Read this manual carefully to learn how to operate
and maintain your product correctly. Reading this
manual will help you and others avoid personal injury
and damage to the product. Although Toro designs,
produces and markets safe, state-of-the-art products,
you are responsible for using the product properly
and safely. You are also responsible for training
persons who you allow to use the product about safe
operation.
The Toro warning system in this manual identifies
potential hazards and has special safety messages that
help you and others avoid personal injury, even death.
DANGER, WARNING and CAUTION are signal
words used to identify the level of hazard. However,
regardless of the hazard, be extremely careful.
DANGER signals an extreme hazard that will cause
serious injury or death if the recommended
precautions are not followed.
1
WARNING signals a hazard that may cause serious
injury or death if the recommended precautions are
not followed.
Gasoline is highly flammable; handle it carefully.
• Do not smoke while handling gasoline.
CAUTION signals a hazard that may cause minor or
moderate injury if the recommended precautions are
not followed.
Two other words are also used to highlight
information. “Important” calls attention to special
mechanical information and “Note” emphasizes
general information worthy of special attention.
The left and right side of the machine is determined
by standing behind the handle in the normal
operator’s position.
Safety
Read and understand this Operator’s Manual before
using the backpack blower. Be thoroughly familiar
with the proper use of the backpack blower.
Never allow children to operate the backpack blower.
It is not a toy. Never allow adults to operate the unit
without first reading the Operator’s Manual.
Become familiar with the controls and know how to
stop the engine quickly.
Always use eye protection and ear protection.
• Use an approved fuel container for storing the
gasoline/oil mixture.
• Do not fill the fuel tank when the engine is hot
or running.
• Fill the fuel tank outdoors and only up to
one-half inch from the top of the tank. Do not
fill the filler neck.
• Wipe away any spilled gasoline before starting
the engine.
Always be sure of your footing; keep a firm hold of
the blower pipes, and walk, never run, while
operating the backpack blower.
Use the correct accessories. Do not use the backpack
blower for any job except that for which it is
intended.
Keep all fasteners tight and be sure the backpack
blower is in safe working condition. Follow the
maintenance instructions in this manual.
Do not put hands or feet near or under the rotating
parts. Keep clear at all times.
Keep the area of operation clear of all persons,
particularly small children, and pets.
Do not point blower nozzle in the direction of people
or pets.
Never operate the backpack blower when you are
fatigued.
Never operate the backpack blower without proper
guards or other protective safety devices in place.
Dress properly; do not wear loose clothing or jewelry
that can be caught in moving parts. Always wear
substantial footwear, long pants, and a long-sleeved
shirt.
If the backpack blower should start to vibrate
abnormally, stop the engine immediately and check
for the cause. Vibration is generally a warning of
trouble.
Avoid using the backpack blower near rocks, gravel,
stones, and similar matter to avoid dangerous flying
debris. Use the backpack blower only in daylight or
good artificial light.
Do not allow bystanders in work area.
Do not operate without guard(s) in place.
Do not operate in unventilated area.

Assembly
1. Locate and identify all the components (Fig. 1)
2. Using the bands, connect the flexible pipe to the
blower, and the swivel pipe to the flexible pipe
(Fig. 6).
3. Assemble the straight pipe and bent pipe. Then
connect them to the swivel pipe (Fig. 6).
Before Starting
POTENTIAL 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 AVOID 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.
Mix Gasoline And Oil (Fig. 5)
Use clean, fresh lead-free gasoline, including
oxygenated or reformulated gasoline, with an octane
rating of 87 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 Two–Cycle Oil
with two gallons of fresh, unleaded regular
gasoline. Leaded regular gasoline may be used if
unleaded regular is not available.
Toro Two–Cycle Oil is specially formulated to
provide superior lubrication, make starting easy,
and prolong engine life. If Toro Two–Cycle Oil
is not available, mix two gallons of gasoline and
5.2 ounces of another high grade two–cycle oil
that is specially formulated for
high-performance, two-cycle air-cooled engines.
NEVER USE AUTOMOTIVE OIL (i.e. SAE
30, 10W30 etc.), TWO–CYCLE OIL THAT IS
CERTIFIED NMMA OR BIA, 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.
3
IMPORTANT: NEVER USE METHANOL,
GASOLINE CONTAINING METHANOL,
GASOHOL CONTAINING MORE THAN
10% ETHANOL, PREMIUM GASOLINE,
OR WHITE GAS BECAUSE THE ENGINE
AND FUEL SYSTEM COULD BE
DAMAGED.
DO NOT USE FUEL ADDITIVES OTHER
THAN THOSE MANUFACTURED FOR
FUEL STABILIZATION DURING
STORAGE SUCH AS TORO’S
STABILIZER/CONDITIONER OR A
SIMILAR PRODUCT. TORO’S
STABILIZER/CONDITIONER IS A
PETROLEUM DISTILLA TE BASED
CONDITIONER/STABILIZER. TORO
DOES NOT RECOMMEND STABILIZERS
WITH AN ALCOHOL BASE SUCH AS
ETHANOL, METHANOL OR ISOPROPYL.
ADDITIVES SHOULD NOT BE USED TO
TRY TO ENHANCE THE POWER OR
PERFORMANCE OF THE MACHINE.
Note: Do not mix gasoline and oil in the
product fuel tank. Oil that is at room
temperature mixes easier and more
thoroughly than cold oil.

Operation
When the backpack blower is positioned on the back
of the operator, the throttle lever is located on the left
side of the operator (Fig. 3).
The lowest position of the throttle lever is the “IDLE”
setting, and the highest position is the “FULL
THROTTLE” setting (Fig. 4).
Starting Engine
1. Pump the primer bulb on the side of the
carburetor until you see fuel flowing through the
fuel-return line (Fig. 7).
2. Move the choke lever fully downward to the
closed position (Fig. 8). If the engine is already
warm, only a partial or open (no choke) choke
setting may be required.
3. Turn the stop switch ON (Fig. 9). (Confirm that
the stop switch is in the START position.)
4. Set the throttle lever at 1/2 speed (Fig. 9).
5. Pull the starter grip briskly to start the engine
(Fig. 10).
Note: Only short pulls are necessary. Never
pull the starter cord to its fullest
extension. Never let go of the starter
grip until it is at the fully returned
position.
6. Warming up the engine. When the engine has
started, slowly move the choke lever fully
upward to the open position (Fig. 11). Allow the
engine to warm up at less than 1/2 speed.
See Figure 6 for the location of major backpack
blower components.
Throttle Lever
Before operating the backpack blower, release the
knob, rotate the throttle arm to the position in
Figure 2, and tighten the knob.
Stopping Engine
7. Always run the engine at idle speed for a few
minutes to allow cooling before stopping.
8. To stop the engine, move the throttle control
lever all the way downward to the engine idle
position. Then move the stop switch to the
STOP position (Fig. 9).
