4. Loosen the belt tension locking knob and use the belt ten- sion lever to push the motor towards the
rear of the drill press, ensuring that the belt is under tension. Tighten the belt tension locking knob.
Close the belt housing cover. If desired, tighten the cover knob to prevent it from rattling during opera-
tion.
NOTE: Ensure that the belt runs on the same setting of each pul- ley (e.g. if the belt is on the third
setting of the motor pulley, it should be on the third setting of the spindle pulley as well).
SPINDLE RETURN SPRING
The spindle is equipped with an auto-return mechanism. The main components are a spring and a
notched housing. The spring was properly adjusted at the factory and should not be readjusted unless
absolutely necessary.
1. Unplug the drill press.
2.Using an adjustable wrench (not included), loosen the two
nuts (Fig. 16 - 1) approximately 1/4” (6 mm). Do not remove
the nuts from the threaded shaft. Do not allow the spring or
spring housing to slip out of control.
3.While firmly holding the spring housing (Fig. 16 - 3),
carefully pull the spring housing out until it clears the raised
notch (Fig. 16 - 2).
4.Turn the housing so that the next notch is engaged with the
raised notch (Fig. 16 - 2).
●To increase the spindle return tension, turn the spring
housing counter-clockwise.
●To decrease the tension, turn the spring housing clockwise.
5.Tighten the two housing nuts. Do not overtighten the two
nuts. If the nuts are tightened too much, the movement of the
spindle and feed handles will become sluggish.
WARNING:
To avoid injury, make sure the chuck key is
removed from the chuck before starting any drilling opera-
tion.
REPLACING THE BELT
1.
To replace the belt, open the belt housing cover (Fig. 17 -
1) by turning the belt cover knob (Fig 17 - 2) two rotations
counter- clockwise and flipping the belt housing cover up.
2.
Loosen the belt tension knob (Fig. 17 - 3) and use the belt
tension lever (Fig. 18 - 1) to pull the motor forward and
relieve belt tension. Tighten the belt tension knob.
