TO CUR CI'STOI"IERS

This operatorrs manual contains all the essential information required for profitable operation and maintenance of your MAHO toolroom machine. These operating insturctions should be handed bo the appropriat,e operating and

maintenanee personnel.

The separate operating instnuctions CNC \32/l}-Grafik, the progranrning instructions CNC 432 and the prograrrning instructions |tGeometric paekagett are part of this operatorfs manual. For specifiec details on the control system, refer only to the operating instruetions CNC tl32/ 104rafik. The machine should only be taken into serviee when the operating and maintenance personnel has carefullv read the operatorrs manual and is fullv conversant with aII its details. Operation and maintenance of the machine should be earried out in with the instructions contained in this operatorts manual.

?

aeeordanee

For any demage resulting from nonobsenrance of these statements or fucm inappropriate procedur.e rf,e assutle no

liability. In the event of faults whieh cannot be rectified with available Iocal resources, the eause of the fault should be preciselv established on the basis of the operatorrs manual before the appropriate MAHO agency or Messrs. MAHO themselves ane contacted.

This operatorrs manual will assist you with solving youn machining problems in an advantageous manner. We are certain that the l4AH0 toolroom maehine will

meet your expectations

The total surfaee area ( q^D4p) equired is (Iength x width) 6 x 4,5 n QT nz). Within the penmlter of this surface area bhe machine overlappEd with an iarea of 9 m' and a minimun bearing capacity of 930 daN/m'(0,93 L/m') must be guaranteed. Ideal is a floor made of eoncret,e or cross cut wooe.

A composite floor area, i.e. piacing the machine partly on conerete and partly on a wooden floor of the above deseription, is not pernissible. Any unevenness of the machine site surface must not exceed 3 nrnlm. No special foundation is required. The machine has to be bolted to the floor without use of damping plates. a) Fixators, whiclr are delivered with the machine, can be only used fot" sefting up the machine. The fixators to be filled in with grout, must be separately ordered. b) A constant r.oom temperature of max. 30o c (303 I() must not be exceded.

CAUTION:

-

Relative atmospherie humidity may be max, 80 %.

NOIE:

A higher relafive atmospherie humiditv or room temperature up to 55" C (328 K) is permissible, provided that MAHO cooling units are being used in the command station and
