need for adjustment should rarely occur when the saw is
used properly. If the guides do get out of adjustment
though, it is extremely important to readjust immediately.
If improper adjustment in maintained, the blade will not
cut straight, and if the situation is not corrected it will
cause serious blade damage. 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
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
bushing and can be adjusted.
3. Loosen the nut while holding the bolt with an Alien
wrench.
4. Position the eccentric by turning the bolt to the desired
the second blade guide bearing in the same

position of clearance.
