DANGER: RISK OF EXPLOSION
Always disconnect the negative battery terminal first when
removing battery cables. When reconnecting the battery
terminals, connect the positive terminal (+) first.
The order in which to remove the battery terminals is important.
The frame is connected to the negative battery terminal (grounded).
This means that with the negative terminal connected, a complete
circuit exists from the positive terminal of the battery to the frame.
Contacting the positive side and the frame simultaneously with a
metal object will cause sparks or arcing, creating a fire hazard. Also,
by this short-circuiting of the battery, hydrogen gases can be
emitted, and an explosion might occur.
