4. Operation

●

Three-finger Type (GR3SS/GR3SM, GR3LS/GR3LM)

Remove one finger attachment.

Finger attachment

Affixing bolt

●

Two-finger Long-stroke Type (GRST)

Open directions

Finger attachment

Open/close screw

Turn the screw counterclockwise

using a screwdriver.

Affixing bolt

Caution:

• If the gripped work part must be removed while the controller power is cut off, turn the

opening/closing screw or remove the finger attachment on one side to release the work part.

Forcibly pulling the work part out of the fingers may damage the machine.

• Remove the gripped work part if the machine will not be operated for a prolonged period. If the

gripper remains stationary for a prolonged period with a work part gripped, the gripper

performance may drop or its guide function may be negatively affected.
