Fig. 6-2: General Data
Note: The GTM planetary gearboxes are designed for the indicated
specified permittable technical data. With regard to the
operating safety it is only allowed to use the gearboxes in this
case under view of all operating factors. Any sort of overload
of the gearbox is classified as non-intended use. Any changes
made to the gearbox voids all liability on the part of Bosch-
