Fuel
Note! The machine is equipped with a
2--stroke engine and must always be run us- ing a mixture of gasoline and two-stroke en- gine 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 inaccura- cies can drastically affect the ratio of the mixture.
WARNING: Always ensure there is adequate ventilation when han- dling fuel.
Gasoline
SUse good quality unleaded gasoline.
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
SAll 2--stroke RedMax products are pow- ered by 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.
SExhaust 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.
SThe RedMax engines are registered and cer- tified 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 2--stroke engine oil
mixed at 50:1 ratio.
SUnleaded gasoline is recommended to re- duce the contamination of the air for the
sake of your health and the environment.
SThis 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.

IMPORTANT! 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 engine manufacturers in the USA and Canada recommend using gasoline with 89 octane or higher.
CAUTION! 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.
IMPORTANT! Failures caused by operating engines on gasoline with octane rating low- er than 89 are not covered by the RedMax 2--stroke engine warranty.
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, 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
SUse 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--FDregistered. RedMax air--cooled “Max Life” synthetic blend premium
2--stroke engine oil and ISO--L--EGD(ISO/CD 1378) AND JASO--FDoils 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--FDoils 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.
SIf 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 “FA”.
