10. Emergency  Procedures

 

 

10.1  Emergency  stop

 

 

In the event that the system must be stopped immediately, 
the lift system has an emergency stop button located on 
the door just  below the touch screen (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 will  communicate with all  lift 
units  synchronized in  the system to halt all lift units 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 on the lift unit where the 

emergency stop button was activated

 

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  left  side  of  the control 
enclosure (Fig. 2, Pos. 3), to the

 

OFF

 

position. If this is the 

case, then the motor starter solenoid has likely welded 
shut and will have to be replaced before manual lowering 
can occur. Contact the manufacturer for instructions on 
replacing the motor starter solenoid. 
 

 

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. 

Open the door on each lift unit. The door is held in place 

by a latch on the right side

2. 

Station a person at each lift unit

 

 

                                                                         

CML Series  |  28  |  en

 

 

2. 

Station a person at each lift unit

 

2. 

Each person  must  one at  a  time  hold  the  manual 
raise/lower toggle switch down (Fig. 17). No motion 
should occur yet. If a lift unit lowers, release all 
manual raise/lower toggle  switches, then  verify  all 
needle valves are closed (i.e., turned completely 
clockwise)

3. 

Each person should slowly open the needle valve 
located on  the power unit  to  begin descent while 
holding manual raise/lower toggle switch down (Fig. 
17)

5. 

Coordinate the rate of lowering by adjusting the needle
 

valve—counterclockwise  is FASTER  and 

clockwise is SLOWER

Be sure to close all needle valves prior to the next use

 

If one or more lift unit(s) does not move down initially, it 
may be resting on the down stop catch pawl. Fully close 
the needle valve and slightly raise the carriage to clear the 
down stop catch pawl. The carriage is manually raised by 
pushing and holding the manual raise push button while 
also pushing up on the manual raise/lower toggle switch. 
Once carriage is  clear of  the down stop  catch pawl, 
lowering can resume
