Gasoline requirements
S All 2--stroke RedMax products are pow-
ered 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 stan-
dard 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 (eq. carburation, ignition timing
and port timing) without addition of any
major hardware or the introduction of an
inert material during combustion.
S The RedMax/ZENOAH engines are regis-
tered 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.
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 max-
imum of 10% Ethanol (grain alcohol) or up
to 15% MTBE (Methyl tertiary--butyl
ether). Gasoline containing Methanol
(Wood Alcohol) is NOT approved.
S
NOTE: 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--stroke en-
gine manufacturers in the USA and Can-
ada recommend using gasoline with 89
octane or higher.
S Poor quality gasolines or oils may dam-
age sealing rings, fuel lines or fuel tank
of the engine.
S
NOTE: Failures caused by operating
engines on gasoline with octane rating
lower than 89 are not covered by the
RedMax 2--stroke engine warranty.
WARNING:
Alternative fuels
(not gasoline) 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 gaso-
line engines. Use of alternative
fuels will cause major engine per-
formance and durability problems
such as: improper clutch engage-
ments, overheating, vapor lock,
power loss, lubrication deficiency,
deterioration of fuel lines, gaskets
and internal carburetor compo-
nents, etc. Alternative fuels cause
high moisture absorption into the
fuel/oil mixture leading to oil and
fuel separation.
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.
WARNING:
Gasoline with an
octane rating lower than 89 will
greatly increase the engines oper-
ating temperature. Low octane
gasoline will cause detonation
(knock) resulting in piston seizures
and major internal engine compo-
nents damage.
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.
