Lower Bearing Guide Adjustment
Disconnect machine from the
power source, unplug before making any
adjustments. Blade teeth are sharp; use care
when working near the saw blade. Failure to
comply may cause serious injury.
1. Disconnect the machine from the power
source, unplug.
2. Blade tension must be properly adjusted
prior to bearing guide setup; see “Adjusting
Blade Tension” page 15.
3. Loosen the thumb screw (B, Fig. 4) and
slide the bearing and bearing post until the
space between the back-up bearing (A, Fig.
4) and the back edge of the blade is
approximately 1/64”. A convenient way to
achieve this spacing is by placing a dollar
bill folded twice (four thicknesses) between
blade and bearing. Tighten thumbscrew.
4. Loosen the socket head cap screw (C, Fig.
4) and slide the bearing assembly until the
bearing guides rest just behind the gullet of
the blade teeth. You may need to readjust
the back-up bearing. Tighten socket head
cap screw.
5. Loosen the thumb screw (D, Fig. 4) and turn
adjusting screw (E, Fig. 4) clockwise or
counter-clockwise until the bearing is
approximately 1/64” away from the side of
the blade.
6. Adjust the opposite side bearing.
7. Tighten thumbscrew (D, Fig. 4). Check to
make sure the adjustments have not
changed during the tightening process, and
that the bearing guides do not pinch the
blade.
Mounting the Table
1. With help from another person, mount the
table. Remove the table insert (F, Fig. 5)
and table pin (G, Fig. 5).
2. Slide the saw blade through the slot in table
where the table pin was located. Rotate the
table 90 degrees so that the miter slot is
parallel to the blade, and to the right of the
blade when facing the bandsaw.
3. Line up the trunnions so that the bolts feed
through the trunnion support bracket.
Secure the table with two lock knobs (H, Fig.
6). Re-install the table insert and table pin.
