Tie of to the car if the car is not disabled Which of the following is not a safe standard practice in tying off? See if it will run down by opening the manual lowering valve If a hydraulic elevator will not run down, what is the first thing you should try? In pounds per square inch When calculating hydraulic system pressure, the force is expressed in pounds and the area of the plunger is measured in square inches. How is the pressure expressed? Pascal's Law What is the name of the scientific principle that allows a hydraulic elevator to operate? Every year How often must a static load test be performed?
