Protection Device
As with all safety devices, periodic inspection and
maintenance is required to ensure the proper
operation of the pothole protection device.
This mechanism is designed to reduce ground
clearance and assist in the stability of an elevated
aerial platform in the event the aerial platform
encounters a “drop-off” or “pothole.” The nature
of this safety feature relies on maintaining a
consistent ground clearance, therefore, if the aerial
platform ever does come to rest on the pothole
device, the platform should be immediately
lowered and “locked out” to prevent further use
until a complete inspection of the mechanism is
performed by a qualified technician.

5. Make sure all battery connections are tight.
6. Replace any battery that is damaged or incapable
of holding a lasting charge.
7. Do not use any batteries other than flooded leadacid batteries of the proper AH rating.
2.17-2 Battery Charging Operation
Figure 2-25. Battery Charger
DANGER
Risk of electric shock - Do not immerse
the charger in water. Though the charger
is highly resistant to water, it is not
designed for immersion and an electric
shock can occur.
1. Provide adequate ventilation for the batteries and
charger. The convection cooled design requires
access to cooling air for proper operation. Do
not allow blankets or other materials to cover
the charger. Although the charger protects itself
against overheating, the charger cooling fins
should be cleaned if clogged with debris for best
performance.
WARNING
There could be a spark during charging.
Be careful when using fuels, solvents or
other flammables near the charger or
batteries.
2. Connect the power supply cord to a properly
grounded 100V/50 or 60Hz, 115V/50 or 60Hz, or
230V/50 or 60Hz socket. This charger automatically
senses and adjusts to the AC input voltage
range.

3. The charging time is affected by numerous
factors including battery Amp-Hour capacity,
depth of discharge, battery temperature, and
battery condition (new, old or defective). Batteries
larger than 240 AH can be recharged but will take
longer.
WARNING
Do not disconnect the DC output wires
near the batteries when the charger is
ON. The resulting arcing could cause
the batteries to explode. If the charger
must be disconnected, first disconnect
th e AC powe r suppl y cord from its
outlet, then disconnect the charger DC
connections.
WARNING
Risk of an electric shock - Do not touch
un-insulated parts of the charger output
wires, battery connector, or battery
terminals.
Charging State LED
The charger goes into an equalizing charge mode after
the batteries are charged and all 3 LEDs are “ON”. The
charger will continue to charge at a low current then
shut off automatically when complete. If all 3 LEDs
blink together, there is a problem.
Take proper action according to the following
instructions:
3 LEDs blink once simultaneously:
Output connection error. Check the battery and charger
connection. The output may not be connected to the
batteries or the connections to the batteries may have
corroded or loosened. The output may be shorted due
to improper connection to the batteries or pinched
wires. The output may be connected in reverse polarity
to the batteries. The charger is not damaged by any of

Battery Maintenance Section 2 - Operation
Batteries do not fully charge.
If the batteries are charged overnight, make sure the
AC supply is not being switched off at night with other
building items. Check battery condition and for dead
cells or reduced capacity. Replace charger only if other
problems are not found.
The AC line circuit breaker or fuse is blown.
A defective circuit breaker or fuse, an overloaded
circuit, or a charger problem can cause this condition.
Try connecting the charger to a different AC outlet
(on a different circuit) in the building. If the AC supply
checks good, the charger should be replaced.
