5. For safe operation  
BEFORE STARTING THE ENGINE  
1. Make sure there is always good ventilation when  
operating the pruner. Fumes from engine  
exhaust can cause serious injury or death.  
Never run the engine indoors!  
2. 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.  
3. 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.  
4. Inspect the entire unit for loose fasteners and  
fuel leakage. Make sure that the cutting  
attachment is properly installed and securely  
fastened.  
5. Always use the shoulder strap. Adjust the strap  
for comfort before starting the engine. The strap  
should be adjusted to fit your body according as  
your working posture.  
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.

HANDLING FUEL  
1. The engine of the RedMax product is designed  
to run on a mixed fuel which contains highly  
flammable gasoline. Never store cans of fuel or  
refill the tank of the unit 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.  
2. Never smoke while operating the unit or refilling  
its fuel tank.  
3. When refilling the tank, always turn off the  
engine and allow it to cool down. Take a careful  
look around to make sure that there are no  
sparks or open flames anywhere nearby before  
refueling.  
4. Wipe spilled fuel completely using a dry rag if  
any fuel spillage occurs during refueling.  
5. After refueling, screw the fuel cap back tightly  
onto the fuel tank and then carry the unit to a  
spot 10 feet (3 m) or more away from where it  
was refueled before turning on the engine.  
TRANSPORTATION  
1. Never transport the pruner nor set it down with  
the engine running. An engine that's running  
could be accidently accelerated causing the  
chain to rotate.  
2. Make sure the scabbard is in place when  
transporting the pruner.  
3. When carrying by hand, the chain should be  
pointing backward.  
4. Never transport the product over rough roads  
over long distances by vehicle without removing

5. For safe operation  
KICKBACK AND PINCHING SAFETY  
PRECAUTIONS  
Beware of kickback!  
Kickback can occur whenever the tip of the guide  
bar touches an object while the saw is operating.  
Kickback may force the bar up and back toward the  
operator with lightning-like speed!  
Beware of pinching.  
Pinching the saw along the tip of the guide bar may  
force the bar back rapidly toward the operator.  
Pinching can occur whenever wood closes in  
around the moving chain.  
WARNING  
Both kickback and pinching may cause you to lose  
control of the pole pruner which could result in  
serious personal injury. Do not rely exclusively  
on the safety device built into the pruner! You  
must take several steps to keep your jobs free from  
accident or injury:  
1. Understand kickback and pinching! You can  
reduce or eliminate the element of surprise.  
Sudden surprises contributes to accidents.  
2. Keep a firm grip on the pole pruner with both  
hands whenever the engine is running. A firm  
grip will help you reduce the affects of kickback  
and pinching as well as maintain control of the  
machine.  
3. Make sure the area in which you are cutting is  
free from obstructions. Do not let the nose of the  
guide bar contact a log, branch, or any other  
obstructions which could be hit while you  
operation the pole pruner.  
4. Cut at high engine speeds.  
5. Follow the manufacturer's instructions for  
sharpening and maintaining the chain.  
6. Use only the replacement bar and chain or  
equivalent as specified by the manufacturer.

5. For safe operation  
WARNING  
• Make sure the chain and sprocket are correctly  
adjusted before operating the pruner (see page  
15,16 for adjustment procedures). Never attempt  
chain adjustment with the engine running!  
• Always make sure the cutting attachment is  
properly installed and firmly tightened before  
operation.  
• Never use a cracked or warped guide bar:  
replace it with a serviceable one and make sure  
it fits properly.  
• If a saw blade should bind fast in a cut, shut off  
the engine immediately. Push the branch or tree  
to ease the bind and free the blade.  
• Do not operate the pole pruner with the muffler  
removed.  
• When cutting a limb that is under tension, be  
alert for springback so that you will not be struck  
by the moving limb.  
• Always stop the engine immediately and check  
for damage if you strike a foreign object or if the  
machine becomes tangled. Do not operate with  
broken or damaged equipment.  
IMPORTANT  
• Do not make unauthorized modifications or  
substitutions to the guide bar or chain.  
• Never allow the engine to run at high RPM  
without a load. Doing so could damage the  
engine.  
• Keep the pruner as clean as possible. Keep it  
free of loose vegetation, mud, etc.

• 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  
17   
Download from Www.Somanuals.com. All Manuals Search And Download.  
7. Fuel and chain 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. In the case of storing the product for a  
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.  
NOTE  
6. Indicate the contents on outside of  
container for easy identification.  
As lot details of quality assurance, read the  
description in the section Limited Warranty  
carefully. Moreover, normal wear and

may not be covered by the warranty.  
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.  
CHAIN OIL  
Use motor oil SAE 10W-30 all year round, or  
SAE 30-40 in summer and SAE 20 in winter.  
WARNING  
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.  
NOTE  
FOR YOUR ENGINE LIFE, AVOID;  
1. FUEL WITH NO OIL(RAW GASOLINE) –  
It will cause severe damage to the internal  
engine parts very quickly.  
Do not use waste or regenerated oil that can  
cause damage to the oil pump.  
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.

8. Operation  
STOPPING ENGINE (OP4)  
1. Release the throttle lever and run the engine for  
a half minute.  
2. Shift the ignition switch to the STOP position.  
IMPORTANT  
• Except for an emergency, avoid stopping the  
engine while pulling the throttle lever.  
OP6  
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. (OP6)  
(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.

• REPLACEMENT PLUG IS A NGK CMR7A.  
IMPORTANT  
• 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.  
87~104 in-lbs  
TIGHTENING TORQUE:  
(9.8~11.8 N.m.)  
MUFFLER  
WARNING  
• 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. (MA13)

9. Maintenance  
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 pole saw. 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 pole saw.  
Note that it is necessary to remove the engine  
cover shown in (MA14) in order to be able to  
view the upper part of the cylinder.  
MA14  
IMPORTANT  
(1)  
• 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 pole saw. (MA14)  
(1) cylinder  
(2)  
(2) intake air cooling vent (back)  
PROCEDURES TO BE PERFORMED AFTER  
EVERY 100 HOURS OF USE  
MA15  
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.  
(MA15)  
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.

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.  
Toute pièce garantie dont le remplacement n'est pas prévu dans le cadre de l’entretien obligatoire, ou pour laquelle  
est seulement prévue une inspection périodique pour "remplacement ou réparation si nécessaire" sera garantie pour

jusqu’à celui-ci.
