A small piese of MDF from cutting at 45 degrees angle was stuck under the Outfeed Table.
When the angle of the blade was returned to 0 degrees, the motor mounting frame pushed the Outfeed table centre up more then 2mm.
After removing the MDF debris the Table is back to the normal position.
But plese watch the saw carefulle in near future – to check for any follow up errors.
And be carelull in the future – when returning the blade from angled cutting.
Thaanks to Simon for noticing and reporting. And for calibrading the angle of the Sliding Table.
