WARNING!
READ AND UNDERSTAND ALL INSTRUCTIONS. Failure
to follow all instructions listed below, may result in electric
shock, fire and/or serious personal injury.
Battery tools do not have to be plugged into an electrical
outlet; therefore, they are always in operating condition.
Be aware of possible hazards when not using your bat-
tery tool or when changing accessories. Following this
rule will reduce the risk of electric shock, fire, or serious
personal injury.
Do not place battery tools or their batteries near fire
or heat. This will reduce the risk of explosion and possibly
injury.
 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 bat-
tery immediately.
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 cordless product in the pres-
ence of open flame. An exploded battery can propel debris
and chemicals. If exposed, flush with water immediately.
Do not charge battery tool in a damp or wet location.
Following this rule will reduce the risk of electric shock.
For use only with 24 V Li-Ion chargers, see tool/appliance/
battery pack/charger correlation supplement 988000-446.
Do not charge battery in an area of extreme heat or cold.
It will work best at normal room temperature. To reduce
the risk of serious personal injury, do not store outside or in
vehicles.
Under extreme usage or temperature conditions, battery
leakage may occur. If liquid comes in contact with your
skin, wash immediately 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.
Following this rule will reduce the risk of serious personal
injury.
 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 terminals
together may cause sparks, burns, or a fire.
 Always remove battery pack from your tool when you
are assembling parts, making adjustments, cleaning,
or when not in use. Removing battery pack will prevent
accidental starting that could cause serious personal injury.

RYOBI LITHIUM-ION BATTERY PACKS
Lithium-ion batteries deliver fade free power for their entire run
time. 24 V lithium-ion tools will not gradually lose power due
to decreasing battery charge. Instead, power from the battery
pack will drop from full to zero once the full charge has been
drained from the battery. Once this happens, recharging of the
battery is required. It is not necessary to drain the battery pack
completely before recharging.
BATTERY PROTECTION FEATURES
Ryobi 24 V lithium-ion battery packs are designed with features
that protect the lithium-ion cells and maximize battery life.
If the tool stops during use, release the trigger to reset and
resume operation. If the tool still does not work, the battery
needs to be recharged.
COLD WEATHER OPERATION
The lithium-ion battery pack can be used in temperatures down
to –4°F. Put the battery pack on a tool and use the tool in a light
duty application. After about a minute, the pack will warm up
and begin operating normally.
