• 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  
9   
 
Fuel  
again for at least one minute. As some  
long period of time, clean the fuel tank  
after rendering it empty. Next, activate the  
engine and empty the carburetor of the  
composite fuel.  
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.  
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.  
NOTE  
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.  
Also, be careful that, if the usage in the  
instruction manual is not observed as to the  
mixed gasoline, etc. described therein, it  
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.  
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.  
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.

WARNING  
Air Filter  
• Make sure that the engine has stopped  
and is cool before performing any  
service to the blower. Contact with  
rotating blower fan or hot muffler may  
result in a personal injury.  
AIR CLEANER  
FUEL FILTER  
• Check the air cleaner every 25 hours of  
use or more frequently if used under dusty  
conditions. A clogged air filter may  
increase fuel consumption while cutting  
down the engine power. Never operate  
the blower without the air filter or with a  
deformed filter element because unfiltered  
dusty air will quickly ruin the engine.  
• A clogged fuel filter may cause poor  
acceleration of the engine. Check  
periodically to see if the filter is clogged  
with dirt. The filter can be taken out of the  
fueling port using a small wire hook.  
Disconnect the filter assembly from the  
fuel pipe and unhook the retainer to  
disassemble it. Clean the components  
with gasoline.  
CLEANING AIR FILTER:  
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.  
12   
 
Maintenance  
SPARK PLUG  
the muffler may get loose during operation  
which may result in engine catching on  
fire.  
• The spark plug may gather carbon  
deposits on its firing end with reasonable  
use. Remove and inspect the spark plug  
every 25 hours and clean the electrodes  
as necessary with a wire brush. The spark  
gap should be adjusted to .024~.028 in.  
(0.6~0.7mm).  
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.  
• Plug manufacturers recommend replacing  
the plug twice a year to avoid unexpected  
plug failure in a job.  
REPLACEMENT PLUG IS A 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.  
AIR INLET SCREEN  
IMPORTANT  
• 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.  
• Blowing air is taken in from the air inlet  
screen. When air flow has dropped down  
during operation, stop the engine and  
inspect the air inlet screen for blocking by  
obstacles.  
• Note that failure to remove any such  
obstacles may result in the engine  
becoming overheated and damaged.  
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 blower  
and have it repaired immediately.  
WARNING  
• Never use the blower without the  
screen at the air intake of the blower.  
• Note that failing to do so may result in  
the engine catching on fire.  
IMPORTANT  
• Before starting operation, always make  
sure to check if the muffler is properly held  
by two bolts to the cylinder. (Fastening  
Torque : 70~110kg·cm)  
• Even if one bolt out of two bolts is loose,  
13   
 
Maintenance  
PROCEDURES TO BE PERFORMED AFTER  
EVERY 50 HOURS OF USE  
• 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.  
• Tighten all screws, bolts, and fittings.  
Storage  
BEFORE STORING THE BLOWER:  
1. Drain a fuel tank and push the primer bulb until it  
becomes empty of fuel.  
2. Remove the spark plug and drop a spoonful of  
2-cycle oil into the cylider. Crank the engine  
several time and install the spark plug.

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

jusqu’à celui-ci.

limitations relatives aux dommages incidents ou conséquents, la limitation indiquée ci-dessus peut ne pas vous être
