heads comprise the blade guide plates which ensure correct longitudinal align-

coolant supply cocks.
Blade steady buttons
The blade steady buttons prevent upward blade flexure caused by the vertical
action of the cutting force. These buttons are fitted on both the front and rear
heads, and need no adjustment.

blade changes, the plates must be adjusted as follows:
