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 some important items that should be
included in a scheduled maintenance program.
Since this machine can be used for a wide variety of applications with many optional tools, every
user must design and implement a scheduled maintenance program that fits his needs.
1. EVERY 500 HOURS OR SIX MONTHS:
A. Check the tolerance between the punch ram and the punch ram bushing. For parts identification,
SEE FIGURE 10 ON THE FOLLOWING PAGE.
2. TO CHECK THE CLEARANCE BETWEEN THE RAM AND THE BUSHING:
A. Install a punch and die following the method outlined IN SECTION 6.1.
B. Place the run/jog switch in the JOG position. With the punch in the die, jog the machine up and
down several times, watching for any lateral movement of the punch in the die.
C. If any movement is noted, check the mounting bolts in the punch ram bushing. Make sure that
they are tight. Also, check the bolt that runs through the punch ram straps to make sure that it’s
not so tight that the straps are binding on the arm or the punch ram.
D. If there is still lateral movement of the punch in the die, remove the punch ram and the bushing
and check the clearance between the two parts.
E. If the clearance between the two parts is more than five thousandths (.005) of an inch (.12mm),
replace both parts.
3. Check the condition of all cutting blades on the machine and any optional tools.
4. Check the condition of the bushings for the (3) main pins shown in Figure 10. This can be done
visually by watching the beams for vertical movement while the machine is in operation. It is
necessary to remove the front cover to observe the drive beam. If vertical movement is noted,
block or support the beam with a lifting device and remove the main pin and check the clearance.
If the clearance exceeds twelve thousandths (.012) of an inch (.3mm), replace the bushing.
5. EVERY 1,500 HOURS OR 1 YEAR:
A. Change the hydraulic fluid in the reservoir and replace the filter.
For recommended fluids, SEE SECTION 5.1.
