Chapter 6 – Batteries
The battery tray on the right side of the chassis, contains
four, 235 amp, 6 volt batteries to operate the aerial plat-
form drive and control systems.
To access the batteries, pull the latch on the battery tray
outward and swing the tray open.
For optimal battery performance the battery fl uid level
must be maintained and the battery connections must
be kept clean.
General Maintenance
Always keep the batteries clean, free of dirt and corrosion.
A fi lm on top of the battery can accelerate discharge.
A
Warning
Battery acid can damage the skin and eyes. Serious
infection or reaction could result if medical treatment
is not given immediately. Wear face and eye protec-
tion when working near the batteries.
If necessary, clean the batteries, terminals, and cable
ends (refer to Figure 6.1) with a wire brush or terminal
cleaning tool.
Figure 6.1 – Battery Tray
Use distilled water to refi ll the batteries. Avoid water
containing metallic solids such as iron which can reduce
the life of the batteries.
Consult a battery charger specialist if extreme tempera-
ture use is unavoidable.
Cold reduces battery capacity and retards charging.
Heat increases water usage and can result in over-
charging.
Very high temperatures can cause thermal run away
which may lead to an explosion or fi re.

Charging
The aerial platform is equipped with a 25 amp automatic
battery charger that will completely recharge the batteries
and turn off after the charge cycle is completed. The bat-
tery charger is located on the right side of the chassis.
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 fl ame.
A
Caution
The batteries may 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.
It may take from 1½ to 16 hours to recharge the batteries
depending on the amount of discharge. If the charging
cycle exceeds 16 hours without the batteries being fully
recharged, unplug the charger and have the batteries
checked.
Fully recharge the batteries, immediately after use.
One charging cycle per day is preferred.
Fully charged batteries 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 dis-
charge the battery a few times.
Use the following procedure to charge the batteries.
1. At the lower controls, turn the start switch to the off
position.
2. Open the battery tray on the right side of the chassis.
Make sure the battery disconnect is fully connected
(refer to Figure 6.1).
3. Remove the caps from each battery (refer to Figure
6.1).
4. Visually check the battery fl uid level making sure the
level is within ¼″ (6 mm) of the bottom of the fi ller neck
inside each hole. If needed, add distilled water.
5. Tightly replace the caps on each battery, and close
the battery tray.
