6.2.2 THE FINE ADJUSTMENT OF THE OUTLET DIAMETER
¨
NOTE! When adjusting the outlet diameter, extend the forming pins first.
Each T-DRILL head is adjusted at the factory to correspond to the nominal size stamped
on the cover of each T-DRILL head. Changing the tube sizes may require adjustment of
the T-DRILL head.
To extend the forming pins (1) press the cover (2) in direction of the shank. Twist the
shank (3) at the same time clockwise until a positive stop is reached, and the forming pins
extend.
T
Check the forming pin span diameter “T” with an adjusting ring or slide gauge.
Depending on the size of the T-DRILL head, the forming pin span T should be 0.020” –
0.055” (0,5 - 1,4mm) bigger than the branch pipe outer diameter (O.D.)
