Paving Applications
Setting Valve Offsets (Raise and Lower) for Paver
1. Run the paver until the hydraulic oil is at normal operating 
temperature before setting the valve offsets.
2. Select Valve Offsets  raise:.
3. Turn the Grade Adjustment Knob counter clockwise, 
decreasing the Valve Offset - raise value until the hydraulic 
cylinder no longer moves. Then slowly rotate the Grade 
Adjustment Knob clockwise until the hydraulic cylinder just 
begins to move up.
4. Repeat step 3 for Valve Offsets  lower:.
Set the Valve Offsets first, before setting any other Performance Menu items.
The offset value on one side of the paver may differ from the offset value on the other side of the paver. You must
verify the offset values before swapping boxes.
Never attempt to use Valve Offsets to compensate for a slower raise or lower speed of your hydraulic valves, as
it causes undershooting or overshooting in Slope Mode and can adversely affect the quality of the mat.
