pump.
Tighten the relief valve completely on the pump.
The arm (retract/extend) and gripper (up/down movement) operating pressure is the same as the
arm valve main relief
adjustments are required for these functions. Only "gripper close" requires proper adjustment to
prevent crushing roller carts. See Adjusting Arm Speed on page 241 to adjust the gripper load sense
relief valve.
See Pressure and Cycle Time Chart - PVG-32 Circuit on page 150 for a complete list of pressure settings
and cycle times for each proportional valve function.
For more information, see Adjusting Pressure on the Proportional Valve on page 143.
To adjust pressure on a 96-gallon gripper, see Adjusting Pressure on 96-Gallon Gripper on page 144.
To adjust pressure on a 300-gallon gripper, see Adjusting High Pressure on 300-Gallon Gripper on
page 145 and Adjusting Low Pressure on 300-Gallon Gripper on page 147.
