Operation - Greenlee Quick Draw 7804SB Manual

Operation

Punch
1. Drill a pilot hole.
2. Turn the release valve knob counterclockwise to fully
extend the ram.
3. Assemble the appropriate die and draw stud
components. Insert into the pilot hole.
4. Thread the punch onto the draw stud until it is tight.
If the punch is not tight, the hole may not be
completed.
5. Close the release valve knob. Pump the lever handle
until the punch is completely through the material.
6. Open the release valve knob. Remove the punch.
Step-up Punching
The 1/2" conduit-size punch is often used to increase the
size of the pilot hole; this is called "step-up punching."
After enlarging the pilot hole, the 3/4" draw stud is used
to punch the final hole.

Do not operate the pump lever after the ram motion
stops. Continuing to operate the pump lever after the
ram motion stops will damage the driver and could
propel internal parts with great force, striking nearby
personnel.
