5.9.2 Replacing Master Hold-Down Cylinder
The hold-down is raised and lowered by master and slave single-acting hydraulic cylinders. The master cylinder is located at
the left end of the hold-down.
Cylinder operation is adversely affected by air in the system and by cylinder seal failure. If there is air in the system, refer to
5.9.4 Bleeding Cylinders and Lines, page 303 for instructions on how to bleed the circuit. If the cylinders seals have failed,
replace the cylinders.
