For Parker PDF models that do not feature a tremolo system: 
 
String height is always adjusted by raising and lowering the bridge- never by adjusting the neck’s truss rod.  Adjusting the truss rod is only for fixing the pitch of the neck 
(or forward/back bow of the neck) 
Adjustments for string height are made from the front of the guitar, on the bridge located behind the pick-ups.  Intonation adjustments are also made via the bridge on the 
front side of the guitar.  
 
 
 
 
 
 
 
 
 
 
 
 
A. Bass side height adjustment screw - turn clockwise to lower this part of 
the bridge, turn counter clockwise raise this part of the bridge. 
             
B. Treble side height adjustment screw- turn clockwise to lower this part 
of the bridge, turn counter-clockwise to raise this part of the bridge.

** Remember!  Minor adjustments are key- make sure to raise and lower 
the bridge evenly, one turn at a time per side.
