5.2 SCHEDULED MAINTENANCE
A program of scheduled maintenance should be set up and documented according to your application
and the frequency you use this machine. The following is a list of important items that should be included
in a scheduled maintenance program:
1. EVERY 250 HOURS OR THREE MONTHS:
A. Check the clearance between the punch barrel (A) and the punch barrel guide (B).
FOR PARTS IDENTIFICATION, SEE FIGURE 4 ON THE FOLLOWING PAGE.
TO CHECK THE CLEARANCE:
1. With a punch and die properly installed following the instructions in SECTION 6.1, operate the
machine until the punch enters the die.
2. With the punch in the die, jog the machine with the foot pedal, watching for lateral movement of
the punch in the die.
3. If lateral movement is noted, turn the machine’s power off. Remove the punch barrel (A) and
punch barrel guide (B) from the machine and check the tolerance between the two parts.
4. If the tolerance exceeds three (.003) thousandths of an inch (.07mm), replace both parts.
5. When replacing these parts, do not over tighten the drag link bolts (C & E). The bolts should be
tight enough to restrict the punch barrel from rotating, but not so tight that they won’t allow the
drag links (D) to rotate as the arm travels down.
2. EVERY 500 HOURS OR SIX MONTHS:
A. Check the condition of the blades and any component tools for wear. Replace worn parts
promptly.
