275kg INFORMATION If you are unable to rectify an issue using these operating instructions, please contact us for advice: Optimum Maschinen Germany GmbH Dr. Robert-Pfleger-Str. 26 D-96103 Hallstadt Email: info@optimum-maschinen.de Safety instructions (warning notes) 1.2.1 Classification of hazards We classify the safety warnings into different categories. The table below gives an overview of the classification of symbols (ideogram) and the warning signs for each specific danger and its (possible) consequences.
In case of specific dangers, we replace the pictogram with general danger injury to hands, hazardous with a warning of rotating parts. electrical voltage, 1.2.2 Other pictograms Warning: danger of Warning: risk of stumbling! Warning: hot surface! Warning: biological hazard! slipping! Warning: automatic start- Warning tilting danger!
If the drilling machine is used in any way other than described above, modified without the approval of the company Optimum Maschinen Germany GmbH, then the drilling machine is being used improperly.
WARNING! Risk of injury caused by workpieces flying off. Clamp the workpiece in the machine vice. Make sure that the workpiece is firmly clamped in the machine vice resp. that the machine vice is firmly clamped on the machine table. ...
All additional devices installed by the operator have to be equipped with the prescribed safety devices. This is your responsibility being the operating company! Safety devices on page 13 Qualification of personnel 1.6.1 Target group This manual is addressed to the operating companies, ...
Obligations of the operating company train the personnel, Obligations of the operating instruct the personnel in regular intervals (at least once a year) on company - all safety standards that apply to the machine, - the operation, - generally accepted engineering standards. check the personnel‘s knowledge level, ...
Safety measures during operation CAUTION! Risk due to inhaling dusts and mist hazardous to health. Dependent on the material which need to be processed and the used auxiliaries dusts and mist may be caused which might impair you health. Make sure that the generated health hazardous dusts and mist are safely sucked off at the point of origin and is dissipated or filtered from the working area.
1.10 Safety check Check the drilling machine before each start-up or at least once per shift. Inform the person responsible immediately of any damage, defects or changes in the operating function. Check all safety devices at the beginning of each shift (with the machine stopped), ...
WARNING! Dangerous voltage even if the main switch is switched off. The areas marked by the pictogram might contain live parts, even if the main switch is switched off. 1.12 Drilling table Seats for T-slots are attached to the drilling table. WARNING! Risk of injury due to workpieces flying off at high speed.
Personal protective equipment for special works Protect your face and your eyes: Wear a safety helmet with facial protection when performing works where your face and eyes are exposed to hazards. Use protective gloves when handling pieces with sharp edges. Wear safety shoes when you assemble, disassemble or transport heavy components.
1.19 Accident report Inform your supervisors and Optimum Maschinen Germany GmbH immediately in the event of accidents, possible sources of danger and any actions which almost led to an accident (near misses). There are many possible causes for "near misses".

Furthermore, it is possible that the admissible exposure level might be different from country to country due to national regulations. This information about the noise emission should, how- ever, allow the machine operator to evaluate the hazards and risks more easily. CAUTION! Depending on the overall noise exposure and the basic threshold values, machine operators must wear appropriate hearing protection.
Delivery, interdepartmental transport, assembly and commissioning Notes on transport, installation, commissioning Improper transport, installation and commissioning is liable to accidents and can cause damage or malfunctions to the machine for which we do not assume any liability or guarantee. Transport the scope of delivery secured against shifting or tilting with a sufficiently dimen- sioned industrial truck or a crane to the installation site.
Transportation to the installation site ATTENTION! The drilling machine is lifted and transported at the drilling head or at the load suspension points of the packaging using a suitable hoisting device. Make sure that the housing of the pulleys is not getting damaged when suspending the load without packaging.
Installation Check the horizontal orientation of the base of the drilling machine with a spirit level. Check that the foundation has sufficient floor-load capacity and rigidity. Place the drilling machine on the provided underground. Fix the drilling machine in the provided through-holes on the machine foot. WARNING! The condition of the underground and the fixing type of the machine foot to the underground must be in a way that it can bear the loads of the drilling machine.

Risk by using improper tool holders or operating them at inadmissible speeds. Only use the tool holders (e.g. drill chuck) which were delivered with the machine or which are offered as optional equipment by OPTIMUM. Only use tool holders in the intended admissible speed range.
Connect the electrical supply cable. Check the fusing (fuse) of your electrical supply according to the technical instructions regarding the total connected power of the drilling machine. ATTENTION! Imperatively make sure that all 3 phases ( L1, L2, L3) are correctly connected. Most motor defects result of wrong connections.
Operation Safety Commission the machine only under the following conditions: The machine is in proper working order. The machine is used as prescribed. The operating manual is followed. All safety devices are installed and activated. All failures should be eliminated immediately. Stop the machine immediately in the event of any anomaly in operation and make sure it cannot be started up accidentally or without authoriza- tion Notify the person responsible immediately of any modification.
If required, adjust the desired drilling depth by means of the drilling depth stop in order to obtain a uniform drilling depth. Please make sure to use a suitable dust suction when treating wood since wood dust may be health hazardous. Wear a suitable dust mask when performing works at which dust is gener- ated.
