GENERAL SAFETY RULES  
KICKBACK  
See Figures 1 - 2.  
ROTATIONAL  
KICKBACK  
n 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.

n Thefollowingprecautionsshouldbefollowedtomini-  
KICKBACK  
DANGER ZONE  
mize kickback:  
1. Always grip the saw firmly with both hands. Hold the  
saw firmly with both hands when the unit 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 maintain control of  
the saw if kickback occurs.  
Fig. 2  
2. 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.  
3. Always cut with the unit running at full speed. Fully  
squeeze the throttle trigger and maintain a steady  
cutting speed.  
4. Use replacement parts such as low kickback chain,  
SAFE-T-TIP® anti-kickbacknoseguards, chainbrakes  
andspecialguidebarsthatreducetherisksassociated  
with rotational kickback.  
Useonlythereplacementguidebarsandlowkickback  
chains specified by the manufacturer for the saw.  
PULL  
n With a basic understanding of kickback, you can reduce  
or eliminate the element of surprise. Sudden surprise  
contributes to accidents.  
n Keep proper footing and balance at all times.  
n Do not cut above shoulder height or overreach when cutting.  
n Keep the SAFE-T-TIP® anti-kickback nose guard properly  
mounted on the guide bar to prevent rotational kickback.  
n Follow the sharpening and maintenance instructions for  
the saw chain.  
n 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.

GENERAL SAFETY RULES  
UNDERSTANDING YOUR CHAIN SAW SAFETY  
DEVICES  
See Figure 4.  
IN THE CUTTING/WORK AREA  
n Do not operate a chain saw in a tree, on a ladder, or scaf-  
fold; this is extremely dangerous.  
®
n Keep ALL children, bystanders, visitors, and animals out  
of the work area while starting or cutting with the chain  
saw.  
SAFE-T-TIP Anti-Kickback Nose Guard  
The SAFE-T-TIP® prevents kickback from happening, be-  
cause it covers the tip of the bar where kickback is gener-  
ated. Never attempt any kind of cutting where the SAFE-T-  
TIP® would have to be removed from the bar tip.  
NOTE: The size of the work area depends on the job  
being performed as well as the size tree or work piece  
involved. For example, felling a tree requires a larger work  
area than making bucking cuts.  
LOW KICKBACK SAW CHAIN  
The rakers (depth gauges) ahead of each cutter can minimize  
the force of a kickback reaction by preventing the cutters  
from digging in too deeply at the kickback zone. Only use  
replacement chain that is equivalent to original chain or has  
been certified as low kickback chain per ANSI B175.1.  
n Neverstartcuttinguntilyouhaveaclearworkarea,secure  
footing, and a planned retreat path from the falling tree.  
Cluttered area invite injuries.  
n Do not expose the chain saw to rain.  
n Do not use the chain saw in damp or wet locations.  
Low kickback saw chain is chain that has met the kickback  
performance requirements of ANSI B175.1 - 1991 (Amer-  
ican National Standard for Power Tools - Gasoline-Powered  
Chain Saws-Safety Requirements) when tested on the rep-  
resentative sample of chain saws below 3.8 c.i.d. specified  
in ANSI B175.1 - 1991.  
n Do not use the chain saw near flammable liquids, gases,  
or in any type of explosive atmosphere.  
n 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 bal-  
ance.  
As saw chains are sharpened during their useful life, they  
lose some of the low kickback qualities and extra caution  
should be used.  
n When cutting a limb that is under tension, be alert for  
spring back so that you will not be struck when the ten-  
sion in the wood fibers is released.  
GUIDE BARS  
Generally, guide bars with small radius tips have somewhat  
lower kickback potentials.  
n Do not force the chain saw. The job can be performed  
better and safer at the rate for which it was intended.  
n Always use the right product for your application. The  
chain saw should be used for cutting wood only. Never  
use the chain saw to cut plastic, masonry or non-wood  
building materials.  
When making a replacement, be sure to order one of the  
Ryobi bars listed for the saw in this operator's manual. The  
proper size SAFE-T-TIP® nose guard comes installed on the  
bar. Use only guide bars that have a provision for mounting  
the SAFE-T-TIP®.  
n Do not use the chain saw for purposes not intended.  
n Store idle chain saw when not in use. Chain saw should  
be stored in a dry and high or locked area out of the reach  
of children. When storing chain saw, remove battery and  
placethescabbardonthebarandchainorstorethechain  
saw in a carry case.  
SAFE-T-TIP®  
n 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.

Allow the battery pack to remain in the charger for 15  
to 30 minutes. When the battery pack reaches normal  
voltage range, the red LED should come on. If the  
red LED does not come on after 30 minutes, this may  
indicate a defective battery pack and should be  
replaced.  
LED WILL BE ON TO INDICATE STATUS OF  
CHARGER AND BATTERY PACK:  
See Figure 6.  
nRed LED on = Fast charging mode.  
nGreen LED on = Fully charged and in maintenance charge  
mode.  
nGreen LED on = When battery pack is inserted into

nAfter normal usage, a minimum of 1 hour of charging time  
is required to fully recharge battery pack.  
nThe battery pack will become slightly warm to the  
touch while charging. This is normal and does not  
indicate a problem.  
nYellow and Green LEDs on = Deeply discharged or  
defective battery pack.  
nDo not place the charger and battery pack in an area of  
extreme heat or cold. They will work best at normal room  
temperature.  
nNo LED on = Defective charger or battery pack.

OPERATION  
CHARGING A HOT BATTERY PACK  
CHAIN OIL SYSTEM  
See Figure 8.  
When using the tool continuously, the batteries in the battery  
pack will become hot. You should let a hot battery pack cool  
down for approximately 30 minutes before attempting to  
recharge. When the battery pack becomes discharged and  
is hot, this will cause the green LED to come on instead of  
the red LED. After 30 minutes, reinsert the battery pack in  
the charger. If the green LED continues to remain on, return  
batterypacktoyournearestRyobiAuthorizedServiceCenter  
for checking or replacing.  
n Use Homelite Bar and Chain Oil. It is formulated to  
perform over a wide temperature range with no dilution  
required.  
NOTE: Do not use dirty, used or otherwise contaminated  
oils. Damage may occur to the bar or chain.  
n Carefully pour the bar and chain oil into the tank.  
n Check and fill the oil tank when battery is recharged, or  
as needed.  
NOTE: This situation only occurs when continuous use of  
the tool causes the batteries to become hot. It does not  
occur under normal circumstances. Refer to “CHARGING  
A COOL BATTERY PACK” for normal recharging of batter-  
ies. If the charger does not charge your battery pack under  
normal circumstances, return both the battery pack and  
charger to your nearest Ryobi Authorized Service Center  
for electrical check.  
n Depress the oil tank cap several times to pump the oil to  
the chain before starting the saw.  
n Depress the oil tank cap every 20-30 seconds while cut-  
ting to keep the chain lubricated.  
NOTE: It is normal for oil to seep from the saw when not  
in use. To prevent seepage, empty the oil tank after each  
use. When storing the unit for a long period of time (three  
months or longer) be sure the chain is lightly lubricated; this  
will prevent rust on the chain and bar sprocket.  
TO INSTALL BATTERY PACK  
See Figure 7.  
n Place the battery pack in your chain saw. Align raised  
rib on battery pack with groove in chain saw’s battery  
port.  
n Make sure the latches on each side of the battery pack  
snap in place and that battery pack is secured in chain  
saw before beginning operation.  
TO REMOVE BATTERY PACK  
See Figure 7.
