The factory setting for the torque adjusting sleeve is at maximum torque. In this state, the first (closest to
the tap) torque reference line will be barely visible. This setting provides a large safety factor against tap
breakage and should not be changed unless low tensile materials are being tapped.

When tapping soft materials, particularly with small taps, it is advisable to use less torque to prevent thread
distortion when tap bottoms.

To adjust the torque, loosen the torque lock screw and rotate the torque adjusting sleeve to its upper limit.
All three torque reference lines will be visible. Take a test cut. If the tap does not cut, increase the torque by
turing the adjusting sleeve. When the proper setting is reached and there is enough torque pressure, turn the
torque adjusting ring another 1/8 turn and secure the lock screw. Always adjust the torque to coarse pitch
when using more than one tap in the same tapping head.
