After cutting clean the masonry bench saw and check for damages.
Necessary repairs must be carried out immediately (see spare parts list).
Take off the water pump and put it in a bucket. Plug in the mains plug an let the masonry bench saw run for 1
or 2 minutes. Unplug the mains plug and insert the water pump back in the masonry bench saw.
