C. ACID BURNS (UNSEALED WET CELL BATTERIES)
Acid in batteries is corrosive. It can cause serious burns to the eyes and skin and can damage floors, fur- niture, clothing and your wheelchair.
1.Use extreme care not to spill acid when you handle batteries. Keep batteries upright.
2.Avoid contact of acid with bare skin or clothing.
3.Always wear rubber gloves and safety glasses when you handle batteries.
4.If acid contacts your skin or clothing, wash immediately with soap and water.
5.If acid contacts your eyes, immediately flood eyes with cold running water for at least 15 minutes. Seek medical attention immediately.
D.CONNECTING BATTERIES IN BATTERY COMPARTMENT
1.Batteries weigh up to 55 lbs. (25 kg). Take care to avoid injury when lifting.
2.Keep batteries upright. Take care not to spill acid (wet cell batteries).
3.Always wear rubber gloves and safety glasses when you handle batteries.
4.Before working around batteries, remove all metal personal effects, such as necklaces, rings, watches, pins and other metal jewelry that might contact battery terminal and cause
a short.
1.Lift batteries into battery compartment.
Batteries weigh up to 55 pounds (25 kg). Lifting batteries may cause back strain. If you fail to heed these warnings severe injury may occur to you.
2. Connect and disconnect battery cables with cau- tion. Connect the red lead to the positive termi- nal and the black lead to the negative terminal. Do this for each battery.

3. Tighten all terminal fasteners using two 1/2" box |
|
end wrenches to 60 | A |
4. Place the battery compartment lid on power |
|
base and secure using the two (2) quarter turn |
|
fasteners (push down on fasteners). |
|
Never make direct contact across both battery |
|
terminals, as an explosion may occur. A spark |
|
may result in an explosion and/or fire resulting |
|
in severe injury or death. |

E. CHARGING BATTERIES
To avoid the risk of severe injury or death from electrical shock, fire or explosion while charging:
1.Never connect charger to a 240 volt source. The main input voltage is 110 volts. For wheelchair manuals to be used outside the U.S. omit (1).
2.Never touch the charger after it is connected to an electrical outlet. This may cause electri- cal shock.
•Connect charger to the power supply ONLY AFTER you connect charger to the battery. •Never connect or disconnect charger from battery while there is power to the charger.
3.Never use an extension cord. Use of an improper cord could damage the charger, or cause a fire or electrical shock.
4.A battery emits explosive hydrogen gas during charging. To reduce the risk of fire or explosion: •Make sure area is well vented. Never charge battery in a
•Never smoke or allow a spark, flame or high heat near battery during changing.
•Never allow metal tools or chair parts to make direct contact across both battery terminals.
5.Never look directly into cells when charging battery.
