GENERAL SAFETY RULES  
Keep handles dry, clean, and free of oil and  
WARNING:  
grease.  
Do not operate a chain saw that is damaged,  
improperly adjusted, or not completely and  
securely assembled. Chain should stop turning  
when the switch trigger is released. If the chain  
turns after the switch trigger has been released,  
have the unit serviced by your nearest Ryobi  
service dealer.  
Check for damaged parts. Any part or guard that  
has been damaged should be carefully checked  
to determine that it will operate properly and  
perform its intended function. Check for align-  
ment of moving parts, binding of moving parts,  
breakage of parts, mounting, and any other  
conditions that may affect its operation. A guard  
or other part that is damaged should be properly  
repaired or replaced by an authorized service  
dealer unless otherwise indicated elsewhere in  
this manual.  
All chain saw service, other than the items listed  
in the operation and maintenance sections,  
should be performed by your nearest Ryobi  
service dealer.  
Do not use in the rain, snow or wet conditions.  
Always maintain a proper stance. Do not over-  
reach.  
Do not adapt your powerhead to a bow guide  
or use it to power any attachments or devices  
not listed for the saw.  
Do not attempt to operate this unit until you  
have read thoroughly and understand com-  
pletely all instructions, safety information, etc.  
contained in this manual. Failure to comply can  
result in accidents involving fire, electric shock,  
or serious personal injury.  
READ ALL INSTRUcTIONS  
BASIc SAFETY PREcAUTIONS  
Do not operate a chain saw with one hand! Use  
a firm grip with thumbs and fingers encircling the  
chain saw handles. Serious injury to the operator,  
helpers, bystanders, or any combination of these  
persons may result from one-handed operation.  
A chain saw is intended for two-handed use.  
Always be aware of what you are doing when  
using the chain saw. Use common sense. Do  
not operate the chain saw when you are tired,  
ill, or under the influence of alcohol, drugs, or  
medication.  
Stay alert and pay attention to what you are  
doing. Use common sense when using this unit.  
Keep all parts of your body away from the saw  
chain when the unit is running.  
Always carry the chain saw by the front handle  
with the unit stopped and the guide bar and saw  
chain positioned to the rear. When transporting  
your chain saw, use the appropriate guide bar  
scabbard.  
Do not cut vines and/or small underbrush.  
Never let anyone use your chain saw who has  
not received adequate instructions in its proper  
use. This applies to rentals as well as privately  
owned saws.  
Before you start the unit, make sure the saw  
chain is not contacting any object.  
Stop the chain saw before setting it down. Do  
not leave the unit running unattended.  
To avoid accidental starting, never carry the unit  
with your finger on the switch trigger.  
Maintain the unit with care. Keep the cutting  
edge sharp and clean for best performance  
and to reduce the risk of injury. Follow instruc-  
tions for lubricating and changing accessories.  
Inspect the battery charger cord periodically,  
and if damaged, have it replaced or repaired by  
an authorized service dealer.  
SAFETY APPAREL  
Wear snug fitting clothing. Always wear heavy,  
long pants, long sleeves, overalls, jeans or  
chaps made of cut resistant material or ones  
that contain cut resistant inserts. Wear non-  
slip safety footwear. Wear non-slip heavy duty  
gloves to improve your grip and to protect your  
hands. Do not wear jewelry, short pants, san-  
dals, or go barefoot. Do not wear loose fitting  
clothing, which could be drawn into the motor  
or catch the chain or underbrush. Secure hair  
so it is above shoulder level.  
Wear eye protection which is marked to comply  
with ANSI Z87.1 as well as hearing and head  
protection when operating this equipment.

Follow the sharpening and maintenance instruc-  
WARNING: Kickback may occur when the  
moving chain contacts an object at the upper  
portion of the tip of the guide bar or when the  
wood closes in and pinches the saw chain in  
the cut. Contact at the upper portion of the tip  
of the guide bar can cause the chain to dig into  
the object and stop the chain for an instant.  
The result is a lightning fast, reverse reaction  
which kicks the guide bar up and back toward  
the operator. If the saw chain is pinched along  
the top of the guide bar, the guide bar can be  
driven rapidly back toward the operator. Either  
of these reactions can cause loss of saw control  
which can result in serious injury. Do not rely  
exclusively upon the safety devices built into  
the saw. As a chain saw user, you should take  
several steps to keep your cutting jobs free from  
accident or injury.  
tions for the saw chain.  
Push and Pull - This reaction force is always  
opposite to the direction the chain is moving  
where wood contact is made. Thus, the operator  
must be ready to control the PULL when cutting  
on the bottom edge of the bar, and PUSH when  
cutting along the top edge. See Figure 3.  
ROTATIONAL  
KICKBACK  
The following precautions should be followed  
to minimize kickback:  
1. Hold the saw firmly with both hands when  
the motor 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 chain saw handles. A firm grip  
together with a stiff left arm will help you  
maintaincontrolofthesawifkickbackoccurs.

DANGER ZONE  
2. Make sure that the area in which you are cut-  
ting 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.  
Fig. 2  
3. Always cut with the unit running at full speed.  
Fully squeeze the switch trigger and maintain  
a steady cutting speed.  
PULL  
4. Use replacement parts such as low kickback  
chain and special guide bars that reduce the  
risks associated with rotational kickback.  
Use only the replacement guide bars and low  
kickbackchainsspecifiedbythemanufacturer  
for the saw.  
PUSH  
With a basic understanding of kickback, you  
can reduce or eliminate the element of surprise.  
Sudden surprise contributes to accidents.

GENERAL SAFETY RULES  
Store idle chain saw when not in use. Chain saw  
IN THE cUTTING/WORK AREA  
should be stored in a dry and high or locked area  
out of the reach of children. When storing chain  
saw, remove battery and place the scabbard on  
the bar and chain or store the chain saw in a  
carry case.  
Do not operate a chain saw in a tree, on a ladder,  
rooftop or scaffold; this is extremely dangerous.  
Keep ALL children, bystanders, visitors, and  
animals out of the work area while starting or  
cutting with the chain saw.  
NOTE: The size of the work area depends on the  
jobbeingperformedaswellasthesizetreeorwork  
pieceinvolved. Forexample, fellingatreerequires  
a larger work area than making bucking cuts.  
Never start cutting until you have a clear work  
area, secure footing, and a planned retreat path  
from the falling tree. Cluttered area invite injuries.  
Do not expose the chain saw to rain.  
Donotusethechainsawindamporwetlocations.  
Do not use the chain saw near flammable liq-  
uids, gases, or in any type of explosive atmo-  
sphere.  
Use extreme caution when cutting small size  
brush and saplings, because slender mate-  
rial may catch the saw chain and be whipped  
toward you or pull you off balance.  
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.  
Remove the battery pack from the chain saw  
before cleaning, servicing, storing, removing  
material from the unit, changing accessories  
such as the bar and chain, or when not in use.

SAFETY DEVIcES  
LOW KIcKBAcK SAW cHAIN  
The rakers (depth gauges) ahead of each cutter

preventingthecuttersfromdiggingintoodeeplyat  
thekickbackzone.Onlyusereplacementchainthat  
is equivalent to original chain or has been certified  
as low kickback chain per ANSI B175.1.  
Low kickback saw chain is chain that has met  
the kickback performance requirements of ANSI  
B175.1 - 1991 (American National Standard for  
Power Tools - Gasoline-Powered Chain Saws-  
Safety Requirements) when tested on the repre-  
sentative sample of chain saws below 3.8 c.i.d.  
specified in ANSI B175.1 - 1991.  
Do not force the chain saw. The job can be per-  
formed better and safer at the rate for which it  
was intended.  
Always use the right product for your applica-  
tion. The chain saw should be used for cutting  
wood only. Never use the chain saw to cut plas-  
tic, masonry or non-wood building materials.  
Do not use the chain saw for purposes not  
intended.  
As saw chains are sharpened during their useful  
life, they lose some of the low kickback qualities  
and extra caution should be used.  
GUIDE BARS  
Generally, guide bars with small radius tips have  
somewhat lower kickback potentials.  
When making a replacement, be sure to order one  
of the Ryobi bars listed for the saw in this opera-  
tor’s manual.

SPEcIFIc SAFETY RULES  
cordless product in the presence of open flame.  
BATTERY SAFETY  
An exploded battery pack can propel debris and  
chemicals. If exposed, flush with water imme-  
diately.  
Battery operated units do not have to be plugged  
into an electrical outlet; therefore, they are  
always in operating condition. Be aware of pos-  
sible hazards even when unit is not operating.  
Do not charge unit in a damp or wet location.  
Following this rule will reduce the risk of electric  
shock.  
Remove the battery pack from the chain saw  
before cleaning, servicing, storing, removing  
material from the unit, changing accessories  
such as the bar and chain, or when not in use.  
For best results, your battery unit should be  
charged in a location where the temperature  
is more than 50°F but less than 100°F. Do not  
store outside or in vehicles.  
A battery pack must be recharged only with the  
specified charger for the battery pack. A charger  
that may be suitable for one type of battery pack  
may create a risk of fire when used with another  
battery pack. Use battery pack only with charger  
listed.  
Under extreme usage or temperature condi-  
tions, battery pack leakage may occur. If liquid  
comes in contact with your skin, wash imme-  
diately with soap and water. If liquid gets into  
your eyes, flush them with clean water for at  
least 10 minutes, then seek immediate medical  
attention.  
For use with 18V nickel-cadmium and 18 V  
lithium-ion battery packs, see tool/appliance/  
battery pack/charger correlation supplement  
987000-432.  
Do not dispose of batteries in a fire. The cell  
may explode. Batteries should be recycled, con-  
sult your local waste authority for information  
regarding available recycling and/or disposal  
options.  
To reduce the risk of explosion and possible  
injury, Do not place battery units or their batteries  
near fire or heat.  
Do not open or mutilate the battery pack.  
Released electrolyte is corrosive and may cause  
damage to the eyes or skin. It may be toxic if  
swallowed.  
When battery pack is not in use, keep it away  
from other metal objects like: paper clips, coins,  
keys, nails, screws, or other small metal objects  
that can make a connection from one terminal  
to another. Shorting the battery pack terminals  
together may cause sparks, burns, or a fire.  
Do not crush, drop or damage battery pack. Do  
not use a battery pack or charger that has been  
dropped or received a sharp blow. A damaged  
battery is subject to explosion. Properly dispose  
of a dropped or damaged battery immediately.  
Save these instructions. Refer to them frequently  
and use them to instruct others who may use  
this tool. If you loan someone this tool, loan  
them these instructions also.  
Batteries can explode in the presence of a  
source of ignition, such as a pilot light. To reduce  
the risk of serious personal injury, never use any
