Headstock Faceplate
Installing Faceplate
To prevent faceplate and workpiece sepa-
rating from spindle during operation, head-
stock faceplate MUST be firmly threaded
onto spindle and secured in place by fully
tightening the two faceplate set screws.
If these instructions are not properly per-
formed, serious personal injury could occur.
Note: To remove faceplate, disconnect lathe from
power source and perform steps above in reverse.
To install faceplate:
1. DISCONNECT MACHINE FROM POWER!
2. Insert indexing pin into an indexing hole and
rotate spindle until pin engages to prevent
spindle from turning while you tighten face-
plate, as shown in
Figure 23.
3. Thread faceplate onto spindle until it is snug.
4. Using included 4mm hex wrench, tighten two
set screws along inside diameter of faceplate
to secure it to spindle (see
Figure 23).
