Manual Operating Instructions
In event of power or equipment
failure, refer to the Manual
Operating Instructions to manu-
ally operate the lift. Refer to the
Lift Operating Instructions for all
normal lift operation procedures
(such as loading and unloading
passengers). Follow all Lift
Operation Safety Precautions
at all times!
Familiarize yourself with the
components necessary to
manually operate the lift. The
T-handle release cable re-
leases and engages the lift
platform to allow the platform
to be manually extended and
retracted. The manual back-
up pump (hand pump) is
used to manually lower and
raise the extended platform.
The location of the power
pack and release cable var-
ies from vehicle to vehicle
(depending on your particular
installation).
Note: Location of power
pack and T-handle varies.
Cable-Activated Platform Manual Release System
Platform Manual Release Sys-
tem: A cable-activated manual
release system releases and
engages the platform carriage
assembly drive chain to allow the
platform carriage assembly to be
manually moved out (extended)
or moved in (retracted) as need-
ed. A T-handle is provided on the
release cable for activation of the
manual release system (details
follow).
After manually moving the
platform in or out, it is extremely
important that the cable-acti-
vated manual release is positively
re-engaged to secure (lock) the
platform carriage assembly before
loading a passenger on the plat-
form or before driving the vehicle.
Grasp the outer barrier and move
the platform in and out until the
platform locks (chain release
assembly engages), securing the
platform carriage assembly within
the housing. You will feel the
release mechanism engage.
Failure to manually lock the plat-
form carriage assembly (re-en-
gage the carriage assembly drive
chain) after manual deployment,
will allow the platform to roll in or
out of housing unhindered during
vehicle movement. Failure to lock
the platform will also allow the
platform to roll in or out of hous-
ing unhindered during hand pump
raising and lowering procedures.
After manually releasing
platform, push manual release
T-handle in fully and ensure
platform is locked before driv-
ing lift vehicle. Uncontrolled
and unintentional platform de-
ployment (inadvertent platform
ejection) may result in serious
bodily injury and/or property
damage.
Note: The lift platform must be
pushed back into its carriage
compartment all the way before
reverting back to normal (pow-
ered) operation. When the lift is

Push T-handle in fully and
manually move platform in
and out to engage platform
lock before driving vehicle.
Failure to lock platform may
result in unintended platform
deployment. Unintended
platform deployment may
result in serious bodily injury
and/or property damage.
fully extended manually, it does
not activate the proper switches
for normal operation. Returning
(moving) the lift in fully in allows
for proper switch activation.
