1.
Maximal opening of the flange spreader may be enlarged when it is used together with an
additional step block (see Fig. 5).
2.
The wedge is returned to its initial position by relieving pressure with the screw 8 (Fig. 1)
situated on the body of the hydraulic cylinder.
3.
Clean the spreader from contaminants and place it in the case when the work is finished.
CO-UTILIZATION OF WEDGE MECHANISMS
Co-utilization of two hydraulic wedges allows to achieve even flange spreading. Wedges should
form a flat angle (180°) in relation to flanges circumference.
Two hydraulic wedges can be used concurrently in combination with a hand-operated pump, a
double-flow collector and a hydraulic hose (see Fig.
6)
