Read the pressure gauge (3) while you hold the knob.An adjustable relief valve controls the hydraulic pressure to the screed counterbalance system. The pressure at the rod end of the screed lift cylinders should be 345 kPa (50 psi), when the adjusting screw (1) is turned completely in the counterclockwise direction. The pressure will be indicated on the pressure gauge (3) .Turn the adjusting screw (1) clockwise in order to increase the pressure of the screed counterbalance system. Increase the pressure in 345 kPa (50 psi) increments in order to correct problems with the mat that are caused by the setting of the screed. Check the mat in order to determine that the desired results are being achieved after adjusting pressure of the screed counterbalance system.Note: If the pressure of the screed counterbalance system is increased above 1030 kPa (150 psi) the mat density may be affected.
