US-9CHT220/CHT220LUSlines or fuel tank of the engine.• Failures caused by operating engines on gasoline with octanerating 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 gasolineand are NOT approved for use in RedMax 2-stroke gasolineengines. Use of alternative fuels will cause major engineperformance and durability problems such as: improperclutch engagements, overheating, vapor lock, power loss,lubrication deficiency, deterioration of fuel lines, gasketsand internal carburetor components, etc... Alternative fuelscause high moisture absorption into the fuel/oil mixtureleading 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 twostroke engine oil and ISO-L-EGD (ISO/CD1378) AND JASO-FDoils are fully compatible with gasoline's containing 10% Ethanol.RedMax Air-Cooled "Max Life", Synthetic blend Premium twostroke engine oil and ISO-L-EGD (ISO/CD1378) AND JASO-FDoils are Universal and should be mixed at 50:1 ratio for all 2stroke air cooled engines sold in the past regardless of mixingratios specified in those manuals.• If the oil is registered with JASO, the JASO Logo with FD andregistration number will be displayed on the container. Thehighest JASO rating is "FD", which equals the ISO-L-EGDrating. Lower ratings are "FC", "FB", and "FA".• Engine problems due to inadequate lubrication caused byfailure to use ISO-L-EGD certified and JASO FD registered oilsuch as "MaxLife", RedMax Synthetic blend Premium 2-strokeoil WILL VOID THE REDMAX TWO-STROKE ENGINEWARRANTY.• Do not use NMMA (National Marine ManufacturersAssociation), BIA (Boating Industry Association), and TCW (twocycle water cooled) oils designed for MoPeds or Outboard,water cooled Marine Engines. Do not use API (AmericanPetroleum Institute), TC (Two Cycle) labeled oils. The API-TCWARNINGWARNINGNOTE6. FuelFUEL• Gasoline is very flammable. Avoid smoking or bringing anyflame or sparks near fuel. Make sure to stop the engine andallow it cool before refueling the unit. Select outdoor bareground for fueling and move at least 10 ft (3 m) away fromthe fueling point before starting the engine.■ GASOLINE REQUIREMENTS• All 2-Stroke RedMax Products are powered by RedMaxProfessional-Commercial Duty, Hi-Performance, Hi-RPM, AirCooled 2-Stroke engines.RedMax – Hi-Performance 2-stroke engines produce higher HPoutputs as compared to standard Home Owner Duty or LightCommercial Duty production engines offered by mostmanufacturers.• Exhaust emission are controlled by the fundamental engineparameters and components (eq., carburation, ignition timingand port timing) without addition of any major hardware or theintroduction of an inert material during combustion.• The RedMax Engines are registered and certified with CARB(California Air Resources Board) and EPA (EnvironmentalProtection Agency) to operate on CLEAN Mid-grade 89 octaneor Premium, unleaded (lead-free) gasoline and RedMax Air-Cooled "Max Life", Synthetic blend Premium two-stroke engineoil mixed at 50:1 ratio.• Unleaded gasoline is recommended to reduce thecontamination of the air for the sake of your health and theenvironment.• This Hi-Performance Air Cooled 2-stroke Engine requires theuse 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 NOTapproved.• IF octane rating of the Mid Grade gasoline in your area is lowerthan 89 Octane use Premium Unleaded Gasoline. The majorityof all 2-stroke engine manufacturers in the USA and Canadarecommend using gasoline with 89 Octane or higher.• Gasoline with an octane rating lower than 89 will greatlyincrease the engines operating temperature. Low octanegasoline will cause detonation (knock) resulting in pistonseizures and major internal engine components damage.• Poor quality gasolines or oils may damage sealing rings, fuelWARNINGNOTEWARNING[ R+M ]2
