It may take from 1 1 /
2
to 16 hours to recharge the batter-
ies depending on the amount of discharge. If the charg-
ing cycle exceeds 16 hours without the batteries being
fully recharged, shut off the charger and have the batter-
ies checked.
Use the following procedure to charge the batteries.
1. Turn the battery disconnect switch off (refer to Figure
6.1). The switch is on the lower control panel.
Figure 6.1 – Lower Controls
2. Check the battery water level. Add water to individual
cells only if the plates are exposed. Replace the bat-
tery caps.
3. Plug the charger into a properly grounded AC outlet
using a 3 conductor, 14 gauge or larger extension
cord. The extension cord must be as short as pos-
sible and in good electrical condition. Make sure the
AC voltage selector switch on the charger is set to
the same voltage as the outlet voltage. The charger
will turn on three to five seconds after a complete
electrical connection is made. The ammeter (refer to
Figure 6.2) will indicate near 40 amps initially then
taper off to 5 to 10 amps as the batteries charge.

Chapter 6 – Batteries
The battery tray contains 4, 220 or 240 amp hour, 6 volt
batteries. These batteries supply 24 volt DC electrical
power to operate the aerial platform drive and platform
control systems. Proper machine operation depends on
well maintained and charged batteries.
General Maintenance
Always keep the batteries clean, free of dirt and corro-
sion. A film on top of the battery can accelerate discharge.
Cold reduces battery capacity and retards charging. Heat
increases water usage and can result in overcharging.
Very high temperatures can cause thermal run away
which may lead to an explosion or fire. Consult a battery
charger specialist if extreme temperature use is unavoid-
able.
A
Warning
Battery acid can damage the skin and eyes. Seri-
ous infection or reaction can result if medical treat-
ment is not given immediately. Wear face and eye
protection when working near the batteries.
Use distilled water to refill the batteries. Avoid water con-
taining metallic solids such as iron.
Charging
Fully recharge the batteries, immediately after use. One
charging cycle per day is preferred. Fully charged batter-
ies perform best. The deeper the discharge, the fewer
number of cycles a battery will deliver. Deep discharges
deteriorate the battery quicker than light shallow cycles.
An overly discharged battery may need to be cycled a
few times before it can fully recover. If a battery begins to
heat before becoming fully charged, it may be necessary
to recharge and discharge the battery a few times.
The aerial platform is equipped with an automatic battery
charger that will completely recharge the batteries and
turn off after the charge cycle is completed.
A
Warning
Batteries give off hydrogen and oxygen that can com-
bine explosively. Death or serious injury can result
from a chemical explosion. Charge the batteries
only in a well ventilated area away from sparks or
flame.
A
Caution
The batteries can be overcharged and/or damaged
if the charger fails to shut off automatically. Do not
leave the battery charger on for more than two days.
