comes into contact with it. Pull down
sharply one time.
8. When drilling using a mill/drill machine, it must be remembered that without
care, the drill bit could easily come into contact with the surface of the
table.

drill, otherwise damage to the table and/or drill bit could occur.

post slide, shown in Fig. 7.

drill bit installed, down to the maximum depth
required, and hold in place whilst sliding the
limit device up to meet it. Lock the limit device
in place using its locking lever.
