ALWAYS start spindle rotation before using auto-downfeed to avoid the risk of gear damage.

7.Select one of the three downfeed rates by pulling the knob of the auto-downfeed rate selector out, position the selector over the appropriate detent, then release the knob. Make sure the pin is firmly seated by attempt- ing to move the selector without pulling the knob out.

Note: Refer to the illustration in Figure 38 when selecting the downfeed rate.

Upper = 0.006 in./rev. Middle = 0.0015 in./rev. Lower = 0.003 in./rev.

8.use the coarse downfeed lever to lower the spindle slightly until you can pull the clutch lever out to the left and it locks in place, which will start the auto-downfeed spindle travel.

Spindle Brake

After turning the spindle switch OFF, move the brake lever to bring the spindle to a full stop (see Figures 39–40).

To avoid premature wear of the brake sys- tem, use the spindle brake ONLY after power to the spindle has been turned OFF.
