Tensioningthetoothedbelts
Put the basic frame on its feet again.
First release the screw of the left belt tensioner; tension the belt by
pushing the belt tensioner on the inside and tighten the screw again.
The toothed belt must be clamped so that it can still be twisted by
180°easilywith twongersandsothatitcanstillbecompressed
easilywiththengers.
If you cannot tension the toothed belt enough by hand, use a screw-
driver to move the belt tensioners forwards.
Then proceed in the same manner for the right toothed belt.
Important! Both toothed belts must be tensioned to the same
degree!
