Adjusting Blade Guide And Blade Support Bearing - Jet JWBS-14CS Operating Instructions And Parts Manual

3. Tighten lock knob. Make sure blade guide
blocks (C, Figure 30) are still flat to the
blade. If adjustment is necessary, loosen
lock knob (A, Figure 30) and rotate
assembly until guide blocks are flat to blade.
4. If movement of the blade guide assembly
seems "stiff" when being raised or lowered,
it can be adjusted to slide more easily. This
is controlled by an internal spring and ball
which provide varying degrees of resistance
against the guide post. Use the set screw
(D, Figure 30) to adjust the tension of this
spring. To adjust tension on the spring,
loosen knob (A, Figure 30), use a hex
wrench to tighten or loosen set screw (D,
Figure 30) until desired tension is reached,
then re-tighten knob (A, Figure 30).
