Tubenut Head Operation
When using a Tubenut head, a special function is required to re-align the socket after normal fastening
operations and allow the socket to be placed onto the nut to be fastened. The start trigger must be held
“ON” for the complete fastening of the part. If the trigger is released during the fastening cycle, the
fastening will stop. The fastening can be re-started by simply squeezing the trigger again. Use the
procedures below to re-align the Tubenut socket.

proper operation), the Gear Head Selection is wrong ([SYS], [D-No]-036).
