CHANGING SPEEDS AND ADJUSTING BELT TENSION

To reduce the risk of injury, turn unit off and disconnect it from power source before installing and removing accessories, before adjusting or when making repairs. An accidental start-up can cause injury.

NOTE: Sixteen spindle speeds are available on the drill press. A belt-positioning speed chart is located on the inside top cover of the drill press.

1.Lift cover (H1) Fig. 39.

2.Move belt tension lever handle (I1) Fig. 39 up and to the right and engage the hook (J1) Fig. 39 (inset) to hold the tensioner arm in place.

3.Choose the appropriate speed for the tool you are using and position the belts on the pulleys accordingly. See chart (Fig. 38) on the inside cover of the drill press head.

4.NOTE: The belts are ribbed with grooves, so make sure the belt grooves match up with the pulley grooves.

5.Lift handle and move to left (as shown in Fig. 40) until the belt tensioner arm (K1) rests against the belts.

NOTE: Don't force the handle any further to the left. It is set with the proper tension for the belts.
