connections can result in component damage and
hazardous conditions.

with hot or live circuits could result
in death or serious injury. Remove
all rings, watches and other
jewelry.
Bodily injury hazard. Batteries
contain acid. Avoid spilling or
contacting battery acid. Neutralize
battery acid spills with baking soda
and water.

clear of the battery cover when
lowering the platform.
