Special Procedures
Reverse Operation
Running machine in reverse will cause premature failure
of cable. Use reverse only to free a tool caught in an
obstruction. If this should occur, immediately remove foot
from air foot switch pedal and allow machine to come to a
full and complete stop. Place FOR/OFF/REV switch to
REV (reverse) position.
Tighten screw on nose of machine so that it firmly cap-
tures cable to avoid kinks occurring inside the drum. If
machine has automatic feed, move feed knob to neutral
position. Grasp cable with gloved hands and pull while jog-
ging air foot switch pedal. When tool is dislodged and
drum has stopped rotating, place FOR/OFF/REV switch in
FOR (forward) position, loosen set screw on nose of ma-
chine and follow normal operating procedure.
Never operate this machine in REV (re-
verse) for any other purpose. Operating in reverse can
damage a cable and cause serious injury.
