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.
