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.
Follow the manufacturer’s recommendations for
wheel weights or counterweights to improve
stability.
Use extra care with 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.
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.
Avoid starting or stopping on a slope. If tires
lose traction, disengage the blades and
proceed 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.
DO NOT
5. Never carry passengers.
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.
6. Do not mow in reverse unless absolutely
necessary. Always look down and behind
before and while backing.
7. Slow down before turning.
8. Never leave a running machine unattended.
Always turn off blades, set parking brake, stop
engine and remove keys before dismounting.
9. Turn off blades when not mowing.
10. Mow only in daylight or good artificial light.
11. Do not operate the machine while under the
influence of alcohol or drugs.
III. Children
11. Watch for traffic when operating near or
crossing roadways.
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.
1. Keep children out of the mowing area and
under the watchful care of another responsible
adult.
13. Use extra care when loading or unloading the
machine into a trailer or truck.
14. Always wear eye protection when operating
machine.
II. Slope operation
2. Be alert and turn machine off if children enter
the area.
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.
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.
Watch for holes, ruts or bumps. Uneven terrain
could overturn the machine. Tall grass can
hide obstacles.
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.
Use slow speed. Choose a low gear so that
you will not have to stop or shift while on the
slope.

proper operation regularly.
6. Never fill containers inside a vehicle or on a
truck or trailer bed with a plastic liner. Allways
place containers on the groundaway from your
vehicle before filling
5. Keep machine free of grass, leaves or other
debris build-up. Clean up oil or fuel spillage.
Allow machine to cool before storing.
7. Remove gas-powered equipment from the truck
or trailer and refuel it on the ground. If this is not
possible, then refuel such equipment with a
portable container, rather than from a gasoline
dispenser nozzle.
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. Mower blades are sharp and can cut. Wrap the
blade(s) or wear gloves and use extra caution
when servicing them.
8. Keep the nozzle in contact with the rim of the
fuel tank or container opening at all times until
the fueling is complete. Do not use a nozzle
lock-open device.
9. Check brake operation frequently. Adjust and
service as required.

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.
2. Follow the manufacturer´s recommendation for
weight limits for towed equipment and towing
on slopes.
3. Never allowe children or others in or on towed
equipment.
4. On slopes, the weight of the towed equipment
may cause loss of traction and loss of control.
5. Travel slowly and allow extradistance to stop.
Never carry children, even with the blades off. They
may fall off and be seriously injured or interfere with
safe machine operation.
