SERVICE AND ADJUSTMENTS
TO ADJUST SKID HEIGHT
This snow thrower is equipped with two height adjust-
ment skids, located on the outside of the auger housing
(See III.20). These skids elevate the front of the snow
thrower.
For normal hard surfaces, such as a paved driveway or
walk, adjust the skids as follows:
● Check both tires for equal inflation. Correct tire
pressure is 14 to 17 pounds. Do not exceed sidewall
maximum pressure on tire.
● Place the extra shear bolts supplied (found in parts
bag) under each end of the scraper bar near but not
under the skid.
● Loosen the skid mounting nuts (See III.20), and
adjust the skids up to bring the front of the snow
thrower down. Re-tighten the mounting nuts.
● Set the skid on the other side at the same height.
NOTE: For rocky or uneven surfaces, raise the front of
the snow thrower by moving the skids down. This will
help prevent rocks and other debris from being picked up
and thrown by the auger.
TO ADJUST SCRAPER BAR
After considerable use, the metal scraper bar will have
a definite wear pattern. The scraper bar in conjunction
with the skids should always be adjusted to allow 1/8"
between the scraper bar and the sidewalk or area to be
cleaned.
● Position the snow thrower on a level surface.
● Make sure both tires are equally inflated. Proper tire
pressure is 14 to 17 PSI. See side of tire for maxi-
mum inflation. Do not exceed sidewall maximum
pressure on tire.
● Loosen the carriage bolts and nuts securing the
scraper bar to the auger housing.
● Adjust the scraper bar to the proper position.
● Tighten the carriage bolts and nuts, making sure that
the scraper bar is parallel with the working surface.
● For extended operation, the scraper bar may be
reversed. If the scraper bar must be replaced due to
wear, remove the carriage bolts and nuts and install
a new scraper bar.
ALWAYS DISCONNECT THE SPARK
PLUG WIRE AND TIE BACK AWAY FROM
THE PLUG BEFORE MAKING ANY
ADJUSTMENTS OR REPAIRS.
BE CERTAIN TO MAINTAIN PROPER
GROUND CLEARANCE FOR YOUR PAR-
TICULAR AREA TO BE CLEARED. OB-
JECTS SUCH AS GRAVEL, ROCKS OR
OTHER DEBRIS, IF STRUCK BY THE
IMPELLER, MAY BE THROWN WITH SUF-
FICIENT FORCE TO CAUSE PERSONAL
INJURY, PROPERTY DAMAGE OR
DAMAGE TO THE SNOW THROWER.
TO ADJUST THE CLUTCH CONTROL
CABLES
Periodic adjustment of the cables may be required due to
normal stretch and wear on the belts. To check for correct
adjustment, the control lever must be in the full forward
position, resting on the plastic bumper. The control cables
are correctly adjusted when the center of the "Z" Fitting is
between the center and top of the hole in the clutch lever
and there is no droop in the cable (See III.21).
If adjustment is necessary:
● Remove gas from gas tank. Stand blower on end.
● Disconnect the “Z” Fitting from drive lever.
● Pull spring cover up to expose spring. Push the cable
through the spring (See III.22) to expose the threaded
portion of the cable.
● Hold the square end of the threaded portion with
pliers and adjust the locknut in until the excess slack
is removed (See III 22 INSET).
● Pull the cable back through the spring and connect
the cable. Do the same for the other lever cable.
NOTE: Whenever the traction drive or auger belts are
adjusted or replaced, the cables will need to be adjusted.
TO ADJUST BELTS
Belts stretch during normal use. If you need to adjust the
belts due to wear or stretch, proceed as follows:
AUGER DRIVE BELT
(See III.24)
If your snow thrower will not discharge snow, check the
control cable adjustment. If it is correct, then check the
condition of the auger drive belt. It may be loose or
damaged. If it is damaged, replace it. (See To Replace
Belts paragraph in this section). If the auger drive belt
is loose, adjust as follows:
● Disconnect the spark plug wire.
● Remove the belt cover (See III.25).
● Loosen the nut on the auger idler pulley (See III.23)
and move the pulley toward the belt about 1/8".
● Tighten the nut.
