Engine Controls
Choke Lever
Use the choke lever (Figure 16) to start a cold engine.
Before pulling the recoil-start handle, move the choke
lever to the CLOSED position. Once the engine is
running, move the choke lever to the OPEN position.
Do not use the choke if the engine is already warmed
up or if the air temperature is high.
Throttle Lever
The throttle lever (Figure 16) controls the speed (rpm)
of the engine. It is located next to the choke lever. It
sets the engine speed and therefore can increase and
decrease the rotation speed of the mixing paddles.
For best performance, set this control to the FAST
position when mixing material.

30 days old), unleaded gasoline with an octane
rating of 87 or higher ((R+M)/2 rating method).
• Ethanol: Gasoline with up to 10% ethanol
(gasohol) or 15% MTBE (methyl tertiary butyl
ether) by volume is acceptable. Ethanol and
MTBE are not the same. Gasoline with 15%
ethanol (E15) by volume is not approved for use.
Never use gasoline that contains more than
10% ethanol by volume, such as E15 (contains
15% ethanol), E20 (contains 20% ethanol), or E85
(contains up to 85% ethanol). Using unapproved
gasoline may cause performance problems and/or
engine damage which may not be covered under
warranty.
• Do not use gasoline containing methanol.
• Do not store fuel either in the fuel tank or fuel
containers over the winter unless a fuel stabilizer
is used.
• Do not add oil to gasoline.
g035134

DANGER
WARNING
In certain conditions, fuel is extremely
flammable and highly explosive. A fire or
explosion from fuel can burn you and others
and can damage property.
• Fill the fuel tank outdoors, in an open area,
when the engine is cold. Wipe up any
gasoline that spills.
• Never fill the fuel tank inside an enclosed
trailer.
• Do not fill the fuel tank completely full.
Add fuel to the fuel tank until the level is 6
to 13 mm (1/4 to 1/2 inch) below the bottom
of the filler neck. This empty space in the
tank allows fuel to expand.
• Never smoke when handling fuel and stay
away from an open flame or where fuel
fumes may be ignited by a spark.
• Store fuel in an approved container and
keep it out of the reach of children. Never
buy more than a 30-day supply of fuel.
• Do not operate without entire exhaust
system in place and in proper working
condition.
Fuel is harmful or fatal if swallowed.
Long-term exposure to vapors can cause
serious injury and illness.
• Avoid prolonged breathing of vapors.
• Keep your face away from nozzle and fuel
tank or conditioner bottle opening.
• Avoid contact with skin; wash off spills
with soap and water.
Using Stabilizer/Conditioner
Use a fuel stabilizer/conditioner in the machine to
provide the following benefits:
• Keeps fuel fresh during storage of 90 days or less.
For longer storage drain the fuel tank.
• Cleans the engine while it runs
• Eliminates gum-like varnish buildup in the fuel
system, which causes hard starting
Important: Do not use fuel additives
containing methanol or ethanol.
Add the correct amount of fuel stabilizer/conditioner
to the fuel.
Note: A fuel stabilizer/conditioner is most
effective when mixed with fresh fuel. To minimize
the chance of varnish deposits in the fuel system,
use fuel stabilizer at all times.
DANGER
In certain conditions during fueling, static
electricity can be released, causing a spark
that can ignite the gasoline vapors. A fire or
explosion from fuel can burn you and others
and can damage property.
• Always place fuel containers on the ground
away from your vehicle before filling.
• Do not fill fuel containers inside a vehicle
or on a truck or trailer bed, because interior
carpets or plastic truck bed liners may
insulate the container and slow the loss of
any static charge.
• When practical, remove equipment from
the truck or trailer and refuel the equipment
with its wheels on the ground.
• If this is not possible, then refuel such
equipment on a truck or trailer from a
portable container, rather than from a
fuel-dispenser nozzle.
• If you must use a fuel-dispenser nozzle,
keep the nozzle in contact with the rim of
the fuel tank or container opening at all
times until fueling is complete.

the machine after each use before the dirt hardens.
Remove dirt and grime from the external parts of the
entire machine, especially the engine. Clean dirt and
concrete materials from the outside of the engine.
Ensure that the fuel cap and the oil-fill cap/dipstick are
secure to avoid getting water in the engine.
Use care when using a high-pressure sprayer
because it can damage safety decals, instruction
signs, and the engine.
Important: Lubricate the trunnions after cleaning;
refer to Lubricating the Bearings and Seals (page
32).

Notes:
California Proposition 65 Warning Information
What is this warning?
You may see a product for sale that has a warning label like the following:
WARNING: Cancer and Reproductive Harm—www.p65Warnings.ca.gov.
What is Prop 65?
Prop 65 applies to any company operating in California, selling products in California, or manufacturing products that may be sold in or brought into
California. It mandates that the Governor of California maintain and publish a list of chemicals known to cause cancer, birth defects, and/or other
reproductive harm. The list, which is updated annually, includes hundreds of chemicals found in many everyday items. The purpose of Prop 65 is to
inform the public about exposure to these chemicals.
Prop 65 does not ban the sale of products containing these chemicals but instead requires warnings on any product, product packaging, or literature with
the product. Moreover, a Prop 65 warning does not mean that a product is in violation of any product safety standards or requirements. In fact, the
California government has clarified that a Prop 65 warning “is not the same as a regulatory decision that a product is ‘safe’ or ‘unsafe.’” Many of these
chemicals have been used in everyday products for years without documented harm. For more information, go to https://oag.ca.gov/prop65/faqs-view-all.
A Prop 65 warning means that a company has either (1) evaluated the exposure and has concluded that it exceeds the “no significant risk level”; or (2)
has chosen to provide a warning based on its understanding about the presence of a listed chemical without attempting to evaluate the exposure.
Does this law apply everywhere?
Prop 65 warnings are required under California law only. These warnings are seen throughout California in a wide range of settings, including but not
limited to restaurants, grocery stores, hotels, schools, and hospitals, and on a wide variety of products Additionally, some online and mail order
retailers provide Prop 65 warnings on their websites or in catalogs.
How do the California warnings compare to federal limits?
Prop 65 standards are often more stringent than federal and international standards. There are various substances that require a Prop 65 warning
at levels that are far lower than federal action limits. For example, the Prop 65 standard for warnings for lead is 0.5 μg/day, which is well below
the federal and international standards.
Why don’t all similar products carry the warning?
•
•
Products sold in California require Prop 65 labelling while similar products sold elsewhere do not.
•
•
The enforcement of Prop 65 is inconsistent.
A company involved in a Prop 65 lawsuit reaching a settlement may be required to use Prop 65 warnings for its products, but other companies
making similar products may have no such requirement.
Companies may elect not to provide warnings because they conclude that they are not required to do so under Prop 65; a lack of warnings for a
product does not mean that the product is free of listed chemicals at similar levels.
Why does Toro include this warning?
Toro has chosen to provide consumer with as much information as possible so that they can make informed decisions about the products they buy and
use. Toro provides warnings in certain cases based on its knowledge of the presence of one or more listed chemicals without evaluating the level of
exposure, as not all the listed chemical provide exposure limit requirements. While the exposure from Toro products may be negligible or well within the
“no significant risk” range, out of an abundance of caution, Toro has elected to provide the Prop 65 warnings. Moreover, if Toro does not provide these
warnings, it could be sued by the State of California or by private parties seeking to enforce Prop 65 and subject to substantial penalties.
