Tensionning the drive chain (Fig.11)
The drive chains need no tensionning since the tension is always assured by an automatic chain span-
ner.
To change the drive chain, pull the chain spanner backwards and remove the chain from the sprockets
and remove the chains.
After the chain is replaced always assure the chain spanner is well placed onto the chain.
To change the drive chain for the rise and fall of the table, pull the chain spanner lever to the back and
remove the chain.
Attention: do not turn the sprockets on one of the 4 posts of the table whilest changing the chain; this
will lead into a disorder of the parallelism of the table!

- belt tension not correct: tension the belt
- motor overload due to incorrect feed rate: reduce the feed rate
- blunt tools: sharpen tools
3. Vibration of the machine :
- worn or damaged belt: replace the belt
