Emission Control System

Certification Label

NOTE: Tampering with emission controls and
components by unauthorized personnel may

result in severe fines or penalties. Emission
controls and components can only be
adjusted by EPA and/or CARB authorized
service centers. Contact your Ariens

Equipment Retailer concerning emission
controls and component questions.

Fuel is highly flammable and its vapors can
explode. ONLY use approved fuel containers.

NO Smoking!
NO Sparks!

GB-7

NO Flames!

Allow engine to cool before filling fuel

tank.

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.

When practical, remove gas-powered
equipment from the truck or trailer and refuel
it on the ground. If this is not possible, then
refuel such equipment on a trailer 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
fueling is complete. Do not use a nozzle lock-
open device.

Check fuel supply before starting engine.

DO NOT fill gasoline tank indoors, when
engine is running, or while engine is hot.

Allow engine to cool several minutes before
removing fuel cap.

DO NOT overfill. Allow about 1/4" (6 mm) of
tank space for fuel expansion.

Replace gasoline tank cap securely and
clean any spilled fuel before starting engine.

If fuel is spilled on clothing, change clothing
immediately.

NEVER store fuel inside where there is an
open flame, such as a water heater.

ALWAYS drain fuel outdoors away from
ignition sources.

ALWAYS shut off engine, and remove key,
and close fuel shutoff valve when transporting

unit on a truck or trailer.
Avoid Electric Shock. DO NOT disconnect

wire from spark plug while engine is running.

Do NOT put battery in fire or mutilate.

Explosive Gases!

NO flames, NO sparks, NO smoking, near
battery.

Poisonous battery fluid contains sulfuric acid.
Contact with skin, eyes or clothing can cause

severe chemical burns.
ALWAYS wear safety glasses and protective

gear near battery.
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.

GASOLINE

IMPORTANT: ALWAYS use gasoline that

meets the following guidelines:

Clean, fresh gasoline.
A minimum of 87 octane/87 AKI (91

IRON). High altitude use may require a

different octane. Consult your engine
manual.

Gasoline with up to 10% ethanol
(gasohol) or up to 15% MTBE (methyl

tertiary butyl ether) is acceptable.

Use of any gasoline other than those

approved above may 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.

Fuel Stabilizer

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 add fuel to fuel tank:

1. Put unit in open or well-ventilated area.

2. Stop engine and allow to cool.

3. Clean fuel cap and surrounding area.

4. Remove cap.

IMPORTANT: See engine manual for correct
type and grade of fuel.

5. Fill fuel tank to within 1/4 in. (0.63 cm)
below bottom of filler neck with unleaded

gasoline. See SPECIFICATIONS on
page 25.

6. Replace fuel cap and tighten.

7. ALWAYS clean any spilled fuel.

CAUTION: AVOID INJURY. Read
and understand the entire Safety

section before proceeding.

Ariens Dealers will provide any service, parts
or adjustments which may be required to

keep your unit operating at peak efficiency.
Should engine require service, contact an

Ariens Dealer or an authorized engine

MAINTENANCE SCHEDULE

NOTE: Some working conditions (heavy
loads, high ambient temperatures, dusty

conditions, or airborne debris) may require

more frequent service.
See engine manual for further maintenance

and troubleshooting information.

Do not mow too fast.
Mow with engine at full throttle. Discharge
