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.
!
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.
