This manual identifies potential hazards and has special
safety messages that help you and others avoid personal
injury and 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 you do not follow the recommended
precautions.
Warning signals a hazard that may cause serious injury or
death if you do not follow the recommended precautions.
Caution signals a hazard that may cause minor or moderate
injury if you do not follow the recommended precautions.
This manual uses 2 other words to highlight information.
Important calls attention to special mechanical
information and Note: emphasizes general information
worthy of special attention.
Safety
• Do not carry passengers.
• 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;
– 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 effect of ground
conditions, especially slopes;
• incorrect hitching and load distribution.
Preparation
• While mowing, always wear substantial footwear and
long trousers. Do not operate the equipment when
barefoot or wearing open sandals.
Safe Operation Practices for
Riding Rotary Lawn Mowers
Read and understand the contents of this manual before
operating the tractor.
This is the safety alert symbol. It is used to alert you
to potential personal injury hazards. Obey all safety
messages that follow this symbol to avoid possible
injury or death.
The following instructions are from the CEN standard EN
836:1997.
This product is capable of amputating hands and feet and of
throwing objects. Always follow all safety instructions to
avoid serious injury or death.
Training
• Read the instructions carefully. Be familiar with the
controls and the proper use of the equipment.
• Never allow children or people unfamiliar with these
instructions to use the lawnmower. Local regulations
can restrict the age of the operator.
• Never mow while people, especially children, or pets
are nearby.
• Thoroughly inspect the area where the equipment is to
be used and remove all objects which may be thrown by
the machine.
• Warning—Fuel 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 fuel while the engine
is running or when the engine is hot.
– If fuel 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 fuel vapors have dissipated.
– Replace all fuel tanks and container caps securely.
• Replace faulty silencers.
• 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.

• On multi-bladed machines, take care as rotating one
blade can cause other blades to rotate.
Operation
• Do not operate the engine in a confined space where
dangerous carbon monoxide fumes can collect.
• Mow only in daylight or in good artificial light.
• Before attempting to start the engine, disengage all
blade attachment clutches and shift into neutral.
• Do not use on slopes of more than
–5 when mowing on side hills;
–10 when mowing uphill;
–15 when mowing downhill.
• Remember there is no such thing as a safe slope. Travel
on grass slopes requires particular care. To guard
against overturning:
– do not stop or start suddenly when going up or
downhill;
– engage clutch slowly, always keep machine in gear,
especially when travelling downhill;
– machine speeds should be kept low on slopes and
during tight turns;
– stay alert for humps and hollows and other hidden
hazards;
– never mow across the face of the slope, unless the
lawnmower is designed for this purpose.
• 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.
• Watch out for traffic when crossing or near roadways.
• Stop the blades rotating before crossing surfaces other
than grass.
• When using any attachments, never direct discharge of
material toward bystanders nor allow anyone near the
machine while in operation.
• Never operate the machine with damaged guards or
without safety protective devices in place.
• Do not change the engine governor settings or
overspeed the engine. Operating the engine at excessive
speed can increase the hazard of personal injury.
• Before leaving the operator’s position:
– disengage the power take-off and lower the
attachments;
– change into neutral and set the parking brake;
– stop the engine and remove the key.
• Disengage drive to attachments, stop the engine, and
disconnect the spark plug wire(s) or remove the ignition
key
– 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 equipment;
– if the machine starts to vibrate abnormally (check
immediately).
• Disengage drive to attachments when transporting or
not in use.
• Stop the engine and disengage drive to attachment
– before refuelling;
– before removing the grass catcher;
– before making height adjustment unless adjustment
can be made from the operator’s position.
• Reduce the throttle setting during engine run-out and, if
the engine is provided with a shut-off valve, turn the
fuel off at the conclusion of mowing.
Maintenance and Storage
• Keep all nuts, bolts and screws tight to be sure the
equipment is in safe working condition.
• Never store the equipment with fuel in the tank inside a
building where fumes can reach an open flame or spark.
• Allow the engine to cool before storing in any
enclosure.
• To reduce the fire hazard, keep the engine, silencer,
battery compartment and fuel storage area free of grass,
leaves, or excessive grease.
• Check the grass catcher frequently for wear or
deterioration.
• Replace worn or damaged parts for safety.
• If the fuel tank has to be drained, this should be done
outdoors.
• On multi-bladed machines, take care as rotating one
blade can cause other blades to rotate.
• When machine is to be parked, stored or left
unattended, lower the cutting means unless a positive
mechanical lock is used.

Gasoline and Oil
Recommended Gasoline
Use unleaded regular gasoline suitable for automotive use
(85 pump octane minimum). You may use leaded regular
gasoline 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.

6. Reverse
2. To push the tractor, pull

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 in. (6 to 13 mm) below the bottom of the
filler neck. This empty space in the tank allows
the gasoline to expand.
• Never smoke when handling gasoline, and stay
away from an open flame or where a spark may
ignite the gasoline fumes.
• 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, refuel such equipment on
a truck or trailer from a portable container, not
from a gasoline dispenser nozzle.
• If you must use a gasoline dispenser, keep the
nozzle in contact with the rim of the fuel tank or
container opening at all times until fueling is
complete.
