Important Safety Precautions
Do not allow the rotation speed of the chuck to exceed the maximum allowable
speed limit.
For All Users
・If the rotation speed of the chuck exceeds
the rotation speed limit, this is very
dangerous as the chuck and work will fly
out.
The input force of the chuck (piston thrust, pulling force of the draw pipe) must
not exceed the allowable maximum input force．
For All Users
・Input must match the specification of
the chuck.
・Adjust the hydraulic pressure to the
cylinder so that the input force, which
determines the gripping force of the
chuck, does not exceed.
・Excessive input force can lead to
breakage of the chuck, which is very
dangerous, as the chuck can work
can be damaged and fly out.
If you use the chuck with the inside diameter gripping, input force (hydraulic
pressure) must be 1/2 or less of the allowable maximum input.
For All Users
・The chuck may break and the chuck
or work could fly out.
Failure to follow the safety precautions below will result in
serious injury or death.
DANGER
Failure to follow the safety precautions below will result in
serious injury or death.
DANGER
Be sure cover is attached to periphery of cylinder before
operating machine. (Refer to pages 21-22)
For All Users
・This will prevent the body or clothing from
being caught in the machine.
Prepare the covers that conform
to the following standards.
・ EN953
・ EN ISO13857
・ EN1088
Always tighten the bolts at the specified torque.
(Refer to page 26)
For All Users
・If the torque is insufficient or excessive, the
bolt will break, which is dangerous as the
cylinder or work will fly out.
・Fix the lathe spindle or the cylinder when you
tighten bolts. Your hand could slip and get
injury when you work without fixing the
spindle.
・You must use a torque wrench for torque
control.

Tightening torque is moment of force when
you tighten a bolt. Tightening torque= F×L.

※Since the material of the cylinder is aluminum,
it is 80% of the tightening torque to the bolt
size specified for the hydraulic chuck of our
company.
