ADJUSTMENTS
Belt Tension
The drill press drive belt lasts a long time; however, during its life the belt may stretch slightly, which can cause the pulleys to slip under a load. You will then need to adjust the drive belt tension.
NOTICE
The oscillator belt is not adjustable. If the belt shows cracks or is slipping, replace the belt with a new one.
MAKE SURE your machine is unplugged during all assembly, adjustments, or maintenance procedures. Otherwise serious personal injury may occur!
To adjust the drive belt tension, do these steps:
1.UNPLUG THE DRILL PRESS!
2.Open the belt cover. See Figure 15.
3.Loosen the motor lock screw at the side of the headstock. See Figure 16.
4.Gently pivot the motor away from the pushrod rubber until the belt is taut.
5.Hold the motor in position so the rubber pad is held against the motor.
6.Tighten the lock screw, and make sure the belt deflection gap is correct when pinched together between the pulleys. See Figure 17.
•If the gap between both inner sides of the belt is greater or less than 11⁄2" repeat Steps 3 through 6 until the deflection gap is 11⁄2".
•If the deflection gap is 11⁄2," close the belt cover until it snaps shut. The motor will not start until the cover is closed.
