G0641 Double Miter Saw
Aligning Pivot Arm
Assembly
aligning blade pivot arm
The pivot arm assembly is aligned at the factory
to be precisely 45° from the fence. This setting
should never need to be changed or adjusted.
If your cuts are not precisely 45°, do the following
before performing this procedure:
• Check the saw blades for warping or bent
teeth—replace if necessary (
Page 22).
• Make sure the hold-downs firmly clamp the
workpiece to the fence before the blades
begin the cut (
Pages 19 & 20).
• Remove any resin build-up or debris from the
table, fence, and fence stop.
To realign the pivot arm assemblies:
1. DISCONNECT SAW FROM POWER!
2. Raise the front guard up, and remove the
inner blade guard to access the pivot arm
assemblies and motors (see
Figure 45).
Figure 45. Guards removed to access pivot arm
assemblies.
3. Use a 19mm wrench to loosen, but not
remove, the front and rear motor base mount-
ing bolts.
4. Use a 13mm wrench to loosen the alignment
jam nuts on either side of the motor base
(see
Figure 46).
5. With the machine still disconnected from
power and your hands away from the blades,
press the foot pedal actuator to bring the
blades down and into the miter slots.

Note: It is safer and more convenient to
remove the saw blade opposite from the pivot
arm assembly that you are working on.
