■ CUTTING WORK (LINE HEAD USAGE)
WARNING
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.

8. Operation
1. Hold the unit so the head is off the ground and is
tilted about 20 degrees toward the sweep
direction. (OP7)
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
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.

■ REFILLING TRIMMING LINE
MA1
1. For replacement line, use a diameter of .095
in(2.4mm). The spool is capable for a line upto
27ft(8m)on the 4” head, and 46ft(14m)on the 6”
head. Avoid using a larger line as it may cut
down the trimming performance.
WARNING
MA2
MA3
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. (MA1)
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. (MA2)
4. Wind up the line in the correct direction as
indicated on the spool. (MA3)
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. (MA4)
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.

WARNING
• 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.
MA5
■ 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. (MA5)

■ 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. (MA7)

machine and have it repaired immediately.
• Note that failing to do so may result in the
engine catching on fire.
MA8
■ 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. (MA8)

■ GEAR CASE (MA9)
• 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
WARNING
• 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
23

brushcutter. Note that it is necessary to remove
the engine cover shown in (MA10) in order to be
able to view the upper part of the cylinder.
MA10
(1)
IMPORTANT
• 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. (MA10)
(1) cylinder
(2)
(2) intake air cooling vent (back)
■ PROCEDURES TO BE PERFORMED AFTER
EVERY 100 HOURS OF USE
MA11
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.

10. Storage
• Aged fuel is one of major causes of engine
starting failure. Before storing the unit, empty the
fuel tank and run the engine until it uses all the
fuel left in the fuel line and the carburetor. Store
the unit indoor taking necessary measures for
rust prevention.

WARNING
■ CONTROLLING BLADE BOUNCE
• Kick out can cause serious personal injury.
Carefully study this section. It is important that
28

11. Optional blade usage
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.
