OPERATION ADVICE
• Rotate the drive nut to drive the jaws apart to match the length of the spring and to compress as many windings as possible.
See below.
• Make sure the spring is clean where the jaws are mounted on the windings.
• Preload compressor by turning the hand wheel until the jaws has a firm grip on the spring. See figure J.
• Compress the spring by rotating the drive nut using a socket wrench. It is also possible to us an air wrench.
(Limit torque to 120 Nm, in order not to overload the safety pin).
• Do not continue to drive when the upper or lower travel ends of spring compressor are reached.
• When the spring has been safely compressed, remove the top bearing of the strut.
• Before removing the bearing recheck that the spring is still firmly seated in the jaws. See figure K.
