The direction ofmovement must allow chips to clear freely.Move workpiece so that chisel slot is releasingchips into the already-cut part of the workpiece(Figure 11-1).Do not have chisel slotagainst the blind end of the mortise, as thechips will not be able to clear the chisel.This can cause overheating and possiblebreakage of chisel or bit.7. When cutting deep mortises, make the cut inseveral stages of approximately 1" each, toallow chips to clear. To prevent breakout at theback of the workpiece when cutting throughmortises, use a piece of scrap material underthe workpiece as support.Figure 11-112.0 StorageIf the mortiser will be stored for an extendedperiod, use the depth stop to help secure head inposition; this will relieve stress upon the hydrauliccylinder.13.0 Optional accessoriesPremium Mortise Bit and Chisel Sets:Stock no.
