1.3 Possible dangers caused by the machineThe tathe has underçone a safety inspecticn (anatysls ot danger with assessment ot rlsks). Ithas been designed and built on the basís of thís aneíysls using the latest technologicalaovsnces.Nonetheless, there remains a residual risk. since the machine operates with
• high revolunons,• rotating parts,• eíectrtcal voltage and currents.
We have used construcãon resources and safety techníques to minlmise the health rlsk to per-sonnel resulting from these hazards,
If the Iathe ís usedand maintained by personnel who are not duly quaíified, there may be a riskresultinq from incorrect operation or unsuitable rnalntenance.
INFORMATION
Ali personnel involved inassembly, commissioning, operation and maintenance must
• be duly qualified,• follow this operatinq manual.
Disconnect the machíne whenever cleaning or maíntenance work ís being carried out.
WARNIN:G!
THE LATHE MAY ONLY SE USED WITH THE SAFETY DEVICES ACTIVATED.

Organise the work area around the lathe ín accordance with local safety regulations.
3.4.3
Pag~2.0
Operatíon, rnaíntensnce and repalr ln the work area must not be hindered.
INFORMATION
The rnains plug of lhe lathe must befreely accesslbte.
Load suspension point
-+ Fasten the load suspension gear around the lathe bed.
-+ Make sure that you distribute the loads evenly 50 that the lathe cannot tum over while ljfting.
-+ Make sure that no add-on pieces or vamíshed parts are damaged due to the load suspen-sion,
InstaUatíon
WARNING!
Danger ofcrushing and overtuming:·The tathe must be installed by at least 2 peopte,
~ Check lhe horizontal orientation of the base of the lathe with a spírit level,-+ Check that the foundation has sufficient fíoor-load capacity and rigidity.
ATTENTION!
Insuffictent rigidity of the foundation leads to the superposítion of vibrations between themachlne and the feundation (natural frequency of components). Insufficient rigidityof theentire lathe .assembtyalsorapídjy causes the lathe to reach critical speeds, with unpleas-ant vlbrations, leading -to bad turnlng-results.
-+ Positíon the lathe on the intended foundation.
~ Secure the lathe to the foundation or substructure of the machine using the (4) throughholes.
O tf necessary, use anü-vlbraton elements (model S1) for your rnacnine substrueture.
INFORMATION
The lnstallation site must be designed in accordance with ergonomic workplace requirements.
The installatlon drawings described below may differ from the real dimensions (cast parts). Thetolerances are in the rangeofthe general tolerances according to DIN 7168 g.
3.5 Firstuse
WARNING!
Personnel and equipment may be endangered if lhe lathe ís first used by inexpsrt psr-sonnel.We do not take Ii'ability for damage caussd by incorrect commissioning.
3.5.1 Cleaning and greasing
-+ Remove the anticorrosíve agent applied to lhe rnachine for transport and storaqe purposes.We recommend the use of stove distillate.
-+ Do not use any solvents, thinners ar other cleaning agents which could corrade the vamishon lhe rnachine, Follow the specifications and indications of the manufacturer of the cleaningagent. •

4 Designand function
The machíne is a universal íaíhe, It has been designedand manufactured forstraight tumingand facing round or reqularly formed three-, síx- or tweíve-square workpieces in metal, plasficsorsimiíar materiais.
lhe hollow work spindle enables you to clamp tonger workpieces with a diameter of up to 25mm.Thespeed is requleted by repositíoning a V-belt Or1pulleys.
The existíng teaoscrew enables longitudinal feed ano thread-cuttlnq, It ís also possíble to usethe machine for drilling jobs with the help of an (optional) drill chuck clarnped ín the tailstock.

4.2 Lathe bedThe íathe bed integrates the headstock and the drivíng unit, for attaching the apron and lead-screw andJoeguiding toe laíhe.saddle.and.tailstock.
4.3 HeadstoekThe bseostock houses the feed gear andthe reducing gear with pulleys. The workspíndle transrníts the torque during thetuming process, The work spíndle alsoreceives the wcrkoíeces and clampínçtoots,
The work spindle Ésdriven an electromo-tor, via pulleys. The replacement of thechanpe gears for oíher feeds is carried outon the headstock.
4.4 Feed gearThe teed, gear is used to select the feedsfor straight tuming as well as for íhread-cutting. ln order to achieve certaín threadpltches, it is necessary to replace thechange gears.
The torque of the work spindle ís transmit-ted to the feed gear and thus to the lead-screw.
4.5 ApronThe apron houses the leadscrew nut withan engaging lever for activating the auto-matic feed as well as the handwheel formanual feed, The straiqht tuming andcross slíde are located on the apron wIthbed guidance.
; 4.6 TallstockThe tailstock ís ueed for centring and drül-ing, supporting long shafts, tumingbetween centres as well as turning long,thin tapers.

Tool height
For the facing process, the cutting edge of the tool must be exactly aligned with the height of thelathe centre to obtain a shoulder~free face. The facing process is a turníng operation in whichthe turning tool feeds perpendicular to the axis of rotation of the workpiece in order to produce aflat surface. The different methods are transversal facing, transversal slicing and longitudinalfacing.
