Toro Mower Safety
The following list contains safety information specific
to Toro products and other safety information you
must know.
This product is capable of amputating hands and feet and
throwing objects. Always follow all safety instructions to
avoid serious injury or death.
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.
4
• 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.
• 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.
• Keep hands, feet, hair and loose clothing away from
attachment discharge area, underside of mower and any
moving parts while engine is running.
• 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
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.
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 genuine replacement parts to ensure that
original standards are maintained.
• Check brake operation frequently. Adjust and service as
required.
• Use slow speed so that you will not have to stop while
on the slope.
• Use extra care with grass catchers or other attachments.
These can change the stability of the machine.
• 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.

Gasoline and Oil
Warning
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.
• Never fill the fuel tank inside an enclosed trailer.
• Do not fill the fuel tank completely full. Add
gasoline to the fuel tank until the level is 1/4 to
1/2 in. (6 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.
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 set the parking brake.
2. Clean around the fuel tank cap and remove the cap. Add
unleaded regular gasoline to both fuel tanks, 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.
Checking the Engine Oil Level
Before you start the engine and use the machine, check the
oil level in the engine crankcase; refer to Checking the
Engine Oil Level, page 27.
