3. Tighten lock knob. Make sure blade guide
blocks (C, Figure 30) are still flat to th e
blade. If adjustment is necessary, loose n
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 a nd 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 ad just tens ion on t he sp ring,
loosen knob (A, Figure 30), use a hex
wrench to tighten or loosen set screw (D,
Figure 30) until desired tensio n is reached,
then re-tighten knob (A, Figure 30).
Blade guard has been
removed for picture clarity. Never operate
the band saw without all guards in place and
in working order.
1. Disconnect machine from power source.
2. Blade must already be tensioned and
tracking properly.
3. Loosen thumb screws (E, Figure 31) and
move guide blocks (C, Figure 31) as close
to the blade as possible without pinching it.
4. Tighten thumb screws (E, Figure 31).
5. Loosen thumb screw (F, Figure 31) a nd turn
knurled knob (G, Figure 31) to mov e the
guide block bracket in or out until the front
edge of the guide blocks are just behind the
"gullets" of the saw teeth.
6. Tighten thumb screw (F, Figure 31).
7. The blade support bearing (K, Figure 31)
should be adjusted so that the back edge of
the blade overlaps the front face of the ball
bearing approximately 1/8". To c hange
position of the bearing, remove screw (L,
Figure 31), and bearing (K, F igure 31).
Loosen thumb screw (H, Figure 31) and
back off knurled knob (J, Figure 31)
completely to remove the bearing shaft.
