- Calculate the cut length Y
This value is the result of the following formula : Y = X - W
3 - Frame and rod cutting, connection holes

. Fit the frame A / hydraulic unit B / rod C in the cutting block as shown in figure 6, taking care to adjust the
distance Y. Tighten the frame and rod locking screws.
- Use a hacksaw with a blade for cutting steel to cut the rod C (see figure 6) along surface S of the cutting block
(see fig. 6), then cut the frame A along surface T of the cutting block.
- With a ø 7 mm drill, bore 4 connection holes using the guide holes R of the cutting block (see figure 6).
- Remove the { frame / hydraulic unit / rod } assembly from the cutting block and burrs.
