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. 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.
3a)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.
3b) Do not smoke while handling fuel or
while operating the chain saw.
4. 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.
5. Never start cutting until you have a clear
work area, secure footing, and planned
retreat path from the falling tree.
6. 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.
7. Keep all parts of your body away from
the saw chain when the engine is
running.
8. Before you start the engine, make sure
the saw chain is not contacting anything.
9. 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.
10. 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.
11. 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).
12. Always shut off the engine before setting
it down.
13. 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.
14.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.
15. 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.

6. Fuel and Chain oil
FUEL
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.
RECOMMENDED MIXING RATIO
GASOLINE 32 : OIL 1
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.
The fuel is highly flammable. Do not smoke or
bring any flame or sparks near fuel.
HOW TO MIX FUEL
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 again for
at least one minute.
5. Put a clear indication on the outside of the
container to avoid mixing up with gasoline or
other containers.
FOR YOUR ENGINE LIFE, AVOID;
1. FUEL WITH NO OIL(RAW GASOLINE) – It will
cause severe damage to the engine inner 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 or WATER

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

F19
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.
