Maintenance of the Pothole
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.

ON. The resulting arcing could cause the
batteries to explode. If the charger must
be disconnected, first disconnect the AC
power supply 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.
WARNING
Visually and manually inspect to verify
the DC output wires and terminals are in
good working condition before each use.
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
these problems.
3 LEDs blink twice simultaneously:
The charger is indicating that the AC voltage is too low
or too high. Check the AC input voltage.
3 LEDs blink three times simultaneously:
Charger is overheated. No action required. When
the charger cools, charging will restart automatically.
Check and correct for dirt or other debris on charger
that may be reducing cooling.
3 LEDs blink four times simultaneously:
Input or output over current. No action required,
charger will correct and restart automatically.
100% LED lamp blinks:
Charger 18-hour timer has timed out due to battery
problem.
4. The charger will start automatically within four
to six seconds. The charger will start even with
severely discharged batteries (down to 1V terminal
voltage). Once charging starts, the LEDs indicate
the charging progress.

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:
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.

LCP - Locally Concentrated Pressure is a measure of how hard the aerial platform
presses on the areas in direct contact with the floor. The floor covering (tile, carpet,
etc.) must be able to withstand more that the indicated values above.
OUP- Overall Uniform Pressure is a measure of the average load the aerial
platform imparts on the whole surface directly underneath it. The structure of the
operating surface (beams, etc.) must be able to withstand more than the indicated
values above.
structure and is generally determined by the engineer or architect for that particular
structure (see Floor Loading Pressure chart below).
Intermixing tires of different types or using tires of types other than those originally supplied with
