Towing (Hydrostatic Pump Release)
When towing your Articulator, it is necessary to allow the hydraulic fluid to bypass the
hydrostatic pump.
1.
Locate the bypass valve on the top of each pump.
2.
Turn the valves no more than (2) two turns in a counterclockwise motion.
The drive tires should rotate freely.
3.
Tow the unit to the desired destination at a slow speed.
4.
When towing is completed, return the valves to the original position by turning them in a
clockwise motion until they are tight (84-120 in-lbs).
