Checking Saw-Blade Parallelism
To check the parallelism of saw blades that cut
parallel to the carriage travel, the setup procedure for
“straightness” above is followed.
Place the A-1519-2.4ZB target on the blade at the
closest point to the laser (3:00) and zero. Rotate the
blade 180 degrees so the target is at farthest point on
the blade from the laser (9:00). Any deviation from
zero is a measure of the parallelism errors of the blade
to the carriage travel.
Checking Plumbness of Blades
With the laser leveled, both vertical laser planes are plumb to earth and the plumbness of the blade can
easily be checked.
1. Place a target on the blade at the 12:00 position and zero it.
2. Rotate the blade so the target is at 6:00 (or 3:00 or 9:00). Any deviation in the target reading is a
measure of how far out of plumb the blade is.
