Weight Transfer System
y^K
FIGURE 9
In hard packed or heavy snow conditions, conventional
snowblowers tend to ride up and leave uneven mounds
of snow behind. For these conditions, your new tracked
snowblower has a unique weight transfer system.
Engaging the weight transfer pedal, shifts the weight of
the snowblower to the auger housing, keeping it in
contact with the ground and effectively reducing ride up.
In lighter conditions or for transport, disengage weight
transfer system.

NOTE: Weight transfer system will not function if auger
housing height adjust skids are adjusted to the lowest
position.
Pre-Use Check of Snowblower
This snowblower is equipped with track drive and only
moves effectively when the engine is running.
If the snowblower must be moved without the aid of the
engine, it will be easier to pull the snowblower by the
handles rather than pushing.
On start up, the drive system may be tight and will
loosen up as the snowblower is used.
After first use, the track should be checked for tension
and adjusted if necessary. See track adjustment. Check
track adjustment and fasteners regularly. (Page 15)
Beforeservicing or startingthe engine, familiarize your
self with the snowblower. Be sure you understand the
function and location of all controls.
Ensure that all fasteners are tight.
To Service Engine
The engine on this snowblowerwas shipped withNO
OIL Oil must be added before engine is started.
1. Remove oil fil cap/dipstick (Figure 11) and fill crank-
case to FULLline on dipstick (about 1-1/4 pints) with
Sears S.A.E. 10W-30 motor oil (or equivalent). Do not
overfill.Tighten fill cap/dipsticksecurely each time
you check oil level. NOTE:Sears S.A.E. 5W-30motor
oil,(Sears stock number 2133531) may be substituted
in areas where temperature is consistently 20° F or
lower.
2. Fill gas tank with clean, fresh, lead-free grade auto
motive gasoline. Low-lead or regular gasoline isan
acceptable substitute. NOTE: Do not use Ethyl, high
octane gasoline or Gasohol. Be certain container 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. CAUTION: DO
NOT use gasoline containing any amount of alcohol
as if can cause serious damage or significantly re
duce performance.
A DANGER A
Gasoline is flammable and caution must be used when
handling or storing it. -Do not fill fuel tank while snow
blower is running, hot, or when snowblower is in an
enclosed area. Keep away from open flame, electrical
spark, and DO NOT SMOKE while filling the fuel tank.
Never fill fuel tank completely; but fill the tank to within
1/4-1/2 inch from the top to provide space for expansion
of fuel. Always fill fuel tank outdoors and use afunnel or
spout to prevent spilling. Make sure to wipe up any
spilled fuel before starting the engine.
Store gasoline in a clean, approved container, and keep
the cap in place on the container. Keep gasoline in a
cool, well ventilated place; never in the house. Never buy
more than a 30 day supply of gasoline to assure volatility.
Gasoline is intended to be used as a fuel for internal
combustion engines; therefore, do not use gasoline for
any other purpose. Since many children like the smell of
gasoline,
keep it out of their reach because the fumes
are dangerous to inhale, as well as being explosive.
3. Check to make sure that spark plug is tightened se
curely into engine and spark plug wire is attached to
spark plug. If torque wrench is available, torque plug
to 15 pounds.

Height Adjust Skid Adjustment
Thissnowblowerisequipped withtwo heightadjust
skids, located on the outside of the blowerhousing.
These elevate the front of the snowblower.
SKID MOUNTING NUTS
HEIGHT ADJUST SKID
FIGURE 19
When removing snow from a hard area such as a paved
drivewayor walk, adjust the skids up to bring the frontof
the snowblower down.
When removing snow from rock on uneven construction,
raise the front of the snowblower by moving the skids
down. This will help to prevent rocks and other debris
from being picked up and thrown by the augers.
To Adjust
1. Place a block (equal to height from ground desired)
under auger housing near but not under skid.
2. Loosen skid mounting nuts (Figure 19) and push the
skid down until it touches the ground. Retighten
mounting nuts.
3.
Set skid on other side at same height. NOTE: Be sure
that snowblower is set at same height on both sides.
A DANGER A
Be certain to maintain proper ground clearance for your
particular area to be cleared. Objects such as gravel,
rocks or other debris, if struck by the impeller auger,
may be thrown with sufficient force to cause personal
Injury, property damage or damage to the snowblower.

Carburetor Adjustment
Never make unnecessary adjustments to the carburetor.
The carburetor was set at the factory to operate efficiently
for most applications (from 0 to 4000 feet above sea
level). However, if adjustments are required, proceed as
follows:
IMPORTANT: When adjusting the carburetor, best re
sults will be obtained if the adjustments are made on a
warm engine. During carburetor adjustments, do not
force screw into the seat. DO NOT remove carburetor
cover. Access holes in cover will allow adjustments to be
made with a screwdriver.
1. Close the high-speed and the idle adjustment needles
finger tight. Do not force. Then open high speed ad
justment needle V/2 turn and idle adjustment needle
V/2 turn (see Figure 33).
2. Start the engine as described in paragraph To Start
Engine.
3. For high speed adjustment move the throttle lever to
FAST position
and then turn the high speed adjusting
needle in or out 1/8 turn at a time until engine runs
smoothly. NOTE: Allow several seconds between
each adjustment for the engine to react to the new
carburetor settings.
4. When the engine is running smoothly, turn the high
speed needle out 1/8 turn counterclockwise. This
may add a slight roughness to the engine which is
advisable for underload operation.
5. For idle adjustment, move the throttle lever to SLOW
position. Turn the idleadjustment needle in or out 1/8
turn at a time until engine idles smoothly. NOTE:
Allow several seconds between each adjustment for
the engine to react to the new carburetor settings.
IDLE
ADJUSTMENT NEEDLE
(CIom finger tight only)
HIGH-SPEED ADJUSTMENT NEEDLE
(Oottflngtr tight only) FIGURE 33
A CAUTION A
Never tamper with engine governorwhich is factory set
for proper engine speed. Over-speeding engine above
factory high speed setting can be dangerous. If you
think the engine governed high speed needs adjusting,
contact your nearest SEARS Service Center who has
the proper equipment and experience to make any ne
cessary adjustments.
IMPORTANT
If the carburetor is adjusted in temperatures above 45° F,
such as in a heated workshop, it may be necessary to set
the carburetor slightly richer. This will compensate for
operation in cold temperatures.
After the carburetor has been adjusted and allowed to
react to the new setting (see Carburetor Adjustment)
open the high speed adjusting needlean additional 1/16
to 1/8 turn.
DO NOT EXCEED 1/8 TURN.
This will add aslight roughness to the engine when run
in temperatures above 45° F.
For
best results, carburetor adjustments should be made
in temperatures that the snowblower will be most used
in.
Engine Servicing
For any major engine adjustment or servicing during the
engine warranty period, contact your nearest Sears Ser
vice Dept.
For prompt and efficient sen/ice, please furnish the en
gine model, type and trim number of your engine.

STORAGE
Off-Season Storage
If the snowblower isto be stored for thirty (30) days or
more or at the end of the snow season, the following
stepsare recommended to prepare your snowblowerfor
storage.
1. Thoroughly clean the snowblower.
2. Drain the gasoline from the fuel tank by removing
the fuel line at the fuel shut-off valve.
NO TE: Close fuel shut-off valve before removing the
fuel line. Allow gasoline to drain into a container.
Replace the fuel line to the fuel shut-off valve.
WARNING: Drain gasolineoutdoors away from fire
or flame.
3. Startthe engineand runat SLOW speed (idle) until
the engine stops from fuel exhaustion. Fuel tank,
fuel linecarburetor, and the engine should now be
free from gasoline.
4. Remove the spark plug and squirt one (1)ounce of
engine oil into the cylinder. Pull the recoil starter
rope slowly which will allow the piston to coat the
internal engine parts. Install an old spark plug; this
preventsfouling a new plug with the preservative
used to lubricate the internal parts of the engine.
Close thechokeand plug the muffler opening.
5. Lubricate alllubrication points (see Lubrication).
6. Insure that all nuts, bolts, and screws are securely
fastened. Inspect all visible moving partsfor damage,
breakage,and wear. Replace ifnecessary.
7. Touch up all rusted or chipped paint surfaces; sand
lightly before painting.
8. Coverthe bare metalparts ofthe blowerhousing
auger, and the impeller with rust preventative.
9. If possible, store your snowblower indoors and cover
it to give protection from dust and dirt.
10. If the machine must be stored outdoors, blockup
the snowblower and insure the entire machine is off
theground.Coverthe snowblower with a heavy tar
paulin.
A DANGER A
Never store engine with fuel in tank indoors or in enclos
ed, poorly ventilated enclosures, where fuel fumes may
reachan open flame, spark or pilotlightas on a furnace,
water heater, clothes dryer, etc.
Handle gasoline carefully. Itis highly flammable and
careless use could resultinserious fire damage to your
person and/or property.
Drain fuel into approved containers outdoors, away from
open flame.

Operating Tips
1. Foroptimumsnowblowerefficiency, adjust ground
speed, not the throttle. REMEMBER — if the track
slips forward speed should be reduced.
2. Mostefficient snowblowing isaccomplished when
snow is removed immediately after it falls.
3. Forcompletesnow removal,slightlyoverlapeach
swath previously taken.
4. Snow should be discharged downwind whenever
possible.
5. For normal usage,settheskidsoneeighthinch below
thescraper bar.Forextremely hard-packedsnowsur
faces, the skids may be adjusted upward to insure
cleaning efficiency.
6. On gravel or crushed rock surfaces, the skids should
be set at one-fourth inch belowthe scraper bar (see
Adjusting Skids, page 12). Rocks and gravel must
not be picked up and thrown by the machine.
7. If the frontofthe snowblowerhas a tendency to rise,
reduce the ground speed and engage weighttrans
fer system.
8. Afterthe snowblowing job has been completed, al
low the engine to idle for a few minutes, which will
meltsnow and ice accumulated offthe engine.
9. Remove ice and snow accumulation from the entire
snowblowerto prevent obstructions and possible
damage when snowblower issubsequentlyoper
ated.
