BEFORE STARTING THE ENGINE  
1. The area within a perimeter of 50 feet (15m) of  
the person using the product should be  
considered a hazardous area into which no one  
should enter. If necessary yellow warning rope,  
warning signs 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 working so as to  
maintain a distance between each person  
sufficient to ensure safety.  
2. Check the condition of working area to avoid any  
accident by hitting hidden obstacles such as  
stumps, stones, cans, or broken grass.  
IMPORTANT  
Remove any obstacle before beginning work.  
3. Inspect the entire unit for loose fasteners and  
fuel leakage. Make sure that the cutting  
attachment is properly installed and securely  
fastened.  
4. Be sure the debris guard is firmly attached in  
place.  
5. Always use the shoulder strap. Adjust the strap  
for comfort before starting the engine. The strap  
should be adjusted so the left hand can  
comfortably hold the handlebar grip  
approximately waist high.  
STARTING THE ENGINE  
1. Keep bystanders and animals at least 50feet  
(15m) away from the operating point. If you are  
approached, immediately stop the engine.  
2. 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.

• 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.  
• 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.  
HOW TO MIX FUEL  
IMPORTANT  
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

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.  
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.  
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.

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.  
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.  
EX-BC  
OP1  
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.

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.

8. Operation (Optional blade usage EX-BC only)  
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.

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.

CHECKING OIL SUPPLY  
EX-PS  
OP1  
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  
NOTE  
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  
WARNING  
Never fill the oil reservoir nor adjust the oiler  
with the engine running.  
IMPORTANT  
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.  
EX-PS  
OP2  
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)

MA4  
• 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. (MA4)

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

brushcutter. Note that it is necessary to remove  
the engine cover shown in (MA5) in order to be  
able to view the upper part of the cylinder.

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. (MA6)

(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.

REFILLING TRIMMING LINE  
EX-BC  
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  
EX-BC  
MA2  
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)  
EX-BC  
MA3  
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.

• The reduction gears are lubricated by

9. Maintenance (EX-LRT only)  
BLADES (MA1)  
EX-LRT  
MA1  
• When refilling the tank or resting, it is often a  
good idea to use the time to oil the cutting  
blades.  
• If a gap exists between the upper and lower  
blades, follow the procedure below to adjust  
them so that they fit more closely together.  
1. Loosen lock nut (A) as shown in the diagram.  
2. Tighten screw (B) fully, and then turn one-  
third to one-half of a rotation backward.  
3. While holding onto the screw to keep it in  
position, tighten the lock nut.  
4. Check to make sure that the flat washer (C) is  
loose enough so that it may be turned by  
pressing on it with a finger.  
(1) Upper blade  
(2) Lower blade  
NOTE  
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.

L’acheteur ou propriétaire a pour responsabilité d’effectuer l’entretien obligatoire tel que défini par le fabricant dans le  
manuel du propriétaire/de l'utilisateur.
