SAFETY INFORMATION
The safety of this machine relies on it being
operated within the conditionsthat
explained in this manual. Please read the
manual carefully before operating. Make
sure the operator is thoroughly familiar
with the safety rules.
Trainings
Regard the machine as a piece of power
equipment, so any person who operates the
machine MUST be trained and capable of
the safe operation of the equipment and
controls.
Know your controls and how to stop the
machine, engine and mower deck in an
emergency.
To avoid accident or injury, DO NOT allow
anyone to operate this machine without
reading the instruction.
Never allow young children,or unqualified
individuals to operate the equipment.
Keep young children and pets,away from
the zone of operation to avoid accidents or
hazards to other people or their property.
Preparation
While mowing,always wear tight and belted
clothing. Wear protected footwear. Never
operate the machine in barefeet, open toed
footwear .
Walk around machine and visually inspect
for damaged, loose, or missing components.
DO NOT operate unless all components are
properly installed, adjusted and in good
working condition.
Make sure all safety switches function
properly. See Operation section for details.
Make sure all safety shielding is in good
condition and properly installed.
Check brake action before you operate.
Adjust or check brakes as required.
Make sure all safety decals are installed and
in good condition.
Remove accumulated debris from machine
to avoid fire hazard.
Thoroughly inspect area to be cut and
remove stones, branches, wires and
accumulateddebris that might be thrown
causing personal injury or damage.
Evaluate the terrain to determine what
accessories and attachments are needed to
properly and safely perform the job.
Never permit any person, besides the
operator, to ride or operate the mower at any
time.
Operate only in daylight or good artificial
light.
Fuel Handling Safety
In certain conditions, gasoline is extremely
flammable and highly explosive. A fire or
explosion from gasoline can burn you and
others and can damage property.
Fill the fuel tank outdoors, in an open area,
when the engine is cold. Wipe up any
spillgasoline.
DO NOT fill the fuel tank completely full.
Add gasoline to the fuel tank until the level
of the filler neck. This empty space in the
tank allows gasoline to expand.
Never smoke when handling gasoline, and
keep away from open flames or where
gasoline fumes may be ignited by a spark.
Store gasoline in an approved container and
keep it out of the reach of children. Never
buy more than a 30-day supply of gasoline.
Always place gasoline containers on the
ground away from your vehicle before
filling.
DO NOT fill gasoline 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 gas-powered
equipment from the truck or trailer and
CAUTION

- 6 -
refuel the equipment when its wheels are 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
gasoline dispenser nozzle.
If a gasoline 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.
Never use cellular phones or other portable
electronic devices when handling fuel.
Operational Safety
Read “Operation” section of this manual
before attempting to operate this machine.
DO NOT operate without ROPS (Roll Over
Protection System) deployed.
Fenders serve as shields. DO NOT operate
without them.
DO NOT drive machine without mower
deck installed. The proper stability of the
machine depends on the weight of the
mower deck.
Keep bystanders away from equipment
whist it is in operation.
Keep children and pets a safe distance.
Never directly discharge towards a person.
Start engine from operator’s seat after
disengaging PTO and placing steering

forward to backward or backward to
forward position rapidly. The sudden
direction change may cause loss of control.
DO NOT operate on steep slopes greater
than 15 degrees.

suddenly on slopes.
Use extra care and maintain minimum
ground speed when traveling or operating
