Alignments and Adjustments (continued)
Adjusting Lower Blade Guides and
Blade Support Bearing
1. Disconnect machine from the power
source.
2. Blade must already be tensioned and
tracking properly.
3. Loosen thumb screws and move guide
blocks as close to blade as possible
without pinching it. The thickness of a
dollar bill on one side of blade is a good
rule of thumb.
4. Tighten thumb screw.
5. Loosen thumb screw and move the
guide block support in or out until the
front edge of the guide blocks are just
behind the "gullets" of the saw teeth.
6. Tighten thumb screw.
7. Loosen thumb screw and move the sup-
port bearing in or out until it is 1/64"
behind the sawblade
8. Tighten thumb screw.
9. The blade support bearing should be
adjusted so that the back edge of the
blade overlaps the front face of the ball
bearing approximately 1/8". To change
position of the bearing, remove screw
and bearing. Loosen thumb screw and
remove the bearing shaft. Notice the
bearing holder on the shaft is eccentric.
Re-install 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".
