1.
Turn off saw, unplug from power source.
2.
Make sure blade is fully tensioned.
3.
Set blade tilt to "0" (90 degrees).
4.
Place a machinists square or other 90-degree
measuring device on table and against blade
(Figure 9-2). Do not deflect blade by pushing
into it.
Figure 9-8: inspecting blade squareness
5.
If side of blade does not lie flush against square,
first check that the set screws (see G, Figure 9-
5) protrude evenly into the clamping area.
Adjust if needed.
6.
If blade is still not perpendicular, loosen eight
screws on trunnion plates, at front and back of
saw (Figure 9-9).
7.
Nudge trunnion/arm assembly until side of
blade is flush to square.
8.
Tighten all screws at front and back.
9.
If needed, loosen screw on pointer (K) and
adjust it to zero. Tighten screw.

9.7 Adjusting blade oscillation
Blade movement can be adjusted to accommodate
different wood stock and types of operations. For
example, for faster, more aggressive cutting the
blade can be adjusted for slight backward
movement on the upstroke, and slight forward
movement into the wood on the downstroke. For
slower, fine detail work and more control,
completely vertical blade movement is often
preferred.
This adjustment is based upon user's preference; as
the scroller gains experience, he/she will get a feel
for the oscillation that is most efficient for the work
at hand.
1.
Turn off saw and remove blade.
2.
First verify that upper arm is parallel to table
surface (Figure 9-10). Push arm down, and
measure at front and back of arm; if
measurements
adjustment knob (L) until upper arm is parallel.

3.
Install blade. Adjustments to blade oscillation
can be subtle; place a square or block of wood
on table and alongside blade as reference.
4.
Loosen screws on motor flange (M, Figure 9-
11) with 4mm hex wrench. Only loosen screws
enough to allow motor rotation.
