General Maintenance
Adjusting the Bottom Knife Left or Right
To adjust the bottom knife left or right:
1
Loosen the bottom knife holder screw. The knife holder on this flange
machine is spring-loaded and will automatically move to the right until it
contacts the top knife.
2
While the knife holder screw is loose, manually place a slight amount of
pressure on the bottom knife holder to keep it against the top knife.
3
Maintain this pressure against the top knife and tighten the knife holder
screw.
Adjusting the Top Knife Left or Right
To adjust the top knife left or right:
1
Rotate the handwheel until the knife is in its highest position.
2
Loosen the top knife screw and move the top knife holder as far left as
possible without interference with the presser foot.
3
Check for interference by manually moving the presser foot up and down.
The motion should not cause interference with the top knife holder.
4
When the setting is correct, tighten the top knife screw.
Checking the Setting of the Knives
After you have followed the preceding steps, check the knives to verify that they
function together properly. To do this:
1
Take a small piece of thread and place it between the two knives.
2
Position the thread so that it rests near the fronts of the knives.
3
Rotate the handwheel and verify that the knives cut the thread. If the knives
cut the thread, they are properly set.
Replacing the Knives
The PFM-4000 Flange Machine has a top knife and a bottom knife. These are
included in the spare parts kit. Read the following paragraphs carefully to ensure
that the knives function together properly after replacement.
WARNING:
Use extreme caution when handling knives. The blades are
extremely sharp. When handling knives, always wear cut-
resistant gloves.
