13.IMPORTANT: Make certain the spindle taper (Q) Fig. 17, 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 sub- stance from the spindle and chuck; however, carefully follow the manufacturer's safety rules concerning its use.

14.IMPORTANT: OPEN THE CHUCK JAWS AS WIDE AS POSSIBLE MAKING SURE THE CHUCK JAWS ARE UP INSIDE CHUCK.

15.Carefully drive chuck (S) Fig. 18, onto the spindle with a block of wood and hammer, or a rubber mallet (T) as shown. This will seat the chuck properly on the spindle. IMPORTANT: To avoid damage to the chuck, NEVER drive the chuck onto the spindle with a metal hammer.

16.Lift up the motor pulley cover (A) Fig. 19.

17.Loosen the tension lock knob (B) Fig. 19, and pivot the motor toward the front of the drill press as shown.

18.While holding the motor toward the front of the drill press head, position the belt (C) on the desired steps of the motor and spindle pulleys, as shown in Fig. 19. A belt positioning chart (D) is provided on the inside top cover of the drill press for your convenience.

19.After the belt is positioned on the desired steps of the motor and spindle pulleys, pivot motor away from the drill press head until the belt is properly tensioned and tighten tension lock knob (B) Fig. 19. The belt should be just tight enough to prevent slipping. Excessive tension will reduce the life of the belt, pulleys and bearings. Correct tension is obtained when the belt (C) can be flexed about one inch out of the line midway between the pulleys using light finger pressure.

20.Place the magnetic base lamp (A) Fig. 20, on the left side of the drill press head.

21.Install a 40 watt or less, 120 volt, reflector track type light bulb (not supplied), into the magnetic base lamp.

WARNING: To reduce the risk of fire, use 40 watt or less, 120 volt, reflector track type light bulb (not supplied). A standard household light bulb should not be used. The reflector track type light bulb should not extend below the lamp shade.

22.Plug the magnetic base lamp into a 110-120 Volt, 60 HZ receptacle.

CAUTION: Make sure that the power cord for the magnetic base lamp is clear of all moving parts on the drill press.
