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 water­cooling 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.

As lot details of quality assurance, read the
description in the section Limited Warranty
carefully. Moreover, normal wear and
change in product with no functional
influence are not covered by the warranty.

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. (OP7)

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

■ REFILLING TRIMMING LINE (MA1)

1. For replacement line, use a diameter of .095in
(2.4mm). The spool is capable for a line upto 20ft
(6m) on the 4” head. Avoid using a larger line as
it may cut down the trimming performance.

For safety reasons, do not use metalreinforced
line.

2. Pinch the slotted area on the both sides of the
spool housing to unhook the bottom cap.

3. Take out the spool and pull off the old line. Put
one end of new line through the spool holes and
pull it until the length is equal between each part
of the line.

4. Wind up the line in the correct direction as
indicated on the spool.

5. Hook each end of the line in the slot on the edge
of the spool, and then put the ends through the
eyelets on the housing. Make sure that the
spring and the washers are in place.

6. While holding the spool against the housing, pull
the line ends to release them from the slot.

7. Line up the slot on the bottom cap with the hook
on the housing, press the cap against the
housing until it clicks.

•Make sure that the engine has stopped and is
cool before performing any service to the
machine. Contact with moving cutting head
or hot muffler may result in a personal injury.

■ AIR FILTER

• The air filter, if clogged, will reduce the engine
performance. Check and clean the filter element
in warm, soapy water as required. Dry
completely before installing. If the element is
broken or shrunk, replace with a new one. (MA2)

(1) air filter

■ FUEL FILTER

• When the engine runs short of fuel supply, check
the fuel cap and the fuel filter for blockage.
(MA3)

(1) fuel filter

■ SPARK PLUG

• Starting failure and mis-firing are often caused
by a fouled spark plug. Clean the spark plug and
check that the plug gap is in the correct range.
For a replacement plug, use the correct type
specified by RedMax. (MA4)

• REPLACEMENT PLUG IS A NGK CMR7A.

• Note that using any spark plug other than those
designated may result in the engine failing to
operate properly or in the engine becoming
overheated and damaged.

• To install the spark plug, first turn the plug until it
is finger tight, then tighten it a quarter turn more
with a socket wrench.

WARNING

■ MUFFLER

• Inspect periodically, the muffler for loose
fasteners, any damage or corrosion. If any sign
of exhaust leakage is found, stop using the
machine and have it repaired immediately.

• Note that failing to do so may result in the
engine catching on fire.

■ SPARK ARRESTER

• The muffler is equipped with a spark arrester to
prevent red hot carbon from flying out of the
exhaust outlet. Periodically inspect and clean as
necessary with a wire brush. In the State of
California it is required by law (Section 4442 of
the California Public Resources Code) to equip a
spark arrester when a gas powered tool is used
in any forest covered, brush covered, or grass
covered unimproved land. (MA5)

(1) spark arrester

■ GEAR CASE (MA6)

• The reduction gears are lubricated by
multipurpose, lithium-based grease in the gear
case. Supply new grease every 25 hours of use
or more often depending on the job condition.

• Remove the cutter holders before installing new
grease to arrange for old grease to exit.

■ INTAKE AIR COOLING VENT

•Never touch the cylinder, muffler, or spark
plugs with your bare hands immediately after
stopping the engine. The engine can
become very hot when in operation, and
doing so could result in severe burns.

•When checking the machine to make sure
that it is okay before using it, check the area
around the muffler and remove any wood
chips or leaves which have attached

themselves to the brushcutter. Failing to do
so could cause the muffler to become
overheated, and that this in turn could cause
the engine to catch on fire. Always make
sure that the muffler is clean and free of
wood chips, leaves, and other waste before
use.

• Check the intake air cooling vent and the area
around the cylinder cooling fins after every 25
hours of use for blockage, and remove any
waste which has attached itself to the
brushcutter. Note that it is necessary to remove
the engine cover shown in (MA7) in order to be
able to view the upper part of the cylinder.

• If waste gets stuck and causes blockage around
the intake air cooling vent or between the
cylinder fins, it may cause the engine to
overheat, and that in turn may cause mechanical
failure on the part of the brushcutter. (MA7)

(1) cylinder
(2) intake air cooling vent (back)

■ PROCEDURES TO BE PERFORMED AFTER
EVERY 100 HOURS OF USE

1. Remove the muffler, insert a screwdriver into the
vent, and wipe away any carbon buildup. Wipe
away any carbon buildup on the muffler exhaust
vent and cylinder exhaust port at the same time.

2. Tighten all screws, bolts, and fittings.

3. Check to see if any oil or grease has worked its
way in between the clutch lining and drum, and if
it has wipe it away using oil-free, lead-free
gasoline.

speed is too low, or the blade cuts too deep into
weeds. Adjust the engine speed and cutting
depth according to the condition of object.

• If the grass or other object gets caught in the
blade, or if the unit starts to shake or vibrate,
turn off the engine and check the whole unit.
Change the blade if it has been damaged.

• Turn off the engine and make sure the blade has
completely stop before checking the blade, and
removing any object got caught in.

■ OPERATION

1. Check the bolt to fasten the blade and be sure
the bolt has no fault, and no abrasion.

2. Be sure that the blade and the holder have been
fastened according to instruction and the blade
turns smoothly without abnormal noise. (OPT7)

• The rotating parts fastened incorrectly may
cause serious accident to the operator.

• Make sure that the blade is not bent, warped,
cracked, broken or damaged.

• If you find any error to the blade, discard it
and change new one which is certified by
RedMax.

■ By using the shoulder strap, hang the unit on
your right side. Adjust the strap length so that
the cutting head may become parallel to the
ground.(OPT8)

Make sure to use shoulder strap and debris

■ CONTROLLING BLADE BOUNCE

• Kick out can cause serious personal injury.

Carefully study this section. It is important that

WARNING

OPT7

OPT8

WARNING

WARNING

WARNING

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.

• Check the blade and the fasteners for
looseness, cracking, or bending.

• Check the cutting edges and reform with a flat
file.

Point (OPT9) :

1. Keep the end corner sharp.

2. Round the root of the edge, using round file.

3. Do not use water when using a grinder.

• It is recommended that filing should be done by
professionals.

• Especially regarding filing the saw blade, Leave
it to the professionals.

■ TRANSPORTING THE UNIT

• When you finish cutting in one location and wish
to continue work in another spot, turn off the
engine, and lift up the unit and carry it paying
attention fo the blade.

• Never forget to place the protective cover over
the blades.

• When transporting the unit over long distances,
detach the blade fix the unit by ropes.
