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.

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
– WARNING –
● 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.
A standard saw unit package contains the items as
shown. (SE1)
Open the box and install the guide bar and the saw
chain to the power unit as follows.
The saw chain has very sharp edges. Use thick,
protective gloves to avoid injury.
1. Loosen a nut and remove the chain cover.
2. Mount the guide bar and fit the saw chain
around the bar and the drive sprocket. Pay
attention to the correct direction of the saw
chain. (SE2)
3. Fit the chain tensioner nut into the lower hole of
the guide bar, then install the chain cover, and
fasten the mounting nut to finger tightness.
(SE3)
When installing the chain cover, be sure to fit the
hook completely at the rear end of the cover. (SE4)
4. While holding up the tip of the bar, adjust the
chain tension by turning the tensioner screw until
the tie straps just touch the bottom side of the
bar rail. (SE5)
5. Keep holding the guide bar up, tighten the
mounting nut firmly with the attached socket
wrench.
6. Rotate the saw chain by hand, wearing a
protective glove, to see if it turns smoothly
without noticeable gap between the tie straps
and the guide bar.
A new chain will expand its length in the beginning
of use. Check and readjust the tension frequently
as a loose chain can easily derail or cause rapid
wear of itself and the guide bar.

6. Fuel and chain oil
9
• 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)
RECOMMENDED MIXING RATIO
GASOLINE 50: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.
• Make sure to use gasoline with a minimum
octane number of 90 ROZ(USA/Canada : pump
octane min.87)
• 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
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
