1.
Disconnect the rod end clevis of all cylinders in a circuit and block up cylinders so the rod can completely extend and retract without
contacting any other components.
2.
Pressurize the system and maintain system at full pressure for at least 5 seconds after cylinder rods stop moving. Check that all
cylinders have fully extended or retracted.
3.
Check hydraulic reservoir and refill as needed.
4.
Pressurize system again to reverse the motion of step 2. Maintain pressure on system for at least 5 seconds after cylinder rods stop
moving. Check that cylinders have fully extended or retracted.
5.
Check for hydraulic leaks using cardboard or wood.
6.
Repeat steps 2, 3, 4 and 5 (3 to 4 times).
