5.3 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:
EVERY 500 HOURS OR SIX MONTHS:
A.) Check the tolerance between the punch ram and the punch ram bushing. To check the tolerances,
remove the punch ram and the bushing from the machine. For parts identification, SEE FIGURE
7 ON THE FOLLOWING PAGE.
1. To remove the punch ram (F) and bushing, cycle the machine until the lower punch pin (A) aligns
with the access hole in the frame. Turn the machine’s power off.
2. Remove the two mounting bolts (B) from the stroke control mounting plate (C) and remove the
stroke control assembly.
3. Remove the die holder and block up the punch ram.
4. Remove the snap ring retainers from the lower punch pin and remove the four mounting bolts (D)
and the grease bolt (E) from the punch ram bushing.
5. Remove the punch ram and the bushing. Care should be taken when removing these parts.
THEY ARE HEAVY!
6. Clean all grease and dirt off both parts and check the clearance between the outside diameter of
the punch ram and the inside diameter of the punch ram bushing. If the clearance between the
two parts is five thousandths (.005) of an inch or more, replace both parts. Reassemble parts in
reverse order.
B.) Check the condition of the cutting blades on the bar shear, angle shear and any other component
tool.
2. EVERY 1,000 HOURS OR ONCE A YEAR:
A.) Check the condition of the bushing in the upper arm and shear arm. This can be done by visually
watching the arms for vertical movement while the machine is in operation. If vertical movement
is noted, block or support the arms with a lifting device and remove the pin and check the
clearance. If the clearance between the pin and the bushing exceeds twelve (.012) thousandths of
an inch (.3mm), replace the bushing.
Since the 9012-24M can be used for a wide variety of applications with many optional tools, it may
be necessary to include additional items in a scheduled maintenance program.
If you have questions about other applications, contact your local dealer or the factory.
