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 operat-
ing condition.
Leak Test
External Leakage
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 Leakage
1. Disconnect the extension side hose.
2. Apply test pressure to the retraction side for 3
minutes.
3. Measure the amount of oil that has leaked from
the extension side.
• The amount of leakage should be 1 cm
3
/3min
or less.
Bleeding Air from the Hydraulic Cylinder
Bleed the air out of the cylinder when the cylinder
is removed or when the hydraulic piping, etc. is dis-
connected.
1. Start the engine and let it idle for approximately
5 minutes.
2. With the engine running at slow speed, extend
and retract the cylinder 4 or 5 times.
• Move the piston rod to a position 100 mm
before the end of the stroke, being careful not
to apply any relief at all.
3. With the engine at top speed, repeat the opera-
tion in (2), then with the engine running at slow
speed, move the piston rod to the stroke end and
apply relief.
