7. Turn the release valve knob clockwise. Pump the
handle until the punch is completely through the
material. If the hole is not completed, check the
setup described in steps 4 and 5.
Do not operate the pump lever after the ram motion
stops. Continuing to operate the pump lever after
the ram motion stops will damage the driver and
could propel internal parts with great force, striking
nearby personnel.
Note: If the ram motion stops before the hole is
complete, verify that the setup is correct and
that you have not exceeded the tool's capacity.
