All the electrical equipment is housed in the box situated at the rear side of the headstock.
The AC motor is supplied already installed. The shock-proof plug can be connected directly via a
shock-proof socket to the 220 V mains supply.
All 230V machines are fitted with a master switch with undervoltage release, i.e. this switch must
be switched on before the machine can be switched on via the reserving switch. The master switch
must also be switched on again following a power failure.
If you wish to change the direction of turn of the motor with a reversing switch then in the case of
Electronic Lathe 10600 the reversing switch must remain in the O position for about one second so
that the relay on the control platina has enough time to switch over.
Before connecting the machine to the mains supply you must check the earth.

Change of speed
The rotational speed of the work spindle can be infiniely varied between 45 and 2.300 rpm using
the potentiometer on the front of the machine.
The drive belt must be relocated if the lower speed stage with a minimum speed of 45 rpm is re-
quired.
Please proceed as follows (see headstock):
Remove the protective hood and slacken the drive belts. To do this, slacken nut and screw. Turn
back toothed belt pulley (23) so that drive belt can be let down with no problem on to the different
wheel transmission (12 and 23).
To tighten the belts, tighten toothed belt pulley (53) until the belts on the discs do not slip.
Tighten nut (26) again.
9.2.4
Speed transmission from main spindle to leadscrew
The gearwheel (11) on the main spindle drives the take-up gearwheels (32) on the tumbler gear.
On the centre of rotation of the tumbler gear there is a gearwheel (40) with a toothed belt wheel
(41). The gearwheel is driven by the take-up gears and the toothed belt wheel takes over the drive
of the gear combination on the change-over cutter.
