drive thru position. 

2)  Center  the  vehicle  between  the  columns  (left  to 

right) in the service bay and position the vehicle’s 
center  of  gravity  at  the  midpoint  between  the 
columns (fore and aft).  NOTE: the center of gravity 
is  based  on  the  weight  distribution  and  is  not  the 
same as the center point of the vehicle.

3)  Position  the  arms  and  adapters  so  all  four  pads 

contact the vehicle simultaneously. 

The vehicle should remain level during lifting

4)  Raise the lift until all four wheels are off the ground.  

Test the stability of the vehicle by attempting to rock 
the vehicle. Check adapters for secure contact with 
vehicle  lift  points.  If  the  vehicle  seems  unstable, 
lower the lift and readjust the arms.  If the vehicle is 
stable,  raise  the  vehicle  to  a  height  a  few  inches 
above the desired working height. 

5)  Lower  the  vehicle  until  the  safety  locks  on  both 

columns engage.  The vehicle should remain level 
when both locks are engaged.  If one side engages 
and the other continues to descend, stop lowering 
the vehicle, raise it several inches, and try again to 
engage both locks. 

Always  lower  lift  into  locks  before  entering  the 
area beneath the vehicle.
