3.Tighten all terminal fasteners using two 1/2" box
end wrenches to 60 in-lbs (6.8 N.m).
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 closed-in area.
•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.
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.
