Emergency Procedures
10.1
Emergency stop
In the event that the system must be stopped
immediately, the
lift system
has an emergency stop
button provided on each lift (see the “Component
identification” section on page 8). It is red in color and
simply needs to be pushed in on any lift unit to halt a
vehicle lift or lowering that may be in progress. The
normal emergency stop condition, or “E-Stop”, message
on the display will communicate with all lift units
synchronized in the system to halt all at once. After the
situation is assessed and it is determined that it is safe
to continue lifting or lowering, the emergency stop
button originally pushed in can be pulled back out and
the
RESET
button pushed to reset the system. The
RESET
button must be pushed after establishing
communication with the lift that the emergency stop
button was activated on.
In the unlikely event that the system would lose
communication at the same time an emergency stop
button is pressed and a lift unit is still moving, simply press
the emergency stop button on the lift unit that is still
moving. If this fails to stop the lift unit, turn the master
on/off switch, located on the right side of the enclosure
(see the “Component identification” section on page 8),
to the
OFF
position, disconnect the air hose from the air
inlet if necessary, and ensure the down stop is in the
engaged position by pulling the Down Stop Handle
toward the back of the lift unit. If this is the case, one of
the valves may be stuck and need to be inspected,
cleaned, and/or replaced (see section 12.4 of this
manual).

10.2
Manual lowering
Manual operation is intended for use when the normal
controls are not functioning, and is NOT to be used
for normal operation.
Any time the controls are found to not be functioning while a
vehicle is already raised, the vehicle may be lowered to the
ground using the following steps:
1.
Station a person at each lift unit.
2.
Ensure that the master on/off switch, located on the
right side of the enclosure (see the “Component
identification” section on page 8), is in the ON
ON
ON
ON
position.
3.
Each person must prepare to hold the manual
raise/lower
toggle
switch
down
while
the
Communication Button is held in (see the “Component
identification” section on page 8).
4.
Each person should simultaneously hold the
Communication Button and Manual Raise/Lower
Toggle Switch to initiate lowering (see
the
“Component identification” section on page 8).
5.
Coordinate lowering by individually stopping and
starting, if necessary, in order to keep the lifts at the
same height.
If one or more lift unit(s) does not move down initially, it may
be resting on a down stop lug. Slightly raise the lift to clear
the down stop lug. The lift is manually raised by holding the
manual
raise/lower
toggle
switch
up
while
the
Communication Button is held in. Once the lift is clear of
the down stop lug, lowering can resume.
