2.5.1 Safety mechanisms
The vehicle lift has a control and monitoring system, which ensures that:
• The guide blocks always stay at an equal height within the control limits.
• Lowering is halted in the event that obstacles cause an elevation difference
to occur.
• The control circuit is interrupted in the event that the height difference
between the guide blocks exceeds a pre-defined value; operation via the
push buttons on the column lift control boxes is disabled then.
• Lifting is halted when the highest position is reached (height safeguard).
• The lowering action stops 30 cm above the floor. If the [DOWN] and
[UNLOCK] buttons are pressed again, the column will be lowered further

Installation and Service Manual 13 SK 2055 / 2070 / 2090
with an accompanying acoustic signal. This option (foot protection) can be
enabled or disabled, by default it is disabled.
• Lowering is electro-mechanically blocked in the event of loss of control power
or leakage from the cylinders.
2.5.2 Emergency stop switch
The main switch of the Freedomlift functions as an emergency stop switch. Use
the emergency stop switch only in case of emergencies. If the emergency stop
is used, check:

2.6 Lock-out/tag-out
Lock-out or tag-out procedures are safety measures, designed to prevent
application of power (energy) to the machine while it is being serviced. The
procedures for the application of energy control (the lock-out or tag-out
procedures) must be done in the prescribed sequence.
2.6.1 Lock-out/tag-out procedure
1. Notify all affected employees that service or maintenance is required on the
machine and that the machine must be shut down and locked out.
2. Preparation for shut-down. The machine may only be turned off by an
authorized employee. Before turning it off, the employee must know:
• The type and magnitude of the energy.
• The hazards of the energy to be controlled.
• The method or means to control the energy.
3. Shut-down. If the machine is in operation, shut it down by the normal shut-
down procedure.
4. Machine isolation. Isolate the machine from the energy source(s). The
machine uses AC power. This is de-energized by removing the AC
connection to the machine.
5. Lock-out (or tag-out) device application. Lock out the energy isolating
device(s) with:
• An individual lock(s).
• A warning device on the main switch.
6. Remove residual or stored energy. Stored or residual energy (such as
that in capacitors, air pressure, etc.) must be dissipated or restrained by
methods such as grounding, bleeding down, etc.
7. Verification of isolation. Make sure that the machine is disconnected from
the energy source(s). First make sure that no persons are in or on the

Installation and Service Manual 14 SK 2055 / 2070 / 2090
machine. Test to verify the isolation of the machine. Make certain that the
machine will not operate (power cannot be turned on).
The machine is now locked out.
Return all operating control(s) to the OFF position after verifying the isolation of
the machine.
2.6.2 Ending lock-out/tag-out procedure
1. Make sure the service or maintenance is completed and the machine is
ready to return to normal operation.
2. Check the machine and the immediate area around to make sure that all
non-essential items have been removed.
3. Make sure that all components of the machine are operationally intact.
4. Make sure that all persons are at a safe distance from the machine.
5. Verify that the power switch is in the OFF position.
6. Remove the lockout devices.
