1. Safety Precautions  
Things to check before using your  
Things to check before starting up the  
power auger  
engine  
• Before beginning work, look around  
carefully to get a feel for the shape of the  
land, and whether or not there are any  
obstacles which might get in the way while  
working, and remove any obstacles which  
can be cleared away before beginning  
work.  
• Take a careful look around to make sure  
that no obstacles exist within a perimeter  
of 15 feet or less around the power auger  
before starting the engine.  
• The area within a perimeter of 45 feet of  
the person using the power auger should  
be considered a hazardous area into  
which no one should enter while the  
power auger 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 power auger within the work area so  
as to maintain a distance between each  
person sufficient to ensure safety.  
• The power auger is equipped with a  
centrifugal clutch mechanism which  
causes the drills to begin to rotate as soon  
as the engine is started by putting the  
throttle into the start position. When  
starting the engine, hold it firmly in place  
so as to ensure that nor the throttle may  
not 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 drills stop rotating  
when the throttle is moved fully back to its  
original position. If the drills 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 power auger 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 drills or with the  
joints by which the drills are attached to  
the power auger.  
Avoid noise problem  
NOTE  
Check and follow the local regulations as  
to sound level and hours of operations  
for power auger.  
• In general, operate power auger between  
8a.m.and 5p.m.on week days and 9a.m.to  
5p.m.weekends. Avoid using power auger  
late at night and/or early in the morning.

1. Safety Precautions  
Things to be careful about when using  
your power auger  
• 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 power auger, grip the  
handles of the power auger 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 drilling 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 drilling.  
• 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 drill during operation, always be sure  
to turn off the engine before removing the  
object.  
• When you finish drilling in one location  
and wish to continue work in another spot,  
turn off the engine before carrying it to the  
new location.  
• Never transport the power auger over  
rough roads over long distances without  
first removing all fuel from the fuel tank, as  
doing so might cause fuel to leak from the  
tank as a result of shocks absorbed 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.  
• 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.

• 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   
Download from Www.Somanuals.com. All Manuals Search And Download.  
2. 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.  
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  
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.

Toutes les pièces autres que celles mentionnées ci-dessus, deux (2) ans d’utilisation, 90 jours pour la location, à  
compter de la date d’achat initial. La société, par l’intermédiaire d’un distributeur RedMax, réparera ou remplacera  
toute(s) pièce(s), sans frais et au bénéfice de l’acheteur original, en prenant en charge les frais de pièces et/ou de  
main d’œuvre. Telles sont les limites de la garantie.  
Le coût du transport de l'unité jusqu'au revendeur RedMax et depuis celui-ci sera à la charge de l'acheteur.  
L'acheteur ne supportera pas le coût de main d'oeuvre du diagnostic qui amène à la conclusion qu'une pièce  
garantie est défectueuse, si ce diagnostic est effectué chez le revendeur RedMax.  
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  
la période de garantie. Toute pièce garantie arrivée à l’échéance de son premier remplacement prévu sera garantie  
jusqu’à celui-ci.  
Toute pièce de rechange équivalente en performance ou en durabilité peut être utilisée pour l’entretien hors-garantie  
ou les réparations hors-garantie, et ce sans réduire l’obligation de garantie incombant à la société.  
La société sera tenue responsable des dommages aux autres composants du moteur causés par la défaillance de  
pièce(s) garantie(s) en période de garantie.  
La garantie ne s'applique pas aux unités endommagées par suite de: négligence dans la mise en oeuvre des  
instructions spécifiées dans le manuel du propriétaire/de l'utilisateur en vue d’une utilisation et d’un entretien correct,  
fausse manœuvre accidentelle, modification, utilisation abusive, lubrification incorrecte, utilisation de pièces ou  
d’accessoires autres que ceux spécifiés par la société, ou autres causes hors du contrôle de la société.  
Cette garantie ne couvre pas les pièces remplacées en raison de leur usure normale ou de changements  
d’apparence sans effets.  
Il n'existe aucune autre garantie explicite.  
Les garanties implicites, y compris la valeur marchande et la valeur d’usage pour une utilisation particulière, sont  
limitées à deux (2) ans d’utilisation à compter de la date originale de livraison.  
Les responsabilités pour les dommage conséquents ou incidents sont exclues de toutes les garanties.  
Certaines provinces n'autorisant pas les limitations à la durée des garanties implicites, ou les exclusions ou  
limitations relatives aux dommages incidents ou conséquents, la limitation indiquée ci-dessus peut ne pas vous être  
applicable.  
Cette garantie vous donne des droits juridiques spécifiques, et vous pouvez également jouir d’autres droits variant  
d'une province à l'autre.
