ENSURE THAT THE CUTTING TIP IS CLEAR OF THE 

FLYWHEEL PRIOR TO TURNING ON THE SPINDLE 

MOTOR.

MAKE SURE THE DRUM / ROTOR CROSS FEED 

SWITCH IS IN THE NEUTRAL POSITION.  

K

EEP 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, rotor or flywheel will pro-

duce flying chips and debris.

9..  Move the Feed Selector Switch to the Neutral 

position.

10. Set the speed feed dial to 0.

11. Turn on the Main Spindle Power Switch.

12. Rotate the Spindle Feed Hand Wheel clock wise until 

the Cutter begins to cut a shallow scratch cut in the 

flywheel.

13. Back off the Cutter by turning the Spindle Feed Hand 

Wheel Clock wise.

14. Turn off the Main Spindle Power.

15. Examine the scratch cut making sure it is uniform 

around the entire circumference of the flywheel. If the 

scratch cut appears to be deeper on one side of the fly-

wheel and not a  uniform depth, remove the flywheel from 

the arbor, check the mounting adapters and arbor for 

nicks, burrs, or chips, remount the flywheel, and repeat the 

process.

 

Once the flywheel is determined to be mounted properly 

and the scratch cut is good, continue on the machining 

the Flywheel in Step 18.
