Toro Mower Safety
The following list contains safety information
specific to Toro products or other safety information
that you must know that is not included in the ANSI
standards.
4
This product is capable of amputating hands and feet and
throwing objects. Always follow all safety instructions to
avoid serious injury or death.
• Use extra care with grass catchers or other
attachments. These can change the stability of the
machine.
This product is designed for cutting and recycling grass or,
when equipped with a grass bagger, for catching cut grass.
Any use for purposes other than these could prove
dangerous to user and bystanders.
General Operation
• Allow only responsible adults who are familiar with
the instructions to operate the machine.
• Be sure the area is clear of other people before
mowing. Stop the machine if anyone enters the area.
• Do not mow in reverse unless absolutely necessary.
Always look down and behind before and while
backing.
• Be aware of the mower discharge direction and do not
point it at anyone. Do not operate the mower without
either the entire grass catcher or the guard in place.
• Slow down before turning. Sharp turns on any terrain
may cause loss of control.
• Turn off blades when not mowing.
• Keep hands, feet, hair and loose clothing away from
attachment discharge area, underside of mower and
any moving parts while engine is running.
• Keep all movement on slopes slow and gradual. Do
not make sudden changes in speed or direction.
• Avoid starting or stopping on a slope. If tires lose
traction, disengage the blades.
• Check carefully for overhead clearances (i.e. branches,
doorways, electrical wires) before driving under any
objects and do not contact them.
• Mow slopes side–to–side.
DO NOT
• Do not mow slopes greater than 15 degrees.
• Avoid turning on slopes. If you must turn, turn slowly
and gradually downhill, if possible.
• Do not mow near drop-offs, ditches, or embankments.
The machine could suddenly turn over if a wheel goes
over the edge of a cliff or ditch, or if an edge caves in.
• Do not mow on wet grass. Reduced traction could
cause sliding.
• Do not use a grass catcher on steep slopes. Heavy
grass bags could cause loss of control, of the machine.
• Do not mow up and down slopes.
• Stop the engine before removing the grass catcher or
unclogging the chute.
• Mow only in daylight or good artificial light.
• Watch for traffic when operating near or crossing
roadways.
• Do not touch equipment or attachment parts which
may be hot from operation. Allow to cool before
attempting to maintain, adjust or service.
• Use only Toro-approved attachments. Warranty may
be voided if used with unapproved attachments.
Slope Operation
Slopes and ramps are a major factor related to
loss-of-control and accidents, which can result in severe
injury or death. All slopes and ramps require extra
caution. If you feel uneasy on a slope, do not mow it.
DO
• Remove obstacles such as rocks, tree limbs, etc. from
the mowing area. Watch for holes, ruts or bumps. Tall
grass can hide obstacles.
• Use slow speed so that you will not have to stop while
on the slope.
Service
• Never store the machine or fuel container inside where
there is an open flame, such as near a water heater or
furnace.
• Keep nuts and bolts tight, especially the blade
attachment bolts. Keep equipment in good condition.
• Never tamper with safety devices. Check safety
systems for proper operation before each use.
• Use only Toro genuine replacement parts to ensure that
original standards are maintained.
• Battery acid is poisonous and can cause burns. Avoid
contact with skin, eyes and clothing. Protect your face,
eyes and clothing when working with a battery.
• Battery gases can explode. Keep cigarettes, sparks and
flames away from battery.
• Hydraulic fluid escaping under pressure can penetrate
the skin and cause injury. Use cardboard or paper to
find hydraulic leaks. Never use your hands.

Gasoline and Oil
Recommended Gasoline
Use UNLEADED Regular Gasoline suitable for
automotive use (85 pump octane minimum). Leaded
regular gasoline may be used if unleaded regular is not
available.
Important Never use methanol, gasoline containing
methanol, or gasohol containing more than 10% ethanol
because the fuel system could be damaged. Do not mix oil
with gasoline.
Danger
In certain conditions, gasoline is extremely
flammable and highly explosive. A fire or
explosion from gasoline 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.
• 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.
• Always place gasoline containers on the ground
away from your vehicle before filling.
• Do not fill gasoline 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 gas–powered
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 gasoline
dispenser nozzle.
• If a gasoline dispenser nozzle must be used,
keep the nozzle in contact with the rim of the
fuel tank or container opening at all times until
fueling is complete.
Warning
Gasoline is harmful or fatal if swallowed.
Long–term exposure to vapors can cause serious
injury and illness.
• Avoid prolonged breathing of vapors.
• Keep face away from nozzle and gas tank or
conditioner opening.
• Keep gas away from eyes and skin.
Using Stabilizer/Conditioner
Use a fuel stabilizer/conditioner in the machine to provide
the following benefits:
• Keeps gasoline fresh during storage of 90 days or less.
For longer storage it is recommended that the fuel tank
be drained.
• 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 gas stabilizer/conditioner to the
gas.
Note: A fuel stabilizer/conditioner is most effective when
mixed with fresh gasoline. To minimize the chance of
varnish deposits in the fuel system, use fuel stabilizer at
all times.
Filling the Fuel Tank
1. Shut the engine off and chock or block tires.
2. Clean around the fuel tank cap and remove the cap.
Add unleaded regular gasoline to fuel tank, until the
level is 1/4 to 1/2 inch (6 mm to 13 mm) below the
bottom of the filler neck. This space in the tank allows
gasoline to expand. Do not fill the fuel tank
completely full.
3. Install fuel tank cap securely. Wipe up any gasoline
that may have spilled.
Check Engine Oil Level
Before you start the engine and use the machine, check
the oil level in the engine crankcase; refer to Checking Oil
Level, page 27.
