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 fi re.
• Under abusive conditions, liquid may be eject-
ed from the battery; avoid contact. If contact
accidentally occurs, fl ush with water. If liquid
contacts eyes, additionally seek medical help.
Liquid ejected from the battery may cause irritation

• WARNING: Some dust created by power sanding,
sawing, grinding, drilling, and other construction
activities contains chemicals known to cause
cancer, birth defects or other reproductive harm.
Some examples of these chemicals are:
•lead from lead-based paint
•crystalline silica from bricks and cement and other
masonry products, and
• arsenic and chromium from chemically-treated
lumber.
Your risk from these exposures varies, depending
on how often you do this type of work. To reduce
your exposure to these chemicals: work in a well
ventilated area, and work with approved safety
equipment, such as those dust masks that are spe-
cially designed to fi lter out microscopic particles.
