Operation 

4.

 

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. 

5.

 

During  the  5  seconds  that  the  Enable  button  is  ON 
(green), push and hold the 

LOWER

 button to lower the 

vehicle.   

6.

 

Release  the 

LOWER

  button  when  the  vehicle  is 

lowered  to  the  floor  and  the  lift  tables  no  longer 
contact the tires. This condition will be indicated when 
the 

STOWED 

indicator turns blue. 

7.

 

Place the vehicle’s transmission in gear (or park) and 
engage the vehicle’s parking or air brake. 

8.

 

Move the lift units away from the work area and turn the 
master  on/off  switch  to  the 

OFF

    

position.  This  will 

ensure  the  lift  units  are  ready  to  be  synchronized  for 
lifting  in  the  future  and  conserve  the  batteries  while 
the lifts are not in use. 

9.

 

Completely  recharge  each  lift  unit  and  the  Touch 
Screen Controller after use. 

8.9

 

Single/paired operation 

In some situations it may be desirable to place only one 
wheel or one axle on stands instead of placing the entire 
vehicle  on  stands.  The  lift  system  features  a  special 
mode  of  operation  called  single/paired  mode  to  allow 
this. The system can be placed in single/paired mode at 
any height. 

1.

 

If  only  one  wheel  of  the  vehicle  will  be  placed  on  a 
stand,  establish  communication  with  the  lift  unit  that 
is positioned on that wheel of the vehicle. If one axle 
will  be  placed  on  stands,  establish  communication 
with one of the lift units on the ends of the axle to be 
supported. 

2.

 

Push  the 

SINGLE/PAIRED

  button  on  the  main 

operation screen shown in Section 8.6. 

3.

 

A  screen  will  appear  asking  whether  the  system  will 
be  operated  in  single  mode  or  paired  mode.  If  only 
one  wheel  will  be  supported  on  stands  push  the 

SINGLE 

button.  If  one  axle  will  be  supported  on 

stands  push  the 

PAIRED

  button.  Pushing  the 

EXIT

 

button will return to the main operation screen. 

4.

 

The  screen  shown  below  (paired  mode  is  shown  in 
this  example,  single  mode  would  be  similar)  will  be 
displayed on the lift unit where single or paired mode 
was  initialized.  All  other  lift  units  will  be  locked  out 
from  operation  and  show  a  screen  indicating  this 
condition. 

 

Fig. 11:  Paired mode operation 

5.

 

All  the  buttons  shown  function  in  the  same  way  as 
described in Section 8.6. The vehicle can be raised or 
lowered  as  needed  to  place  stands  and  support  the 
vehicle.  The  distance  the  vehicle  can  be  raised  or 
lowered is limited while in single or paired mode. 

6.

 

When  all  work  has  been  completed  that  required  the 
wheel/axle to be supported on a stand(s), move the lift 
unit(s) back into position under the wheels. Push and 
release  the 

ENABLE

  button  and  then  within  5 

seconds  push  and  release  the 

AUTO  RETURN

 

button. The lift(s) that was raised or lowered in single 
or  paired  mode  will  automatically  adjust  its  height  to 
match  the  other  units  in  the  system  and  support  the 
vehicle. 

7.

 

Once  the  lift(s)  has  adjusted  its  height  to  match  the 
rest  of  the  system,  all  the  screens  will  return  to  the 
screen  shown  in  Section  8.6.  The  system  will  now 
operate as a whole with all lift units raising or lowering 
together.
