*NOTE: The Battery Lifting strap supplied is for Group 22 Batteries ONLY. Refer to the battery manufacturer for the proper lifting strap and/or battery tools for U1 battery removal/installation.

WARNING

ALWAYS use a battery lifting strap when lifting a battery. 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.

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. Be- fore 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, observe polarity markings located on the ends of the battery lifting strap, (+) side to POSITIVE (+) battery terminal/post and (-) side to NEGATIVE (-) battery ter- minal/post.

1.If necessary, remove the battery boxes from the wheelchair. Refer to INSTALLING/REMOVING BAT- TERY BOXES in PROCEDURE 10 - FWD or PRO- CEDURE 11 - RWD of this manual.

2.Secure the battery lifting strap to battery terminal(s)/ post(s) (FIGURE 1).
