Warning: To avoid serious injury and ensure best results for your tapping operaon, please read carefully all
operator and safety instrucons provided for this tapping unit as well as all other safety instrucons that are ap-
plicable, especially those for your machine.
7. Be aware of any other applicable safety instrucons/requirements especially those for your machine.
8. The tapping aachment housing, drive spindle and tap itself can become hot to the touch aer operaon. Use
cauon when removing the aachment from the machine or handling.
Check List For Good Tapping
1. Never use this tapping aachment before reading all safety instrucons for it as well as the machine it is to be
used on.
2. Be sure tap is sharp and of correct design for your applicaon.
3. Be sure tap is in proper alignment with the drilled hole.
4. Be sure the machine speed is correct.
5. Be sure you are following the correct feed rate for the tap based on the pitch of the tap and revoluons per
minute.
6. Make sure the drilled hole is the correct size.
7. Be sure the machine stop is set correctly to avoid hing the boom of a blind hole. See Controlled Depth Tap-
ping.
8. Be sure to allow for sucient chip clearance especially when tapping blind holes.
9. Make sure the work piece is clamped rigidly so that it is not able to move, rotate, or li.
10. Make sure there is enough clearance between the tap and work piece at the starng posion and the retract
posion to be sure the tap is clear of the hole upon retracon. Remember the tapping aachment spindle ex-
tends during reversal out of the hole.
11. Make sure to mount a strong torque bar from the table of the machine, or to the non-rotang quill, to prevent
the stop arm from rotang. The torque bar must be stronger than the largest tap in the tapping aachments
capacity. It must also have a smooth surface so that the stop arm slides freely when feeding in and out of the
hole.
12. Make sure to use the proper cung uid/lubricant for the applicaon.
