DISASSEMBLY AND ASSEMBLY
WARNING
• Be sure to release the residual pressure from the hy-
draulic hose before disconnecting it.
• When adjusting the pin hole position, never put your
finger into the hole.
Important:
• When tightening the lock bolt with a double nut, al-
low
a clearance of 0.5 to 1.0 mm between the nut
and the lock collar.
• When assembling, adjust the pin-connecting area
with a shim so that no clearance is left. Be sure to
reduce the clearance until a 0.2-mm-thick-shim can-
not be inserted by hand.
• Be sure to bleed the air from the cylinder before
starting for the first time after reassembling hydrau-
lic
devices such as the hydraulic cylinder or hydrau-
lic piping.
