7.9 PICKET TOOL INSTALLATION & OPERATION
This tool mounts in the punch station only. REFER TO THE DRAWING ON THE FOLLOWING
PAGE. The machine must be in the PUNCH position to operate this tool. Remove the die holder,
stripper and the punch retaining nut. Install the tool so that the punch ram aligns with the ram on the
picket tool and anchor it to the punch bolster with the finger clamps (C) provided. The maximum tube
size is 1 inch, 16 gauge, square tube.
CAUTION: THE DOWNSTROKE OF THE MACHINE MUST BE SET BEFORE OPERATION
OF THE TOOL. FAILURE TO SET THE DOWNSTROKE OF THE MACHINE WILL
RESULT IN DAMAGE TO THE TOOL.
1. Set the down stroke of the machine so that the upper die clears the lower die by twice the wall
thickness of the tube, plus 1/32 of an inch (.8mm).
2. Adjust the tube stop (A) just low enough to contact the upper edge of the tube.
3. Adjust the rest stop (B) so that it is approximately half of the tube size below the lower die.
4. Feed the tube into the tool until it contacts the stop (A). Depress the foot pedal.
5. Make sure that the slugs eject from the tool as the next piece is fed into the tool.
6. Lubricate the dies every 10-15 cuts and grease the ram daily.
CAUTION: ALWAYS REMOVE THIS TOOL WHEN IT IS NOT IN USE!
