29.  Rotate, push in, or pull out the adjustment 

cam to adjust the deadman arm so it is as 

parallel as possible with the lathe bed in 

both the vertical and horizontal plane. 

Note

: You may have to rotate the deadman arm 

so the arm clevis allows the arm to be tilted 

in a particular direction.

—  To tilt the arm in the vertical plane, rotate

 

the knurled adjustment cam. 

—  To tilt the arm in the horizontal plane, slide 

the adjustment cam in or out of the deadman 

housings.

28.  Using a 3mm hex wrench, loosen the four 

locking set screws (Figure 19) that lock the 

adjustment cam in position.

24.  Using a 6mm hex wrench, loosen the 

dovetail lock cap screw at each end of the 

taper attachment, as shown in Figure 17.

25.  Turn the taper angle control knob (Figure 

17), so the taper attachment points to zero 

degrees as shown on the scale.

26.  Re-tighten both dovetail lock cap screws.

27.  Slide the deadman clamp along the lathe 

way to a position where the saddle will not 

contact the clamp when cutting tapers. 

There should be approximately 1" of safety 

clearance or "saddle safety gap," as shown 

in Figure 18. You must double check this 

clearance to prevent a deadman clamp 

carriage crash.
