EN - 7

Operating Conditions

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.

ALWAYS check overhead and side

clearances carefully before operation.

Watch for traffic when operating near or

crossing roadways.

Prior to operation, ensure the area is cleared

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.

Only operate in good light, keeping away

from holes and hidden hazards.

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

20°. This maximum degree of operation is

without attachments.

Do not operate on slopes of more than 10°

with attachments such as grass catchers

installed.

Mow across slopes, not up and down.

DO NOT operate the mower on slopes at all

when the grass is wet.

DO NOT operate on slopes steeper than

you can feel secure about the traction of the

tires and the stability of the mower.

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.

Slow down and use caution when making

turns and when changing directions on

slopes. Keep all movements on the slope

slow and gradual. Sudden changes in speed

or direction 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 drive control grip to neutral

position.

• Immediately engage parking brake.

• Turn off PTO and engine.

DO NOT park on slopes unless necessary.

When parking on slope ALWAYS chock or

block wheels. ALWAYS engage parking

brake.

Choose a slow ground speed so you will not

have to stop or shift while on a slope.

Slow down and use extra care on hillsides.

Be sure to travel in the recommended

direction on hillsides. Turf conditions can

affect the machine’s stability. Use caution

while operating near drop-offs.

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.

Secure fuel cap and clean up spilled fuel

before starting engine.

Extinguish all cigarettes, cigars, pipes, and

other sources of ignition.

EN - 8

Use only an approved fuel 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 refuel the machine indoors.

NEVER remove fuel cap or add fuel with the

engine running. Allow engine to cool before

refueling.

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 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. Reinstall fuel cap

and tighten securely.

If fuel is spilled on clothing, change clothing

immediately.

DO NOT OVERFILL! This equipment and/or

its engine may include evaporative

emissions control system components,

required to meet EPA and/or CARB

regulations, that will only function properly

when the fuel tank has been filled to the

recommended level. Overfilling may cause

permanent damage to evaporative

emissions control system components.

Filling to the recommended level ensures a

vapor gap required to allow for fuel

expansion. Pay close attention while filling

the fuel tank to ensure that the

recommended fuel level inside the tank is

not exceeded. Use a portable gasoline

container with an appropriately sized

dispensing spout when filling the tank. DO

NOT use a funnel or other device that

obstructs the view of the tank filling process.

Towing

DO NOT attach towed equipment or

accessories, other than a sulky.This vehicle

is not designed to tow anything other than

sulkies.

Accessories

Attachments reduce the maximum operating

slope angle. DO NOT operate on slopes

over 10° when operating with attachments.

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.

Charge batteries in an open, well-ventilated

area, away from spark and flames. Unplug

charger before connecting or disconnecting

from battery. ALWAYS wear protective

clothing and safety glasses near battery and

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.

EN - 9

Service

The use of non-genuine replacement parts

or accessories could adversely affect

machine operation and safety.

DO NOT change engine governor setting or

overspeed the engine.

Park machine on level ground. NEVER allow

untrained personnel to service machine.

Disconnect battery or remove spark plug

wire before making any repairs. Disconnect

the negative terminal first and the positive

last. Reconnect positive first and negative

last.

Keep all parts in good working condition and

all hardware tightened. Replace all worn or

damaged decals.

Keep unit free of debris. Clean up oil or fuel

stored energy.

ALWAYS keep body and hands away from

pin holes or nozzles which eject hydraulic

fluid under pressure.

NEVER attempt to make any adjustments or

repairs to unit while engine is running

(except where specifically recommended).

Disengage drives, lower implement, engage

parking brake, stop engine and remove key

or disconnect spark plug wire. Wait for all

moving parts to stop and for hot surfaces to

cool before adjusting, cleaning or repairing

unit.

Keep hands and feet away from moving

parts. If possible, DO NOT make

adjustments with the engine running.

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.

Use care when checking blades. Wrap the

blade(s) or wear gloves and use caution

when servicing them. Replace damaged

blades. NEVER straighten or weld blades.

Transporting Unit

Use care when loading or unloading the

machine into a trailer or truck.

Use full-width ramps for loading machine

into trailer or truck.

Secure unit chassis to transport vehicle.
