and the work to be performed. Use of the pow-
er tool for operations different from those intend-

 Recharge only with the charger specified by
the manufacturer. A charger that is suitable for
one type of battery pack may create a risk of fire
when used with another battery pack.
 Use power tools only with specifically desig-
nated battery packs. Use of any other battery
packs may create a risk of injury and fire.
 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 termi-
nals together may cause burns or a fire.
 Under abusive conditions, liquid may be eject-
ed from the battery; avoid contact. If contact
accidentally occurs, flush with water. If liquid
contacts eyes, additionally seek medical help.
Liquid ejected from the battery may cause irrita-
tion or burns.
