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
• 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.
• 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.
• 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
• 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.
• 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.
• 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.
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.
• 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.
• 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 in.
to 1/2 in. (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.
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.
Warning
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.

1. Position machine on a level surface and chock or block
tires.
2. Clean area around filler neck of hydraulic tank
(Fig. 9).
3. Remove cap from filler neck. Look inside to check if
there is fluid in the reservoir (Fig. 9).
4. If there is no fluid, add fluid to reservoir
approximately a 1/4 in. (6mm) below the top of baffle.
5. Run the machine 15 minutes to allow any air to purge
out of the system and warm fluid.
6. Recheck level while fluid is warm. Add fluid to raise
level to top of the baffle, if required.
Note: Fluid level should be to the top of the baffle when
fluid is warm (Fig. 9).
7. Install cap on filler neck.

Hydraulic fluid escaping under pressure can
penetrate skin and cause injury.
• If hydraulic fluid is injected into the skin it
must be surgically removed within a few hours
by a doctor familiar with this type of injury.
Gangrene may result if this is not done.
• Keep body and hands away from pin hole leaks
or nozzles that eject high pressure hydraulic
fluid.
• Use cardboard or paper to find hydraulic leaks.
• Relieve all pressure in the hydraulic system
before performing any work on the hydraulic
system.
• Make sure all hydraulic fluid hoses and lines
are in good condition and all hydraulic
connections and fittings are tight before
applying pressure to hydraulic system.
