Safety Precautions  
Work gear and clothing  
Warnings considering handling of fuel  
• When using your brushcutter, always be  
sure to wear strong, durable, work clothing;  
shirts should be long-sleeved shirts and  
pants should be full-length pants reaching  
down to the ankles.  
• The engine of the RedMax® brushcutter is  
designed to run on a mixed fuel which  
contains highly flammable gasoline. This  
fuel is highly flammable and you should  
never store cans of fuel or refill the tank of  
the brushcutter in any place where there is  
a boiler, stove, wood fire, electrical sparks,  
welding sparks, or any other source of heat  
or fire which might ignite the fuel.  
• Always be sure to wear helmet and face  
protector when using your brushcutter.  
• When using your brushcutter, always be  
sure to wear thick work gloves to protect  
your hands and non-slip-sole work boots to  
prevent you from slipping. Never use your  
brushcutter when wearing pants with loose  
cuffs, when wearing sandals, or when  
barefoot.  
• Smoking while operating the brushcutter or  
refilling its fuel tank is extremely  
dangerous. Always be sure to keep lit  
cigarettes away from the brushcutter at all  
times.  
• When using your brushcutter for an  
extended period of time, you should wear  
ear protectors to protect yourself from loss  
of hearing from overexposure to high levels  
of sound.  
• When refilling the tank, always turn off the  
engine first and take a careful look around  
to make sure that there are no sparks or  
open flames anywhere nearby before  
refueling.  
• If any fuel spillage occurs during refueling,  
always be sure to use a dry rag to wipe any  
fuel which has been spilled onto the  
brushcutter before turning the engine back  
on again.  
• After refueling, screw the fuel cap back  
tightly onto the fuel tank and then carry the  
brushcutter to a spot 10 feet (3m) or more  
away from where it was refueled before  
turning on the engine.

Safety Precautions  
Things to check before using your  
Things to check before starting up the  
brushcutter  
engine  
• Before beginning work, look around  
carefully to get a feel for the shape of the  
land, grass to be trimmed, and whether or  
not there are any obstacles which might get  
in the way while working, and remove any  
obstacles before beginning work.  
• Take a careful look around to make sure  
that no obstacles exist within a perimeter of  
15 feet (5m) or less around the brushcutter  
before starting the engine.  
• The area within a perimeter of 50 feet  
(15m) of the person using the brushcutter  
should be considered a hazardous area  
into which no one should enter while the  
brushcutter is in use, and when necessary  
yellow warning rope, warning signs, or  
some other form of warnings should be  
placed around the perimeter of the area.  
When work is to be performed  
simultaneously by two or more persons,  
care should also be taken to constantly  
look around or otherwise check for the  
presence and locations of other people  
using brushcutters within the work area so  
as to maintain a distance between each  
person sufficient to ensure safety.  
The RedMax brushcutter is equipped with a  
centrifugal clutch mechanism which causes  
the cutting blades to begin to rotate as  
soon as the engine is started by putting the  
throttle into the start position. When starting  
the engine, place the body of the  
brushcutter onto the ground in a flat clear  
area and hold it firmly in place so as to  
ensure that neither the blades nor the  
throttle come into contact with any  
obstacles when the engine starts up.  
Never place the throttle into the high speed  
position when starting the engine.  
After starting up the engine, check to make  
sure that the blades stop rotating when the  
throttle is moved fully back to its original  
position. If the blades continue to rotate  
even after the throttle has been moved fully  
back, turn off the engine and take the unit  
to your authorized Red Max servicing  
dealer for repair.  
• Before beginning work, each component of  
the brushcutter should be checked to make  
sure that it is in proper working order and to  
make sure that there are no loose screws  
or bolts, fuel leaks, ruptures, dents, or any  
other problems which might interfere with  
safe operation. Be especially careful at this  
time to check that there is nothing wrong  
with the blades or with the joints by which  
the blades are attached to the brushcutter.  
AVOID NOISE PROBLEM  
NOTE  
Check and follow the local regulations  
as to sound level and hours of  
operations for brushcutter.  
• In general, operate brushcutters between  
8a.m.and 5p.m.on week days and 9a.m.to  
5p.m.weekends. Avoid using brushcutter  
late at night and/or early in the morning.

Safety Precautions  
Things to be careful about when using  
your brushcutter  
• Never touch the muffler, spark plug, or  
other metallic parts of the engine while the  
engine is in operation or immediately after  
shutting down the engine. These metallic  
parts reach high temperatures during  
operation and doing so could result in  
serious burns.  
• When using your brushcutter, grip the  
handles of the brushcutter firmly with both  
hands, place your feet slightly apart  
(slightly further apart than the width of your  
shoulders) so that your weight is distributed  
evenly across both legs, and always be  
sure to maintain a steady, even posture  
while working.  
• Maintain the speed of the engine at the  
level required to perform cutting work, and  
never raise the speed of the engine above  
the level necessary.  
• Always be sure never to allow other  
persons to come within the work area while  
cutting.  
• Be especially careful not to slip if it is  
raining or if rain has just stopped, as the  
ground is likely to be slippery at such times.  
• If the grass or other object gets caught in  
the blade during operation, always be sure  
to turn off the engine before removing the  
object.  
• When you finish cutting in one location and  
wish to continue work in another spot, turn  
off the engine, place the protective cover  
over the blades, and turn the brushcutter  
so that the blade face away from your body  
before carrying it to the new location.  
• Never transport the brushcutter over rough  
roads over long distances without removing  
all fuel from the fuel tank. If doing so, fuel  
might leak from the tank during transport.  
• Guard against hazardous situations at all  
times. Warn adults to keep pets and  
children away from the area. Establish a  
safe method for gaining your attention  
during operation. Be careful if you are  
approached.  
If someone calls out or otherwise interrupts  
you while working, always be sure to turn  
off the engine before turning around.  
• Keep operation area clear of all persons,  
particularly small children and pets. Injury  
may result from flying debris.  
• Never touch the spark plug or plug cord  
while the engine is in operation. Doing so  
may result in being subjected to an  
electrical shock.

Operation  
NOTE  
WARNING  
• The product is equipped with a  
centrifugal clutch mechanism, so the  
cutting attachment begins to rotate as  
soon as the engine is started by putting  
the throttle into the start position. When  
starting the engine, place the product  
onto the ground in a flat clear area and  
hold it firmly in place so as to ensure  
that neither the cutting part nor the  
throttle come into contact with any  
obstacle when the engine starts.  
• Except for an emergency, avoid stopping  
the engine while pulling the throttle lever.  
ADJUSTING IDLING SPEED  
1. When the engine tends stop frequently at  
idling mode, turn the adjusting screw  
clockwise.  
2. When the cutting head keeps rotating after  
releasing the trigger, turn the adjusting  
screw counter-clockwise.  
NOTE  
NOTE  
Avoid pulling the rope to its end or returning  
it by releasing the knob. Such actions can  
cause starter failures.  
• Warm up the engine before adjusting the  
idling speed.  
6.When the engine has started, move the  
choke lever gradually downward to open  
the choke.  
LINE HEAD USAGE  
WARNING  
7.Allow the engine to warm up for a half  
minute before starting operation.  
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 attached in  
place at all times when the unit is  
operated.  
NOTE  
1.When restarting the engine immediately  
after stopping it, leave the choke open.  
2.Overchoking can make the engine hard to  
start due to excess fuel. When the engine  
failed to start after several attempts, open  
the choke and repeat pulling the rope, or  
remove the spark plug and dry it.  
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.  
STOPPING ENGINE  
1. Release the throttle lever and run the  
engine for a half minute.  
2. Shift the ignition switch to the STOP  
position.  
1. Hold the unit so the head is off the ground  
and is tilted about 20 degrees toward the  
sweep direction.  
13 

Operation  
2. Use full throttle when cutting.  
3. You can avoid thrown debris by sweeping  
from your left to the right.  
4. 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.  
5. Never swing the unit so hard as you are in  
danger of losing your balance or control of  
the unit.  
6. Try to control the cutting motion with the  
hip rather than placing the full workload on  
the arm and hands.  
7. 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.

• The product is equipped with a centrifugal  
clutch mechanism, so the cutting attachment  
begins to rotate as soon as the engine is  
started by putting the throttle into the start  
position. When starting the engine, place the  
product onto the ground in a flat clear area  
and hold it firmly in place so as to ensure that  
neither the cutting part nor the throttle come  
into contact with any obstacle when the  
engine starts.  
CUTTING METHOD

WARNING  
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.

Optional blade usage  
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.  
OPT9  
MAINTENANCE  
BLADE  
• Check the blade and the fasteners for  
looseness, cracking, or bending.  
• Check the cutting edges and reform with a flat  
file.  
Point (OPT8) :  
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.  
IMPORTANT  
• 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.

Maintenance  
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.  
WARNING  
• Always be sure to stop the engine before  
inspecting the brushcutter for problems  
or performing maintenance.  
• Never alter the brushcutter or take the  
engine apart.  
• When replacing parts, always be sure to  
use only RedMax products or products  
which have been certified by RedMax for  
use with the RedMax brushcutter.  
• Things to check before using  
brushcutter  
REFILLING TRIMMING LINE  
1. For replacement line, use a diameter of  
.095 in(2.4 mm). The spool is capable for a  
line upto 27 ft(8 m)on the 4” head, and 46  
ft(14m)on the 6” head. Avoid using a larger  
line as it may cut down the trimming  
performance. For safety reasons, do not  
use metalreinforced line.  
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.  
2. Pinch the slotted area on the both sides of  
the spool housing to unhook the bottom  
cap.  
WARNING  
• Make sure that the engine has stopped  
and is cool before performing any  
service to the brushcutter. 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. Monthly 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.  
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 as indicated  
on the spool.

Maintenance  
FUEL FILTER  
• Note that failing to do so may result in  
the engine catching on fire.  
When the engine runs short of fuel supply,  
check the fuel cap and the fuel filter for  
blockage.  
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.  
SPARK PLUG  
• Starting failure and mis-firing are often  
caused by a fouled spark plug. Periodically  
clean the spark plug and check that the  
spark gap is in the correct range. For a  
replacement plug, use the correct type  
specified by RedMax(See SPECIFI-  
CATIONS on the page 23).  
GEAR CASE  
• The reduction gears are lubricated by  
multipurpose, lithium-based grease in the  
gear case. Supply new grease every 50  
hours of use or more often depending on  
the job condition.  
• REPLACEMENT PLUG IS A CHAMPION  
RCJ6Y OR THE EQUIVALENT, SUCH AS  
BOSCH WSR8E OR NGK BPMR7A.  
IMPORTANT  
Note that using any spark plugs 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.  
MUFFLER  
WARNING  
• Inspect periodically, the muffler for loose  
fasteners, any damage or corrosion. If any  
sign of exhaust leakage is found, do not  
use the brushcutter and have it repaired  
immediately.

Maintenance  
INTAKE AIR COOLING VENT  
IMPORTANT  
WARNING  
• 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.  
• 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 brushcutter 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. Note that failing to do so  
could cause the muffler to become  
overheated, and that this in turn could  
cause the brushcutter 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 plug guard shown in Figure  
20 in order to be able to view the upper  
part of the cylinder.  
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 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.  
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.
