Chapter 8. Prestart Inspection
Potential service and safety problems may be detected
by inspecting the aerial platform. This chapter includes
information on properly inspecting the aerial platform
and includes a prestart inspection check list at the end
of the chapter to ensure that no areas are overlooked.
The potential for an accident increases when oper-
ating an aerial platform that is damaged ormalfunc-
tioning. Death or serious injury can result from
such accidents.Donot operate the aerial platform if
it is damaged or malfunctioning.
Perform a prestart inspection at the beginning of each
shift, before using the aerial platform on the job. The in-
spection site must have a smooth and level surface.
Operator’s Manual
The manual holder is located at the inside the platform
(refer to Figure 8.1) at the front of the machine. Make
certain it is securely fastened in place.
Figure 8.1—Operator’s Manual Holder
Checkto see that the proper Operator’s Manualis in the
holder. The manual should be complete with all pages
intact and in readable condition.
Electrical System
Electrical power is supplied from 4,220 amp hour, 6volt
batteries. These batteries supply 24 volt DC electrical
power to operate the aerial platform drive and control
system.
Batteries give off hydrogen and oxygen that can
combineexplosively.Death or serious injurycanre
-
sult from a chemical explosion. Do not smoke or
permit open flames or sparks when checking the
batteries.
Even with low voltage electrical systems, severe
arcing can occur. Electrical shock or component
damage can result from contact with energized
conductors. Use caution when working with any
electrical device.
The batteries are in the swing-out tray on the left side of
the aerial platform.
Battery Fluid Level
Removethecapsfromeach battery(refer to Figure 8.2).Vi-
sually check the battery fluid level. If the level is not within
1
/4″ (0.6 cm) of the bottom of the filler neck inside each
hole, add distilled water.
Figure 8.2—Batteries
Replace the caps on the batteries. The caps must be in
place and tight during machine operation and battery
charging.
Battery Terminals
Check the top of the batteries, the terminals, and cable
ends(refer to Figure 8.2).They should be clean and free
of corrosion and dirt. Clean the top of the batteries if
necessary. Clean the terminals and cable ends with a
wire brush or terminal cleaningtool.All cable ends must
be securely fastened to the terminals.
Battery Charger
Inspect the battery charger (refer to Figure 8.3) to en-
sure that it is operating properly.
1. Turn the battery disconnect switch off.
2. Plug the charger into a source of power.
