8.3.3 Replacing the chain and sprockets
The chain comes correctly pre-tensioned from the factory.
It is not necessary to re-tension the chain because of the very slight wear.
As a rule the chain will not have to be changed for several years.
● Undo the four screws holding the
sampling equipment in the lid.
● Turn the sampling equipment out of the
lid so that the chain is on top.
● Loosen the threaded pin on the
sprocket (drive) with a spanner.
● Place a spanner on the square of the
chain tensioner and loosen the chain.
