IMPORTANT SAFETY INSTRUCTIONS

WARNING:

Do not attempt to operate this unit until you have
read thoroughly and understand completely 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.

■ 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 trigger.

■ Maintain the unit with care. Keep the cutting edge
sharp and clean for best performance and to
reduce the risk of injury. Follow instructions for

lubricating and changing accessories. Inspect the
battery charger cord periodically, and if damaged,
have it replaced or repaired by an authorized
service dealer.

■ Keep handles dry, clean, and free of oil and grease.

■ Do not operate a chain saw that is damaged,

improperly adjusted, or not completely and securely
assembled. Chain should stop turning when the
trigger is released. If the chain turns after the
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 alignment 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 adapt your powerhead to a bow guide or

use it to power any attachments or devices not
listed for your saw.

■ Do not cut vines and/or small underbrush.

SAFETY APPAREL

■ Wear snug fitting clothing. Always wear heavy, long
pants, overalls, jeans or chaps made of cut resis­tant material or ones that contain cut resistant
inserts. Wear non-slip safety footwear. Wear non­slip heavy duty gloves to improve your grip and to
protect your hands. Do not wear jewelry, short
pants, sandals, 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.

IMPORTANT SAFETY INSTRUCTIONS

KICKBACK

See Figures 1 and 2.

■ 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 your
saw. As a chain saw user, you should take several
steps to keep your cutting jobs free from accident
or injury.

■ The following precautions should be followed
to minimize 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 the 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.

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-kickback nose guards,
chain brakes and special guide bars that reduce
the risks associated with rotational kickback.

Use only the replacement guide bars and low
kickback chains specified by the manufacturer
for your saw.

■ With a basic understanding of kickback, you can
reduce or eliminate the element of surprise. Sud­den surprise contributes to accidents.

■ Keep proper footing and balance at all times.

■ Do not cut above shoulder height or overreach

when cutting.

■ Keep the SAFE-T-TIP anti-kickback nose guard
properly mounted on the guide bar to prevent
rotational kickback.

■ Follow the sharpening and maintenance instruc­tions for the saw chain.

IMPORTANT SAFETY INSTRUCTIONS

■ 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.

IN THE CUTTING/WORK AREA

■ Do not operate a chain saw in a tree, on a ladder,
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
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.

■ 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.

■ Do not use the chain saw in damp or wet locations.

■ Do not use the chain saw near flammable liquids,

gases, or in any type of explosive atmosphere.

■ 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 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.

■ Do not force the chain saw. The job can be per­formed better and safer at the rate for which it was
intended.

■ 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.

■ Do not use the chain saw for purposes not in­tended.

■ 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 place the scabbard on the
bar and chain or store the chain saw in a carry
case.

■ 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.

IMPORTANT SAFETY INSTRUCTIONS

UNDERSTANDING YOUR CHAIN SAW
SAFETY DEVICES

See Figure 4.

SAFE-T-TIP® Anti-Kickback Nose Guard

The SAFE-T-TIP® prevents kickback from happening,
because it covers the tip of the bar where kickback is
generated. Never attempt any kind of cutting where the
SAFE-T-TIP® would have to be removed from the bar
tip.

SAFE-T-TIP

Fig. 4

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.

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 representative sample of chain
saws below 3.8 c.i.d. specified in ANSI B175.1 - 1991.

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 your 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®.

BATTERY SAFETY

■ Battery operated units do not have to be plugged
into an electrical outlet; therefore, they are always
in operating condition. Be aware of possible haz­ards even when unit is not operating.

■ 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.

■ 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.

BATTERY PACK: Item # 1322401,

1323303, 130224007,
or 130256001

CHARGER: Item # 1423701

■ 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.

■ A damaged battery pack is subject to explosion. To
avoid serious personal injury, properly dispose of a
damaged battery pack.

■ Batteries vent hydrogen gas and 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 cordless product in the presence of
open flame. An exploded battery pack can propel
debris and chemicals. If exposed, flush with water
immediately.

■ Do not charge unit in a damp or wet location.
Following this rule will reduce the risk of electric
shock.

■ For best results, your battery unit should be
charged in a location where the temperature is
more than 50°F (10°C) but less than 100°F (38°C).
Do not store outside or in vehicles.

■ Under extreme usage or temperature conditions,
battery pack leakage may occur. If liquid comes in
contact with your skin, wash immediately with soap
and water, then neutralize with lemon juice or
vinegar. If liquid gets into your eyes, flush them with
clean water for at least 10 minutes, then seek
immediate medical attention.

IMPORTANT SAFETY INSTRUCTIONS

■ Do not dispose of batteries in a fire. The cell may
explode. Batteries should be recycled, consult your
local waste authority for information regarding
available recycling and/or disposal options.

■ 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.

CHARGER SAFETY

■ Save these instructions. This manual contains
important Rules for Safe Operation and operating
instructions for charger.

■ Before using battery charger, read all instructions
and cautionary markings in this manual, on battery
charger, and product using battery charger.

■ To reduce risk of injury, charge only nickel-cad­mium type rechargeable batteries. Other types of
batteries may burst, causing personal injury and
damage.

■ Do not expose charger to wet or damp conditions.

■ Use of an attachment not recommended or sold by

the battery charger manufacturer may result in a
risk of fire, electric shock, or injury to persons.

■ To reduce risk of damage to charger body and
cord, pull by charger plug rather than cord when
disconnecting charger.

■ Make sure cord is located so that it will not be
stepped on, tripped over, or otherwise subjected to
damage or stress.

■ An extension cord should not be used unless
absolutely necessary. Use of improper extension
cord could result in a risk of fire and electric shock.
If extension cord must be used, make sure:

a. That pins on plug of extension cord are the

same number, size and shape as those of plug
on charger.

b. That extension cord is properly wired and in

good electrical condition; and

c. That wire size is large enough for AC ampere

rating of charger as specified below:
