FUEL HANDLING

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.

Gasoline

Use good quality unleaded gasoline.

WARNING:

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

All 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.

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.

The 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.

Unleaded gasoline is recommended to re-

duce 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 [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

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.

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 “FA”.
