G3300
1. For safe operation
WARNING
This chainsaw has been especially designed for tree
maintenance and should therefore only be used by
trained operators when working on trees.
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.
Use the vibration-proof glove.
3. Keep the saw chain sharp and the
saw, including the AV system, well
maintained. A dull chain will increase
cutting time, and pressing a dull
chain through wood will increase the
vibrations transmitted to your hands.
A saw with loose components or with
damaged or worn AV buffers will also
tend to have higher vibration levels.
4. Always use caution when handling
fuel. Wipe up all spills and then move
the chain saw at least 3 m from the
fueling point before starting the engine.
5. Eliminate all sources of sparks or
flame (i.e. smoking, open flames, or
work that can cause sparks) in the
areas where fuel is mixed, poured,
or stored.
6. Do not smoke while handling fuel or
while operating the chain saw.
7. Do not allow other persons to be near
the chain saw when starting or cutting. Keep bystanders and animals
out of the work area. Children, pets
and bystanders should be a minimum
of 10 m away when you start or operate the chain saw.
8. Never start cutting until you have a
clear work area, secure footing, and
a planned retreat path from the falling tree.
9. 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.
GB-4
10. Keep all parts of your body away from
the saw chain when the engine is running.
11. Before you start the engine, make
sure the saw chain is not contacting
anything.
12. 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.
13. Always inspect the chain saw before
each use for worn, Ioose, or damaged 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.
14. All chain saw service, other than the
items listed in the Owner’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.)
15. Always shut off the engine before
setting it down.
16. 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.
17. 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.
18. Never cut in high wind, bad weather,
when visibility is poor or in very high
or low temperatures. Always check
the tree for dead branches which
could fall during the felling operation.
19. Keep the handles dry, clean and free
of oil or fuel mixture.
G3300
20. Operate the chain saw only in well
ventilated areas. Never start or run
the engine inside a closed room or
building and potentially explosive atmosphere. Exhaust fumes contain
dangerous carbon monoxide.
21. Do not operate the chain saw in a tree
unless specially trained to do so.
22. 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.
23. When transporting your chain saw,
make sure the appropriate guide bar
scabbard is in place.
24. Never touch the cover, guide bar, saw
chain or nut with bare hands while
the engine is in operation or immediately after shutting down the engine.
Doing so could result in serious burns
because of high temperature.

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 Iose 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.
(3) Make certain that the area in which
you are 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 the manufacturer’s sharpening
and maintenance instructions for the
saw chain.
(7) Only use replacement bars and
chains specified by the manufacturer
or the equivalent.
WORSE EFFECTS OF VIBRATION
If you continue to use high-vibration tools these
symptoms will probably get worse, for example:
• the numbness in your hands could become permanent and you won’t be able to feel things at all;
• you will have difficulty picking up small objects such
as screws or nails;
• the vibration white finger could happen more frequently and affect more of your fingers.
FOR PROTECTING YOUR BODY FROM VIBRATION
Please observe the following matter, in order to protect the health of your body.
1. Always use the right tool for each job (to do the job
more quickly and expose you to less hand-arm vibration).
2. Check tools before using them to make sure they
have been properly maintained and repaired to avoid
increased vibration caused by faults or general wear.
3. Make sure cutting tools are kept sharp so that they
remain efficient.
4. Reduce the amount of time you use a tool in one go,
by doing other jobs in between.
5. Avoid gripping or forcing a tool or workpiece more
than you have to.
6. Store tools so that they do not have very cold handles
when next used.
7. Encourage good blood circulation by:
• keeping warm and dry (when necessary, wear
gloves, a hat, waterproofs and use heating pads if
available);
• giving up or cutting down on smoking because
smoking reduces blood flow; and massaging and
exercising your fingers
DISPOSAL
• When you dispose of the machine, do not disassemble the machine.
• When you dispose of the machine, fuel, chain oil,
be sure to follow your local regulations.

4. Fuel and Chain Oil
■ FUEL
• 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 3 m (10 ft) away from the
fueling point before starting the engine.
• The Zenoah engines are lubricated by oil specially
formulated for air-cooled 2-cycle gasoline engine use.
If Zenoah 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.
■ 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 89RON (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
•
4. Pour in the rest of gasoline and agitate 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 10 feet (3 meters) 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 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.
Note: As for 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.
■ CHAIN OIL
Use motor oil SAE #10W-30 all year round or SAE
#30 ~ #40 in summer and SAE #20 in winter.
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.
GB-8
Note: Do not use wasted or regenerated oil that can cause damage
to the oil pump.

GB-9
G3300
The carburetor on your unit has been factory adjusted,
but may require fine tuning due to a change in operating conditions.
Before adjusting the carburetor, make sure that the provided air/fuel filters are clean and fresh and the fuel properly mixed.
When adjusting, take the following steps:
Note: Be sure to adjust the carburetor with the bar chain attached.
1. H and L needles are restricted within the number of
turn as shown below.
H needle : -1/4
L needle : -1/4
2. Start the engine and allow it to warm up in low speed
for a few minutes.
3. Turn the idle adjusting screw (T) counterclockwise
so that the saw chain does not turn. If the idling
speed is too slow, turn the screw clockwise.
4. Make a test cut and adjust the H needle for best
cutting power, not for maximum speed.
In case the brake is not effective, ask our dealer for
inspection and repairs.
If the engine keeps rotating at high speed with the brake
engaged, the clutch will overheat causing trouble.
When the brake engages during operation, immediately
release the throttle lever to stop the engine.
■ STOPPING THE ENGINE
1. Release the throttle lever to allow the engine to idle
for a few minutes.
2. Set the switch to the “O” (STOP) position.
(1)
(1) Switch
■ CHAIN BRAKE
This machine is equipped with an automatic brake to
stop saw chain rotation upon occurrence of kickback
during saw cutting. 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 the brake, pull up the front guard toward the
front handle till a “click” sound is heard.
(3)
■ CARBURETOR ANTI-FREEZE MECHANISM
Operating 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 insulator 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 the 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 the anti-freeze mode before use.
Stop the engine, remove the cylinder cover and install
the grommet A to the appropriate position of the mode.
See ■ Maintenance part for how to remove the cylinder
cover.

[Caution]
Be sure to confirm brake operation during 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.

6. Sawing
•
Before proceeding to your job,
read the section “For Safe
Operation”. 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 PTO other than those
specified by the manufacturer.
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.
■ FELLING A TREE
Felling direction
Notch cut
•
•
•
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.
If the guide bar and saw chain becomes
caught in wood while operating it, stop the
engine.
Do not pry the handle with excessive force.
Use a wedge to remove the chain instead.
■ GUARD AGAINST KICKBACK
Felling cut
1. Decide the felling direction considering the wind,
lean of the tree, location of heavy branches, ease of
completing the task after felling and other factors.
2. While clearing the area around the tree, arrange a
good foothold and retreat path.
3. Make a notch cut one-third of the way into the tree
on the felling side.
4. Make a felling cut from the opposite side of the notch
and at a level slightly higher than the bottom of the
notch.
When you fell a tree, be sure to warn neighboring workers of the danger.
Bucking and Limbing
• Always ensure your foothold. Do not stand
on the log.
• Be alert to the rolling over of a cut log. Especially when working on a slope, stand
on the uphill side of the log.
• Follow the instructions in “For Safe Operation” to avoid kickback of the saw.
•
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 -
Before starting work, check the direction of bending
force inside the log to be cut. Always finish cutting from
the opposite side of the bending direction to prevent
the guide bar from being caught in the cut.

•
Do not use an unstable foothold or ladder.
Do not overreach.
Do not cut above shoulder height.
Always use both your hands to hold the
saw.
7. Maintenance
Before cleaning, the inspecting or repairing
the unit, make sure that engine has stopped
and is cool. Disconnect the spark plug to prevent accidental starting.
2. Guide bar
When the guide bar is dismounted, remove sawdust in
the bar groove and the oiling port.

8. Maintenance of Saw Chain and Guide Bar
■ Saw Chain
It is very important for smooth and safe operation to always keep the cutters sharp.
The cutters need to be sharpened when:
• Sawdust becomes powder-like.
• You need extra force to saw in.
• The cut path does not go straight.
• Vibration increases.
• Fuel consumption increases.
Be sure to round off the front edge to reduce
the chance of kickback or tie-strap breakage.
Make sure every cutter has the same length and edge
angles as illustrated.

Cutter setting standards:
Filing angle
Be sure to wear safety gloves.
Side plate angle
Before filing:
• Make sure the saw chain is held securely.
• Make sure the engine is stopped.
• Use a round file of proper size for the chain.
Chain type:
91VG
File size:
5/32 in (4.0 mm)
Place the file on the cutter and push straight forward.
Keep the file position as illustrated.

■ Guide Bar
• Reverse the bar occasionally to prevent partial wear.
• The bar rail should always be square. Check for wear
of the bar rail. Apply a ruler to the bar and the out-
side 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.

No gap
After each cutter has been filed, check the depth gauge
and file it to the proper level as illustrated.
