Battery Precautions

NOTE: When servicing batteries observe the following precautions:

^ Be sure battery is properly connected before attempting to start engine.
^ Avoid creating sparks near battery. Batteries produce explosive gas (hydrogen) and contain acid.
^ Never disconnect battery when engine is running.
^ Always be sure battery cables are disconnected before charging battery.
^ Never attempt to start engine or charge battery using a booster/starter with a voltage rating above 12 volts.
