BA 2012
Operating Instructions, 03/2013, 70000004024300

Observe the type of construction specified on the rating plate. This ensures that the correct

quantity of lubricant is provided.
Use all the fastening means which have been assigned to the relevant type of construction.
Cap screws cannot be used in some cases due to a lack of space. In such cases, please

contact Technical Support quoting the type of gearbox.

4.3

Tightening torque for fastening bolts on the gearbox

The general tolerance for the tightening torque in Nm is 10 %. The friction coefficient is

0.14 μ.
