When you do so:
1.
Make sure that the shut-off valve on the suction line is completely open before starting the
engine.
2.
Make sure that connections between all hoses and pipes are tight, and that no oil is leaking.
Leaking or otherwise faulty cylinders must be repaired or replaced immediately.
3.
Make sure that all cylinder caps are firmly set and that there are no leaks.
4.
Using a straight edge make sure that cylinder rods are straight.
5.
Lubricate and inspect all cylinders’ mounting points (pins, retaining bolts, etc.).
Detecting Cylinder Internal Leaks
An internal leak is caused by a damaged seal inside the hydraulic cylinder (see #1 in Figure 5
29).
Because the cylinder is leaking oil inside (bypassing), a certain amount of pressure is lost, reducing
the efficiency of the cylinder and its capacity to push and/or pull.
Warning!
Failure to open the shut-off valve may damage the hydraulic system.
