counterclockwise away from the operator. To
unlock the carriage.

O.) CARRIAGE CLUTCHES

The carriage clutches are made of a friction
type material, designed to slip when slide or
carriage engages a feed stop. The clutches are
a spring-loaded arrangement and can not be
adjusted for more pulling power. If clutch slips
under a cut, it is a sign of improper tool grinding,
dull tool or excessive feed. The friction clutches
have sufficient power to handle all work. When
the machine contacts a feed "stop", it is
intended for the clutch to slip, To operate
clutches as shown in (Figure 25), raise handle
"H" (Figure 25) is approx. 20degress above
horizontal, the clutch will engage, Push down
the handle "H" (Figure 25), the clutch will
release. When the carriage lead screw is
engaged for threading the carriage feed clutch
is mechanically interlocked (can not be
engaged). This is to prevent machine damage.
