Operation - Greenlee Quick Draw 90 7906SB Instruction Manual

Operation

The 1/2" conduit-size punch is often used to increase
the size of the pilot hole; this is called "step-up punch-
ing". After enlarging the pilot hole, the 3/4" draw stud is
used to punch the final hole. See steps 1-6.
1. Drill 1/2" pilot hole using a Greenlee Kwik-Stepper
step bit.
2. Turn the release valve counterclockwise to make
sure the ram is fully extended. Install 3/8" draw
stud, 3/4" x 3/8" adapter, spacer and 1/2" conduit
die and insert into pilot hole.
3. Thread 1/2" conduit punch onto draw stud until the
punch is tight. Make sure the draw stud threads are
fully engaged in the punch.
