3. Replace all worn or damaged seals. No special tools are required. If replacement of diaphragm seal (P/N 880417) is
necessary, follow the installation diagram. Lubricate all seals and cylinder walls with hydraulic fluid MIL-PRF-5606 or
approved equivalent.
4. When necessary to disassemble the jack:
a. Replace all defective parts.

with a brass rod cupped at one end.
e. Should any malfunction occur in the velocity fuse, return to factory for repair or replacement.
