7.13B INSTALLING THE URETHANE STRIPPER
& PUNCH & DIE
REFER TO FIGURE 28.
1. Raise the top limit switch to its highest position. Power the machine and let the punch ram retract
to its full UP position.
2. Open the standard stripper and remove it from the machine by removing the left hand mounting
bolt.
3. If there is a punch and die installed in the machine, remove them.
4. Remove the two bolts holding the die holder and remove the spacer plate from under the die
holder. Replace the die holder bolts with the shorter bolts (F) provided with the urethane stripper.
Do not tighten the bolts yet.
5. Remove the punch holder (B) from the end of the ram.
6. Disassemble the urethane stripper by removing the two retaining nuts (I).
7. Install the stripper mounting plate (A) and the punch holder (B) to the ram, with the bolts
provided.
8. Select the proper punch and die. Make sure that there is proper clearance between the punch and
die. For recommended clearances, SEE LETTER G ON PAGE 27.
9. Clean both the punch and die of any foreign material.
10. Insert the proper die in the die insert (J). (If the die has a flat spot in it, align this with the bolt in
the die insert.) Tighten the bolt firmly with a wrench.
11. Insert the punch into the punch retaining nut. Make sure that it seats properly. Place the punch
retaining nut assembly on the die insert (J), with the punch inserted in the die.
NOTE: IF YOU ARE USING PUNCHES THAT REQUIRE A KEY, INSERT THE KEY IN THE
PUNCH AT THIS POINT.
12. Place the disconnect switch in the ON position and the selector switch in the START position.
Power the machine by pressing the green START button.
13. Check to make sure that there are no objects (such as tools) under or on any of the moving parts.
14. Place the selector switch in the JOG position and carefully inch the cylinder ram to its set DOWN
position.
15. Turn the machine's power OFF.
16. Lift the punch retaining nut and turn it on to the punch ram. (The die holder may have to be
moved slightly to align the punch retaining nut to the punch ram.) When using keyed punches,
after you start the nut on the ram, raise the punch and rotate it until the key seats in the punch
ram.
17. Use a wrench to tighten the punch retaining nut. Make sure that there is equal clearance on all
sides of the punch in the die.
18. Re-tighten the bolts (F) in the die holder.
19. Check to be sure of proper alignment. Realign, if necessary.
20. Power the machine and raise the ram to the top of its stroke and turn the machine OFF.
