3.4.4 Chain transmission with trapezoidal thread adjustment
The chain used to raise and lower the table, must not be slack, but needs to be tensioned enough
that teeth mesh correctly.
The chain tension is adjusted with tensioning pulley. Remove the cover (A), loosen the lock nuts (B)
and move the pulley (C) to tension properly the chain. Do not over-tension the chain.
Do not adjust the chain tension, when table is raising or lowering.
See figure 3-16.
