Safe Practices for Ride-On Mowers
If used improperly, this 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. Use only for purposes
intended as set forth in the Operator's
Manual. Other use is improper and may
cause serious injury or death.
General Information
Read, understand, and follow instructions
and warnings in this manual and on the
machine, engine and attachments.
Only allow operators, who are responsible,
trained, familiar with the instructions, and
physically capable to operate the machine.
DO NOT carry passengers and keep people
or pets away from the mowing area.
DO NOT operate the machine while
physically or mentally impaired, feeling tired,
ill or under the influence of alcohol or drugs.
Follow the manufacturer’s recommendation
for wheel weights or counterweights.
DO NOT touch parts which are hot. Allow
parts to cool.
Preparation Before Operating
Inspect unit before each use for missing or
damaged decals and shields, correctly
operating safety interlock system, ROPS
and deterioration of grass catchers. Replace
or repair as needed.
Clear the operating area of all objects which
could be thrown by or interfere with
operation of the machine.
Keep the area of operation clear of all
bystanders, particularly small children. Stop
the machine and attachment(s) if anyone
enters the area
DO NOT operate the machine without the
entire grass catcher, discharge chute, or
other safety devices in place and functioning
properly. Check frequently for signs of
damage, wear or deterioration and replace
as needed.
EN - 6
NEVER tamper with safety devices. Check
their proper operation regularly. NEVER do
anything to interfere with the intended
function of a safety device or to reduce the
protection provided by the safety device.
Check parking brake operation frequently.
Adjust and service as required.
Wear appropriate personal protective
equipment such as safety glasses, hearing
protection, and substantial footwear. DO
NOT mow barefoot or while wearing
sandals.
Operating
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. Manuals are available in
other languages at www.ariens.com.
Only run the engine in well ventilated areas.
Exhaust gases contain carbon monoxide, an
odorless deadly poison.
Only operate the machine in daylight or
good artificial light.
Avoid holes, ruts, bumps, rocks and other
hazards. Uneven terrain could overturn the
machine, or cause operator to lose their
balance, footing and/or control of the mower.
DO NOT put hands or feet near rotating
parts or under the machine. Keep clear of
the discharge opening at all times.
Avoid slippery surfaces. ALWAYS be sure of
your footing.
Stop engine before removing grass catcher
or unclogging chute.
DO NOT direct discharge material toward
anyone. Avoid discharging material against
a wall or obstruction. Material may ricochet
back toward the operator. Stop the blade(s)
when crossing gravel surfaces. DO NOT
mow into roads or across sidewalks.
DO NOT leave a running machine
unattended. ALWAYS park on level ground,
disengage the attachment, set parking
brake, stop engine and remove key (if
applicable) before leaving the operator's
position.
DO NOT mow in reverse unless absolutely
necessary. ALWAYS look down and behind
before and while backing.
Lightning can cause severe injury or death.
If lightning is seen or thunder is heard in the
area, DO NOT operate the machine; seek
shelter.
If you strike a foreign object, stop and
inspect the machine. Repair, if necessary,
before restarting.
ALWAYS check overhead and side
clearances carefully before operation. Keep
in mind that your mower deck may be wider
than your track width.
Children Specific
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.
Keep children out of the operating area and
under the watchful care of a responsible
adult other than the operator.
Do not carry children, even with the blade(s)
shut off. Children could fall off and be
seriously injured or interfere with safe
machine operation. Children who have been
given rides in the past could suddenly
appear in the mowing area for another ride
and be run over or backed over.
DO NOT allow children under the age of 18
to operate any outdoor power equipment.
Slope Specific
Slopes are a major factor related to
accidents. Operation on slopes requires
extra caution. If you feel uneasy on a slope
DO NOT mow it. Use the parking brake for
emergency stops.
DO Not operate on slopes of more than 15°.
Do not mow within 1.2 M (4 feet) of a drop
off. Do not mow within 1.2 M (4 feet) of a
pond or other waterway.
The primary hazard of slope operation is
loss of control and/or roll over.
EN - 7
Mow up and down slopes, NEVER across.
Exercise caution when changing direction
on slopes. Use caution while operating near
dropoffs.
Avoid mowing wet grass. Wet surfaces can
cause a loss of traction and control.
DO NOT operate machine under any
condition where traction, steering, or stability
is in question. Tires could slide even if the
wheels are stopped.
Always keep the machine in gear when
going down slopes. Do not coast downhill.
Avoid starting and stopping on slopes. Avoid
making sudden changes in speed or
direction. Make turns slowly and gradually.
Use extra care while operating machine with
a grass catcher or other attachment(s). They
can affect the stability of the machine.
Fire and Fuel Specific
Extinguish all cigarettes, cigars, pipes and
other sources of ignition.
Use only an approved fuel container.
DO NOT remove fuel cap or add fuel with
the engine running or while hot.
DO NOT refuel indoors or in enclosed
spaces.
DO NOT store the machine or fuel container,
or refuel, where there is an open flame,
spark, or pilot light such as on a water
heater or other appliance.
If fuel is spilled, DO NOT attempt to start the
engine and avoid creating any source of
ignition until fuel vapors have dissipated.
To help prevent fires: keep machine free of
grass, leaves, or other debris build up; clean
up oil or fuel spillage and remove any fuel
soaked debris; allow engine to cool before
storing.
Use extra care in handling gasoline and
other fuels. They are flammable and vapors
are explosive.
Service
Keep machine in good working order.
Replace worn or damaged parts.
Use caution when servicing blades. Wrap
the blade(s) or wear gloves. Replace
damaged blades. DO NOT repair or alter
blade(s).
