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 next to the latch on the battery
tray.
Figure 6.1 – Battery Tray
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 outlet (115
volt AC, 60 Hz) using a 3 conductor, 14 gauge or
larger extension cord. The extension cord must be
as short as possible and in good electrical condition.
The charger will turn on three to five seconds after a
complete electrical connection is made. The amme-
ter (refer to Figure 6.1) will indicate near 20 amps
initially then taper off to 5 to 10 amps as the batter-
ies charge.
Note
If the batteries are fully charged when the charger is
plugged in, the ammeter will initially read 15 to 20 amps
then quickly read zero.
4. Leave the charger plugged in until it shuts itself off.
5. Unplug the extension cord after the battery charger
turns itself off. Allow the batteries to cool off after
charging.
6. Check the battery water level. Add water to individual
cells only if the plates are exposed. Replace the bat-
tery caps.
Chapter 6 – Batteries
The battery tray contains 4, 220 amp hour, 6 volt batter-
ies. These batteries supply 24 volt DC electrical power to
operate the aerial platform drive and platform control sys-
tems. Proper machine operation depends on well main-
tained 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 unavoidable.
A
Warning
Battery acid can damage the skin and eyes. Serious
infection or reaction can result if medical treatment
is not given immediately. Wear face and eye pro-
tection 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.
