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.

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.

bearing guides rest just behind the gullet of
the blade teeth. You may need to readjust
the back-up bearing. Tighten socket head

make sure the adjustments have not
changed during the tightening process, and
that the bearing guides do not pinch the
blade.
