sensation, get medical
attention immediately.
Wear eye protection when
charging or working near a bat-
tery.

when working in an enclosed
space.

excessive pressure on the case may
cause battery acid to leak, resulting in
personal injury. Lift with a battery
carrier or with your hands on opposite
corners.

when the battery cables are con-
nected.
