and damage to the product. Although Toro designs,

The Toro warning system in this manual identifies
potential hazards and has special safety messages that
help you and others avoid personal injury, even death.
DANGER, WARNING and CAUTION are signal
words used to identify the level of hazard. However,
regardless of the hazard, be extremely careful.
DANGER signals an extreme hazard that will cause
serious injury or death if the recommended
precautions are not followed.
WARNING signals a hazard that may cause serious
injury or death if the recommended precautions are
not followed.
CAUTION signals a hazard that may cause minor or
moderate injury if the recommended precautions are
not followed.
Two other words are also used to highlight
information. “Important” calls attention to special
mechanical information and “Note” emphasizes
general information worthy of special attention.
The left and right side of the machine is determined
by standing behind the handle in the normal
operator’s position.

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 lawnmower. 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
responsible for accidents or hazards occurring to
other people or their property.
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 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 refuelling.
•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 area 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.
5. Before using, always visually inspect to see that
the blades, blade bolts and cutter assembly are
not worn or damaged. Replace worn or damaged
blades and bolts in sets to preserve balance.
6. On multi–bladed machines, take care as rotating
one blade can cause other blades to rotate.
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. Avoid operating the equipment in wet grass,
where feasible.
4. Always be sure of your footing on slopes.
5. Walk, never run.
6. For wheeled rotary machines, mow across the
face of slopes, never up and down.
7. Exercise extreme caution when changing
direction on slopes.
8. Do not mow excessively steep slopes.
9. Use extreme caution when reversing or pulling
the lawnmower towards you.

Safety
GB–3
10. Stop the blade(s) if the lawnmower has to be
tilted for transportation when crossing surfaces
other than grass, and when transporting the
lawnmower to and from the area to be mowed.
11. Never operate the lawnmower with defective
guards or shields, or without safety devices for
example deflectors and/or grass catchers in
place.
12. Do not change the engine governor settings or
overspeed the engine.
13. Disengage all blade and drive clutches before
starting the engine.
14. Start the engine or switch on the motor carefully
according to instructions and with feet well away
from the blade(s).
15. Do not tilt the lawnmower when starting the
engine or switching on the motor, except if the
lawnmower has to be tilted for starting. In this
case, do not tilt it more than absolutely necessary
and lift only the part which is away from the
operator.
16. Do not start the engine when standing in front of
the discharge chute.
17. Do not put hands or feet near or under rotating
parts. Keep clear of the discharge opening at all
times.
18. Never pick up or carry a lawnmower while the
engine is running.
19. Stop the engine and disconnect the spark plug
wire.
•before clearing blockages or unclogging
chute;
•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
lawnmower;
•if lawnmower starts to vibrate abnormally
(check immediately).
20. Stop the engine
•whenever you leave the lawnmower;
•before refuelling.
21. Reduce the throttle setting during engine shut
down and, if the engine is provided with a
shut-off 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.
6. Replace worn or damaged parts for safety.
7. If the fuel tank has to be drained, this should be
done outdoors.
