CHAPTER 3 - SETTING UP YOUR EDLUND CROWN PUNCH CAN OPENER
This chapter covers the procedures for setting up your new EDLUND CROWN PUNCH CAN OPENER. You may
find it helpful to review the Controls and Features in (Figure 2 on page 7).
Setup and Operation of the EDLUND CROWN CAN OPENER
1. Unpack the crown punch machine. Check for any loose hardware or damage.
2. Before operation, your new crown punch machine should be sanitized. This will involve removal of the
tooling for sanitation and wash down of the machine. Review the Cleaning instructions on page 10.
3. Insure the "T" handles are tight. They are located behind the head of the crown punch machine. The height,
with the guard ring in place, must be such that when a can is in position under the crown punch, from the
can seam to the lip of the guard ring is approximately 1/8 (3,2mm) to 3/16 (4,8mm), (Figure 3
On page 8).
4. Before starting, always inspect your tooling. The crown punch must be free of nicks, burrs, dents or bent
points. The shearing surface must be dull. The guard ring must seat perfectly on the seam of the can being
opened. The retaining clip must be flat and not deformed.
5. Insure the crown punch, guard ring and clip are in place properly. The two knurled screws that hold the
guard ring in place must be tightened with a flathead screwdriver before operation.
6. Insure the splash guard is on before operation.
7. Connect the air line. The air must be clean and dry. This typically requires a drier on the compressor. A 5
micron filter and coalescing filter are recommended inline before the connection to the crown punch air
inlet. The air requirement is 85 psi at 1 to 2 CFM. Note: No additional inline lubrication is required (the
cylinders and air valves are already greased).
8. The crown punch is a one person operation. Place the can under the guard ring and seat it against the back
of the tab that is slightly lower. Use both hands and press the green buttons at the same time (this insures
the operators hands are clear of the opening area). Hold the green buttons in until the can is completely
opened and then release. Never double press the green buttons when opening a can.
9. Remove the opened can with both hands.
10. Carefully remove the lid from the top of the product and discard. Avoid the perimeter seam area. (safety
gloves are recommended).
11. If the side magnet option is on the crown punch machine (625M), operate the two green buttons as
previously explained then move the can under the magnet and raise the can until the magnet snaps the lid
up and holds it. The magnet will retract and drop the lid with the opening of the next can.
(YELLOW)
AVOID THE SHARP EDGES OF THE LID. DO NOT ATTEMPT TO REMOVE THE LID FROM THE MAGNET BY HAND.
NOTE: The crown punch opener is factory adjusted to open a standard #10 can or the particular size can ordered.
The crown punch knife should penetrate the can just far enough to remove the lid but not so far as to cause
excessive splashing of liquid in the can. If a height adjustment is required, see “Adjusting the Head” in
Chapter 4.

CHAPTER 4 - MAINTAINING THE EDLUND CROWN PUNCH CAN OPENER
This chapter covers regular maintenance procedures that will ensure the best performance and long life of your
opener.
Adjusting the Head
BEFORE PERFORMING ANY MAINTENANCE, YOU MUST DISCONNECT THE OPENER FROM THE AIR SUPPLY.
1. Place the can that you want to adjust the machine to below and against the guard ring tab.
2. Loosen the four (4) "T" bolts at the rear of the vertical (Figure 3) and raise or lower the Head as needed,
keeping the can and guard ring aligned and level.
Tip: Placing a 1/8 to 3/16-inch thick shim between the can and guard ring will help.
3. Tighten the four (4) "T" bolts.

Changing Tooling
To open a different size can, you must use the following procedure to change the Crown Punch.
BEFORE PERFORMING ANY MAINTENANCE, YOU MUST DISCONNECT THE OPENER FROM THE AIR SUPPLY.
Tool Needed:
•Flat Head Screwdriver (optional)
1. With one hand, hold up on the guard ring (Figure 3 on page 8) and with the other hand, unscrew the two
(2) Thumbscrews (Figure 3 on page 8).
Tip: You may need a Flat Head Screwdriver to loosen the screws.
USE CAUTION HANDLING THE CROWN PUNCH IN THE NEXT STEP.
2. Let the guard ring down and set it aside. Now hold up on the crown punch with one hand (being careful of
the pointed edges), and with the other hand, pull the retainer clip straight out (Figure 2 on page 7).
Tip: You may have to wiggle the crown punch to loosen the clip.
3. Set the crown punch and retainer clip down with the guard ring.
NOTE: Do not let the crown punch fall on the base.
4. Install the new crown punch, guard ring and retainer clip in the reverse order.
5. If the lid knockout pins do not align with the holes in the crown punch backing plate, rotate the punch or
remove the pins and use the alternate hole locations (can size 400 or smaller).
6. Place the can that you are opening under the guard ring against the tab and adjust the head height
described in “adjusting the head” on page 8.
7. Re-connect the air supply.
8. Operate according to “Using and operation of the EDLUND CROWN PUNCH CAN OPENER" on page 6.

10 Edlund Company CROWN PUNCH CAN OPENER, Models 625M and 625
Crown Punch Cleaning
BEFORE PERFORMING ANY MAINTENANCE, YOU MUST DISCONNECT THE OPENER FROM THE AIR SUPPLY.
Remove the splash guard, crown punch, guard ring, and retainer clip (Figure 3 on page 8) after every use for
cleaning. You may rinse down the entire machine with soap and water to remove any residue from the unit.
USE CAUTION HANDLING THE CROWN PUNCH IN THE NEXT STEP.
1. Remove the tooling per Changing Tooling on page 9.
2. Wash down and sanitize the entire splash zone area and any other areas of the machine that may have
food contamination on it. Foreign material that remains on the machine will dry and create unsanitary
conditions and can affect the performance of the machine. Failure to do so can result in valve and cylinder
damage causing costly repairs.
3. Reassemble the crown punch, guard ring, retainer clip, and the splash guard.
4. Be sure all screws are tight.
5. Reconnect the air supply.
TIP: Cover the air inlet to insure water does not enter the crown punch machine when sanitizing.

CHAPTER 5 - TROUBLESHOOTING
Consult the Troubleshooting Table below for common problems. If you continue to experience problems, call our
Technical Support Representatives at 1-800-772-2126.
Troubleshooting
BEFORE PERFORMING ANY MAINTENANCE, YOU MUST DISCONNECT THE OPENER FROM THE AIR SUPPLY.
A. Drop in pressure or volume of air: 85psi at 2cfm; clean DRY air required. In most cases
this requires a drier on the compressor.
B. Check the air connection. Air should discharge from the unit when disconnected.
C. Inspect the edge of the crown punch, it must be smooth with no dings, chips or
deformations around the entire circular area, this is the crown punches shearing area.
If you should find a slight defect in many cases a light filing can be done, keeping a dull
edge. If damage is extensive replace tooling or return it to the Edlund for re-furbishing.
D. A crown punch must NEVER be sharpened. The typical life cycle of a crown punch can
be as high as 500,000 cycles. At that point, it will need to be re-surfaced. Inspect your
tooling daily for defects and keep the tooling clean.
E. A crown punch is centered with the can by the guard ring. With the guard ring
removed, place your can in the guard ring by placing the can up against the tab of the
guard ring, this is the lower piece welded to the ring itself. The can must fit snug in the
ring with the bottom edge of the ring sitting on top of the can to be opened. Insure
your tooling fits correctly before use.
F. Dented cans should not be opened on your Edlund crown punch. The results of
attempting this could result in tooling or machine damage or the cans failing to open
and getting jammed into the tooling. Should this occur, first remove the air supply and
remove the can from the tooling. Inspect the tooling for damage and mis-alignment
and correct or replace as needed. If cans are consistently dented a slightly smaller
crown punch can be used to help. This method will leave a wider "lip" on the can. EX.
603 can (#10) and guard ring with a 600 crown punch.
G. Operational errors. In order for the can to be opened properly, the can MUST BE
SEATED against the back of the guard ring. Crown punches are designed for high
volume applications and must be used correctly for proper results.
H. It is very important to hold in both green buttons through the entire opening cycle. Do
not release buttons during cycle and then push the button again to finish. This can
result in a "double pump" and can misalign the tooling with the can causing tooling
and or machine damage.
I. If the retaining clip should get worn or bent replace it with a new one.
J. If the mounting studs should become loose or broken (mainly in older machines)
replace them or send back to Edlund for repair.
The crown punch
does not
consistently
open cans.

12 Edlund Company CROWN PUNCH CAN OPENER, Models 625M and 625
K. With a can seated in the guard ring, inspect the gap between the guard ring and the
top of the can seam. See "Setup and Operation", (page 6.)
L. Insure the large pneumatic cylinder is working properly.
M. Should a lid remain attached to the can after operating the crown punch, disconnect
the air supply. First check the spacing between can and guard ring for proper gap. If
this is acceptable, loosen the head of the crown punch with the "T bolts", set the head
so it is level with the can. Re-attach the air supply and open another can.
SERVICE SHOULD ONLY BE PERFORMED BY A QUALIFIED SERVICE
TECHNICIAN.Call our Technical Support Representatives at 1-800-772-2126.
Air is leaking or the crown punch does not
move up or down properly.
