Section 3 - Operation Component Identification
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 MEWP in the event the MEWP
encounters a “drop-off” or “pothole.” The nature
of this safety feature relies on maintaining a
consistent ground clearance, therefore, if the
MEWP 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 technician.

Figure 3-4. Maintenance Support
1. Maintenance Support - The maintenance support
is a safety mechanism designed to support the
scissor assembly. When properly positioned it
can support the scissor assembly and empty
platform. The maintenance support must be used
when inspection and/or maintenance is to be
performed within the lifting mechanism. Refer to
Section 3.12 for procedure on how use and store
the maintenance support.
WARNING
The maintenance support must be used
when inspection and/or maintenance or
repairs are to be performed within the
lifting mechanism. Failure to use this
safety mechanism could result in death
or serious injury.
WARNING
Do not reach through the scissor
assembly when the platform is raised
without the maintenance support properly
positioned. Failure to avoid this hazard
could result in death or serious injury.
