or situations and will be followed by the word
DANGER, WARNING, or CAUTION.
DANGER: White lettering/Red
background.
Indicates failure to observe the safety
instructions will result in death or serious injury.
WARNING: Black letters on orange
background.
Indicates failure to observe safety instructions
could result in death or serious injury.
CAUTION: Black letters on yellow
background.
Indicates failure to observe the safety
instructions may result in death or serious

TRAINING
• Read the instructions carefully. Become
familiar with the safe operation of the
equipment, operator controls, and safety
signs.
• All operators need to be trained before
operating this unit.
• Never let children or untrained people
operate the equipment without proper
instruction.
• Keep everyone, especially children and
pets, away from the area of operation.
Remember that the operator or user is
responsible for accidents or hazards
occurring to other people or their property.
PREPARATION
• Evaluate the terrain to determine what
accessories and attachments are needed to
properly and safely perform the job. Use
only accessories and attachments approved
by ENCORE
• The use of personal protective equipment,
such as (but not limited to) safety glasses,
hearing protection, substantial footwear and
long trousers is highly recommended.
CAUTION
This machine produces sound levels in
excess of 85 dBA at the operator’s ear and
can cause hearing loss through extended
periods of exposure.
Wear hearing protection when operating this
machine.
• Thoroughly inspect the area where the
equipment is to be used and remove all
stones, sticks, wires, bones, and other
foreign objects which may damage the
equipment or cause personal injury to
operator or bystanders.

• Check that the operator’s presence controls,
safety switches, and shields are attached
and functioning properly. Do Not operate
unless they function properly.
DANGER
In certain conditions gasoline is extremely
flammable and highly explosive.
A fire or explosion from gasoline can burn
you, others and cause property damage.
• Refuel outdoors, on level ground while
engine is cold.
• Never remove fuel cap or add fuel when
engine is running or when engine is hot.
• Never fill the fuel tank so that gasoline level
rises above the bottom of the filler neck to
allow for gasoline expansion and prevent
fuel spillage.
• If fuel is spilled, DO NOT attempt to start the
engine. Move away from the area of the
spill and avoid creating any source of
ignition until fuel vapors have dissipated.
• Do not smoke while refueling and stay away
from an open flame or where gasoline
fumes may be ignited by spark.
• Do not operate without entire exhaust
system in place and in proper working
condition.
• Do not place any equipment that is leaking
gasoline in an enclosed trailer.
• Be sure all fuel tanks and gasoline storage
containers have proper caps installed to
prevent spillage and minimize vapor
escaping into the trailer.
DANGER
In certain conditions during fueling, static
electricity can be released causing gasoline
vapors to ignite.
A fire or explosion from gasoline can burn
you, others, and cause property damage.
• Purchase and store gasoline only in an
approved container
• Always place gasoline containers on the
ground away from your vehicle while 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
refuel the equipment with its wheels 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 rim of
the fuel tank or container opening at all
times until fueling is complete.
WARNING
Gasoline is harmful or fatal if swallowed.
Long-term exposure to vapors and failure to
use caution may cause serious injury or
illness.
• Avoid prolonged breathing of vapors.
• Keep face away from nozzle and gas
tank/container opening.
• Keep away from eyes and skin.
• Never siphon by mouth.

OPERATION
Although hazard control and accident
prevention are partially dependent upon the
design and configuration of the equipment,
these factors are also dependent upon the
awareness, concern and proper training of the
personnel involved in the operation, transport,
maintenance and the storage of the equipment.
It is essential that all Operator Safety
Mechanisms be connected and in operating
condition prior to use for mowing.
WARNING
Operating engine parts, especially the
muffler, become extremely hot. Severe
burns can occur on contact and debris,
such as leaves, grass, brush, etc. can catch
fire.
• Allow engine parts, especially the
muffler, to cool before touching.
• Remove accumulated debris from
muffler and engine area.
WARNING
Engine exhaust contains carbon monoxide,
which is an odorless deadly poison that can
kill you.
Do Not run engine indoors or in a small
confined area where dangerous carbon
monoxide fumes can collect.
• Operate only in daylight or good artificial
light, keeping away from holes and hidden
hazards.
• Be sure all drives are in neutral and parking
brake is engaged before starting engine.
• Never raise deck with blades running.
• Never operate the mower with damaged
guards, shields, or covers. Always have
safety shields, guards, switches and other
devices in place and in proper working
condition.
• Stop engine, wait for all moving parts to
stop and engage parking brake:
o Before refueling
o Before dumping the grass catcher
o Before making height adjustments
• Park machine on level ground. Stop
engine, wait for all moving parts to stop,
remove key and engage parking brake:
o Before checking, cleaning or working
on the mower.
o After striking a foreign object or
machine develops an abnormal
vibration (inspect machine for
damage and repair before resuming
operation)
o Before clearing blockages
o Before leaving the operator position
• Never mow with the discharge deflector
raised, removed or altered unless there is a
grass collection system or mulch kit in place
and working properly.
• Do Not change the engine governor setting
or over speed the engine.

WARNING
Hands, feet, hair, clothing, or accessories
can become entangled in rotating parts.
Contact with rotating parts can cause
traumatic amputation or severe lacerations.
Do Not operate the machine without guards,
shields, and safety devices in place and
working properly.
Keep hands, feet, hair, jewelry, or clothing
away from rotating parts.
DO NOT operate the mower when people,
especially children, or pets are in the area.
• Stop the blades, slow down, and use
caution when transporting the mower to and
from the area to be mowed or crossing
surfaces other than grass.
• Do not operate the mower under the
influence of alcohol or drugs.
• Be alert, slow down and use caution when
making turns. Look behind and to the side
before changing directions.
• Use extreme care when loading and
unloading the machine into a trailer or truck.
• Be aware of the mower discharge path and
direct discharge away from others.
• Use care when approaching blind corners,
shrubs, trees, or other objects that may
obscure vision.
SLOPE OPERATION
Use extreme caution when mowing and/or
turning on slopes as loss of traction and/or tipover could occur. The operator is responsible
for the safe operation on slopes.
DANGER
Mowing on wet grass or steep slopes can
cause sliding and loss of control.
• Mow across slopes, never up and down.
• Do Not mow slopes when grass is wet.
• Do Not mow near drop-offs or near water.
• Do Not mow slopes greater than 15
degrees.
• Reduce speed and use extreme caution on
slopes.
• Avoid sudden turns or rapid speed changes.
• Remove or mark obstacles such as rocks,
tree limbs, etc. from the mowing area. Tall
grass can hide obstacles.
• Be aware that operating on wet grass,
across steep slopes or downhill may cause
the mower to lose traction. Loss of traction
to the drive wheels may result in sliding and
a loss of braking and steering.
• Watch for ditches, holes, rocks, dips and
rises that change the operating angle, as
rough terrain could overturn the machine.
• Always avoid sudden starting or stopping on
a slope. If tires lose traction, disengage the
blades and proceed slowly off the slope.
• Use extreme care with grass catchers or
attachments. These can change the
stability of the machine and cause loss of
control.
