Add or remove links
Whenever it is necessary to increase or
decrease the length of the chain, check that the
link clip (A) must always have its opening turned
to the opposite side (opposite turning direction
of the chain).
Chains maintenance
ATTENTION
- Every maintenance must be done when the equipment is turned off.
- The clearance between the activation chains of the equipment must be checked every
50 service hours or at least once a week.
- When wear occurence in the chains is perceived, replace them. To remove them,
release the tightener that stretches the chains.
- After assembling a new chain, adjust the clearance and press it using your thumb on
the central point of the distance between the sprockets to check if the clearance is
excessive.
- During offseason, remove all the activation chains of the equipment, wash them with
kerosene or diesel oil and store them deeped on oil inside a container until the next
crop.

Chain tightener
The chain clearance adjustment is very important for the functioning of the transmission
chain, while extend the lifetime of the other components on the system such as axles and
bearings.
An excessive tension disfavors the formation of an oil layer between the chain
components, leading to a premature wear and
heating, while causing a tension on the whole
transmission system. On the other hand, an
excessive clearance is also harmful as it
causes vibrations and chain bending what
may cause wear on this part.
