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 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 rating.
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.
B. BATTERY CHARGER
A battery charger produces a direct current (DC).When applied to a
discharged battery, this reverses the chemical reaction that led to its discharge.
1. Charge Rate. How fast a battery will charge depends on:
• Its electrical capacity; state of charge; electrolyte temperature, and;
internal condition.
• The DC output of the charger. (The charge rate will vary if the alternating
current (AC) supply is higher or lower than 110 volts).
2. Caution — To Avoid Damage to the Charger:
• Never place the charger on top of a battery during charging. (Gases from
the battery can damage the charger and may lead to an explosion or fire).
XI. BATTERIES
X. OPERATING GUIDE
• 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 (F)
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.
7. Remote Switch Jacks (optional– not shown)
Two 1/8" switch jacks are optional to provide remote switch control of the on/off
power function and the mode select function. Any of the single switches offered
by Sunrise Medical can be used to connect to either or both of these jacks
(except the single zero touch switch).
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.
G. 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.
1. To Disengage Motor Locks
Push Lever (A) Down to the free-wheel
position.
2. Engage Motor Locks
Push the lever (A) up into the drive
position.
