Running operation
Only use chucks recommended by Holzmann Maschinen.
The maximum spindle speed for the Ø320 mm diameter face plate should not exceed 1255 min
When threading or automatic feed is not in use, the selector lever feed direction should be in the
neutral position to ensure disconnection of the lead screw and the feed screw. To avoid
unnecessary wear, the thread dial indicator should not be connected to the lead screw.

Threads and feeds
18.5.1
Change gear gearbox
For optimum adaptation to the respective requirements for threading, the change-gear gearbox
must be set according to the data scale. A large number of feeds and most thread pitches can be
set with the factory fitted change gears. For special feeds or thread pitches, the required change
gears must be changed.
Switch off the machine before replacing or changing the position of the change
wheels and secure it against unauthorised or unintentional recommissioning.
The change gears for the feed are mounted on a change gear shear or directly on the lead screw
and the feed gear.
In order to obtain the desired thread according to the table, the corresponding gearwheel
combinations must be mounted beforehand:

The shift lever for the direction of rotation (1) is used to shift the
machine.
If you put the switch down, the jaw chuck runs counterclockwise.
If you place the switch upwards, the jaw chuck runs clockwise.
WARNING
1.
Disconnect the machine from the power source
and secure it against unintentional start-up.
2.
Loose the screws (1) and remove the cover on
the left side of the headstock.
3.
Loosen the hexagon nuts (2) and the Allen screw
(5) and move the swing frame (3) out of the way.
4.
Change the gear wheels (4) according to the
feed or thread table.
5.
Position the swing frame so that the large gear
wheel meshes with the smaller gear wheels.
Then tighten. Make sure that there is a clearance
of 0.005 - 0.007 mm between the gears.
(Adjusting the gears too tightly will result in
excessive noise and increased wear.)
6.
Remount the cover (pay attention to the
position switch!) and reconnect the machine to
the power source.
