NOTE: If there is battery acid in the bottom or on the sides of
the battery box(es) or battery(ies), apply baking soda to these
areas to neutralize the battery acid. Before reinstalling the
NEW or existing battery(ies), clean the baking soda from the
battery box(es) or battery(ies).
NOTE: When securing battery lifting strap to battery, ob-
serve polarity markings located on the ends of the battery
lifting strap, (+) side to POSITIVE (+) battery post and (-) side
to NEGATIVE (-) battery post.
1. If necessary, remove the battery boxes from the wheel-
chair. Refer to

tery case. Batteries which interfere with the bat-
tery box cannot be used for these applications.
Attempting to “wedge” a battery into a battery
box may damage the box and/or the battery.

upright position.
Place the wheelchair in a well ventilated area
where work can be performed without risking
damage to carpeting or floor covering.
The warranty and performance specifications con-
