SAFETY RULES
The following safety instructions are based
on the B71.4 specifications of the American
National Standards Institute and ISO 5395 in
effect at the time of production.
Training
Read, understand, and follow all instructions
on the machine and in the manuals before
starting.
Be sure the area is clear of bystanders and
pets before operating. Stop machine if
anyone enters the area.
Improper use of power equipment can cause
serious permanent injury or death to the
operator or a bystander.
Understand:
• How to operate all controls
• The functions of all controls
• How to STOP in an Emergency
• Braking and steering characteristics
• Turning radius and clearances
If the operator or the mechanic cannot read
the manual, it is the owner’s responsibility to
explain it to them.
Always train any inexperienced operators
and require them to read and understand all
manuals and decals.
Only allow responsible adults, who are
familiar with the instructions, to operate this
machine.
Only the user can prevent and is responsible
for accidents or injuries occurring to
themselves, other people or property.
Operator Age
Do not allow children under the age of 18 to
operate any outdoor power equipment.
Local regulations may restrict the age of the
operator.
Data indicates 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 mower safely enough to
protect themselves and others
from serious injury.
Children
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.
Be alert and turn machine off if a child enters
the area.
Before and while backing, look behind and
down for small children.
Never carry children, even with the blade(s)
shut off. They may fall off and be seriously
injured or interfere with safe machine
operation. Children who have been given
rides in the past may suddenly appear in the
mowing area for another ride and be run
over or backed over by the machine.
Never allow children to operate the machine.
Use extreme care when approaching blind
corners, shrubs, trees, or other objects that
may block your view of a child.
Keep children out of the mowing area and in
the watchful care of a responsible adult
other than the operator.
Personal Protection
DO NOT wear loose clothing or jewelry and
tie back hair that may get caught in rotating
parts.
Wear adequate outer garments.

those you can safely control and the unit can
safely handle.

EN - 7
Operating Conditions
Always check overhead and side clearances
carefully before operation.
Watch for traffic when operating near or
crossing roadways.
Clear the area of objects such as rocks,
wire, toys, etc., which could be thrown by the
blades.
Check for weak spots on docks, ramps or
floors. Avoid uneven work areas and rough
terrain. Stay alert for hidden hazards or
traffic.
Use care when approaching blind corners,
shrubs, trees or other objects that may
obscure vision.
Dust, smoke, fog, etc. can reduce vision and
cause an accident.
Operate machine only in daylight or good
artificial light.
Slope Operation
Slopes are a major factor related to loss of
control and tip-over accidents, which can
result in severe injury or death. Operation on
all slopes requires extra caution. If you
cannot back up the slope or if you feel
uneasy on it, do not mow it.
DO NOT operate on slopes of more than
15°.
Mow up and down slopes, not across.
Watch for holes, ruts, bumps, rocks, or other
hidden objects. Uneven terrain could
overturn the machine. Tall grass can hide
obstacles.
Do not mow on moist or wet grass. Tires
may lose traction causing a loss of control.
Use extra care while operating machine with
grass catchers or other attachments; they
can affect the stability of the machine. Do
not use on steep slopes.
Keep all movements on the slope slow and
gradual. Do not make sudden changes in
speed or direction, which could cause the
machine to roll over.
Avoid starting, stopping, or turning on a
slope. If the tires lose traction, disengage
the blade(s) and proceed slowly straight
down the slope.
Operation on slopes may lead to loss of
steering control. When operating on slopes
be prepared to react to an emergency
situation:
• Return steering levers to neutral
position.
• Immediately set parking brake.
• Turn off PTO and engine.
DO NOT try to stabilize the machine by
putting your foot on the ground.
DO NOT park on slopes unless necessary.
When parking on slope always chock or
block wheels. Always set parking brake.
Choose a low ground speed so you will not
have to stop or shift while on a slope.
DO NOT operate near drop-offs, ditches, or
embankments. Unit can suddenly turn over if
a wheel is over the edge of a cliff or ditch, or
if an edge caves in.
Do not bypass transmission or allow
transmission to free-wheel when on a slope.
Fuel
To avoid personal injury or property damage,
use extreme care in handling gasoline.
Gasoline is extremely flammable and the
vapors are explosive.
Ethanol blends must not exceed E10. Higher
ethanol content may cause your
machine to run hotter and damage your
engine.
Replace fuel cap securely and clean up
spilled fuel before starting engine.
Extinguish all cigarettes, cigars, pipes, and
other sources of ignition.
Use only an approved gasoline container.
Never store the machine or fuel container
where there is an open flame, spark, or pilot
light such as on a water or space heater or
other appliances.
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.
Never fuel the machine indoors.
Never remove gas cap or add fuel with the
engine running. Allow engine to cool before
fueling.
Fuel is highly flammable and its vapors are
explosive. Handle with care. Use only an
approved gasoline container with an
appropriately sized dispensing spout.
NO smoking, NO sparks, NO flames.

EN - 8
Remove gas-powered equipment from the
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.
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.
Never overfill fuel tank. Replace gas cap
and tighten securely.
If fuel is spilled on clothing, change clothing
immediately.
Accessories
Follow the manufacturer’s recommendation
for wheel weights or counterweights
Check grass catcher components and the
discharge guard frequently and replace with
the manufacturer’s recommended parts,
when necessary.
Use only Ariens Company-recommended
attachments that are appropriate to your use
and can be used safely in your application.
Batteries
Avoid Electric Shock. Objects contacting
both battery terminals at the same time may
result in injury and unit damage. DO NOT
reverse battery connections.
Reverse connections may result in sparks
which can cause serious injury. Always
connect positive (+) lead of charger to
positive (+) terminal, and negative (-) lead to
negative (-) terminal.
ALWAYS disconnect negative (-) cable
FIRST and positive (+) cable SECOND.
ALWAYS connect positive (+) cable FIRST,
and negative (-) cable SECOND.
Explosive Gases from battery can cause
death or serious injury. Poisonous battery
fluid contains sulfuric acid and its contact
with skin, eyes or clothing can cause severe
chemical burns.
No flames, No sparks, No smoking near
battery.
ALWAYS wear safety glasses and protective
gear near battery. Use insulated tools.
ALWAYS keep batteries out of reach of
children.
Battery posts, terminals and related
accessories contain lead and lead
compounds, chemicals known to the State of
California to cause cancer and reproductive
harm. Wash hands after handling.
Service
Maintain or replace safety and instruction
labels, as necessary.
Keep unit free of debris. Clean up oil or fuel
spills.
ALWAYS block wheels and know all jack
stands are strong and secure and will hold
weight of unit during maintenance.
Release any pneumatic or hydraulic
pressure from components slowly.
NEVER attempt to make any adjustments to
unit while engine is running (except where
specifically recommended). Stop engine,
remove key or spark plug wire and wait for
all moving parts to stop before servicing or
cleaning.
Lower cutting deck unless a positive
mechanical lock is used.
Allow engine to cool before servicing.
Moving parts can cut or amputate fingers or
a hand. On multiblade mowers, rotation of
one blade will cause all blades to rotate.
Never weld or straighten mower blades.
Never make adjustments or repairs with the
engine running.
Mower blades are sharp. Wrap the blade or
wear gloves, and use extra caution when
servicing them.
ALWAYS keep body and hands away from
pin holes or nozzles which eject hydraulic
fluid under pressure.
Transporting Unit
Use extra care when loading or unloading
the machine into a trailer.
Secure unit chassis to transport vehicle.
Never secure from rods or linkages that
could be damaged.
Do not transport machine while engine is
running.
ALWAYS turn off power to attachment and
shut off fuel when transporting unit.

EN - 9
Storage
NEVER store unit with fuel in fuel tank,
inside a building where any ignition sources
are present.
