In order to insure smoother operation and longer life of your
hole puncher, the following maintenance should be done
periodically, based on use.
1. Keep the machine clean. To clean the punch piston, turn
on the switch to move the punch piston almost to the
bottom of its stroke. If necessary, cycle the punch
several times to determine where the bottom of the
stroke is, and to correctly position the punch piston.
NOTE:
The internal components of the pump and piston area have very close clearances and are sensitive
to damage from dust, dirt, contamination of the hydraulic fluid or improper handling. The disassembly of the
pump housing requires special tools and training, and should be attempted by a qualified repair person. The
improper servicing of electrical components can lead to conditions that could cause serious injury.
ANY ATTEMPT BY UNAUTHORIZED PERSONNEL TO SERVICE THE INTERNAL COMPONENTS OF
THE PUMP AREA WILL VOID THE WARRANTY.

exposed part of the punch piston.
2. Regularly tighten all fasteners and replace any
worn components.
-3. Check power cord, if cracked or frayed, return the
machine to an authorized repair center for
