Assemble piping after completely removing the dust inside the pipe.
Add a filter into the pressure supplying line.
・Failure to do so could cause oil leakage
and may result in a fire.
・Maintain the function of the incorporated
lock valve and relief valve, and prevent
seizing due to foreign matter.
・If the function of the lock valve lowers, this
is dangerous as the work will fly out when
the hydraulic pressure suddenly lowers
due to blackout or malfunction of the hy-
draulic pump, etc.
・If the function of the relief valve lowers, the
volume of the filled hydraulic oil changes
causing an increase in pressure, which is
dangerous resulting in malfunction.
・If seizing is caused by foreign matter, the
gripping force of the chuck will lower,
which is dangerous as the work will fly out.
Do not attach the other than parts manufactured by Kitagawa Iron Works
to the cylinder. (Refer to pages 5-6, Fig.3-4)

Do not operate the machine wearing gloves,
a necktie, and other loose
clothing or jewelry.
Do not operate the machine after
drinking alcohol or
taking medication.
・Dangerous since
these lead to op-
eration mistakes
and misjudgment.
・Doing so may damage the cylinder and cause oil leakage which could result in a fire. And if the
hydraulic oil leaks, the gripping force of the chuck will lower and the work may fly out, which is
dangerous.
