland, Ohio 44136-0019, or call 1-866-840-6483 or 1­330-558-7220, or log on to our Web site at www.troybilt.com.

This limited warranty does not provide coverage in the
following cases:

a. The engine or component parts thereof. These items

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 sepa-

rate 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. Troy-Bilt LLC does not extend any warranty for

products sold or exported outside of the United States,
its possessions and territories, except those sold
through Troy-Bilt LLC’s authorized channels of export
distribution.

e. Parts that are not genuine Troy-Bilt parts are not

covered by this warranty.

f. Service completed by someone other than an

authorized service dealer is not covered by this
warranty.

g. Transportation charges and service calls are not

covered.

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 Troy-Bilt LLC. 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. Troy-Bilt
LLC 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.

limited warranty gives you specific legal rights, and you may
also have other rights which vary from state to state.
