Raising/lowering the vehicle
Once the work area, vehicle, and lift units are prepared,
perform the following steps:
1.
Position yourself so that you can see as much of the
vehicle and as many of the lifts as possible. This is
typically several feet away from either end of the vehicle.
2.
Push and release the
ENABLE
button. The button color
will change from red to green indicating the button is
ON. The button will stay ON (green) for 5 seconds after it
is released. If no other buttons are pushed during the 5
seconds the button will automatically turn OFF (red) at
the end of the 5 seconds.
3.
During the 5 seconds that the Enable button is ON
(green), push and hold the
RAISE
or
LOWER
button
to raise or lower the vehicle.
4.
As the vehicle raises or lowers, the height indicator on
the screen will update to show the current values.
5.
When the vehicle is at the desired height, release the
RAISE
or
LOWER
button.
6.
If anyone is going to be working under the vehicle, the
lifts should be
PARKED
.
7.
Depending on the amount of time the vehicle will
remain in the current position, the lift system should
be either locked or turned off. If the vehicle will be
raised or lowered before the end of the shift, the lift
system should be locked by following the steps
below. If the vehicle will be left in the raised position
longer than 8 hours, turn the master on/off switch on
all lift units in the system to the
OFF
position to
conserve the batteries.
8.
To lock the system, push the
OPTIONS
button (gear
shaped button in the top left corner). When the menu
appears, select the padlock button in the middle to
lock the system. A message will appear showing the
system is locked. When ready to unlock the system,
return communication to the unit where the lock
button was pushed (shown by the flashing yellow
position indicator) by pushing the Communication
Button and then push the
RESET
button.
There are several important safety issues to consider
when raising a vehicle or whenever a vehicle is in a
raised position, including:
All personnel should be instructed that the system
should not be unlocked unless all objects and
personnel are out from underneath the vehicle and the
vehicle, work area, and lift units are prepared for lifting
or lowering.
If the lift units are to be removed from a raised vehicle,
use only stands intended for this purpose.
Appropriate stands must be capable of supporting the
load and they must be made specifically for high-rise
supporting.
NEVER attempt to climb up, climb on, or get in a
raised vehicle. Do not open the vehicle’s doors or
make adjustments to the exterior when raised, as it
could interfere with safe lowering of the vehicle.
NEVER start the vehicle’s motor when it is supported
by the lift units or stands. Only start the engine when
the vehicle is firmly in contact with the ground and the
lift units have been removed from the wheels.
NEVER attempt to move a vehicle horizontally by any
means when it is raised on the lifts. Once the vehicle
is raised, it should only be moved up or down. Also,
NEVER attempt to move or reposition a lift unit when
a vehicle is raised on the lift unit.
NEVER subject a lift unit to dynamic loading (i.e.
“shock loading”). NEVER add objects or other weight
to the vehicle once it has been raised on the lift units.
If you experience any problems while raising the
vehicle or while it is raised, consult the “Emergency
procedures” section on page 19 and/or the
“Troubleshooting” section on page 26 of this manual.
8.8
Lowering a vehicle to the ground
WARNING!
To avoid serious injury or death, NEVER
drive the vehicle off the lifts or attempt to move a
vehicle that is elevated by the lift system.
1.
Clear the work area under the vehicle of all personnel,
tools, and equipment. Make sure there are no
obstructions under the vehicle or under the lift tables of
the lift system prior to lowering the vehicle to the
ground.
2.
If the lift system was locked, return communication to
the unit where the lock button was pushed (shown by
the flashing yellow position indicator) by pushing the
Communication Button and then push the
RESET
button. If the lift system was turned off, follow the steps
in Section 8.4 to reinitialize the system. If the lift system
was
PARKED
, refer to Section 8.10 prior to lowering
the vehicle.
3.
Position yourself so that you can see as much of the
vehicle and as many of the lifts as possible. This is
typically several feet away from either end of the
vehicle.
