FUEL HANDLING

English – 17

Fuel

Note! The machine is equipped with a two-stroke engine

and must always be run using a mixture of gasoline and

two-stroke oil. It is important to accurately measure the

amount of oil to be mixed to ensure that the correct

mixture is obtained. When mixing small amounts of fuel,

even small inaccuracies can drastically affect the ratio of

the mixture.

Gasoline

• Use good quality unleaded gasoline.

• CAUTION! Engines equipped with catalytic

converters must be run on unleaded fuel

mixtures.

Leaded gasoline will destroy the catalytic

converter and it will no longer serve its purpose.

Gasoline requirements

• All 2-Stroke RedMax products are powered by

Zenoah Professional-Commercial Duty, Hi-

Performance, Hi-RPM, Air Cooled 2-Stroke engines.

RedMax/Zenoah – Hi-Performance 2-stroke engines

produce higher HP outputs as compared to standard

Home Owner Duty or Light Commercial Duty

production engines offered by most manufacturers.

• Exhaust emission are controlled by the fundamental

engine parameters and components (eq. carburation,

ignition timing and port timing) without addition of any

major hardware or the introduction of an inert material

during combustion.

• The RedMax/Zenoah engines are registered and

certiﬁed with CARB (California Air Resources Board)

and EPA (Environmental Protection Agency) to

operate on CLEAN Mid-grade 89 octane or Premium,

unleaded (lead-free) gasoline and RedMax air-cooled

"MaxLife", synthetic blend Premium two-stroke engine

oil mixed at 50:1 ratio.

• Unleaded gasoline is recommended to reduce the

contamination of the air for the sake of your health and

the environment.

• This Hi-Performance Air Cooled 2-stroke Engine

requires the use of Minimum 89 Octane (R+M)/2

(Midgrade or Premium) clean gasoline. Gasoline may

contain maximum of 10% Ethanol (grain alcohol) or up

to 15% MTBE (Methyl tertiarybutylether). Gasoline

containing Methanol (Wood Alcohol) is NOT

approved.

CAUTION! Gasoline with an octane rating lower than 89

will greatly increase the engines operating temperature.

Low octane gasoline will cause detonation (knock)

resulting in piston seizures and major internal engine

components damage.

Poor quality gasolines or oils may damage sealing rings,

fuel lines or fuel tank of the engine.

CAUTION! Alternative fuels, such as E-15 (15%

ethanol), E-20 (20% ethanol), E-85 (85% ethanol) are

NOT classiﬁed as gasoline and are NOT approved for use

in RedMax 2-stroke gasoline engines. Use of alternative

fuels will cause major engine performance and durability

problems such as: improper clutch engagements,

overheating, vapor lock, power loss, lubrication

deﬁciency, deterioration of fuel lines, gaskets and internal

carburetor components, etc... Alternative fuels cause high

moisture absorption into the fuel/oil mixture leading to oil

and fuel separation.

Oil requirements

• Use only RedMax "MaxLife", Synthetic blend

Premium air-cooled two-stroke engine oil or oil

certiﬁedto ISO-L-EGD (ISO/CD1378) standard AND

one that is JASO-FD registered. RedMax air-cooled

"MaxLife", Synthetic blend Premium two stroke

engine oil and ISO-L-EGD (ISO/CD1378) AND JASO-

FD oils arefully compatible with gasoline’s containing

10% Ethanol. RedMax air-cooled "MaxLife",

Synthetic blend Premium two stroke engine oil and

ISO-L-EGD (ISO/CD1378) AND JASO-FD oils are

Universal and should be mixed at 50:1 ratio for all 2

stroke air cooled engines sold in the past regardless

of mixing ratios speciﬁed in those manuals.

• If the oil is registered with JASO, the JASO Logo with

FD and registration number will be displayed on the

container. The highest JASO rating is "FD", which

equals the ISO-L-EGD rating. Lower ratings are "FC",

"FB" and "FA".

WARNING! Always ensure there is

adequate ventilation when handling fuel.

WARNING! Gasoline is very ﬂammable.

Avoid smoking or bringing any ﬂame or

sparks near fuel. Make sure to stop the

engine and allow it to cool before

refueling the unit. Select outdoor bare

ground for fueling and move at least 10 ft

(3 m) away from the fueling point before

starting the engine.

IMPORTANT! If octane rating of the Mid Grade gasoline

in your area is lower than 89 Octane use Premium

Unleaded Gasoline. The majority of all 2-stroke engine

manufacturers in the USA and Canada recommend

using gasoline with 89 Octane or higher.

IMPORTANT! Failures caused by operating engines on

gasoline with octane rating lower than 89 are not

covered by the RedMax Two-Stroke engine warranty.
