Charging Batteries
Ꮨ DANGER
When using an extension cord, use only a three wire extension cord having at least
16 AWG (American Wire Gauge) wire and the same or higher electrical rating as
the devise being connected. Use of improper extension cord could result in a risk of
fire and electric shock. Three prong to two prong adapters should not be used. Use
of three prong adapters can result in improper grounding and present a shock
hazard to the user.
ƽWARNING
Never attempt to recharge the batteries by attaching cables directly to the battery
terminals.
DO NOT attempt to recharge the batteries and operate the wheelchair at the same
time.
DO NOT attempt to recharge the batteries when the wheelchair has been exposed
to ANY type of moisture.
DO NOT attempt to recharge the batteries when the wheelchair is outside.
DO NOT sit in the wheelchair while charging the batteries.
DO NOT attempt to recharge the batteries using both the on-board battery
charger AND an independent battery charger (plugged into the joystick charger
port) at the SAME time. Doing so will reduce the life of the batteries.
READ and CAREFULLY follow the manufactures instructions for each charger
(supplied or purchased). If charging instructions are not supplied, consult a qualified
technician for proper procedures prior to use.
CAUTION
New batteries MUST be fully charged prior to initial use of the wheelchair.
Always fully charge new batteries before initial use or battery life will be reduced.
As a general rule, you should recharge your batteries as frequently as possible to
assure the longest possible life and to minimize required charging time. Plan to
recharge them when you do not anticipate using the wheelchair.
