Thank you for buying a Ryobi chainsaw.
Your new chainsaw has been engineered and manufactured
to Ryobiʼs high standard for dependability, ease of
operation, and operator safety. Properly cared for, it will
give you years of rugged, trouble-free performance.
WARNING
To reduce the risk of injury, the user must read and
understand the operatorʼs manual.
IMPORTANT
Servicing requires extreme care and knowledge
and should be performed only by a qualified service
technician. When servicing use only identical
Ryobi replacement parts. For safe operation, read
and understand all instructions before using the
chainsaw. Follow all safety instructions. Failure to
follow all safety instructions listed below may result
in serious personal injury.
WARNING
Carefully read through this entire operatorʼs manual
before using your new saw. Pay close attention to the
Safety Rules and all Safety Alert Symbols including
Danger, Warning, and Caution. These safety rules
are for your safety and to prevent possible serious
injury. If you use your saw properly and only for what
it is intended,
you will enjoy years of safe, reliable service.
WARNING
Look for this symbol to point out important safety
precautions. It means attention!!! Your safety is
involved.
WARNING
The operation of any tool can result in foreign objects
being thrown into your eyes which may result in
severe eye damage. Before beginning tool operation,
always wear safety goggles or safety glasses with
side shields and a full face shield when needed. We
recommend Wide Vision Safety Mask for use over
spectacles or standard safety glasses with side
shields.
Always wear eye protection.
READ ALL INSTRUCTIONS.
GENERAL SAFETY RULES
WARNING
The warnings, labels, and instructions found in
this section of the operatorʼs manual are for your
safety. Failure to follow all instructions may result in
serious personal injury. Safe operation of this tool
requires that you read and understand this operatorʼs
manual and all labels affixed to the tool. Safety is a
combination of using common sense, staying alert,
and knowing how your saw works.
■KNOW YOUR TOOL. Read the operatorʼs manual
carefully. Learn the sawʼs applications and limitations
as well as the specific potential hazards related to this
tool.
■CHAINSAWS are designed for cutting wood only.
■KICK-BACK MAY OCCUR WHEN THE NOSE OF
THE GUIDE BAR touches an object or when the wood
closes in and pinches the saw chain in the cut. The
nose of guide bar contact in some cases may cause
a lightning-fast reverse reaction kicking the guide bar
up and back toward the operator. Pinching the saw
chain along the top of the guide bar may push the
guide bar rapidly back toward 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 upon the safety devices built into
your saw. As a chainsaw user, you should take several
steps to keep your cutting jobs free from accident or
injury.
1. With a basic understanding of kick-back, you can
reduce or eliminate the element of surprise. Sudden
surprise contributes to accidents.
2. Keep a good firm grip on the saw with both hands
when the engine is running. Place your right hand on
the rear handle and your left hand on the front handle
with your thumbs and fingers encircling the chainsaw
handles. A firm grip together with a stiff left arm will help
you maintain control of the saw if kick-back occurs.
3. Make sure 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, fence, or any other
obstruction that could be hit while you are operating
the saw.
4. Cut at high engine speeds. Always cut with the engine
running at full speed. Fully squeeze the throttle trigger
and maintain a steady cutting speed.
5. Do not overreach or cut above chest height.
6. Follow the manufacturerʼs sharpening and
maintenance instructions for the saw chain.

GENERAL SAFETY RULES
7. Use only replacement bars and chains specified by
the manufacturer or the equivalent.
■DO NOT OPERATE A CHAINSAW WITH ONE
HAND. Serious injury to the operator, helpers, and/or
bystanders may result from one-handed operation. A
chainsaw is intended for two-handed use.
■DO NOT OPERATE A CHAINSAW WHEN YOU ARE
FATIGUED. Never operate a chainsaw when you are
tired or under the influence of medication, drugs, or
alcohol.
■USE SAFETY FOOTWEAR. Wear snug-fitting
clothing, protective gloves, and eye, hearing, and head
protection devices.
■DO NOT STAND ON ANY UNSTABLE SURFACE
while using your chainsaw: that includes ladders,
scaffolds, trees, etc.
■USE CAUTION WHEN HANDLING FUEL. Move the
chainsaw at least 50 feet (15 m) from the refuelling
point before starting the engine.
■DO NOT ALLOW OTHER PERSONS to be near the
chainsaw when starting or cutting with the chainsaw.
Keep bystanders and animals out of the work area.
■DO NOT START CUTTING until you have a clear work
area, secure footing, and a planned retreat path from
the falling tree.
■KEEP ALL PARTS OF YOUR BODY away from the
saw chain when the engine is running.
■ALWAYS CARRY THE CHAINSAW WITH THE
ENGINE STOPPED AND THE BRAKE ENGAGED, the
guide bar and saw chain to the rear, and the silencer
away from your body. When transporting the chainsaw,
use the appropriate guide bar scabbard.
■DO NOT OPERATE A CHAINSAW THAT IS
DAMAGED, improperly adjusted, or not completely and
securely assembled. Be sure that the saw chain stops
moving when the throttle control trigger is released.
■TURN OFF THE ENGINE before putting the chainsaw
down. DO NOT leave the engine running unattended.
As an additional safety precaution, apply the chain
brake before putting down the saw.
■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.
■WHEN CUTTING A LIMB under tension, be alert for
spring-back so that you will not be struck when the
tension in the wood fibres is released.
■KEEP THE HANDLES dry, clean, and free of oil or fuel
mixture.
■OPERATE THE CHAINSAW ONLY in well-ventilated
areas.
■DO NOT OPERATE A CHAINSAW IN A TREE unless
you have been specifically trained to do so.
■ALWAYS HAVE A FIRE EXTINGUISHER AVAILABLE
WHEN USING CHAIN SAW.
■FOLLOW THE SHARPENING and maintenance
instructions for the saw chain.
■USE ONLY THE REPLACEMENT GUIDE BARS and
low kick-back chains specified for your saw.
■DO NOT adapt your powerhead to a bow guide or use
it to power any attachments or devices not listed for
your saw.
■SAVE THESE INSTRUCTIONS. Refer to them
frequently and use to instruct other users. If you lend
someone this tool, lend them these instructions also.
SPECIFIC SAFETY RULES
WARNING
The warnings, labels, and instructions found in this
section of the operatorʼs manual are for your safety.
Failure to follow all instructions may result in serious
personal injury.
GENERAL PRECAUTIONS
■DO NOT CUT VINES and/or small undergrowth (less
than 76 mm (3 in.) in diameter).
■MUFFLER SURFACES ARE VERY HOT during and
after operation of the chainsaw; keep all body parts
away from the muffler. Serious burns may occur if
contact is made with the muffler.
■ALWAYS HOLD THE CHAINSAW WITH BOTH
HANDS when the engine is running. Use a firm grip with
thumbs and fingers encircling the chainsaw handles.
■NEVER LET ANYONE USE YOUR CHAINSAW who
has not received adequate instructions in its proper
use. This applies to rentals as well as privately owned
saws.
■BEFORE YOU START THE ENGINE, make sure the
saw chain is not contacting any object.
■OPERATE THE CHAINSAW only in well ventilated
areas.

SPECIFIC SAFETY RULES
PROPER CLOTHING FOR SAFETY
■Wear close-fitting clothing. Always wear heavy, long
trousers, boots, and gloves. Do not wear jewellery,
shorts, sandals, or go barefoot. Do not wear loose-
fitting clothing, which could be drawn into the engine or
catch the chain or undergrowth. Wear overalls, jeans,
or leggings made of cut-resistant material or ones that
contain cut-resistant inserts. Secure hair so that it is
above shoulder level.
■Wear non-slip safety footwear and heavy-duty gloves
to improve your grip and to protect your hands.
■Wear eye, hearing, and head protection when operating
this equipment.
REFUELLING (DO NOT SMOKE!)
■To reduce the risk of fire and burn injury, handle fuel
with care. It is highly flammable.
■Mix and store fuel in a container approved for petrol.
■Mix fuel outdoors where there are no sparks or
flames.
■Select bare ground, stop the engine, and allow it to cool
before refuelling.
■Loosen the fuel cap slowly to release pressure and to
keep fuel from escaping around the cap.
■Tighten the fuel cap securely after refuelling.
■Wipe spilled fuel from the unit. Move 15 m (50 ft.) away
from refuelling site before starting engine.
■Never attempt to burn off spilled fuel under any
circumstances.
BASIC PRECAUTIONS IN THE CUTTING/ WORK
AREA
■Do not operate a chainsaw in a tree.
■Do not cut from a ladder: this is extremely
dangerous.
■Keep bystanders and animals out of the work area. Do
not allow other persons to be nearby during starting or
cutting with the chainsaw.
NOTE: The size of the work area depends on the job
being performed as well as the size tree or workpiece
involved. For example, felling a tree requires a larger
work area than making other cuts, i.e. bucking cuts
etc.
PUSH AND PULL
The reaction force is always opposite to the direction the
chain is moving. Thus, the operator must be ready to control
the PULL when cutting on the bottom edge of the bar and
the PUSH when cutting along the top edge.
NOTE: Your chainsaw has been fully factory tested.
It is normal to find some slight oil residue on the saw.
MAINTENANCE PRECAUTIONS
Never operate a chainsaw 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. If the saw chain moves at
idling speed, the carburettor may need adjusting. Refer to
“Operation-Adjusting Idling Speed” later in this manual.
If the saw chain still moves at idling speed after adjustment
has been made, contact a Homelite service dealer for
adjustment and discontinue use until the repair is made.
WARNING
All chainsaw service, other than items in the
operatorʼs manual maintenance instructions, should
be performed by competent chainsaw service
personnel. If improper tools are used to remove
the flywheel or clutch, 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 burst and
serious injury could result.
KICK-BACK
Kick-back is a dangerous reaction that can lead to serious
injury. Do not rely only on the safety devices provided
with your saw. As a chainsaw user, you must take special
safety precautions to help keep your cutting jobs free from
accident or injury.
NOTE: Refer to “Operation” later in this manual for added
information on kick-back and how to avoid serious personal
injury.
SAVE THIS MANUAL FOR FUTURE REFERENCE.
