Avoid damage due to stresses
Use suitable tools for the assembly. Mount gear wheels and
toothed belt pulleys without force on the output shaft and avoid
mounting by driving or hammering on.
The gear unit can be damaged if stress occurs during mounting.
► Seal any gap over a wide area when attaching to the output side
► Make sure that the surfaces of the attached parts have a low
roughness
► Use only screw head seals and o-rings for sealing
