1. Safety rules for USA

These instructions are for your safety. Read them carefully.

Safe operation practices for ride-on mowers

IMPORTANT!
This cutting machine is capable of amputating hands and feet and throwing objects. Failure to

observe the following safety instructions could result in serious injury or death.

I. General operation

1. Read, understand and follow all instructions in
the manual and on the machine before

starting.

2. Only allow responsible adults, who are familiar
with the instructions, to operate the machine.

3. Clear the area of objects such as rocks, toys,
wire, etc., which could be picked up and

thrown by the blade.

4. Be sure the area is clear of other people
before mowing. Stop the machine if anyone

enters the area.

5. Never carry passengers.

6. Do not mow in reverse unless absolutely
necessary. Always look down and behind

before and while backing.

7. 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.

8. Slow down before turning.

9. Never leave a running machine unattended.
Always turn off blades, set parking brake, stop

engine and remove keys before dismounting.

10. Turn off blades when not mowing.

11. Stop engine before removing grass catcher or
unclogging chute.

12. Mow only in daylight or good artificial light.

13. Do not operate the machine while under the
influence of alcohol or drugs.

14. Watch for traffic when operating near or
crossing roadways.

15. Use extra care when loading or unloading the
machine into a trailer or truck.

II. Slope operation

Slopes are a major factor related to loss-of-control
and tip-over accidents, which can result in severe
injury or death. All slopes require extra caution. If
you cannot back up the slope or if you feel uneasy
on it, do not mow it.

DO

Mow up and down slopes, not across.
Remove obstacles such as rocks, tree limbs,

etc.
Watch for holes, ruts or bumps. Uneven

terrain could overturn the machine. Taft grass

can hide obstacles.

Use slow speed. Choose a low gear so that
you wilt not have to stop or shift while on the

slope.
Follow the manufacturer's recommendations

for wheel weights or counterweights to improve
stability.

Use extra care with grass catchers or other
attachments. These can change the stability of
the machine.

Keep all movement on the slopes slowand
gradual Do not make sudden changes in

speed or direction.
Avoid starting or stopping on a slope. If tires

lose traction, disengage the blades and
proceed slowly straight down the slope.

DO NOT

Do not turn on slopes unless necessary and

then, turn slowly and gradually downhill, if
possible.

Do not mow near drop-offs, ditches or
embandments. The mower could suddenly turn

over if a wheel is 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 try to stabilize the machine by putting
your foot on the ground.

Do not use grass catcher on steep slopes.

III. Children

Tragic accidents can occur if the operator is not
alert to the presence of children. Children are often

attracted to the machine and the mowing activity.

Never assume that children wilt remain where you

last saw them.

1. Keep children out of the mowing area and
under the watchful care of another responsible
adult.

2. Be alert and turn machine off if children enter
the area.

3. Before and when backing, look behind and
down for small children.

4. Never carry children. They may fall off and be
seriously injured or interfere with safe machine
operation.

5. Never allow children to operate the machine.

6. Use extra care when approaching blind
corners, shrubs, trees or other objects that may

obscure vision.

2 - English

1. Safety rules for USA

IV. Service

1. Use extra care in handling gasoline and other
fuels. They are flammable and vapours are

explosive.
a) Use only an approved container.
b) Never remove gas cap or add fuel with the

engine running. Allow engine to cool before

refuelling. Do not smoke.

c) Never refuel the machine indoors.
d) Never store the machine or fuel container

inside where there is an open flame, such as
in a water heater.

2. Never run a machine inside a closed area.

3. Keep nuts and bolts, especially blade
attachment bolts, tight and keep equipment in

good condition.

4. Never tamper with safety devices. Check their
proper operation regularly.

5. Keep machine free of grass, leaves or other
debris build-up. Clean up oil or fuel spillage.
Allow machine to cool before storing.

6. Stop and inspect the equipment if you strike an
object. Repair, if necessary, before restarting.

7. Never make adjustments or repairs with the
engine running.

8. Grass catcher components are subject to wear,
damage and deterioration, which could expose
moving parts or allow objects to be thrown.
Frequently check components and replace with
manufacturer's recommended parts, when
necessary.

9. Mower blades are sharp and can cut. Wrap the
blade(s) or wear gloves and use extra caution
when servicing them.

10. Check brake operation frequently. Adjust and
service as required.

Travel and transport on public roads
Check the relevant road traffic regulations before

driving the machine on a public road. If transporting
the machine on another vehicle always use

approved securing devices and make sure that the

machine is securely held.

Towing

If your machine has a hydrostatic transmission you

should only tow it very short distances at low speed

if absolutely necessary, otherwise the transmission
may be damaged.

Intended use

This machine is designed solely for cutting grass
on conventional lawns and other cleared and

leveled ground without obstacles, as rocks, stumps

etc., and, in conjunction with accessories supplied

by the manufacturer even for other special tasks

for which instructions are delivered with the
accessory. Use in any other way is considered as

contrary to the intended use. Compliance with and
strict adherence to the conditions of operation,

service and repair as specified by the manufacturer
also constitute essential elements of the intended

use.

This machine should be operated, serviced and

repaired only by persons who are familiar with its
particular characteristics and who are acquainted

with the relevant safety procedures.
Accident prevention regulations, all other generally

recognised regulations on safety and occupational
medicine, and all road traffic regulations must be

observed at all times.
Any arbitrary modifications carried out to this

machine may relieve the manufacturer of liability for

any resulting damage or injury.

Safe operation practices for Ride-On Mowers

Before starting cutting operations, train different

driving operations on an open ground without

people nearby until you feel familiar with handling

the equipment. This is particularly important if you

have no or little prior experience of driving a

vehicle.

Data indicates that operators, age 60 years and

above, are involved in a large percentage of riding

mower-related injuries. These operators should

evaluate their ability to operate the riding mower
safely in order to protect themselves and others

from serious injury.

Never carry children, even with the blades off. They
may fall off and be seriously injured or interfere with

safe machine operation.

Danger, keep hands and.fOet away

SAFETY INSTRUCTIONS

Driving on slopes

Driving on slopes is one of the operations where
the risk of the driver losing control of the machine

or of it overturning is the greatest; this can result in
serious injury or death. All slopes demand extra

care. If you cannot reverse up a slope or if you feet
unsure, do not mow it.

Proceed as follows:

• Remove obstacles such as stones, branches,

etc.

• Mow upwards and downwards, not sideways.

• Do not use the machine on ground that slopes
more than 15°.

• Avoid starting or stopping on a slope. If the tyres
start to slip, stop the blades and drive slowly
down the slope.

• Always drive smoothly and slowly on slopes.

• Do not make any sudden changes in speed or
direction.

Mow upwards and downwards on slopes, not sideways.

6003=004

• Avoid unnecessary turns on slopes, if
necessary, turn slowly and gradually downwards
if possible.

Watch out for and avoid driving over furrows,
holes and bumps. It is easier for the machine to
overturn on uneven ground. Tall grass can hide

obstacles.

• Drive slowly. Do not turn the wheel sharply. The
machine engine-brakes better in low gear.

• Take extra care if any attachments are fitted that
can change the stability of the machine.

Do not mow too close to edges, ditches or
banks. The machine can suddenly overturn if
one wheel comes over the edge of a steep
slope or a ditch, or if an edge gives way.

• Do not mow wet grass. It is slippery, and tyres
can lose their grip so that the machine skids.

• Do not try to stabilize the machine by putting
your foot on the ground.

• When cleaning the chassis the machine must
never be driven close to an edge or ditch.

• Foltowthe manufacturer's recommendations
regarding wheel weights or counterbalance

weights to increase stability.

Be especially care[ul when driving on slopes.
