Air-driven hydraulic pumps will have an FLR, or filter lubricator regulator. When you hook up air to your hydraulic pump, theres a little nozzle on the bottom of the filter. loosening of a connection through the use of hydraulics. You need a link for every wrench of that size, meaning you might need multiple links for a 2,000 ft. lb. The operator should fully turn off the pump either electric or air on the pendant switch when removing the tool from the bolt. You can change the link by pulling the link pin, then sticking on a differently sized link. When the tool fully stalls out, make sure the operator applies one final advancement of the tool to ensure the bolt is fully torqued to specification before moving onto the next bolt. If it fulfills the requirements, you may select the open type. If calibrated correctly, the hydraulic pump will allow the user to change the torque setting accurately. There are two types of hydraulic torque wrenches: square drive and low profile. Size dictates the maximum torque output that these tools can generate. Even if you press the handle of the hand pump repeatedly, the hand pump starts to suction oil, and the oil intake is much less than normal. Use a hydraulic torque wrench not to exceed the rated load of the equipment, try to avoid the danger of overloading, and use a pressure gauge in the system to display the operating load.
