Operating Controls And Adjustments; Raising And Lowering Spindle - Delta 43-431 Instruction Manual

A 4-1/2" spindle guard is supplied with these machines.
The diameter of the spindle guard should be at least 1" more than the maximum cutting circle of
the shaper cutter and the height of the guard should not exceed 1/4" above the material.
To attach spindle guard:
DISCONNECT TOOL FROM POWER SOURCE.
1. Place one of the 3/4" I.D. washers (A) on the spindle (Fig.20).
2. Place the spindle guard (B) Fig. 21 on the spindle. Install the other washer (C) and the "keyed" washer (D) on the
spindle.
3. Thread the spindle nut (E) Fig. 22 on the spindle. Place one wrench on the flats at the top of the spindle and one
wrench on spindle nut (E) and tighten.
4. IMPORTANT: Always place the "keyed" washer (D) Fig. 21, on the spindle before screwing on the spindle
nut (E) Fig. 22. The "keyed" washer (D) Fig.21 prevents the spindle nut (E) Fig. 22 from loosening when the
spindle turns counterclockwise.
