4.6.1 Tightening the chain
(see Fig. 21: Chain drive /spray nozzles)
The chains must be tightened so that the centre of each chain can be raised by hand be-
tween the chain wheels by approx. 3 mm ("A") or pressed together by 4 - 5 mm ("B").
The chain can be tensioned by adjusting the pressure spindle (26) in the direction of the ar-
row.
The suspension chains on the left and right ("A") must always have the same
tension!

The wearing limit of a chain has been reached when the distance "s" between the 1
st
and 12
th
roller exceeds 135.0 mm; see Fig. 22: Wear measurement chain drive.
With a brand new chain this dimension "s" should measure 131.4 mm.
These values are valid for all 3 chains.
