rawing prepared in accordance with the order. NOTICE Property damage Damage in the gear unit from blows or impact is possible. Fit the coupling with the aid of suitable fitting equipment.The shaft sealing rings and running surfaces of the shaft must not be damaged when pulling in the coupling parts. NOTICE Property damage Damage to the gear unit or individual components is possible from inadequate alignment. When setting up the drives for the alignment of the individual components, observe the specificationsin the related instructions for the components. Unacceptable large errors in the alignment of the shaft ends to be connected due to angular and/or axial misalignments result in premature wear and material damage.When using gear couplings, defined alignment deviation might be necessary, please observe theinstructions for the gear couplings.Insufficiently rigid base frames or sub-structures can also cause radial and/or axial misalignmentduring operation, which cannot be measured when the unit is at standstill. Note Gear units with weight that requires the use of lifting gear must be attached at the points shown insection 4. "Transport and storage". If the gear unit is to be transported with add-on parts, additionalattachment points may be required. The position of these attachment points is shown on the order-related dimensioned drawing. 3 / 9BA 5 en 0/2.3.2.1 Alignment Order-specific machined surfaces (alignment surfaces) are provided on the gear unit top side for preliminary alignment in horizontal direction. Alignment surface: To further facilitate alignment, the gear units are provided with alignment threads in the housing base. For the exact position of the alignment surfaces, refer to the drawings in the gear unit documentation. The alignment surfaces are for aligning the gear unit horizontally, in order to ensure correct running of the gear unit. Note The values punched into the alignment surfaces must always be observed.
