A. INTRODUCTION
1. Notes:
• Batteries supply the power for your chair.They contain a finite amount of
energy and have limits on how long they can store and supply energy.
• You can charge batteries only a certain number of times before they will
fail and no longer hold a charge.
• For answers to questions about batteries,consult your Sunrise supplier.
2. Use Proper Batteries:
Your chair operates on two 12 volt batteries.
• They should be 22 NF or U1 size with a minimum of 30 ampere hour rat-
ing. Only deep cycle sealed case construction batteries should be used
in this device.
• When you buy a replacement,insist on a deep cycle sealed case type.
Do not use a car starter battery.
3. Breaking In:
• A battery requires “breaking-in” for the first 6 to 12 charges. It will not
accept a full charge for this period.
• It is best to limit the length of your trips until you break the batteries in
and you know the range of your chair.
4. Discharged Batteries:
• Never allow a battery to completely discharge. If you operate your wheelchair
until it has almost stopped,you will greatly reduce the life of your batteries.
• Never let a battery sit in a discharged condition. Give unused or stored
batteries a full charge once per month.
• Always fully charge the batteries.Avoid“topping off” with frequent charges.
Never connect a life support or auxiliary device to a wheelchair battery.The electrical
system may fail, and result in severe injury to or death of rider.

Note: If your speed becomes hard to manage, release the Joystick and the chair will come
to a complete stop.
• When you release the joystick it will return to neutral;the chair will slow
to a stop and the motor locks will reengage.
• We recommend that you switch the chair off if you stop for any length of
time.This will conserve battery power.
Note: Once the chair stops, switching the chair off will not affect the motor locks.
6. Joystick Boot (H)
Make sure the boot is not torn or cracked (this could allow debris, water or
moisture to enter).If the boot is torn or cracked, replace it as soon as you can.
1. Never use the ON/OFF switch to stop your chair except in an emergency.
This will result in an abrupt stop,and may cause you to fall.
2. To slow or stop your chair,return the joystick to neutral.
F. MOTOR LOCKS
Disconnect the motor locks when you need to manually push the chair.
(For example, in an emergency,or if batteries fail).
1. Do not disengage motor locks unless power to the chair is off.
2. Be aware that the chair will not have brakes in the free-wheel position.
3. Make sure that the person pushing the chair has full control when motor
locks are disengaged.
