Case 2: Vertical mounting position test with
additional weight force suspended
1. Place the piston rod in the retracted end
position.
2. Vent the port 2. The clamp is active.
3. Pressurise the cylinder in extending direc
tion at the test pressure P
with piston area A for extending direction
per Fig. 30).
