with the feed direction selector (6) then set the feed/thread selector (6) to the left hand
position and position one lever at any of the 1-5 hole, the other at the A-E holes. The
feed rod will rotate. If the selector is pushed upwards, a longitudinal feed can be
obtained. If the selector is pushed down, across feed will be obtained.

The direction of thread cutting is controlled by the feed director (6). By operating the
feed selector handle and the feed/thread selector handle according to the thread pitch,
the leadscrew will rotate. Operate the handle (23) down to engage with the leadscrew
