area, do not operate the machine; seek
shelter.
Operating Conditions
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. Stay behind the handle when the
engine (motor) is running.
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.
See manufacturer’s instructions for proper
operation and installation of accessories.
Only use accessories approved by the
manufacturer.
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 feel
uneasy on it, DO NOT mow it.
Mow across slopes, NEVER up and down.
Exercise caution when changing direction
on slopes.
Watch for holes, ruts, bumps, rocks, or other
hidden objects. Uneven terrain could cause
a slip and fall accident. Tall grass can hide
obstacles.
DO NOT mow wet grass or excessive steep
slopes. Poor footing could cause a slip and
fall accident.
DO NOT operate near drop-offs, ditches, or
embankments. You could lose your footing
or balance.
Fuel
To avoid personal injury or propertydamage,
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.
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.
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.

EN - 7
Accessories
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.
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.
Reverse connections may result in sparks
which can cause serious injury. ALWAYS
connect positive (+) lead of harness to
positive (+) terminal and negative (–) lead to
negative (–) terminal.
A frozen battery can explode and result in
death or serious injury. DO NOT charge or
jump start a battery containing frozen fluid.
Thaw the battery before puttingon a charger
or jump starting.
Service
Maintain or replace safety and instruction
labels, as necessary.
Keep unit free of debris. Clean up oil or fuel
spills.
DO NOT change engine governor setting or
overspeed the engine.
NEVER make any adjustments or repairs
with the engine (motor) running. *Disconnect
the spark plug wire and ground against
engine to prevent unintended starting.
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.
Mower blades are sharp. Wrap the blade or
wear gloves, and use extra caution when
servicing them.
The use of non-genuine replacement parts
or accessories could adversely affect
machine operation and safety.
Transporting Unit
Use extra care when loading or unloading
the machine onto a truck or 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 stop engine and shut off fuel when
transporting unit.
Storage
NEVER store unit with fuel in fuel tank,
inside a building where any ignition sources
are present.
Keep machine free of grass, leaves, or other
debris build-up. Clean up oil or fuel spillage
and remove any fuel-soaked debris. Allow
machine to cool before storing.
For extended storage, shut off fuel and
clean unit thoroughly. See engine manual for
proper storage.
