and relocate to desired location – rearward of slide box 
if moving rearward, or forward of slide box if moving 
forward 

(Figure 20)

slider is moved to final position. 

3.  Lift and pull the QWIK RELEASE

®

 pull arm handle from 

the engaged position

NOTE:

  If your slider is equipped with an air release pin 

mechanism, pull the air release control valve knob 
to disengage the lock pins. 

4.  Visually check to ensure the lock pins are in the disengaged  

position, and that the QWIK RELEASE

®

 pull arm handle is 

locked 

(Notch 2 - Figure 22)

.

 

When lock pins have properly disengaged, proceed to 
Step 6.

 

If lock pins fail to disengage, proceed to Step 5. 

5.  If the QWIK RELEASE

®

 pull handle is in the notch 2 

position but the lock pins fail to retract and are still  
in the engaged position, the QWIK RELEASE

®

 pull  

arm is in an armed, ready to unlock position.

Failure to verify the area is clear of 
others before moving the vehicle could 
result in death or serious injury.

 

b.   Gently rock the tractor and trailer fore and aft while 

listening for the lock pins to disengage. 

 

c.   After the “metallic clang” of the lock pins disengaging  

is heard, reset the tractor brakes, and visually verify 
that the lock pins have been properly disengaged.

If pins DO NOT disengage:
 

d.   Put air pressure back to the trailer emergency brakes.
