CAUTIONS WHEN WORKING
1C0BF001
When connecting/disconnecting the hoses or
pipes
• When hydraulic hoses or pipes are connected, tighten
them once to the prescribed torque, then loosen them
slightly and retighten them to the prescribed torque.
a. Tighten the fittings after the installation surfaces fit
snugly together.
b. The above procedures do not apply to fittings with
seal tape.
• Use two spanners, one to tighten/loosen and the other
to secure the mating hose/pipe to ensure that the hose
is not twisted.
• After connecting the hydraulic hoses or pipes, apply
the maximum working pressure five or six times to
check for leakage.
• If high pressure, vibration or shock is applied to a twist-
ed hose, oil leak, hose breakage or damage to the
hose fitting can result.
• Be sure that the hydraulic hoses are not contacting
sharp objects or each other. This could cause surface
flaws on the hoses, resulting in breakage.
Handling of seals
• Clean the grooves for O-rings and remove any burrs.
• Be careful not to twist the O-rings. If twisted, remove it
with your fingertips.
• When inserting, be careful not to damage the seal.
• Handling of the floating seal
a. After removal, wipe all oil off the O-ring and housing
of the floating seal.
b. When assembling, apply a thin coating of gear oil to
the contact surface of the housing.
c. After assembly, turn the seal two or three times to
get it to fit snugly.
• Apply grease to the lip of the oil seal.
a. This is to prevent wear from occurring upon first
start up after assembly.
Pressure adjustment for hydraulic devices
• The pressure for hydraulic devices is adjusted by
Takeuchi Mfg. to optimal conditions before products
are shipped for delivery to the customer. The pressure
will not need to be adjusted again except in products
that undergo disassembly and assembly procedures.
