Tip:
Use the fold-out lever (

)
for additional leverage to unlock the fine feed
lock knob if the knob is too tight. Do not use
the fold-out lever to tighten the knob.

Tip:
Milling with the quill fully extended can
cause tool chatter. For maximum spindle
rigidity, it is better to keep the spindle retract-
ed into the headstock as far as possible with
the quill lock lever and fine feed lock knob
tightened.

(Cutting Speed x 4) / Tool Diameter = RPM
Note:
For carbide cutting tools, double the
cutting speed. These values are a guideline
only. Refer to the
MACHINERY'S HAND-
