Safety
Training
1.Read the instructions carefully. Be familiar with
the controls and the proper use of the equipment.
2.Never allow children or people unfamiliar with
these instructions to use the lawn mower. Local
regulations may restrict the age of the operator.
3.Never mow while people, especially children, or
pets are nearby.
4.Keep in mind that the operator or user is responsi-
ble for accidents or hazards occurring to other
people or their property.
5.Do not carry passengers.
6.All drivers should seek and obtain professional
and practical instruction. Such instruction should
emphasize:
•the need for care and concentration when
working with ride-on machines;
is to be used and remove all objects which may
be thrown by the machine.
3.WARNING—Petrol is highly flammable.
•Store fuel in containers specifically designed
for this purpose.
•Refuel outdoors only and do not smoke
while refueling.
•Add fuel before starting the engine. Never
remove the cap of the fuel tank or add petrol
while the engine is running or when the
engine is hot.
•If petrol is spilled, do not attempt to start the
engine but move the machine away from the
are of spillage and avoid creating any source
of ignition until petrol vapors have dissipated.
•Replace all fuel tanks and container caps
securely.
4.Replace faulty silencers.
• control of a ride-on machine sliding on a
slope will not be regained by the application
of the brake. The main reasons for loss of
control are:
–insufficient wheel grip;
–being driven too fast;
–inadequate braking;
–the type of machine is unsuitable for its
task;
–lack of awareness of the effects of
ground conditions, especially slopes;
–incorrect hitching and load distribution.
Preparation
1.While mowing, always wear substantial footwear
and long trousers. Do not operate the equipment
when barefoot or wearing open sandals.
2.Thoroughly inspect the area where the equipment
Operation
1.Do not operate the engine in a confined space
where dangerous carbon monoxide fumes can collect.
2.Mow only in daylight or in good artificial light.
3.Before attempting to start the engine, disengage
all blade attachment clutches and shift into neutral.
4.Do not use on slopes of more than:
•Never mow side hills over 5°
•Never mow uphill over 10°
•Never mow downhill over 15°
5.Remember there is no such thing as a “safe”
slope. Travel on grass slopes requires particular
care. To guard against overturning:
3
Safety
•do not stop or start suddenly when going up
or downhill;
•engage the clutch slowly, and always keep
the machine in gear, especially when travailing downhill;
•machine speeds should be kept low on
slopes and during tight turns;
•stay alert for bumps and hollows and other
hidden hazards;
•never mow across the face of the slope,
unless the lawn mower is designed for this
purpose.
6. Use care when pulling loads or using heavy
equipment.
•Use only approved drawbar hitch points.
•Limit loads to those you can safely control.
•Do not turn sharply. Use care when reversing.
•Use counterweight(s) or wheel weights
when suggested in the instruction handbook.
• change into neutral and set the parking
brake;
• stop the engine and remove the key.
13. Disengage the drive to attachments when trans-
porting or not in use.
14. Stop the engine and disengage the drive to the
attachment
•before refueling;
•before removing the grass catcher;
•before making height adjustments unless the
adjustment can be made from the operator’s
position.
•before clearing blockages;
•before checking, cleaning or working on the
lawnmower;
•after striking a foreign object. Inspect the
lawnmower for damage and make repairs
before restarting and operating the equipment.
7. Watch out for traffic when crossing or near road-
ways.
8. Stop the blades rotating before crossing surfaces
other than grass.
9. When using any attachments, never direct dis-
charge of material toward bystanders nor allow
anyone near the machine while in operation .
10. Never operate the lawn mower with defective
guards, shields or without safety protective
devices in place.
11. Do not change the engine governor settings or
overspeed the engine. Operating the engine at
excessive speeds may increase the hazard of personal injury.
12. Before leaving the operator’s position:
• disengage the power take-off and lower the
attachments;
15. Reduce the throttle setting during engine runout
and, if the engine is provided with a shutoff
valve, turn the fuel off at the conclusion of mowing.
Maintenance and Storage
1.Keep all nuts, bolts and screws tight to be sure
the equipment is in safe working condition.
2.Never store the equipment with petrol in the tank
inside a building where fumes may reach an open
flame or spark.
3.Allow the engine to cool before storing in any
enclosure.
4.To reduce the fire hazard, keep the engine,
silencer, battery compartment and petrol storage
area free of grass, leaves, or excessive grease.
5.Check the grass catcher frequently for wear or
deterioration.
4
Safety
6. Replace worn or damaged parts for safety.
7. If the fuel tank has to be drained, this should be
done outdoors.
8. Be careful during adjustment of the machine to pre-
vent entrapment of the fingers between moving
blades and fixed parts of the machine.
9. On multi-bladed machines, take care as rotating
one blade can cause other blades to rotate.
10. When the machine is to be parked, stored or left
unattended, lower the cutting means unless a positive mechanical lock is used.

Before Operating
CAUTION
Before servicing or making adjustments to the
machine, stop the engine and remove the key
from the switch.
CHECK THE CRANKCASE OIL
The engine is shipped with oil in the crankcase; however, you must check the oil level before and after you first
start the engine.
1.Position the machine on a level surface.
2.Remove the dipstick and wipe it with a clean rag.
Push the dipstick down into the dipstick tube and
make sure it is seated fully. Pull out the dipstick
and check the oil level. If the level is low, add
enough oil to raise the level to the FULL mark on
the dipstick.
A.Above 0° C—Use SAE 30.
B.Below 0° C—Use SAE 5@-20 or 5W30.
IMPORTANT Check the oil level every 5 operating hours or daily. Change the oil after every 50
hours of operation.

the engine.
Before Operating
DANGER
Because gasoline is flammable, use caution when
storing or handling it.
•Do not fill the fuel tank while the engine is
running, hot or when the machine is in an
enclosed area. Vapors may build up and be
ignited by a spark or flame source many feet
away.
•DO NOT SMOKE while filling the fuel tank to
prevent the possibility of an explosion.
•Always fill the fuel tank outside and wipe up
any spilled gasoline, and fill the tank no higher
than to the bottom of the filter screen. DO
NOT OVERFILL.
•Store gasoline in a clean safety approved container and keep the cap on the container. Keep
gasoline in a cool, well-ventilated place; never
in an enclosed area such as a hot storage shed.
To assure volatility, do not buy more than a 30day supply of gasoline.
•Gasoline is a fuel for internal combustion
engines; do not use it for any other purpose.
•Store fuel in a clean, safety-approved container and keep the cap in place. Use
diesel fuel for the engine only; not for any
other purpose.
Gasoline Model:
THE TORO COMPANY STRONGLY RECOMMENDS THE USE OF FRESH, CLEAN, UNLEADED REGULAR GRADE GASOLINE IN TORO
GASOLINE POWERED PRODUCTS. UNLEADED
GASOLINE BURNS CLEANER, EXTENDS
ENGINE LIFE, AND PROMOTES GOOD STARTING BY REDUCING THE BUILD-UP OF COMBUSTION CHAMBER DEPOSITS. LEADED
GASOLINE CAN BE USED IF UNLEADED IS
NOT AVAILABLE.
•Since children like the smell of gasoline, keep
it out of their reach because the fumes are
explosive and dangerous to inhale.
1.Clean the area around the fuel tank cap and remove
the cap.
2.Fill the tank to about one inch below the top of the
tank, (bottom of filler neck). DO NOT OVERFILL. Then install the cap.
3.Wipe up any gasoline that may have spilled to pre-
vent a fire hazard.
