HAZARD
• In certain conditions gasoline is extremely
flammable and highly explosive.
WHAT CAN HAPPEN
• A fire or explosion from gasoline can burn
you, others, and cause property damage.
HOW TO AV
OID THE HAZARD
• Use a funnel and fill the fuel tank outdoors,
in an open area, when the engine is cold.
Wipe up any gasoline that spills.
• Do not fill the fuel tank completely full.
Add gasoline to the fuel tank until the level
is 1/4” to 1/2” (6 mm to 13 mm) below the
bottom of the filler neck. This empty space
in the tank allows gasoline to expand.
• Never smoke when handling gasoline, and
stay away from an open flame or where
gasoline fumes may be ignited by a spark.
• Store gasoline in an approved container
and keep it out of the reach of children.
• Never buy more than a 30-day supply of
gasoline.
Toro Two–Cycle Oil is specially formulated to
provide superior lubrication, make starting easy,
and prolong engine life. If Toro T
is not available, mix two gallons of gasoline and
5.2 ounces of another high grade two–cycle oil
that has the NMMA or BIA–TCW III
certification printed on the label.
NEVER USE AUTOMOTIVE OIL (i.e. SAE
30, 10W30 etc.), TWO–CYCLE OIL THAT IS
NOT CERTIFIED NMMA/BIA–TCW III, OR
THE WRONG MIX RATIO BECAUSE THE
ENGINE CAN BE DAMAGED, AND IT
WOULD NOT BE COVERED BY THE TORO
WARRANTY.
2. Mixing Gasoline and Oil—Pour a half gallon of
gasoline into an approved gasoline container
(preferably plastic, not metal) and add the correct
amount of two–cycle oil. Reinstall cap on
gasoline container and shake the container to
mix oil and gas thoroughly. Remove cap and add
remaining amount of gasoline.
Toro also recommends that Toro
Stabilizer/Conditioner be used regularly in all
Toro gasoline powered products during operation
and storage seasons. Toro Stabilizer/Conditioner
cleans the engine during operation and prevents
gum–like varnish deposits from forming in the
engine during periods of storage.
wo–Cycle Oil
Mix
Gasoline And Oil (Fig. 1
Use clean, fresh lead-free gasoline, including
oxygenated or reformulated gasoline, with an octane
rating of 85 or higher. To ensure freshness, purchase
only the quantity of gasoline that can be used in 30
days. Use of lead-free gasoline results in fewer
combustion chamber deposits and longer spark plug
life. Use of premium grade fuel is not necessary or
recommended.
1. APPROVED OIL—For simplicity and best
engine performance, mix the contents of one
5.2–ounce bottle of Toro 50:1 T
with two gallons of fresh, unleaded regular
gasoline.

of the snow stream. Do not overtighten the chute
deflector mounting nuts so excessive force is
required to adjust the deflector.
IMPORTANT: Do not use chute handle to lift
snowthrower; damage to chute handle could
result.
POTENTIAL HAZARD
• Stones, toys and other foreign objects may
be picked up and thrown by the rotor
blades.
ADJUSTING DISCHARGE CHUTE

crank clockwise to move discharge chute to the
right and counterclockwise to move chute to the
left. The chute deflector handle on top of the
discharge chute controls the height of the snow
stream. Do not overtighten the chute deflector
mounting nuts so excessive force is required to
adjust the deflector.
2.
SELF–PROPELLING ACTION
snowthrower clears down to the ground and
propels itself forward when the handle is raised
and the snowthrower is tilted slightly forward so
rotor blades strike the ground. The wheels do not
have to touch the ground in order to self-propel.
The further you tilt the handle forward, the faster
the snowthrower self-propels. However, height
and density of snow affects forward speed.
Always overlap each swath and discharge
downwind whenever possible.
3. Keep the area to be cleared free of stones, toys or
other foreign objects which may be picked up
and thrown by the rotor blades. Such items could
be covered by snowfall and, therefore, unnoticed
until struck by the rotor blades. Always be sure
to keep children and pets away from area of
operation.

HOW TO AV
OID THE HAZARD
• Keep the area to be cleared free of all
objects that could be picked up and thrown
by rotor blades.
• Keep all children and pets away from area
of operation.
4. Should you find it necessary to clear snow from
crushed rock or gravel, push down on handle to
raise rotor blades clear of loose material that
could be thrown by the blades and push unit
forward.

4. After extended use the drive belt may wear and
proper belt tension may not be maintained.
Improper belt tension causes belt slippage and
decreases the snowthrower
a heavy load. Belt slippage may occur after 2–3
seasons of normal usage (10–15 hours). If drive
belt slips (continuous squealing noise) under
heavy load, increase belt tension by:

spring end in bottom hole in control bar
bracket (Fig. 8).
B. Models 38433 & 38438 – repositioning

bar bracket (Fig. 10).
Readjust cable (see steps 2–3).
IMPORTANT: Unnecessary use of forward or
bottom adjusting hole in control bar bracket
reduces drive belt life. Occasional belt slippage
(squealing) may occur in extremely wet
conditions due to moisture in drive system. To
remove moisture, start rotor and operate under
no load for 30 seconds. Once moisture is
removed, belt should not slip.

Adjusting
The carburetor has been factory set, and no
adjustment is required.
Replacing
Before each snow season, inspect rotor blades for
wear. When blade edge has worn to the wear indicator
hole (Fig. 23), the blades must be replaced to ensure
proper performance and prevent damage to underside
of snowthrower. Always replace both blades at the
same time.
Note: Whenever rotor blades are replaced,
Carburetor
Rotor Blades
scraper should also be replaced to
ensure proper snowthrower operation
and performance.
Page 23
Note: Rotor blades wear rates are determined
by the running time and the roughness
of the driveway or sidewalk.
Storage
1. FUEL SYSTEM PREPARATION–
Removing Old Blade
1. Remove (4) torx screws and (4) lock nuts
securing outer edges of rotor blade to rotor shaft
assembly (Fig. 24).
2. Next, remove (2) hex–head capscrews, spacers
and lock nuts securing center of blade to rotor
halves (Fig. 24).
3. Loosen the hex–head screw securing the rotor
halves to the auger shaft assembly (Fig. 24).
4. Slide the blade out from between the rotor halves
(Fig. 24).
Installing New Blade
1. The rotor blades are made of laminated rubber.
Examine the edge of a blade to see the difference
in layer thicknesses (Fig. 25). (Some blades have
a part number on the thick side of the blade.)
Note: A fuel stabilizer/conditioner is most
effective when mixed with fresh
gasoline.
• Add Toro Stabilizer/Conditioner to the fuel tank
(one ounce per gallon of fuel).
• Run engine for five minutes to distribute
conditioned fuel through fuel system.
• Stop engine, allow it to cool, and drain fuel tank.
• Restart the engine again and run it until it stops.
• Either choke or prime the engine, restart it a
third time and run engine until it will not restart.
• Dispose of fuel properly. Recycle per local
codes.
• DO NOT store ST
days.
2. CYLINDER/PISTON CARE—Slowly pull
recoil starter until resistance is felt due to
compression pressure, then stop. Release starter
tension slowly to prevent engine from reversing
due to compression pressure. This position
closes both the intake and exhaust ports which
prevents corrosion of the cylinder bore.
ABILIZED gasoline over 90
Both blades must be installed with the thick
layer on the inside of the curve. If one blade is
installed with the thick layer on the outside of
the curve and the other blade installed with the
thick layer on the inside of the curve, the blades
will be unbalanced, causing the snowthrower to
“hop” or “bounce.”
2. Insert the new blade between the rotor halves.
Secure it to the rotor halves with (2) hex–head
capscrews, (2) spacers and (2) lock nuts
(Fig. 24). Position bolt heads on thick (bottom)
side of blade. Curve the blade, and secure it with
the remaining (4) torx screws and lock nuts
(position screw heads on thick side of blade).
Tighten all screws and nuts securely.
3. TIGHTEN FASTENERS AND
CLEAN—Tighten screws, bolts, and nuts if
necessary. Repair or replace damaged parts.
Clean unit thoroughly.
