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.
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 1 1 ⁄

Steps 3 through 6 until the deflection gap

• If the deflection gap is 1 1 ⁄

belt cover until it snaps shut. The motor
will not start until the cover is closed.
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!
