and Prevent
Accidents
Protect Children:
•Tragic accidents can occur if the
operator is not alert to the presence of
children. Children are often attracted
to lawn-mowing machines and
mowing activity. Stay alert to the
presence of children. Never assume
that children will remain where you last
saw them.
•Keep children indoors, out of the
mowing area, and in the watchful eye
of a responsible adult, other than the
operator, when a mower is being
operated.
•Be alert and turn mower off if a child
enters the work area. They don’t
understand the dangers of rotating
blades or the fact that the operator is
unaware of their presence.
•Never allow a child or an untrained
person to operate the machine.
•Use extra care when approaching
blind corners, shrubs, trees, or other
objects that may block your view of a
child.
Checking Wheel Hardware
•A serious accident could occur
causing serious injury if wheel
hardware is not tight.
•Check wheel hardware tightness often
during the first 100 hours of operation.
•Wheel hardware must be tightened to
specified torque using the proper
procedure anytime it is loosened.
Wear
Appropriate
Clothing
•Always wear
safety goggles,
or safety
glasses with

•Before servicing machine or
attachment, carefully release pressure
from any components with stored
energy, such as hydraulic components
or springs.
•Release hydraulic pressure by
lowering attachment or cutting units to
the ground or to a mechanical stop
and move hydraulic control levers
back and forth.
•Disconnect battery or remove spark
plug (for gas engines) before making
any repairs. Disconnect the negative
terminal first and the positive last.
Reconnect positive first and negative
last.
•Use care when checking blades. Wrap
the blades or wear gloves, and use

•Charge batteries in an open well
ventilated area, away from spark and
flames. Unplug charger before
connecting or disconnecting from
battery. Wear protective clothing and
use insulated tools.
•Keep all parts in good working
condition and all hardware tightened.
Replace all worn or damaged decals.
•Check grasscatcher components and
the discharge guard frequently and
replace with manufacturer’s
recommended parts, when necessary.
Grasscatcher components are subject
to wear, damage, and deterioration
which could expose moving parts or
allow objects to be thrown.
•Keep all nuts and bolts t ight, especially
blade attachment bolts, to be sure the
equipment is in safe working condition.
•Check brake operation frequently.
Adjust and service as required.
•On multi-bladed machines, take care
as rotating one blade can cause other
blades to rotate.
Avoid High Pressure Fluids
•Hydraulic hoses and lines can fail due
to physical damage, kinks, age, and
exposure. Check hoses and lines
regularly. Replace damaged hoses
and lines.
•Hydraulic fluid connections can loosen
due to physical damage and vibration.
Check connections regularly. Tighten
loose connections.
•Escaping fluid under pressure can
penetrate the skin causing serious
injury. Avoid the hazard by relieving
pressure before disconnecting
hydraulic or other lines. Tighten all
connections before applying pressure.
•Search for leaks with a piece of
cardboard. Protect hands and body
from high pressure fluids.
•If an accident occurs, see a doctor
immediately. Any fluid injected into the
skin must be surgically removed within
a few hours or gangrene may result.
Doctors unfamiliar with this type of
injury should reference a
knowledgeable medical source.
Prevent Fires
•Machine fires and structure fires can
occur if a machine is stored before
allowing it to cool, or if debris is not
removed from around the engine and
muffler, or if stored near combustible
materials.
•Remove grass and debris from engine
compartment and muffler area, before
and after operating machine,
especially after mowing or mulching in
dry conditions.
GB - 10
•Empty the grasscatcher completely
before storing. Always shut off fuel
when storing or transporting machine,
if the machine has a fuel shutoff.
•Do not store machine near an open
flame or source of ignition, such as a
water heater or furnace.
•Check fuel lines, tank, cap, and fittings
frequently for cracks or leaks. Replace
if necessary.
Tire Safety
Explosive separation of
a tire and rim parts can
cause serious injury or
death:
•Do not attempt to
mount a tire without the
experience to perform the job.
•Always maintain the correct tire
pressure. Do not inflate the tires above
the recommended pressure. Never
weld or heat a wheel and tire
assembly. The heat can cause an
increase in air pressure resulting in a
tire explosion. Welding can structurally
weaken or deform the wheel.
•When inflating tires, use a clip-on
chuck and extension hose long
enough to allow you to stand to one
side and NOT in front of or over the
tire assembly.
•Check tires for low pressure, cuts,
bubbles, damaged rims or missing lug
bolts and nuts.

the engine but move the machine
away from the area of spillage. Avoid
creating any source of ignition until
fuel vapors have dissipated.
•Never store the machine or fuel
container where there is an open
flame, spark, or pilot light such as on a
water heater or other appliance.
•Prevent fire and explosion caused by
static electric discharge. Static electric
discharge can ignite fuel vapors in an
ungrounded fuel container.
•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
fueling.
•Remove fuel-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 fuel
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 fuel
tank cap and tighten securely.
•Replace all fuel container caps
securely after use.
•Fuel is highly flammable and its
vapors are explosive. Handle with
care. Use only an approved gasoline

FILLING FUEL TANK
To add fuel to the fuel tank:
1. Clean fuel cap and surrounding area to
prevent dust, dirt, and debris from
entering fuel tanks.
2. Remove fuel cap.
IMPORTANT: Refer to Engine Manual for
correct type and grade of fuel.
3. Fill fuel tank to the bottom of filler neck.
SPECIFICATIONS on page 31 for
See
fuel tank capacity.
IMPORTANT: 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.
4. Replace fue l cap and tighten.
5. ALWAYS clean up spilled fuel.
GASOLINE
IMPORTANT: ALWAYS use gasoline that
meets the following guidelines:
•Clean, fresh gasoline.
•A minimum of 87 octane/87 AKI (91
RON). High altitude use may require a
different octane. Consult your engine
manual.
•Gasoline with up to 10% ethanol
(gasohol) or up to 10% MTBE (methyl
tertiary butyl ether) is acceptable.
•Use of any gasoline other than those
approved above will void the engine
warranty. If the pumps are not marked
for the content of alcohol or ethers,
check ethanol and MTBE levels with
the fuel supplier.
•Do not modify the fuel system to use
different fuels.
•Never mix oil and gasoline.
NOTE: All gasoline is not the same. If the
engine experiences starting or performance
problems after using a new gasoline, switch
to a different fuel provider or fuel brand.
IMPORTANT: Excessively oxygenated or
reformulated fuels (fuels blended with
alcohols or ethers) can damage the fuel
system or cause performance problems. If
any undesirable operating problems occur,
use a gasoline with a lower percentage of
alcohol or ether.
GB - 15
Page 16
Fuel Stabilizer
OG1410
Gasoline left in the fuel system for extended
periods without a stabilizer will deteriorate,
resulting in gum deposits in the system.
These deposits can damage the carburetor
and the fuel hoses, filter and tank. Prevent
deposits from forming in the fuel system
during storage by adding a quality fuel
stabilizer to the fuel. Follow the
recommended mix ratio found on the fuel
stabilizer container.

STORAGE
Fuel System
Gasoline left in the fuel system for extended
periods without a stabilizer will deteriorate,
resulting in gum deposits in the system.
These deposits can damage the carburetor
and the fuel hoses, filter and tank. Prevent
deposits from forming in the fuel system
during storage by adding a quality fuel
stabilizer to the fuel. Follow the
recommended mix ratio found on the fuel
stabilizer container.
To treat the fuel system for storage:
1. Add fuel stabilizer according to
manufacturers’s instructions.
2. Run engine for at least 10 minutes after
adding stabilizer to allow it to reach the
carburetor.
NEVER store the engine with fuel in the fuel
tank inside of a building with potential
sources of ignition.
WARNING: AVO ID INJURY. Read
and understand the entire Safety
section before proceeding.
Storage – Two Months or More
Check each item in the MAINTENANCE
SCHEDULE on page 21, but do not add
gasoline.
Clean the unit. T ouch up all scratched painted
surfaces.
IMPORTANT: Never spray unit with high-
pressure water or store unit outdoors. Store
unit in a cool, dry, protected location.
NOTE: Clean unit thoroughly with mild soap
and low pressure water and lubricate (
GENERAL LUBRICATION on page 22).
Touch up all scratched painted surfaces. Do
not allow gasoline or oil to remain on any
decals.

California Evaporative
Emission Control Warranty
Statement
YOUR WARRANTY RIGHTS AND OBLIGATIONS
The California Air Resources Board and Ariens Company are pleased to explain the
evaporative emission control system's warranty on your 2011 model year small off-road
equipment. In California, new equipment that use small off-road engines must be designed,
built, and equipped to meet the State's stringent anti-smog standards. Ariens Company must
warrant the evaporative emission control system on your small off-road equipment for the
period listed below provided there has been no abuse, neglect or improper maintenance of
your equipment.
Your evaporative emission control system may include parts such as: fuel tanks, fuel lines, fuel
caps, valves, canisters, filters, vapor hoses, clamps, connectors, and other associated
components.
Manufacturer’s Warranty Coverage:
This evaporative emission control system is warranted for two years. If any evaporative
emission-related part on your equipment is defective, the part will be repaired or replaced by
Ariens Company.
Owner's Warranty Responsibilities:
• As the small off-road equipment owner, you are responsible for the performance of the
required maintenance listed in your Owner's Manual. Ariens Company recommends that
you retain all receipts covering maintenance on your small off-road equipment, but Ariens
Company cannot deny warranty solely for the lack of receipts.
• As the small off-road equipment owner, you should however be aware that the Ariens
Company may deny you warranty coverage if your evaporative emission control system
part has failed due to abuse, neglect, or improper maintenance or unapproved
modifications.
• You are responsible for presenting your small off-road equipment to an authorized Ariens
service representative as soon as the problem exists. The warranty repairs should be
completed in a reasonable amount of time, not to exceed 30 days. If you have a question
regarding your warranty coverage, you should contact Ariens Company Technical Service
Center at 1-920-756-4688.
Defects Warranty Requirements:
(a) The warranty period begins on the date the small off-road equipment is delivered to an
ultimate purchaser.
(b) General Evaporative Emissions Warranty Coverage. Ariens Company warrants to the
ultimate purchaser and any subsequent owner that the evaporative emission control
system when installed was:
(1) Designed, built, and equipped so as to conform with all applicable regulations; and
(2) Free from defects in materials and workmanship that causes the failure of a warranted
part for a period of two years.
CARB_2011
34
Page 35
(c) The warranty on evaporative emissions-related parts will be interpreted as follows:
(1) Any warranted part that is not scheduled for replacement as required maintenance in
the written instructions must be warranted for the warranty period defined in
subsection (b)(2). If any such part fails during the period of warranty coverage, it must
be repaired or replaced by the Ariens Company. Any such part repaired or replaced
under the warranty must be warranted for a time not less than the remaining warranty
period.
(2) Any warranted part that is scheduled only for regular inspection in the written
instructions must be warranted for the warranty period defined in subsection (b)(2). A
statement in such written instructions to the effect of "repair or replace as necessary"
will not reduce the period of warranty coverage. Any such part repaired or replaced
under warranty must be warranted for a time not less than the remaining warranty
period.
(3) Any warranted part that is scheduled for replacement as required maintenance in the
written instructions must be warranted for the period of time prior to the first
scheduled replacement point for that part. If the part fails prior to the first scheduled
replacement, the part must be repaired or replaced by the Ariens Company. Any such
part repaired or replaced under warranty must be warranted for a time not less than
the remainder of the period prior to the first scheduled replacement point for the part.
(4) Repair or replacement of any warranted part under the warranty provisions of this
article must be performed at no charge to the owner at an authorized Ariens service
representative.
(5) Notwithstanding the provisions of subsection (4) above, warranty services or repairs
must be provided at authorized Ariens service representatives that are franchised to
service the subject small off-road equipment.
(6) The owner must not be charged for diagnostic labor that leads to the determination
that a warranted part is in fact defective, provided that such diagnostic work is
performed at a authorized Ariens service representative.
(7) Throughout the evaporative emission control system's warranty period set out in
subsection (b)(2), the Ariens Company must maintain a supply of warranted parts
sufficient to meet the expected demand for such parts.
(8) Manufacturer approved replacement parts must be used in the performance of any
warranty maintenance or repairs and must be provided without charge to the owner.
Such use will not reduce the warranty obligations of the manufacturer issuing the
warranty.
(9) The use of any add-on or modified parts will be grounds for disallowing a warranty
claim made in accordance with this article. The manufacturer issuing the warranty will
not be liable under this Article to warrant failures of warranted parts caused by the use
of an addon or modified part.
(10)The Ariens Company shall provide any documents that describe the warranty
procedures or policies within five working days of request by the Air Resources
Board.
