ASSEMBLY
ADJUSTING UPPER BLADE GUIDES AND
THRUST BEARING
See Figures 24 - 25, page 27.
WARNING:
Saw table in drawing has been removed for clarity
purposes. Never operate saw without all compo-
nents in place and in working order. Failure to do
so could result in possible serious personal injury.
NOTE: Blade must already be tensioned and tracking prop-
erly. Notice the bearing holder on the shaft is eccentric.
Adjusting Blade Guides:
 Loosen bearing adjustment screws and rotate the blade
guides as close to the blade as possible without pinching
the blade. The thickness of a dollar bill on each side of
blade is a good rule of thumb.
 Tighten thumb screws (plastic).
 Loosen thumb screw (metal) and turn knurled knob to
move the blade guide bracket in or out until the front
edge of the blade guides are just behind the "gullets" of
the saw teeth.
 Tighten thumb screw (metal).
Adjusting Thrust Bearing:
 Loosen thumb screw (metal) and turn knurled knob to
move the thrust bearing in or out until the bearing is 1/64
in. behind the blade.
 Tighten thumb screw (metal).
 Blade thrust bearing should be adjusted so that the
back edge of the blade overlaps the front face of the
ball bearing approximately 1/8 in. To change position of
the bearing, remove screw bearing, and back off knurled
knob completely to remove the bearing shaft. Notice the
bearing holder on the shaft is eccentric. Reinstall the
bearing shaft, the bearing, and the screw. Examine the
overlap between the bearing face and the blade. Change
the position of the bearing shaft until the overlap is
approximately 1/8 in.
