WARNING

ALWAYS use a battery lifting strap when lifting a bat- tery. It is the most convenient method and assures that the battery acid will not spill. It also helps to prolong the life of the battery.

DO NOT tip the batteries. Keep the batteries in an upright position.

Place the wheelchair in a well ventilated area where work can be performed without risking damage to carpeting or floor covering.
