FUEL HANDLING
Fuel
Note! The machine is equipped with a
2--stroke engine and must always be run us-
ing a mixture of gasol ine and two-stroke e n-
gine oil. It is important to accurately measure
theamountofoiltobemixedtoensurethat
the correct mixture is obtained. When mixing
small amounts of fuel, even small inaccura-
cies ca n d ra stica lly aff ect the r at io of the
mixture.
Gasoline
S Use good quality unleaded gasoline.
W ARNING: Always ensure there
is adequate ventilation when han-
dling 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 cool before refueling
the unit. Select outdoor bare
ground for fueling and move at
least 10 feet (3 meters) away from
the fueling point before starting
the engine.
Gasoline requirements
S All 2--stroke RedMax products are pow-
ered by professional-commercial duty,
hi--performance, hi--RPM, air cooled
2--s troke engines. RedMax hi--performa nce
2--s troke engines produce higher HP
outputs as compared to standard home
owner duty or light commercial duty
production engines offered by most
manufacturers.
S Exhaust emission are controlled by the
fundamental engine parameters and com-
ponents (eg. carburation, ignition timing
and port timing) without addition of any
major hardware or the introduction of an
inert material during combustion.
S The RedMax engines are registered and cer-
tified with CARB (California Air Resources
Board) and EP A (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 2--stroke engine oil
mixed at 50:1 ratio.
S Unleaded gasoline is recommended to re-
duce the contamination of the air for the
sake of your health and the environment.
S This hi--performance air cooled 2--stroke
engine requires the use of minimum 89
octane [R+M] /2 (mid--grade or premium)
clean gasoline. Gasoline may contain a
maximum of 10% Ethanol (grain alcohol)
or up to 15% MTBE (Methyl tertiary--butyl
ether). Gasoline containing Methanol
(Wood Alcohol) is NOT approved.
IMPOR TA NT! If the octane rating of the
mid-grade gasoline in your area is lower
than 89 octane use premium unleaded
gasoline. The majority of all 2--s troke
engine manufacturers in the USA and
Canada recommend using gasoline with 89
octane or higher.
CAUTI ON! Gasoline with an octane rating
lower than 89 will greatly increase the en-
gines operating temperature. Low octane
gasoline will cause detonation (knock)
resulting in piston seizures and major inter-
nal engine components damage.
Poor quality gasolines or oils may damage
sealing rings, fuel lines or fuel tank of the
engine.
IMPOR TA NT! Failures caused by operating
engines on gasoline with octane rating low-
er than 89 are not covered by the RedMax
2--s troke engine warranty.
CAUTI ON! 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, de-
terioration 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
S Use only RedMax “Max Life” synthetic
blend premium air--cooled 2--stroke en-
gine oil or oil certified to ISO--L--EGD
(ISO/CD 1378) standard and one that is
JASO--FD registered. RedMax air--cooled
“Max Life” synthetic blend premium
2--stroke engine oil and ISO--L--EGD
(ISO/CD 1378) AND JASO--FD oils are
fully compatible with gasoline’s containing
10% Ethanol. RedMax air--cooled “Max
Life” synthetic blend premium 2--stroke
engine oil and ISO--L --EGD (ISO/CD
1378) 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.
S If the oil is registered with JASO, the
JASO Logo with FD and registration num-
ber will be displayed on the container.
The highest JASO rating is “FD”, which
equals the ISO--L--EGD rating. Lower rat-
ings are “FC”, “FB”, and “F A”.
