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. Symbol Alarm expression Definition / consequence...
If the drilling machine is used in any way other than described above, modified without authori- zation of Optimum Maschinen Germany GmbH, then the geared drill is being used improperly. We will not be held liable for any damages resulting from any operation which is not in accord- ance with the intended use.
Operators must be qualified. 1.4.1 Avoiding misuse Use of suitable cutting tools. Adapting the speed setting and feed to the material and workpiece. Clamp workpieces firmly and free of vibration. ATTENTION! The workpiece is always to be fixed by a machine vice, jaw chuck or by another appropriate clamping tool such as for the clamping claws.
be duly qualified and strictly follow these operating instructions. In the event of improper use there may be a risk to personnel, there may be a risk to the machine and other material values, the correct function of the drilling machine may be affected. Always disconnect the drilling machine when cleaning or maintenance work is being carried out.
Safety measures during operation CAUTION! Danger due to inhaling dust and mist that is 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. Ensure that the harmful dust and mist generated are safely sucked off at the point of origin and routed away from the working area or filtered.
Wear safety shoes when you assemble, disassemble or transport heavy components. Use ear protection if the noise level (emission) in the workplace exceeds 80 dB (A). Before starting work make sure that the required personal protective equipment is available at the work place.
1.12 Emergency stop switch CAUTION! The drilling spindle keeps turning for a short time even after actuating the emergency stop switch depending on the preset speed. 1.12.1 Drilling table Seats for T-slots are attached to the clamping table. WARNING! Risk of injury due to workpieces flying off at high speed. Securely fix the workpiece on the drilling table.
1.15 Safety during operation We provide information about the specific dangers when working with and on the drilling machine in the descriptions for these types of work. WARNING! Before activating the drilling machine, double-check that make sure that there are no dangers generated for persons, not cause damage to equipment.
The operator of the machine must ensure that the electrical systems and operating equipment are inspected with regards to their proper condition, namely, by a qualified electrician or under the supervision and direction of a qualified electrician, prior to initial commissioning and after modifications or repairs, prior to recommissioning ...

Delivery, internal transport and commissioning CAUTION! Injuries caused by parts falling over or off a forklift, pallet truck or transport vehicle. Only use means of transport that can carry the total weight and are suitable for it. Notes on transport, installation and commissioning Improper transport of individual devices, unsecured devices stacked on top of each other or next to each other in packed or already unpacked condition is accident-prone and can cause damage or malfunctions for which we do not grant any liability or guarantee.
Assembly WARNING! Danger of crushing when assembling and installing the machine components. The drilling machine must be installed by at least 2 people, because various elements and individual parts have to be sustained and joined during assembly. INFORMATION The following description of the assembly refers to the DDQ32 drilling machine. It was chosen for the description of the following work because of its similarity to the DQ25 drill.

3. Screw the hexagon socket screw with the locking washer into the aluminium profile. Hexagon socket screw WARNING! Locking washer Make sure that the hexagon socket screw and the locking washer are mounted tightly screwed. Otherwise the aluminium profile would slide out of the fixture when the setting screw is screwed off.
3.5.1 Foundation and ground Check the substructure. The substructure must provide adequate load capacity. The substructure must be prepared in such a way as to ensure that, if any lubricant is used, it cannot penetrate the floor. 3.5.2 Fixing In order to provide for the necessary stability of the drilling machine, connect the machine with its foot to the substructure.
OPTIMUM. Only use tool holders in the intended admissible speed range. Tool holders may only be modified in compliance with the recommendation of OPTIMUM or of the manufacturer of the clamping devices. WARNING! There is a danger to persons and equipment, if the first commissioning of the drilling machine is carried out by inexperienced personnel.

Before starting work WARNING! For drilling jobs, it is necessary to clamp the workpiece firmly to prevent the bit catching on the pieces. A machine vice or clamping claws is a suitable clamping device. Before starting work, select the desired speed. It is depending on the used drilling diameter and on the material.
Disconnect the machine from the electrical supply. Pull out the mains plug. Turn the drilling spindle until the openings of the sleeve and of the drilling spindle are superimposed. Hold the tool with your hand. Loosen the tool with the help of a drill drift (15).

Interval Where? What? How? Any unusual rattling noises can be eliminated by regreasing. The sleeve (1) moves downwards or upwards with the toothed spindle (2) in the fixed driven sleeve (3) during drill feed. The noises are caused by the necessary clearance between the two toothings of the sleeve and spindle.
If the repairs are carried out by qualified technical personnel, they must follow the indications given in these operating instructions.
