IMPORTANT!  
This cutting machine is capable of amputating hands and feet and throwing objects. Failure to ob-  
serve the following safety instructions could result in serious injury or death.  
Use slow speed. Choose a low gear so that  
you will not have to stop or shift while on the  
I. General operation

with the instructions, to operate the machine.  
Use extra care with grass catchers or other  
3. Clear the area of objects such as rocks, toys,  
wire, etc., which could be picked up and  
thrown by the blade.  
attachments. These can change the stability of  
the machine.  
Keep all movement on the slopes slow and  
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 pro-  
ceed slowly straight down the slope.  
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.  
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.  
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.  
Do not use grass catcher on steep slopes.  
12. Mow only in daylight or good artificial light.  
III. Children  
13. Do not operate the machine while under the  
influence of alcohol or drugs.  
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 will remain where you  
last saw them.  
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.  
1. Keep children out of the mowing area and  
under the watchful care of another responsible  
adult.  
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.  
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.  
DO  
Mow up and down slopes, not across.  
Remove obstacles such as rocks, tree limbs,  
etc.  
5. Never allow children to operate the machine.  
Watch for holes, ruts or bumps. Uneven terrain  
could overturn the machine. Tall grass can  
hide obstacles.  
6. Use extra care when approaching blind cor-  
ners, shrubs, trees or other objects that may  
obscure vision.

SAFETY INSTRUCTIONS  
Travel and transport on public roads  
IV. Service  
Check the relevant road traffic regulations before  
driving the machine on a public road. If transporting  
the machine on another vehicle always use ap-  
proved securing devices and make sure that the  
machine is securely held.  
1. Use extra care in handling gasoline and other  
fuels. They are flammable and vapours are  
explosive.  
a) Use only an approved container.  
Towing  
b) Never remove gas cap or add fuel with the  
engine running. Allow engine to cool before  
refuelling. Do not smoke.  
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.  
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.  
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 acces-  
sory. Use in any other way is considered as con-  
trary 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.  
2. Never run a machine inside a closed area.  
3. Keep nuts and bolts, especially blade attach-  
ment 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.  
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 vehi-  
cle.  
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.  
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 feet away

SAFETY INSTRUCTIONS  
Watch out for traffic when working close to a  
road, or crossing one.  
Be careful when rounding a fixed object so that  
the blades do not hit it. Never drive intentionally  
over a foreign object.  
The machine is heavy and can cause very  
severe crush injuries. Be extra careful when  
loading it on a trailer or truck.  
Be careful when pulling a load or using heavy  
equipment.  
a. Only use approved tow hooks.  
b. Limit the load to what you can manage safely.  
c. Do not make sharp turns. Be careful when  
reversing.  
d. Use counterweights or wheel weights when  
indicated in the instructions.  
Driving on slopes  
Driving on slopes is one of the situations where  
there is the most serious risk that the driver can  
loose control or that the machine tips over, which  
can cause severe injuries or be fatal. All slopes  
require extra care. If you cannot reverse up the  
slope or if you feel uncertain avoid cutting it.

Remove obstacles such as stones and branches  
etc.  
Cut upwards and downwards, not sideways.  
Look out for and avoid driving over furrows,  
holes or mounds. On uneven surfaces it is  
easier for the machine to tip over. High grass  
can conceal obstacles.  
Be extra careful when driving on slopes.  
Drive slowly. Select a low gear to avoid having  
to stop and changing gear. It is also easier to  
use the gear to brake in a low gear.  
Follow the manufacturer’s recommendations on  
wheelweights or counterweights to increase  
stability.  
Be extra careful with the grass collector or other  
equipment which can alter the stability of the  
machine.  
Always drive smoothly and slowly on slopes.  
Avoid sudden changes of speed or direction.  
Avoid starting or stopping on a slope. If the tyres  
begin to skid switch of the blades and drive  
slowly down the slope.  
Cut slopes upwards and downwards, not sideways.  
Avoid unnecessary turns on slopes, and if  
turning is necessary turn slowly and gradually,  
downwards if possible.

SAFETY INSTRUCTIONS  
Do not cut close to edges, ditches or banks. The  
machine can suddenly tip over if a wheel goes  
over the edge of a drop or a ditch, or if a bank  
gives way.  
Do not cut wet grass. It is slippery and the tyres  
can loose their grip so that the machine slides.  
Do not try to stabilise the machine by placing one  
foot on the ground.  
Always keep the rider mower away from edges or  
ditches when cleaning the chassis.  
Children  
Tragic accidents can occur if the driver does not pay  
attention to children in the vicinity. Children are often  
attracted to the machine and the work of mowing.  
Never assume that children stay where you last saw  
them.  
Keep children away from the mowing area.  
Keep children away from the mowing area and  
under the supervision of another adult.  
Be on your guard and switch off the machine if  
children come into the work area.  
Before and during reversing look behind and  
down for small children.  
Never allow children to ride on the machine.  
They can fall off and become seriously injured or  
obstruct a risky manoeuvre of the machine.
