Torque Arm

The K-40/K-40B is supplied with a torque arm inside
the inner drum (Figure 21) and attached to the back
end of the cable (Figure 22).
The torque arm retains the cable inside the inner drum of
the K-40/K-40B and greatly enhances the performance of
the machine. It is adjustable to different sizes of cable
ranging from / " through

Cable End Indicator

The C-13-IC SB Cable has a "speedbump" at the back
end of the cable (Figure 23). This bump in the cable will
warn you to stop feeding cable out of the drum. The
"speedbump" is most effective on K-40 units with the
autofeed accessory. The bump will not pass through the
autofeed during operation of the machine. To pass the
bump through the autofeed, lift the actuator handle.
Continuing to feed the cable past the speedbump may re-
sult in the cable coming out of the inner drum requiring
you to reload the cable.
