Refer to Maintenance section.
4. Remove the spark plug and squirt one ounce of
clean engine oil into spark plug hole. Cover the
spark plug hole with a clean rag. Pull the starter
rope slowly to allow the piston to coat the internal
engine parts. Reinstall the spark plug. Do not con­
nect spark plug wire.

ADJUSTMENTS/REPAIRS
\ WARNING {
Always stop engine and disconnect spark
plug wire before performing any
adjustments or repairs.
SKID SHOE ADJUSTMENT
The snow thrower is equipped with two adjustable skid
shoes, located on each side of the auger housing. The
skid shoes determine the distance between the scraper
bar and the ground, which varies according to the type
of surface to be cleared.
Normal, Hard Surfaces
When removing snow from a normal, hard surface such
as a paved driveway or walk, the skid shoes should be
adjusted to be approximately 1/4" lower than the
scraper bar.
To adjust, proceed as follows.
1. Make certain both tires are inflated equally (15 to
20 psi), and that neither tire is resting on a link of
the tire chains.
2. Place the threaded ends of the spare shear bolts
(provided in hardware pack) under the scraper bar,
one at each end. See figure 25.
3. Loosen the four hex nuts on the skid shoes. Push
each skid shoe up or down until it touches the
ground. Retighten the hex nuts securely.
Make certain the snow thrower is set at the same height
on both sides, and the entire bottom surface of skid
shoe is against the ground to avoid uneven wear.
Uneven or Rocky Surfaces
When removing snow from uneven, rocky or gravel sur­
faces, raise the scraper bar by moving the skid shoes
down to avoid throwing gravel. Adjust as instructed
above, using thicker objects under the scraper bar to
act as spacers.
■i^NOTE
Both the skid shoes and the shave
plate are subject to wear and should
be replaced when necessary.

SPEED SELECT LEVER ADJUSTMENT
If adjustment of the speed select lever is necessary,
remove the hairpin clip which secures the shift rod to
the speed select lever. Adjust as instructed under “At­
taching the Shift Rod” in Assembly Instructions, page
7.
TRACTION DRIVE CLUTCH LEVER ADJUSTMENT
Periodic adjustment of the traction drive cable may be
required due to normal wear on the friction wheel. If
adjustment is necessary, unhook the spring on the end
of the traction drive cable. Refer to figure 13. Adjust
as instructed in steps 2 and 3 of “Attaching the Trac­
tion Drive Cable” in Assembly Instructions, page 8.
AUGER DRIVE CLUTCH LEVER ADJUSTMENT
The auger drive cable should be adjusted at least once
a season. To adjust the auger cable, remove the fer­
rule from the auger bracket by removing the cotter pin
and flat washer. Refer to figure 15. Adjust as instructed
in steps 2 and 3 of “Attaching the Auger Cable” in
Assembly Instructions, page 9.
