Maintenance; Changing The Wheel - Delta 20-140 Instruction Manual

Fig. 22 illustrates the cut-off piece after the cut is com-
pleted. NOTE: The number of cuts per wheel, as well as
the quality of cut, may vary considerably with the cutting
time. Fast cuts cause the wheel to wear more rapidly,
but also help to reduce discoloration and burr.
