The drill press main drive belts last a long
time; however, during machine life, a belt may
stretch slightly which can cause the pulleys to
slip under a load. You will then need to adjust
the motor-to-idler pulley belt tension to com-
pensate for this normal stretching.
NOTE: The spindle-to-idler pulley belt automati-
cally adjusts to the correct tension when the
motor-to-idler pulley belt tension is adjusted.
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!

ADJUSTMENTS
To adjust the drive belt tension, do these
steps:
1. UNPLUG THE DRILL PRESS!
2. Open the belt cover.
3. Loosen the motor lock screw at the side of
the headstock, as shown in Figure 22.
4. Gently pivot the motor away from the push
rod rubber until the belt is tight.
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
23).
• If the gap between both inner sides of the
belt is greater or less than 1 1 ⁄
2
", repeat
Steps 3 through 6 until the deflection gap
is 1 1 ⁄
2
".
