SAFETY INSTRUCTIONS
• Always wear gloves when handling the
blades.
• Never wear loose clothing that can get caught
in moving parts.
• Use ear protectors to avoid damage to
hearing.
• Stop the blade when crossing gravel
drives, walks, or roads.
• Shut the engine off and wait until the
blade comes to a complete stop before
removing grass catcher.
• Disengage the self-propelled mechanism
or drive clutch on mowers so equipped
before starting the engine.
• If the equipment should start to vibrate
abnormally, stop the engine and check
immediately for the cause. Vibration is
generally a warning of trouble.
• See manufacturer’s instructions for
proper operation and installation of
accessories. Use only accessories
approved by the manufacturer.
Operating on Slopes
Operating on slopes is one of the operations
where the risk is greatest that the operator
will lose control or the machine will tip over,
which can result in serious injury or death. All
slopes require extra caution. If you feel
unsure, do not mow the slope.
Do as follows
• Remove obstacles such as stones,
tree branches, etc.
• Watch out for and avoid running over
furrows, holes, and bumps. On uneven
terrain, the machine can tip more easily.
Long grass can hide obstacles.
• Mow across the face of slopes: never up
and down. Exercise extreme caution
when changing direction on slopes.
• Mow evenly and slowly.
• If the machine stops while going uphill,
back down slowly.
8019-002
Mow side to side, not up and down.
Do not
• Do not make sudden changes in speed
or direction.
English-
9
SAFETY INSTRUCTIONS
• Do not drive the mower on terrain that
slopes more than 10°.
• Do not mow near verges, ditches, or
banks. The operator could lose footing or
balance.
• Do not mow wet grass. Reduced footing
could cause slipping
• Do not turn on slopes unless necessary,
and then, turn slowly and gradually
downhill, if possible.
• Avoid starting or stopping on a slope. If
the tires begin to slip, shut down the
blades if so equipped or shut off the
engine and move slowly down the slope.
Children
• Serious accidents may occur if you fail to
be on guard for children in the vicinity of
the machine. Children are often attracted
to the machine and mowing work. Never
assume that children will stay where you
last saw them.
• Keep children away from the mowing
area and under close supervision by
another adult.
• Keep an eye out and shut off the
machine if children enter the work area.
• Before and during a reversing maneuver,
look backward and downward for
children.
• Never allow children to operate the
machine.
• Be particularly cautious near corners,
bushes, trees, or other objects that block
your view.
Maintenance
WARNING!
The engine must not be started when any protective plate for the mower deck’s drive
belt is removed.
• Stop the engine.
8019-003
Never allow children to operate the machine
• Never attempt to make wheel height
adjustments while the engine is running.
• Only store fuel in containers approved for
the purpose.
English-
10
SAFETY INSTRUCTIONS
• Keep the nozzle in contact with the rim of
the fuel tank or container opening at all
times until fueling is complete. Do not
use a nozzle lock-open device.
• Never fill containers inside a vehicle or
on a truck or trailer bed with a plastic
liner. Always place containers on the
ground away from your vehicle before
filling.
• 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.
• Never fill the fuel tank indoors.
• Fuel and fuel fumes are poisonous and
extremely flammable. Be especially
cautious when handling fuel, as
carelessness can result in personal
injury or fire.
• Never remove the fuel tank cap and
never fill the fuel tank while the engine is
running.
8019-004
Never fill the fuel tank indoors
Use protective glasses for
maintenance work.
• Allow the engine to cool before refueling.
Do not smoke. Do not fill fuel in the
vicinity of sparks or open flames.
• If leaks arise in the fuel system, the
engine must not be started until the
problem has been resolved.
• Store the machine and fuel in such a way
that there is no risk of leaking fuel or fuel
vapor leading to damages.
• Check the fuel level before each use and
leave space for the fuel to expand,
because the heat from the engine and
the sun may otherwise cause the fuel to
expand and overflow.
• Avoid overfilling. If you spill fuel on the
machine, wipe up the spill and wait until it
has evaporated before starting the
engine. If you have spilled fuel on your
clothing, change your clothing.
• 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
manufacture’s recommended parts, when
necessary.
WARNING!
The engine and the exhaust
system, become hot during
operation. Risk for burns if
touched.

regularly to be sure it works properly.
The machine must not be used with
defective or unmounted protective
plates, protective cowlings, safety
switches, or other protective devices.
• Do not change the settings of governors
and avoid running the engine with overly
high engine speeds. If you run the
engine too fast, you risk damaging the
machine components.
• Never use the mower indoors or in spaces
lacking proper ventilation. The exhaust fumes
contain carbon monoxide, an odorless,
poisonous, and lethal gas.
• Stop and inspect the equipment if you
run over or into anything. If necessary,
make repairs before starting.
8019-006
Clean the unit regularly
• The machine is tested and approved only
with the equipment originally provided or
recommended by the manufacturer.
• The blades are sharp and can cause
cuts and gashes. Wrap the blades or use
protective gloves when handling them.
• The mulch blades should only be used in
familiar areas when higher quality
mowing is desired.
• Reduce the risk of fire by removing
grass, leaves, and other debris that may
have accumulated on the machine. Allow
the machine to cool before putting it in
storage.
Transport
• The machine is heavy and can cause
serious crushing injuries. Be extra
cautious when it is loaded on or
unloaded from a vehicle or trailer.
• Use an approved trailer to transport the
mower. Fasten the machine with approved
fastening devices, such as straps, chains,
or ropes, when transporting.
