Because guide adjustment is a critical factor in the performance of your
saw, it is always best to try a new blade to see if this will correct poor
cutting before beginning to adjust. If a blade becomes dull on one side
sooner than the other, for example, it will begin cutting crooked. A blade
change will correct this problem, the guide adjustment will not. If a new
blade does not correct the problem, check the blade and guides for proper
spacing.
NOTE: There should be from 000 (just touching) 001 clearance between
the blade and guide bearings, to obtain this clearance adjust as follows.
1. The inner guide bearing is fixed and cannot be adjusted.
2. The outer guide bearing is mounted to an eccentric bushing and can
be adjusted.
3. Loose the nut while holding the bolt with an Allen wrench.
4. Position the eccentric by turning the bolt to the desired position of
clearance.
5. Tighten the nut.
6. Adjust the second blade guide bearing in the same manner.
BLADE TRACK ADJUSTMENT
1. Open the blade guard.
2. Remove the blade guide assemblies (top and bottom)
3. Loosen the hex head screw in the tilting mechanism to a point where it
is loose but snug.
4. With the machine running, adjust both the set screw and blade tension
knob simultaneously to keep constant tension on the blade. The set
screw and blade tension knob are always tuned in opposite directions,
when one is turned clockwise the other is turned counterclockwise.
The blade is tracking properly when the back side just touches the
shoulder of pulley or a slight gap appears near the center line of the
pulley. Care should be taken not to over tighten the saw blade since
this will give a false adjustment and limit life of the blade.
5. Tighten the hex head screw in tilting mechanism IMPORTANT:
Sometimes for trying to make this critical adjustment it is possible to
cause the basic setting to be misaligned. Should this occur, proceeds
as follows:
a. Loosen the set screw and back it out as far as it can go and still
remain in the threaded hold.
b. Turn the hex head screw clockwise until it stops (do not
tighten).
c. Turn the set screw clockwise until its bottoms, then continue for
half a turn and check the tracking by turning on the machine.
d. If further adjustment is required, go back to step 4.
6. Turn off power to the machine.
7. Replace the blade guide assemblies – it may be necessary to loosen
the blade tension lightly.
8. Adjust the vertical position of blade guide bearing assemblies so that
the back side of the blade just touches the ball bearings.
