7. Using the cross feed hand wheel, move the cross feed
to its innermost position by turning the hand wheel
clockwise.

8. Using the spindle feed hand wheel, move the spindle to
its innermost (right hand) position by turning the hand
wheel clockwise and then back off by turning dial wheel
five turns counterclockwise. NOTE: If the hand wheel does
not turn freely, check to make sure the spindle lock and
travel control lock knobs are loosened. 

9. Next, position the boring bar by loosening the tool holder
nut and sliding the boring bar towards the innermost side of
the drum, within 1/4” away from the braking surface. 

IMPORTANT NOTE

The boring bar position will have to be changed

whenever a drum of different diameter is machined. The
entire boring bar tool holder may be swiveled to achieve

the best cutting position.

10. Check all clearances closely to make sure that nothing
will “crash” when the power is turned on and the drum
starts rotating. NOTE: It may help to turn the arbor nut
counter-clockwise and manually turn the drum by hand to
pre-check all clearances.

Before turning the power on, make sure the cross feed

speed setting handle and  the spindle feed clutch handle

are in their neutral positions.

11. Turn the power on.

12. Turn the cross feed hand wheel counterclockwise and
bring the boring bar cutting tip into the braking surface
until it just barely contacts the drum surface and makes a
slight scratch cut. 

KEEP HANDS clear of moving parts at all times. Keep

hair, loose clothing, neckties, shop rags, jewelry, fingers,

and all parts of body away from moving parts.

Always wear safety glasses or a face shield. Cutting an

exposed surface such as a brake drum or rotor will

produce flying chips and debris.
