■ 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 watercooling type) mixed oil.

7. Fuel
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.

■ CUTTING WORK (LINE HEAD USAGE)
1. Always wear eye protection such as safety
goggles. Never lean over the rotating cutting
head. Rocks or other debris could be thrown
into eyes and face and cause serious
personal injury.
2. Keep the debris guard in place at all times
when the unit is operated.
TRIMMING GRASS AND WEEDS
• Always remember that the TIP of the line does
cutting. You will achieve better results by not
crowding the line into the cutting area. Allow the
unit to trim at its own pace.
1. Hold the unit so the head is off the ground and is
tilted about 20 degrees toward the sweep
direction. (OP1)
2. You can avoid thrown debris by sweeping from
your left to the right.
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.

■ CONTROLLING BLADE BOUNCE
• Kick out can cause serious personal injury.
Carefully study this section. It is important that
you understand what causes kick out, how you
can reduce the chance of kick out and how you
can remain in control of the unit if kick out does
occur.
1. What causes kick out:
• Kick out can occur when the moving blade
contacts an object that it cannot cut. This contact
causes the blade to stop for an instant and then
suddenly move or ”bounce” away from the object
that was hit. The operator can lose control of the
unit and the blade can cause serious personal
injury to the operator or any person nearby if the
blade contacts any part of the body.

2. How you can reduce the chance of kick out:
a. Recognize that kick out can happen. By
understanding and knowing about bounce,
you can help eliminate the element of
surprise.
b. Cut fibrous weeds and grass only. Do not
let the blade contact materials it cannot cut
such as hard, woody vines and brush or
rocks, fences, metal, etc
c. Be extra prepared for bounce if you must cut
where you cannot see the blade making
contact such as in areas of dense growth.
d. Keep the blade sharp. A dull blade increase
the chance of bounce.
e. Avoid feeding the blade too rapidly. The blade
can bounce away from material being cut if
the blade is fed faster than its cutting
capability.
f. Cut only from your right to your left.
g. Keep your path of advance clear of material
that has been cut and other debris.
3. How you can maintain the best control:
a. Keep a good, firm grip on the unit with both
hands. A firm grip can help neutralize bounce.
Keep your right and left hands completely
around the respective handles.
b. Keep both feet spread apart in a comfortable
stance and yet braced for the possibility that
the unit could bounce. Do not overreach.
Keep firm footing and balance.

8. Operation (EX-LRT only)
This product is equipped with extremely sharp
blades, and when used improperly these blades
can be extremely dangerous, and improper
handling can cause accidents which may in
turn lead to serious injury or death. For this
reason, you should always be careful to follow
the following instructions when using your
trimmer.
• Never hold the trimmer in a way in which the
blades are pointed towards someone else.
• Never allow the blades to come into proximity
with your body while the engine of the trimmer
is in operation.
• Always be sure to turn off the engine before
changing the angle of the blades, removing
branches which have become stuck in the
blades, or at any other time when coming into
close proximity with the blades.
• Always wear work gloves made of leather or
some other sturdy material when using the
trimmer.
• Always place the blade cover provided with
the trimmer over the blades when not in use.
•Falling branches may fall onto the face or
into the eyes, resulting in injuries,
scratches, and cuts, and for this reason
you should always be sure to wear a
helmet and face protector when using your
trimmer.
The thickness of branches which may be cut
using this trimmer is limited to up to
approximately 3/16" (5mm). Never try to cut
branches thicker than this, as doing so may
result in damage to the trimmer.
■ ADJUSTING THE ANGLE OF THE CUTTING

■ CHECKING OIL SUPPLY
After starting the engine, run the chain at medium
speed and see if chain oil is scattered off as shown
in the figure. (OP1)
(1) Chain oil
The oil reservoir has a capacity sufficient to provide
about 40 minutes of cutting time (when set to
deliver the minimum flow rate, or about as long as
you'll get from a tank of fuel). Be sure to refill the oil
tank every time when refueling the saw.
■ ADJUSTING OIL FLOW RATE
Never fill the oil reservoir nor adjust the oiler
with the engine running.
An increase in bar oil flow rate will speed oil
consumption, requiring more frequent checks on
the oil reservoir. To ensure sufficient lubrication, It
may be necessary to check the oil level more
frequently than at fuel tank refills.
The guide bar and chain are lubricated
automatically by a pump that operates whenever
the chain rotates. The pump is set at the factory to
deliver a minimum flow rate, but it can be adjusted
in the field. A temporary increase in oil flow is often
desirable when cutting things like hardwood or
wood with a lot of pitch.
Adjust the pump as follows:
1. Stop the engine and make sure the stop switch
is in the OFF position.
2. Place the unit on its side with the oil reservoir
up. (OP2)

Screwing in the screw too tightly may make it
impossible for the blades to move. Conversely, not
screwing in the screw tightly enough may make the
blades of the trimmer feel dull and cause leaves
and branches to become caught in the blades of
the trimmer.
QUICK TIP
If the blades become so worn down that it is no
longer possible to eliminate the gap between them,
you should contact the authorized RedMax
servicing dealer from which you purchased your
RedMax® trimmer to have the blades resharpened
or replaced.
■ GEAR CASE
The reduction gears are lubricated by
