Protective hood CanopyE Tightening with pulse screwdriver or impact wrench without adjustment checking device Tightening by hand, using spanner without torque measurement NOTICE Property damage Damage to screws and/or counter threads from wrong tensioning is possible. Foundation bolts, hub bolts and bearing cover bolts must always be tightened generally according to screw connection class "". *)The tightening torques applying to these add-on parts can be found in the instructions supplied by the manufacturers of the parts. 4 / 7BA 5 en 0/2.7.2 Tightening torques and initial initial stressing forces The tightening torques apply to friction coefficients of total = 0.1. The friction coefficient total = 0.1 applies here to lightly oiled steel bolts, black-annealed or phosphatised and dry, cut counter threads in steel or cast iron. Lubricants which alter the friction coefficient are not permitted and might overload the screw connection.
