All toothed belts in linear units need tension, which is required to guar-
antee safe engaging of the teeth.
The required pretensioning of the toothed belt must be checked with a
pretensioning measurement appliance.
The specific pre-tensioning values for the different types of linear unit are
dependent on environmental parameters, such as the length of the unit,
acceleration and loads to be moved and can be queried with RK
Rose+Krieger GmbH for special cases.
Tension the toothed belt with the belt tensioning kit.
Tension the toothed belt (1) by steadily tightening the tensioning screw
(2) on the front of the slide (3) clockwise.

The toothed belt of the linear unit must be replaced every 8 years irre-
spective of the amount of use and the environmental influences.
