Safety
Safe Operation Practices
for Ride-on (riding) Rotary
Lawnmower Machines
This machine meets or exceeds European Standards in
effect at the time of production. However, improper
use or maintenance by the operator or owner can
result in injury. To reduce the potential for injury,
comply with these safety instructions and always pay
attention to the safety alert symbol, which means
CAUTION, WARNING, or DANGER -“personal
safety instruction.” Failure to comply with the
instruction may result in personal injury or death.
Safe Operating Practices
The following instructions are from the EN standard
EN 836:1997.
This product is capable of amputating hands and
feet and 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.
• Keep in mind that the operator or user is responsible
for accidents or hazards occurring to other people or
their property.
• 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;
– stay alert for humps and hollows and other
hidden hazards;
◊ incorrect hitching and load distribution.
• Use care when pulling loads.
– Use only approved drawbar hitch points.
– Limit loads to those you can safely control.
– Do not turn sharply. Use care when reversing.
• Watch out for traffic when crossing or near roadways.
Preparation
• While mowing, always wear substantial footwear and
long trousers. Do not operate the equipment when
barefoot or wearing open sandals.
• Thoroughly inspect the area where the equipment
is to be used and remove all objects which may be
thrown by the machine.
• 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.
• Warning-Fuel is highly flammable.
– Store fuel in containers specifically designed for
this purpose.
• Never operate the machine with damaged guards or
without safety protective devices in place.
– Refuel outdoors only and do not smoke while
refuelling.
• Do not change the engine governor settings or
overspeed the engine. Operating the engine at
excessive speed can increase the hazard of personal
injury.
– 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.
• 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.
– Replace all fuel tanks and container caps securely.
• Replace faulty silencers.
• Disengage drive to attachments, stop the engine,
and disconnect the spark plug wire(s) or remove the
ignition key
• 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.
– before clearing blockages or unclogging chute;
• On multi-bladed machines, take care as rotating one
blade can cause other blades to rotate.
– 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;
Operation
• Be alert, slow down and use caution when making
turns. Look behind and to the side before changing
directions.
– if the machine starts to vibrate abnormally (check
immediately).
• Do not operate the engine in a confined space where
dangerous carbon monoxide fumes can collect.
• Disengage drive to attachments when transporting
or not in use.
• Mow only in daylight or in good artificial light.
• Stop the engine and disengage drive to attachment
– before refuelling;
• Before attempting to start the engine, disengage all
blade attachment clutches and shift into neutral.
• Do not use on slopes of more than 15 degrees.
– before removing the grass catcher;
• Remember there is no such thing as a safe slope.
Travel on grass slopes requires particular care. To
guard against overturning:
– before making height adjustment unless
adjustment can be made from the operator’s
position.
– do not stop or start suddenly when going up or
downhill;
• 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.
– use low speeds on slopes and during tight turns;

• Do not mow slopes when grass is wet. Slippery
conditions reduce traction and could cause sliding
and loss of control.
Maintenance and Storage
• Keep all nuts, bolts and screws tight to be sure the
equipment is in safe working condition.
• Do not make sudden turns or rapid speed changes.
• Never store the equipment with fuel in the tank
inside a building where fumes can reach an open
flame or spark.
• Use a walk behind mower and/or a hand trimmer
near drop-offs, ditches, steep banks, or water.
• Allow the engine to cool before storing in any
enclosure.
• Reduce speed and use extreme caution on slopes.
• Remove or mark obstacles such as rocks, tree limbs,
etc. from mowing area. Tall grass can hide obstacles.
• To reduce the fire hazard, keep the engine, silencer,
battery compartment and fuel storage area free of
grass, leaves, or excessive grease.
• Watch for ditches, holes, rocks dips, and rises that
change the operating angle, as rough terrain could
overturn the machine.
• Check the grass catcher frequently for wear or
deterioration.
• Avoid sudden starts when mowing uphill because
the mower may tip backwards.
• Replace worn or damaged parts for safety.
• If the fuel tank has to be drained, this should be
done outdoors.
• Be aware that loss of traction may occur going
downhill. Weight transfer to the front wheels may
cause drive wheels to slip and cause loss of braking
and steering.
• When machine is to be parked, stored or left
unattended, lower the cutting means.
• Always avoid sudden starting or stopping on a
slope. If tyres lose traction, disengage the blades and
proceed slowly off the slope.

rollover:
use (87 pump octane minimum).
• Do not mow near drop-offs or near water.
• Do not mow slopes greater than 15 degrees.
• Reduce speed and use extreme caution on
slopes.
In certain conditions, petrol is extremely
flammable and highly explosive. A fire or
explosion from petrol can burn you and others
and can damage property.
• When mowing slopes, gradually work from
lower to higher areas on the incline.
• Fill the fuel tank outdoors, in an open area,
when the engine is cold. Wipe up any petrol
that spills.
• Avoid sudden turns or rapid speed changes.
• Turn up, into an incline when changing
directions on slopes. Turning down the
slope reduces traction.
• Never fill the fuel tank inside an enclosed
space.
• Attachments change the handling
characteristics of the machine. Use extra
caution when using attachments with the
machine.
• Do not fill the fuel tank completely full. Add
petrol to the fuel tank until the body of the
tank is full. Always leave the neck empty in
the fuel tank to allow the petrol to expand.
• Never smoke when handling petrol, and stay
away from an open flame or where petrol
fumes may be ignited by a spark.
• Store petrol in an approved container and
keep it out of the reach of children. Never
buy more than a 30-day supply of petrol.
• Do not operate without entire exhaust
system in place and in proper working
condition.

In certain conditions during fueling, static
electricity can be released causing a spark
which can ignite the petrol vapors. A fire or
explosion from petrol can burn you and others
and can damage property.
• Always place petrol containers on the
ground away from your vehicle before filling.
• Do not fill petrol 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 petrol-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 petrol
dispenser nozzle.
Filling the Fuel Tank
1. Shut the engine off and set the motion controls to
the park position. Raise the seat so the fuel tank is
visible while fueling.
• If a petrol 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.
2. Clean around the fuel tank cap and remove the cap.

expand. Do not fill the fuel tank completely full.
4. Install the fuel tank cap securely. Wipe up any petrol
that may have spilled.
Petrol 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 fuel tank or
conditioner opening.
• Keep fuel away from eyes and skin.
Using Stabilizer/Conditioner
Use a fuel stabilizer/conditioner in the machine to
provide the following benefits:
• Keeps petrol fresh during storage of 30 days or less.
For longer storage it is recommended that the fuel
tank be drained.

Long Grass
Operating Tips
If the grass is ever allowed to grow slightly longer than
normal, or if it contains a high degree of moisture, raise
the cutting height higher than usual and cut the grass at
this setting. Then cut the grass again using the lower,
normal setting.
Fast Throttle Setting
For best mowing and maximum air circulation, operate
the engine at the Fast position. Air is required to
thoroughly cut grass clippings, so do not set the
height-of-cut so low as to totally surround the cutter
deck by uncut grass. Always try to have one side of the
cutter deck free from uncut grass, which allows air to
be drawn into the cutter deck.
When Stopping
If the machine’s forward motion must be stopped while
mowing, a clump of grass clippings may drop onto your
lawn. To avoid this, move onto a previously cut area
with the blades engaged.
Cutting a Lawn for the First Time
Cut grass slightly longer than normal to ensure that the
cutting height of the cutter deck does not scalp any
uneven ground. However, the cutting height used in
the past is generally the best one to use. When cutting
grass longer than six inches tall, you may want to cut
the lawn twice to ensure an acceptable quality of cut.
Keep the Underside of the Cutter Deck
Clean
Clean clippings and dirt from the underside of the
cutter deck after each use. If grass and dirt build up
inside the cutter deck, cutting quality will eventually
become unsatisfactory.
Cut 1/3 of the Grass Blade
Blade Maintenance
It is best to cut only about 1/3 of the grass blade.
Cutting more than that is not recommended unless
grass is sparse, or it is late fall when grass grows more
slowly.
Maintain a sharp blade throughout the cutting season
because a sharp blade cuts cleanly without tearing or
shredding the grass blades. Tearing and shredding turns
grass brown at the edges, which slows growth and
increases the chance of disease. Check the cutter blades
daily for sharpness, and for any wear or damage. File
down any nicks and sharpen the blades as necessary. If
a blade is damaged or worn, replace it immediately with
a genuine Hayter replacement blade.
Mowing Direction
Alternate mowing direction to keep the grass standing
straight. This also helps disperse clippings which
enhances decomposition and fertilization.
Mow at Correct Intervals
Normally, mow every four days. But remember,
grass grows at different rates at different times. So
to maintain the same cutting height, which is a good
practice, mow more often in early spring. As the grass
growth rate slows in mid summer, mow less frequently.
If you cannot mow for an extended period, first mow
at a high cutting height; then mow again two days later
at a lower height setting.
Cutting Speed
To improve cut quality, use a slower ground speed.
Avoid Cutting Too Low
If the cutting width of the cutter deck is wider than the
cutter deck you previously used, raise the cutting height
to ensure that uneven turf is not cut too short.
