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.
Warning!
Danger from automatic start
The conveyor chain can start to move when work is being carried out.
There is a risk of crushing and electric shock.
► Disconnect the cable from the power supply before starting the work.
● 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.
