Pulling/pushing load, rotatable
If the rotating unit is positioned such that the piston rod points down, it is considered a hanging load. The
load pulls on the piston rod. This pulling load acts upon the surface of the piston ring. This leads to the
build-up of pressure in the respective cylinder chamber.
If the rotating unit is positioned such that the piston rod points up, it is considered a standing load. The load
presses against the piston rod. The load is supported by the entire surface of the piston and results in
pressure build-up.
The degree to which pressure build up is affected varies depending on the size of the piston surface.
Do not operate without the cover.
Do not operate in the horizontal position.
Hold the rotatable load component securely in your hand until the locking pin snaps into place.
