OPERATING INSTRUCTIONS:
1. Ensure the part to be tapped is secured and sitting flat on
the same flat surface as the tapping arm is mounted.
2. Select the correct tap holder for the tap size required.
Insert the tap into the holder by depressing the locking
ring. Seat the tap square into the tap holder. Release the
locking ring (see Figure 1).
3. Push up the quick-change chuck’s collar to insert the tap holder.
When inserting the tap holder in the quick-change chuck, turn the
holder to align the ears of the holder to the drive slots in the quick-
change chuck. Push up to lock the holder in the chuck (see Figure 2).
4. Position the tap over the hole to be tapped.
5. When tapping through holes, remember that the tap will protrude
through the bottom side of the work piece. Ensure there is sufficient
clearance below the workpiece to allow the tap to extend below the
bottom surface of the part and not hit the work surface.
6. Use a torque style tap holder when tapping blind or bottom holes.
The built in safety clutch on the torque holders will rachet and stop the tap from turning when the tap
reaches the bottom of the hole.
7. Actuate the motor by depressing the lower button and gently guide the tap into the hole. Exert only
enough downward pressure to start the tap in the hole. Once started, the tap pull itself through the
hole.
Do not push or pull on the motor when the tap is engaged in the hole and completing the tapping
process. This will result in poor thread quality, oversized threads, and broken taps.
8. When the hole is tapped (the torque holder rachets for blind holes or the tap extends past the bottom
of through holes) release the lower button and depress the upper button to reverse the rotation of the
motor and remove the tap from the hole.
9. To change tap holders, release the tap holder by pulling up on the quick-change chuck collar and
pulling the tap holder out of the quick-change chuck.
