2. Basic Information for User of SUA125 NUMERIC Universal Centre Lathe.

2.1. Preface.

This Manual of the SUA 125 NUMERIC centre lathe (hereinafter called Manual) is set up in accordance with “The

Directive 89/392/EEC“ of June 14, 1989 (hereinafter called Directive) which gives basic demands on safe, hygienic and

ecological machinery operation in the states of “European Union“ (hereinafter called EU).

This Directive embodies each machine put on the market in the EU states see Directive, SUPPLEMENT I part 1.1.2

and 1.7.4.

The directive refers in its single chapters to Directives and EU Standards. All these demands are reflected in this Manual.

Note:

According to the Directive, the following EU Standards were used:

A type (basic safety Standards)

B type ( a collection of safety Standards)

B1 engaged in safety points of views (safe distances, etc.)

B2 engaged in safety devices (locking devices, covers, etc.)

C type (safety Standard for machinery - machine tools).

According to the Directive, the following definitions are mentioned in this Manual:

- “dangerous space“ any area inside and about lathe where a person is run to risk of dangering someone

health and safety,

- “exposed person“ person situated in or partly in the area of action where the risk can come into existence,

- “operator“ is a person or persons carrying out an instalation, service, maintenance, cleaning, repairs or lathe

transport.

The EU demands in this Manual are enlarged of ones which are apply to the safety machine operation in the Czech republic.

All demands mentioned in this Manual should be respected by the operator in the interests of safety of operation.

2.2. Form of Manual Arranging.

Instructions for operator, data of maintenance and tests, information of possible lathe out of operation together with

analysis of operational safety conditions are arranged in this Manual by:

- functional and service description

- instructions for the operator (Manual)

- instructions for maintenance carried out daily by the operator for ensuring the operation capacity.

- instructions for ensuring the maintenance by qualified person

- instructions for service ensuring by the manufacturer

- recommended technological turning process

- testing procedure for checking the lathe accuracy

- conditions for installation and mounting

- transport procedure

- instructions for lubrication

- catalogue of spare parts

Instructions and description in this Manual have been set up with the aim of limiting the risk factors to the minimum,

mentioned in the EU Standard - EN 292 "Safety of machine devices".

The survey is tabulated in the following tables.
