Electric Starter: (If Equipped)

WARNING: The electric start er is

equipped with a three-wire power cord and
plug, and is designed to oper ate on 120 volt
AC household current. It must be properly
grounded at all times to avoid the possibility
of electric shock which may be injurious to
the operator. Follow all instructions carefully.
If the house wiring system is not a three-wire
grounded system, do not use this ele ctric
starter under any conditions.

Follow all instructions carefully. Determine that your
house wiring is a three wire grounded system. Ask a
licensed electrician if you are not certain. If your house
wiring system is not a three-wire grounded system, do
not use this electric starter under any condit ions. If your
system is grounded and a three-hole recept acle is not
available at the point your starter will normally be used,
one should be installed by a licensed electrician.

When connecting the power cord, always connect cor d
to starter on engine first, then plug the othe r end into a
three-hole grounded receptacle.

When disconnecting the power cord, always unplug the
end from the three-hole grounded receptacle fir st.

SECTION 6: MAKING ADJUSTMENTS

WARNING: Muffler, engin e and

surrounding areas become hot and can
cause a burn. Do not touch.

• For most efficient snow remova l, remove s now
immediately after it all falls.

• Discharge snow downwind whenever possible.
Slightly overlap each previous swath.

• Set the skid shoes 1/4” below the scraper bar for
normal usage. The skid shoes may be adjusted
upward for hard-packed snow. Adjust downward
when using on gravel or crushed rock.

• Be certain to follow the precautions listed under “To
Stop Engine” in previous column to prevent
possible freeze-up.

• Clean the snow thrower thoroughly after each use.

WARNING: NEVER attempt to make any

adjustments while the engine is running,
except where specified in the operator’s
manual.

Adjusting Chute

You can control the distance that snow is thrown by
adjusting the angle of the chute assembly. The sharper
the angle, the shorter the distance snow is thrown.

• To adjust the chute, loosen the hand knob. See

MANUFACTURER’S

LIMITED WARRANTY

The limited warranty set forth below is given by MTD
PRODUCTS INC (“MTD”) 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
material 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 MTD Products Inc. for use with the product(s)
covered by this manual will void your warranty as to any
resulting damages.

Normal wear parts or components thereof are subject to
separate terms as follows: All normal wear part or comp o­nent 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 par t failures will be covered
ONLY IF caused by defects in material or workmanship of
OTHER component parts. Normal wear par ts and compo­nents include, but are not limited to, belts, blades, blade
adapters, grass bags, rider deck wheels, seats, snow
thrower skid shoes, shave plates and tires. Batteries are
covered by a 90-day limited replacement warranty.

HOW T O OBTAIN SERVICE: Warranty service is availab le,

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

to the applicable manufacturer’s warranty on these
items.

b.Log splitter pumps, valves and cylinders have a sepa-

rate one year warranty.

c. Routine maintenance items such as lubricants, filters,

as brake adjustments, clutch adjustments or deck
adjustments; and normal deterioration of the exterior
finish due to use or exposure.

d. MTD does not extend any warranty for products sold

or exported outside of the United States of America,
its possessions and territories, except those sold
through MTD’s authorized channels of export distribu­tion.

No implied warranty, including any implied warranty of
merchantability or 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 or guaranty, 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. (Some states do not

or damages including, without limitation, expenses
incurred for substitute or replacement lawn care ser­vices, for transportation or for related expenses, or for
rental expenses to temporarily replace a warranted
product. (Some states do not allow the exclusion or limita-

tion of incidental or consequential damages, so the above
exclusion or limitation 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 the 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 arisin g out of the use or misuse or inability to use
the product.

This limited warranty shall not extend to anyone other than

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