inspection after assembly
No load operation test
1. Place the cylinder in a horizontal position with no load.
2. apply gentle pressure alternately to the ports at both
ends, operating the piston rod 5 or 6 times.
3. make sure there is no abnormality in the operating con-
dition.
Leak test
External leak
1. apply test pressure for 3 minutes each to the retraction
side and the extension side.
2. Make sure there are no abnormalities such as external
leakage or permanent deformation, etc. in the rod seal,
the rod cover mount, or in any welded portion.
Internal leak
1. Disconnect the extension side hose.
2. apply test pressure to the retraction side for 3 min-
utes.
3. measure the amount of oil that has leaked from the
extension side.
• The amount of leakage should be 1 mL (0.034 fl.oz)
/3 min or less.
Bleeding air from the hydraulic cylinder
bleed the air out of the cylinder when the cylinder is re-
moved or when the hydraulic piping, etc. is disconnected.
1. Start the engine and let it idle for approximately 5 min
-
utes.
2. With the engine running at slow speed, extend and re
-
tract the cylinder 4 or 5 times.
• Move the piston rod to a position 100 mm (3.94 in.)
before the end of the stroke, being careful not to
relieve air.
3. With the engine at top speed, repeat the operation in
(2), then with the engine running at slow speed, move
the piston rod to the stroke end to relieve air.
