OPERAI=ION
TO USE WEIGHT TRANSFER SYSTEM
In hard packed or heavy snow conditions, conventional
snow throwers tend to ride up and leave uneven mounds of snow behind. For these conditions, your new tracked
snow thrower has a unique weight transfer system (See
Fig,,12) designed to minimize dde-up,.
The weight transfer system engaged shifts more weight to the auger housing. This weight transfer keeps the
snow thrower in contact with the ground and reduces ride-up on ice and snow..
In lighter' snow conditions or when transporting, you should release the weight transfer system for easier
steering.
® To use the weight transfer system, lift up on upper
handle until bracket bolts snap into place in upper slots of weight transfer pedal.
e To release, hold upper handle firmly and push down
on the weight transfer pedal with the ball of your fool
NOTE: The weight transfer system will not work if the auger housing height adjust skids are adjusted to the
highest position
NOTE: Oil must be changed after the first 2 hours of
operation to extend engine life
NOTE: For extreme cold operating conditions of 0°F and below, use a partial synethetic 0W30 motor oil for' easier
starting. ........................

TRACK DRIVE/FREE-WHEEL FEATURE
The track system on your snow thrower has adrive/free_ wheel feature (See Fig, 12A) which allows the unit to be transported easily without the engine being started..
® To use free-wheeling, lift up the loop of the kfick pin
in the front track wheel and pull the pin out Install the pin through the hole in the shaft outside of the track
wheel Repeat on the opposite side of the unit
o To use normal drive, lift the loop of the klick pin from
the outside hole in the shaft.. Rotate the front track wheel until the hole in the track wheel hub and the outside hole in the shaft are in-line Place pin through
the hole in the track hub. Repeat on the opposite side of the unit,.
NOTE: If unit does not move when engine is started,
check the pin locations, Pins on both sides of unit should be in the normal drive position for unit to move,

Fill the fuel tank with clean, fresh, unleaded grade automotive gasoline. Be sure that the container you pour the gasoline from is clean and free from rust or other foreign particles. Never use gasoline that may be stale from long periods of storage in the container.
NOTE: SAE. 5W-30 motor oil may be used to make starting easier in areas where temperature is consis- tentty 20° F or lower.
WARNING: Experience indicates that alcohol blended fuels (called gasohol or those using ethanol or metha- nol) can attract moisture which leads to separation and formation of acids during storage Acidic gas can dam-
age the fuel system of an engine while in storage
To avoid engine problems, the fuel system should be emptied before storage for 30 days or longer Start the
engine and let it run untilt he fuel lines and carbureto rare empty. Use the carburetor bowl drain to empty residual
gasoline from the float chamber (Fig. 41, page 25) Use fresh fuel next season. (See Storage instruclions on
page 25 for additional information) Never use engine or carburetor cleaner products in the
fuel tank or permanent damage may occur.

SNOW THROWING TIPS
® For maximum snow thrower efficiency in removing
snow, adjust ground speed, never the throttle Go slower in deep, freezing, or wet snow. If the track
slips, reduce forward speed. The engine is designed
to deliver maximum performance at full throttle and
should be run at this power setting at all times.
o Most efficient snow blowing is accomplished when
the snow is removed immediately after it falls
e For complete snow removal, slightly overlap each
path previously taken
o The snow should be discharged down wind when-
ever possible.
e For normal usage, set the skids so that the scraper
bar is 1/8" above the skids For extremely hard- packed snow surfaces, adjust the skids upward so
that the scraper bar touches the ground
o On gravel or crushed rock sutraces, set the skids at
t-!/4" below the scraper bar (see To Adjust Skid Height paragraph on page 18) Stones and gravel must not be picked up and thrown by the machine
e If the front of the snow thrower has a tendency to
raise, reduce the ground speed and engage the weight transfer system
o After the snow blowing job has been completed,
allow the engine to idle for a few minutes, which will melt snow and accumulated ice off the engine.
Clean the snow thrower thoroughly after each use
Remove ice and snow accumulation and all debris
from the entire snow thrower, and flush with water
(if possible) to remove all salt or other chemicals
Wipe snow thrower dry
