Installation of the collet chucks

Important!
Never insert the collet chuck alone into the spindle! Always
engage the collet chuck into the nut first! Always ensure
that collet chuck and milling tool have the correct diameter
for proper fit.
Please note: Further collet chuck dimensions are available
as accessory equipment in addition to those collet chucks
supplied. These are listed in our equipment catalogue.
Please consult our customer service department for further
information.

A total of 6 spindle speeds may be adjusted by shifting
the V-belt (Fig. 12 a/b): 280, 540, 780, 910, 1710,
and 2500 rpm.
Tighten belt only lightly! A belt installed too tightly places
excessive loads on the motor and machine mechanical
system!

vice and mount the vice on the work table using the
T-grooves.
3. Adjust desired milling depth.
4. Tighten clamping screws
5. Ensure that the milling tool does not touch the work
piece.
6. Ensure that the proper spindle speed has been adjusted.
7. Switch on milling machine at switch
8. Work using a suitable feed
When milling, always ensure that the feed is against the
cutting direction of the milling tool (Fig. 14).
Always provide feed by hand only! When using the milling
machine in conjunction with the lathe PD 230/E, feed
3 action must not occur via the lathe's automatic feed. Risk
