requirements. Loosening knurled screw ( 21 ) by turning knob ( 4 ), moving the scale to the required depth,
then fastening the knurled screw( 21). Now the machining depth could be controlled.
7.6 Tapping
Put the “Selection Switch” ( 17 )on the tapping position first, turn the feed lever( 5) and let the tap
approaches the work piece, a proper manpower force (based on the size of grescrew) shall be exerted in
order to let the tap comes into the hole. The spindle will be rotated in reverse when the screw depth is
reached, promptly turn the feed lever( 5) in counter clockwise direction, in order to let the tap comes out.
