9.3.3 Toothed transport belt
The transport side of the toothed belt is lightly lubricated on delivery to
increase the service life of the toothed belt. Apply subsequent lubrication
to the toothed belt if necessary by wiping a lightly oiled rag (mineral oil
viscosity 68 according to DIN, Aral/Shell) along the transport side of the
toothed belt.
9.3.4 Toothed drive belts on the curve
The toothed belt is wear-free. If the pre-tensioning is less than 22 ± 2 Nm,
