Do not operate the machine wearing gloves,
a necktie, and other loose
clothing or jewelry.

Important Safety Precautions
Failure to follow the safety precautions below could result in
serious injury or death.
WARNING
Do not modify the chuck in a way not permitted
by the manufacturer.
For All Users
・It may not only break the chuck but the
chuck and the work may fly out, which is
dangerous.
・If you attach a locator or jig on the chuck
body surface, only process work in an
acceptable range (Refer to page 22).
Periodically supply adequate grease (Refer to page 23). Turn off power before
adding grease.
For All Users
・Insufficient grease supply lowers the
gripping force, causes operation failure due
to lower hydraulic pressure, lowers the
gripping precision, and causes abnormal
wearing and seizing, etc.
・This is dangerous as the work could fly out
from a drop in the gripping force.
Do not operate the machine after
drinking alcohol or
taking medication.
For All Users
For All Users
・Dangerous since
these lead to
operation mistakes
and misjudgment.
7
Do not grip a chuck with a chuck.
For All Users
・Because it is easy to confuse the specifications of
each chuck and the protrusion become long and is
apt to raise rotation speed, it is apt to exceed the
specifications of the base chuck. The chuck may
break and the chuck or work could fly out.

※ 1. When storing this product, the product should be subjected to the antirust treatment and stored in a place free from
wetting, condensation, or freeze.
※ 2. After checking a cylinder that is being used, please set the hydraulic pressure.
1.Maximum static gripping force
The static gripping force is the gripping force when the chuck is at a stop.
The power chuck has a mechanism to convert input force (piston thrust force, draw pipe drawing force) from the cylinder to
gripping force. Therefore, the gripping force when the allowable maximum input force becomes the maximum static gripping force.
However, the gripping force is different depending on the state of grease lubrication, grease in use, height of the jaw,
etc. The maximum static gripping force specified in the specification is the value under the following conditions:
・The Kitagawa standard soft jaw is used as the jaw.
・The attaching bolts of the soft jaw are tightened at the
specified torque. (Refer to page 9)
・The numerical values are obtained with the Kitagawa
gripping force meter . The gripping position of the
gripping force meter is at a position 1/2 of the height of
the soft jaw top surface (height from the chuck surface
to the top surface of the jaw).
・CHUCK GREASE PRO is used. (Refer to page 23).
・A variable displacement pump with the discharge
volume of 20 liters/min or more is used as the hydraulic
source. The pressure is set by the pressure control
equipment of the pump itself, or the pressure reduction
valve equipped separately.
