FUEL
• Gasoline is very flammable. Avoid smoking or bringing any
flame or sparks near fuel. Make sure to stop the engine and
allow it 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.
■
GASOLINE REQUIREMENTS
• All 2-Stroke RedMax Products are powered by RedMax
Professional-Commercial Duty, Hi-Performance, Hi-RPM,
Air
Cooled
2-Stroke engines.
RedMax – 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 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 "Max Life", 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 (Mid grade or Premium)
clean gasoline. Gasoline may contain maximum of 10% Ethanol
(grain alcohol) or up to 15% MTBE (Methyl tertiary-butyl ether).
Gasoline containing Methanol (Wood Alcohol) is
NOT
approved.
• 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.
• 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

WARNING
lines or fuel tank of the engine.
• Failures caused by operating engines on gasoline with octane
rating lower than 89 are not covered by the RedMax Two-
Stroke engine warranty.
• Alternative Fuels (Not Gasoline)
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 "Max Life", Synthetic blend Premium Air-
Cooled two-stroke engine oil or oil certified to ISO-L-
EGD
(ISO/CD1378) standard AND one that is JASO-
FD
registered.
RedMax Air-Cooled "Max Life", Synthetic blend Premium two
stroke engine oil and ISO-L-
EGD
(ISO/CD1378) AND JASO-
FD
oils are fully compatible with gasoline's containing 10% Ethanol.
RedMax Air-Cooled "Max Life", 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".
• Engine problems due to inadequate lubrication caused by
failure to use ISO-L-
EGD
certified and JASO
FD
registered oil
such as "MaxLife", RedMax Synthetic blend Premium 2-stroke
oil
WILL VOID THE REDMAX TWO-STROKE ENGINE
WARRANTY.
• Do not use NMMA (National Marine Manufacturers
Association), BIA (Boating Industry Association), and TCW (two
cycle water cooled) oils designed for MoPeds or Outboard,
water cooled Marine Engines. Do not use API (American
Petroleum Institute), TC (Two Cycle) labeled oils. The API-TC
