11. IMPORTANT: Make certain the spindle taper (Q) Fig.
15, and tapered hole in chuck (R) are clean and free of
any grease, lacquer or rust preventive coatings. NOTE:
Household oven cleaner can effectively remove any
substance from the spindle and chuck; however,
carefully follow the manufacturer's safety rules
concerning its use.

AS POSSIBLE MAKING SURE THE CHUCK JAWS
ARE UP INSIDE CHUCK.

spindle. IMPORTANT: To avoid damage to the chuck,
NEVER drive the chuck onto the spindle with a metal
hammer.
