4. For safe operation

1. Never operate a chain saw when you are
fatigued, ill, or upset, or under the
influence of medication that may make
you drowsy, or if you are under the
influence of alcohol or drugs.

2. Use safety footwear, snug fitting clothing
and eye, hearing and head protection
devices.

3. Select flat and bare ground for fueling.

4. Always use caution when handling fuel.
Wipe up all spills and then move the
chain saw at least ten(10) feet(three(3)
m) from the fueling point before starting
the engine.

4a) Eliminate all sources of sparks or

flame (ie. smoking, open flames, or
work that can cause sparks) in the
areas where fuel is mixed, poured, or
stored.

4b) Do not smoke while handling fuel or

while operating the chain saw.

5. Do not allow other persons to be near
the chain saw when starting the engine
or cutting a wood. Keep bystanders and
animals out of the work area. Children,
pets, and bystanders should be a
minimum of thirty(30) feet away when
you start or operate the chain saw.

6. Never start cutting until you have a clear
work area, secure footing, and planned
retreat path from the falling tree.

7. Always hold the chain saw firmly with
both hands when the engine is running.
Use a firm grip with thumb and fingers
encircling the chain saw handles.

8. Keep all parts of your body away from
the saw chain when the engine is
running.

9. Before you start the engine, make sure
the saw chain is not contacting anything.

10. Always carry the chain saw with the
engine stopped, the guide bar and saw
chain to the rear, and the muffler away
from your body.

11. Always inspect the chain saw before
each use for worn, Ioose, or changed
parts. Never operate a chain saw that is
damaged, improperly adjusted, or is not
completely and securely assembled. Be
sure that the saw chain stops moving
when the throttle control trigger is
released.

12. All chain saw service, other than the
items listed in the Operator’s Manual,
should be performed by competent chain
saw service personnel. (e.g., if improper
tools are used to remove the flywheel, or
if an improper tool is used to hold the
flywheel in order to remove the clutch,
structural damage to the flywheel could
occur which could subsequently cause
the flywheel to disintegrate).

13. Always shut off the engine before setting
it down.

14. Use extreme caution when cutting small
size brush and saplings because slender
material may catch the saw chain and be
whipped toward you or pull you off
balance.

15. When cutting a limb that is under
tension, be alert for spring back so that
you will not be struck when the tension in
the wood fibers is released.

16. Keep the handles dry, clean and free of
oil or fuel mixture.

 7 

4. For safe operation

16. Operate the chain saw only in well
ventilated areas. Never start or run the
engine inside a closed room or building.
Exhaust fumes contain dangerous
carbon monoxide.

17. Do not operate a chain saw in a tree
unless specially trained to do so.

18. Guard against kickback. Kickback is the
upward motion of the guide bar which
occurs when the saw chain at the nose
of the guide bar contacts an object.
Kickback can lead to dangerous loss of
control of the chain saw.

19. When transporting your chain saw, make
sure the appropriate guide bar scabbard
is in place.

20. This chain saw is equipped with a spark
arrester built-in muffler. Periodically
check the arrester to keep it in good
order.

KICKBACK SAFETY PRECAUTIONS FOR

CHAIN SAW USERS

● Kickback may occur when the nose or tip of the guide bar touches an object, or when the
wood closes in and pinches the saw chain in the cut. Tip contact in some cases may
cause a lightning fast reverse reaction, kicking the guide bar up and back towards the
operator. Pinching the saw chain along the top of the guide bar may push the guide bar
rapidly back towards the operator. Either of these reactions may cause you to lose
control of the saw which could result in serious personal injury.

● Do not rely exclusively on the safety devices built into your saw. As a chain saw user you
should take several steps to keep cutting jobs free from accident or injury.

(1) With a basic understanding of kickback you can reduce or eliminate the element of

surprise. Sudden surprise contributes to accidents.

(2) Keep a good grip on the saw with both hands, the right hand on the rear handle, and

the left hand on the front handle, when the engine is running. Use a firm grip with
thumbs and fingers encircling the chain saw handles. A firm grip will help you reduce
kickback and maintain control of the saw. Don’t let go.

(3) Make certain that the area in which you’re cutting is free from obstructions. Do not let

the nose of the guide bar contact a log, branch, or any other obstruction which could

be hit while you are operating the saw.
(4) Cut at high engine speeds.
(5) Do not overreach or cut above shoulder height.
(6) Follow manufacturers sharpening and maintenance instructions for saw chain.
(7) Only use replacement bars and chains specified by the manufacturer or the

equivalent.

■ RECOMMENDED MIXING RATIO

GASOLINE 50:OIL 1
(when using ZENOAH genuine oil)

• 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.

■ HOW TO MIX FUEL

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

IMPORTANT

• Gasoline is very flammable. Avoid
smoking or bringing any flame or
sparks near fuel. Make sure to stop the
engine and allow it cool before
refueling the unit. Select outdoor bare
ground for fueling and move at least
3m (10ft) away from the fueling point
before starting 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 water­cooling type) mixed oil.

■ CHAIN OIL

Use motor oil SAE 10W-30 all year round, or
SAE 30-40 in summer and SAE 20 in winter.

Do not use waste or regenerated oil that can
cause damage to the oil pump.

NOTE

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. 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.

■ 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.

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.

5. In the case of storing the product for a

WARNING

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.

■ CHAIN BRAKE

This machine is equipped with an automatic brake
to stop saw chain rotation upon occurrence of
kickback while in saw cutting operation. The brake
is automatically operated by inertial force which
acts on the weight fitted inside the front guard.
This brake can also be operated manually with the
front guard turned down to the guide bar.
To release brake, pull up the front guard toward the
front handle till "click" sound is heard. (F15)

Be sure to confirm brake operation on the daily
inspection.

How to confirm:

1) Turn off the engine.

2) Holding the chain saw horizontally, release your
hand from the front handle, hit the tip of the
guide bar to a stump or a piece of wood, and
confirm brake operation. Operating level varies
by bar size. (F16)

In case the brake is not effective, ask our dealer
inspection and repairing.
The engine, If being kept rotated at high speed with
the brake engaged, heats the clutch, causing a
trouble.
When the brake is operated while in operation,
immediately release your fingers from the throttle
lever and stop the engine.

Carburetor anti-freeze mechanism

Operating the chain saws in temperatures of 0–5°C
at times of high humidity may result in ice forming
within the carburetor, and this in turn may cause
the output power of the engine to be reduced or for
the engine to fail to operate smoothly.
This product has accordingly been designed with a
ventilation hatch on the right side of the surface of
the cylinder cover to allow warm air to be supplied
to the engine and to thereby prevent icing from
occurring.
Under normal circumstances the product should be
used in normal operating mode, i.e., in the mode to
which it is set at the time of shipment. However
when the possibility exists that icing may occur, the
unit should be set to operate in anti-freeze mode
before use.(F18)

(1) Normal operating mode
(2) Anti-freeze mode
(3) Cylinder cover
(4) ‘Sun shine’ mark
(5) ‘Snow’ mark

Continuing to use the product in anti-freeze
mode even when temperatures have risen and
returned to normal may result in the engine
failing to start properly or in the engine failing
to operate at its normal speed, and for this
reason you should always be sure to return the
unit to normal operating mode if there is no
danger of icing occurring.

• Before proceeding to your job, read "For
Safe Operation" section It is recommended
to first practice sawing easy logs. This also
helps you get accustomed to your unit.

•Always follow the safety regulations. The
chain saw must only be used for cutting
wood. It is forbidden to cut other types of
material. Vibrations and kickback vary with
different materials and the requirements of
the safety regulations would not be
respected. Do not use the chain saw as a
lever for lifting, moving or splitting objects.
Do not lock it over fixed stands. It is
forbidden to hitch tools or applications to the
P.t.o. that are not specified by the
manufacturer.

•It is not necessary to force the saw into the
cut. Apply only light pressure while running
the engine at full throttle.

• When the saw chain is caught in the cut, do
not attempt to pull it out by force, but use a
wedge or a lever to open the way.

■ GUARD AGAINST KICKBACK (F21)

• This saw is equipped with a chain brake that will
stop the chain in the event of kickback if
operating properly. You must check the chain
brake operation before each usage by running
the saw at full the throttle for I -2 seconds and
pushing the front hand guard forward. The chain
should stop immediately with the engine at full
speed. If the chain is slow to stop or does not
stop, replace the brake band and clutch drum
before use.

• It is extremely important that the chain brake be
checked for proper operation before each use
and that the chain be sharp in order to maintain
the kickback safety level of this saw. Removal of
the safety devices, inadequate maintenance, or
incorrect replacement of the bar or chain may
increase the risk ot serious personal injury due
to kickback.

■ SAW CHAIN

It is very important for smooth and safe
operation to keep the cutters always sharp.

Your cutters need to be sharpened when:

• Sawdust becomes powder-like.

• You need extra force to saw in.

• The cut way does not go straight.

• Vibration increases.

• Fuel consumption increases.

Cutter setting standards:

Be sure to wear safety gloves.

Before filing:

• Make sure the saw chain is held securely.

• Make sure the engine is stopped.

• Use a round file of proper size for your chain.

Chain type: 91VG

File size: 5/32 in (4.0mm)

Place your file on the cutter and push straight
forward. Keep the file position as illustrated. (F36)

After every cutter has been set, check the depth
gauge and file it to the proper level as illustrated.
(F37)

Be sure to round off the front edge to reduce
the chance of kickback or tie-strap breakage.

(1) Appropriate gauge checker
(2) Make the shoulder round
(3) Depth gauge standard

■ GUIDE BAR

• Reverse the bar occasionally to prevent partial
wear.

• The bar rail should always be a square. Check
for wear of the bar rail. Apply a ruler to the bar
and the outside of a cutter. If a gap is observed
between them, the rail is normal. Otherwise, the
bar rail is worn. Such a bar needs to be
corrected or replaced. (F39)

Toutes les pièces autres que celles mentionnées ci-dessus, deux (2) ans d’utilisation domestique, 1 an

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 domestique, un (1) an d’utilisation commerciale et quatre-vingt-dix (90) jours pour

la location, 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.
