Charging the batteries is the most important part of operating and maintaining your power wheelchair. Be sure to do
it properly!
IMPORTANT:
Only AGM or gelcell sealed lead-acid deep cycle discharge type batteries should be
used with this wheelchair. Do not use regular car starter batteries. AGM and gelcell batteries do not require water
and they have no danger of spillage. Some are approved by the Federal Aviation Administration for air travel.
Important Safety Information:
Always use caution when lead-acid batteries are being charged. Batteries can generate explosive gasses
during charging. Observe the follow guidelines to reduce risk of battery explosion.
1. Never smoke or allow open fl ame or sparks around a charging battery.
2. Never charge a frozen battery.
3. Use a PaceSaver charger designed for charging deep-cycle gelcell and AGM batteries.
4. The user is instructed to NOT use the charger with a battery confi guration not matching the output
voltage rating of the charger. The batteries in this unit are connected for 24 volts.
5.The charger is rated at 24 volts DC and includes a special safety circuit to prevent operation of the unit
while charging. This is to prevent accidently driving away with the AC cord connected, causing damage to
the cord and to the receptacle in the user's residence.
6. Do not operate the charger in closed area or restrict ventilation around the charger in any way.
7. Do not disconnect the DC portion of the charger circuit while the AC cord is still connected to the
electrical outlet.Unplug the AC cord fi rst.
8. It is normal for the charger to operate at a high temperature. Do not touch the hot charger until after it cools.
Basic Safety Instructions:
1. Do not expose the charger to rain, snow or other moisture sources (i.e., sprinkler, car wash, etc.). When
storing the unit, keep it inside a building or under a protective covering.
2. Use of the charger in a manner not recommended by the manufacturer may result in the risk of fi re,
electrical shock or personal injury.
3. To reduce the possibility of damage to the AC cord or the connector, disconnect the AC line cord by
grasping the plug and not the cord, when disconnecting from either the unit or the wall receptacle.
4. Locate cord so that it will not be stepped on, tripped over or subjected to the possibility of damage.
5. An extension cord is not recommended for use with this equipment. Use of an improperly rated extension
cord could result in risk of fi re or electrical shock. Should it be required to use an extension cord, make
certain that it is of 3-wire construction and has a wire size of at least 16-gage, and the cord must be in good
electrical condition.
6. Do not operate this charger with damaged AC cord or receptacle. If they are damaged, replace them
immediately.
7. Do not disassemble the charger. If there is a perceived problem with the equipment, refer to the servicing
section of this manual or refer to a qualifi ed technician for service. Incorrect assembly of the charger could
result in a risk of electrical shock or fi re.
8. Do not operate the charger if it has received an impact of a severity that may render it inoperative. Take it
to a service technician.
9. To reduce the risk of electrical shock, unplug the charger from the electrical outlet before attempting any
maintenance or cleaning.
10. Operate the charger on a fl at surface. Restricting air fl ow around the charger can create an overheated
condition. Carpeted fl oors can restrict air fl ow. It is normal for the charger to operate at a high temperature.
11. Do not operate the charger with a damaged cord or plug. Do not operate if the charger looks like it has
been damaged. Contact your dealer for repair.
NOTICE:
The battery charger provided is specially designed for use with PaceSaver brand equipment. In
the unlikely event of failure it should be replaced only with a PaceSaver approved charger to assure proper
performance of the charger and wheelchair.
