7. Fuel
■RECOMMENDED MIXING RATIO
GASOLINE 50:OIL 1
•Exhaust emission are controlled by the
fundamental engine parameters and
components(eq., carburation, ignition
timing and port timing) without
addition of any major hardware or the
introduction of an inert material during
combustion.
•These engines are certified to operate on
unleaded gasoline.
•Make sure to use gasoline with a
minimum octane number of 89 RON
(USA/Canada: 87AL)
•If you use a gasoline of a lower octane
value than prescribed, there is a danger
that the engine temperature may rise and
an engine problem such as piston seizing
may consequently occur.
•Unleaded gasoline is recommended to
reduce the contamination of the air for the
sake of your health and the environment.
•Poor quality gasolines or oils may damage
sealing rings, fuel lines or fuel tank of the
engine.
■HOW TO MIX FUEL
Pay attention to agitation.
1. Measure out the quantities of gasoline
and oil to be mixed.
2. Put some of the gasoline into a clean,
approved fuel container.
3. Pour in all of the oil and agitate well.
4. Pour In the rest of gasoline and agitate
IMPORTANT
•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
3m (10ft) away from the fueling point
before starting the engine.
•The RedMax engines are lubricated by oil
specially formulated for air-cooled 2-cycle
gasoline engine use. If RedMax oil is not
available, use an anti-oxidant added
quality oil expressly labeled for air-cooled
2-cycle engine use. (JASO FC GRADE
OIL or ISO EGC GRADE)
•Do not use BIA or TCW (2-stroke water-
cooling type) mixed oil.

again for at least one minute. As some
oils may be difficult to agitate depending
on oil ingredients, sufficient agitation is
necessary for the engine to last long. Be
careful that, if the agitation is insufficient,
there is an increased danger of early
piston seizing due to abnormally lean
mixture.
5. Put a clear indication on the outside of the
container to avoid mixing up with gasoline
or other containers.
6. Indicate the contents on outside of
container for easy identification.
■FUELING THE UNIT
1. Untwist and remove the fuel cap. Rest the
cap on a dustless place.
2. Put fuel into the fuel tank to 80% of the full
capacity.
3. Fasten the fuel cap securely and wipe up
any fuel spillage around the unit.
1. Select bare ground for fueling.
2. Move at least 10feet (3meters) away from
the fueling point before starting the
engine.
3. Stop the engine before refueling the unit.
At that time, be sure to sufficiently agitate
the mixed gasoline in the container.
FOR YOUR ENGINE LIFE, AVOID;
1. FUEL WITH NO OIL(RAW GASOLINE) –
It will cause severe damage to the internal
engine parts very quickly.
2. GASOHOL – It can cause deterioration of
rubber and/or plastic parts and disruption
of engine lubrication.
3. OIL FOR 4-CYCLE ENGINE USE – It can
cause spark plug fouling, exhaust port
blocking, or piston ring sticking.
4. Mixed fuels which have been left
unused for a period of one month or
more may clog the carburetor and result
in the engine failing to operate properly.
5. In the case of storing the product for a
WARNING
long period of time, clean the fuel tank
after rendering it empty. Next, activate the
engine and empty the carburetor of the
composite fuel.
6. In the case of scrapping the used mixed
oil container, scrap it only at an authorized
repository site.

3. Use a slow, deliberate action to cut heavy
growth. The rate of cutting motion will depend on
the material being cut. Heavy growth will require
slower action than will light growth.
4. Never swing the unit so hard as you are in
danger of losing your balance or control of the
unit.
5. Try to control the cutting motion with the hip
rather than placing the full workload on the arm
and hands.
6. Take precautions to avoid wire, grass and dead,
dry, long-stem weeds from wrapping around the
head shaft. Such materials can stall the head
and cause the clutch to slip, resulting in damage
to the clutch system if repeated frequently.
ADJUSTING THE LINE LENGTH
•Your brushcutters is equipped with a semi- auto
type nylon line head that allows the operator to
advance the line without stopping the engine.
When the line becomes short, lightly tap the
head on the ground while running the engine at
full throttle.
•Each time the head is bumped, the line advance
about 1 inch(25.4 mm). For better effect, tap the
head on bear ground or hard soil. Avoid
bumping in thick, tall grass as the engine may
stall by overload.
