PNEUMATIC NOTCHING TOOL OPERATIONS´ MANUAL
Removal and Reshaping of the Cutters:
With regular use the cutters have a long live. But if the notches do not show sharp edges anymore, the
function of the notches is no more guaranteed and the cutters should be changed or re-sharpened.
To remove the upper cutter, just unscrew the flat headed screw and take off the cutter. If it is only slightly
damaged, it can be reshaped. But if it is severely damaged, it must be replaced.
To remove the lower cutter, unscrew both straight pins and take off the cutter. The backing plate in the back
should not be removed. It normally does not wear out and must not be reshaped.
The lower cutter may be turned four times. It can be easily reshaped with a surface grinding machine.
Care should be taken when reinstalling the cutters, making sure that there is no dirt between cutter and
bearing surface.
Hydraulic Oil Refill:
An air cushion may occur in the hydraulic system after some time, because of slight leakage at the seals.
This is the case when the notching tool does not close completely. In order to refill the hydraulic oil from the
oil bottle which is enclosed, take off the compressed-air supply. Then hold the tool in a horizontal position
and take off the screw plug (40). Fill the hydraulic oil in the bore hole until it appears in the opening. You
can now reinstall the screw and continue to work.
