Mechanical Specifications and Installation
4. By hand, gently move the carriage up and down. The carriage should move with little effort within the
play of the loosened screws. If the counterbalance pressure is not high enough, the carriage will hang
from the shipping bracket screws and will be hard to lift. If the counterbalance pressure is too high, the
carriage will push up against the shipping bracket and will be hard to pull down.
a. If the counterbalance pressure seems to low, check the supply pressure to the input fitting prior to
adjusting the factory setting of the regulator. Increase the supply pressure to the fitting until the
pressure gauge on the back of the stage does not show a corresponding increase in pressure.
Check the counterbalance of the carriage again.
b. To adjust the pressure to the cylinders, place one hand on the carriage with the shipping brackets
still loose and slowly turn the regulator knob. Clockwise rotation increases pressure, and
counterclockwise rotation decreases pressure. Adjust the pressure until the carriage mass is
balanced by the cylinders.
5. Once the cylinders are balanced, remove the M5x25mm shipping bracket screws from the end of the
carriage.
6. Remove the shipping bracket from the base (M5x10mm socket head cap screws). Retain the shipping
bracket for future use.
