Installing the Mortising Chisel and Drill Bit
The 34-250 Mortising Machine uses 5/8” diameter shank chisels with a 3” cutting depth.
Please contact RIKON Technical Support at 877-884-5167 before using chisel sizes other
than provided.
• UNPLUG MACHINE BEFORE INSTALLING CHISEL AND BIT SET.
• WEAR PROTECTIVE GLOVES WHILE HANDELING THE CHISEL.
• MAKE SURE DRILL BIT PROTRUDES 1/16” TO 3/16” PAST CHISEL POINT.
WARNING ! !
1. Open the chuck access cover (A-Fig.09).
