122. Rotate spring cap clockwise to decreasespring tension; counterclockwise to increase.3. Tighten knob (A).Figure 7-4: spindle return spring adjustment8.0 Operation8.1 Operating controlsRefer to Figures 8-1 and 8-2.Depth stop and scale.All models: Turn scale ring (A 1 ) until desireddepth on scale aligns with indicator. Tighten lockhandle (A 2 ).JMD-45VSPFT only: Use above procedure forgeneral drilling and powerfeed operation. Fortapping procedures use front depth stop system– turn knurled knob (A 3 ) until pointer (A 4 ) reachesdesired mark on scale.Downfeed handle (B).
