be observed to obtain good performance and
maximum cycle life.
CAUTION: ALWAYS WEAR PROTECTIVE
EYE SHIELDS AND CLOTHING WHEN
WORKING WITH BATTERIES. BATTERIES
CONTAIN ACID WHICH CAN CAUSE BODILY
HARM. DO NOT PLACE WRENCHES OR OTHER
METAL OBJECTS ACROSS THE BATTERY
TERMINALS OR BATTERY TOP. ARCING OR
EXPLOSION OF THE BATTERY MAY RESULT.
SOMEONE SHOULD BE WITHIN THE RANGE OF
YOUR VOICE OR CLOSE ENOUGH TO COME TO
YOUR AID WHEN YOU WORK NEAR A LEAD-
ACID BATTERY. HAVE PLENTY OF FRESH
WATER AND SOAP NEARBY IN CASE BATTERY
ACID CONTACTS SKIN, CLOTHING, OR EYES.
WARNING: RISK OF EXPLOSIVE GASES.
WORKING IN VICINITY OF A LEAD-ACID
BATTERY IS DANGEROUS. BATTERIES
GENERATE EXPLOSIVE GASES DURING
NORMAL BATTERY OPERATION. FOR THIS
REASON, IT IS OF UTMOST IMPORTANCE THAT
EACH TIME BEFORE USING YOUR CHARGER,
YOU READ THIS MANUAL AND FOLLOW THE
INSTRUCTIONS EXACTLY.
1.
New batteries should be given a full charge
before their first use because it is difficult to
know how long the batteries have been stored.
2.
Limit use of new batteries for first 5 cycles. New
batteries are not capable of their rated output
until they have been discharged and charged a
number of times.
3.
Do not excessively discharge batteries.
Excessive discharge can cause polarity reversal
of individual cells resulting in complete failure
shortly thereafter. Limited use of new batteries
will minimize the risk of cell reversals.
4.
CHECK THE LEVEL OF THE ELECTROLYTE
IN CONVENTIONAL LIQUID ELECTROLYTE
LEAD ACID BATTERIES MONTHLY.
MAINTAIN THE PROPER ELECTROLYTE
LEVEL BY ADDING DISTILLED OR PURIFIED
WATER WHEN NECESSARY. Electrolyte
levels fall during discharge and rise during
charge. Therefore, it is mandatory that water be
added to the cells ONLY when they are fully
charged; do not overfill. Old batteries require
more frequent additions of water than new
batteries.
5.
Keep tops of batteries clean and dry to prevent
excessive self-discharge. Keep the battery
terminals reasonably tight.
PERSONAL PRECAUTIONS
1.
Someone should be within the range of your
voice or close enough to come to your aid when
you work near a lead-acid battery.
2.
Have plenty of fresh water and soap nearby in
case battery acid contacts skin, clothing, or
eyes.
3.
Wear complete eye protection and clothing
protection. Avoid touching eyes while working
near battery.
4.
If battery acid contacts skin or clothing, wash
immediately with soap and water. If acid enters
eye, immediately flood eye with running clod
water for at least 10 minutes and get medical
attention immediately.
5.
NEVER smoke or allow a spark or flame in
vicinity of batteries.
6.
Be extra cautious to reduce a risk of dropping a
metal tool onto battery. It might spark or short-
circuit battery or other electrical part that may
cause explosion.
7.
Remove personal metal items such as rings,
bracelets, necklaces, and watches when working
with a lead-acid battery. A lead-acid battery can
produce a short-circuit high enough to weld a
ring or the like to metal, causing a severe burn.
8.
NEVER charge a frozen battery.
DUAL MODE WHEELCHAIR CHARGER
TROUBLESHOOTING
CAUTION: DO NOT DISASSEMBLE THE
CHARGER. TAKE IT TO A QUALIFIED SERVICE
AGENT WHEN SERVICE OR REPAIR IS
REQUIRED. INCORRECT REASSEMBLY MAY
RESULT IN A RISK OF ELECTRIC SHOCK OR
FIRE. THE FOLLOWING PROCEDURES ARE
INTENDED ONLY TO DETERMINE IF A
MALFUNCTION MAY EXIST IN THE CHARGER,
OR IN THE WHEELCHAIR AND BATTERIES.
DANGER: TO REDUCE RISK OF ELECTRIC
SHOCK, ALWAYS DISCONNECT BOTH THE
POWER SUPPLY CORD AND THE OUTPUT
CORD BEFORE ATTEMPTING ANY
MAINTENANCE OR CLEANING.
CAUTION: DO NOT OPERATE THE
CHARGER IF IT IS DAMAGED OR APPEARS TO
BE MALFUNCTIONING. PERSONAL INJURY OR
DAMAGE TO THE CHARGER AND/OR
BATTERIES MAY RESULT.
