G0641 Double Miter Saw
Lowering Speeds
The lowering speeds of the hold-downs and
blades are independently adjustable. The goal is
to synchronize these rates so that the hold-downs
grip the workpiece before the blades begin the
cut. After the cut is complete and the blades are
fully raised, the hold-downs will raise and release
the workpiece.
When making adjustments, first adjust the lower
-
ing speed of the blades, then adjust the lowering
speed of the hold-downs.
To adjust the lowering and raising rate of the
saw blades:
1. DISCONNECT SAW FROM POWER!
adjusting lowering speeds
3. Secure a scrap piece of the same material
you will use for the production run under the
hold-downs, then lower and secure the front
guard.
4. Connect the saw to power, turn the motor on,
and use the foot pedal actuator to make test
cuts.
5. Adjust the lowering and raising speeds of the
blades to produce cuts that are without tear
out (too fast) and without burning (too slow).
Note:
Turning the speed knob in (clockwise)
decreases the speed, and turning out (coun
-
terclockwise) increases it.
6. Continue to make adjustments and test cuts
until you are satisfied with the lowering and
raising speeds of the blade, then re-tighten
the jam nut to secure the setting.
To adjust the lowering rate of the hold-
downs:
1. DISCONNECT SAW FROM POWER!
2. Remove the two thumb screws from the front
guard and raise it to the upper position.
When properly adjusted, the hold-downs
prevent the workpiece from being drawn into
the blades or thrown from the saw when cut
-
ting. Always make sure the hold-downs are
properly adjusted for the workpiece and that
they securely clamp the workpiece before
the blades begin the cut.
