TO ADJUST SKID PLATES (See Fig. 18)
NOTE: The wrench provided in your parts bag may be
used to adjust the skid plates.
Skid plates are located on each side of the auger housing
and adjust the clearance between the scraper bar and the
ground surface. Adjust skid plates evenly to proper height
for current surface conditions.
For removal of snow in
normal conditions, such as a paved driveway or sidewalk,
place skid plates in the highest position (lowest scraper
clearance) to gwe a 1/8" clearance between the scraper
bar and the ground.
Use a middle position if the surface
to be cleared is uneven.
NOTE: It is not recommended to operate the snow thrower
over gravel or rocky surfaces. Objects such as gravel, rocks
or other debris, can easily be picked up and thrown by the
impeller, which can cause serious personal injury, property
damage or damage to the snow thrower.
If snow thrower must be operated over gravel surface,
use extra caution and be sure skid plates are adjusted
to lowest (highest scraper clearance) position.
1.
Shut off engine and wait for all moving parts to stop.
2.
Adjustskid plates by loosening the hex nuts, then mov-
ing skid plate to desired position. Be sure both plates
are adjusted evenly. Tighten securely.

SCRAPER BAR (See Fig. 18)
The scraper bar is not adjustable, but is reversible.
After
considerable use it may become worn. When it has worn
almost to the edge of the housing, it can be reversed,
providing additional service before requiring replacement.
Replace a damaged or worn scraper bar.
BEFORE
STARTING
THE ENGINE
CHECK ENGINE OIL LEVEL (See Fig. 19)
The engine on your snow thrower has been shipped, from
the factory, already filled with oil.
1.
Check engine oil with snow thrower on level ground.
2.
Remove oil fill cap/dipstick and wipe clean, reinsert
the dipstick and screw tight, wait for a few seconds,
remove and read oil level. If necessary, add oil until
"FULl" mark on dipstick is reached. Do not overfill.
To change engine oil, see "TO CHANGE ENGINE OIL['
in the Maintenance section of this manual.
ADD GASOLINE (See Fig. 19)
Fill fuel tank to bottom of tank filler neck. Do not over-
fill. Use fresh, clean, regular unleaded gasoline with
a minimum of 87 octane. Do not mix oil with gasoline.
Purchase fuel in quantities that can be used within 30
days to assure fuel freshness.
WARNING:
Wipe off any spilled oil or
fuel. Do not store, spill or use gasoline
near an open flame.
CAUTION: Alcohol blended fuels (called gasohol
or using ethanol or methanol)
can attract mois-
ture 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 of 30 days or longer.
Drain the gas tank, start the engine and let it run
until the fuel lines and carburetor are empty. Use
fresh fuel next season. See Storage instructions
for additional
information.
Never use engine or
carburetor cleaner products in the fuel tank or
permanent damage may occur.
