3 Safety warnings (warning notes)

3.1 Classification of hazards

30 / 11 / 2007

We classify the safety warnings into various levels. The table below gives an overview of theclassification of symbols (pictograms) and warnings for the specific danger and its (possible)consequences.

Pictogram Alarm expres-sion Definition/Consequences

DANGER! Imminent danger that will cause serious injury or death to personnel.

WARNING! Risk: A danger that might cause serious injury or death to personnel.

CAUTION! Danger or unsafe procedure that might cause injury to personnel or damage to property.

ATTENTION!

Situation that could cause damage to the machine and product and other types of damage.No risk of injury to personnel.

INFORMATION

Application tips and other important or useful information and notes.No dangerous or harmful consequences for personnel or objects.

In the case of specific dangers, we replace the pictogram by

or

General dan-ger

with a warning of

injuries to hands,

hazardous electrical volt-age,

rotating parts.

3.2 Proper use

WARNING!

In the event of improper use of the add-on pieces• will endanger personnel,• will endanger the machine and other material property of the operator,• may affect proper operation of the machine.The add-on pieces as conversion kit are provided for the computer-aided - CNC, ComputerisedNumerical Control - milling operations of your machine.

The drive of the step motors may also be performed manually with a control unit (potentiome-ter).

Improperuse!

The milling machine with the adapter kit must only be placed and operated in dry and ventilatedrooms.

The handwheels need to be disassembled.

If the adapter kit is used in any way other than described above, modified without the authorisa-tion of Optimum Maschinen Germany GmbH or operated with different process data, then it isbeing used improperly.

We do not take any liability for damages caused by improper use.

We would like to stress that any modifications to the construction, or technical or technologicalmodifications that have not been authorised by Optimum Maschinen Germany GmbH will alsorender the guarantee null and void.

• Means of shaft lock-down device "Loctite 601, join the shaft"• The designation of parts in the assembly description corresponds to the numbering of the

packing list.• In order to degrease the shaft, a cleaner for brakes or a corresponding cleaning agent is

required.• A tenacious grease e.g. Mobilux 2 or a corresponding lubrication grease serves to grease the

bearings.• Lubricating oil for threading.• Required tools: reamers 6 H7; twist drill 5mm, 5,8mm and 6,5mm; • Countersink; plastic tip hammer; prick punch and scriber;• A set of Allan keys; fork wrench; screw driver;• Tongs and stripping tongs; cutter; screw tap M6;• Manual drilling machine; shifting square; box wrench 13mm; chipping spanner• Soldering iron; small chisel ; abrasive cloth; metal cutting saw
