1) Depending on the specific product, reduced values may be possible, e.g.with an aluminum housing.
2) The tightening torques for the threaded plugs are valid for the condition "dry" and "lightly oiled".
3) The tightening torques for the threaded plugs are valid for the condition "dry" – in the condition "lightly oiled", the tightening torques
for M10×1 are reduced to 10Nm and for M12×1.5 to 17Nm.
