Adjusting stationary jaw for
high accuracy angle cutting:
1. Raise the saw arm to full height and lock it in position
with the shut-off valve.
2. Open the vise to full width.
3. Loosen the pivot and lock bolts shown in
Figure 1
.
4. Open the shut-off valve and lower the saw arm until it
is at full horizontal position.
5. Take a machinist's protractor and set it to the angle you
need to cut.
6. Lay the protractor on the saw table and place one
edge of the protractor against the saw blade and the other
edge against the stationary vise jaw. (
Figure 4
.)
7. Adjust the stationary vise jaw until its angle is correct
with respect to the blade, then lock the stationary jaw
firmly using the pivot and lock bolts.
The saw is now accurately set to the exact angle
you have set on the machinist's protractor. You can now
saw the workpieces according to instructions on
Angle
sawing
.
Adjusting angles with the
scale on the saw table
There is a scale on the rear of the saw base which
can be used to establish the angle of cut.
1. Raise the saw arm to full height and lock it in position
with the quick shut-off valve.
2. Slide the locking jaw to full open position.
3. Loosen the pivot and lock bolts shown in
Figure 1
.
4. Lay a straight edge on the saw frame so it contacts the
stationary vise jaw. (See
Figure 3
.)
5. Turn the vise jaw until the straight edge is above the
angle of cut you require as shown on the angle gauge.
6. Tighten both the pivot and lock bolts.
7. Remove the straight edge and proceed to cut as
described in
Angle sawing
.

Setting the blade guides
To produce accurate cuts the distance between the
blade guide/supports must be set correctly. Whenever
possible, set the blade guide assembly so it clears the
workpiece by approximately 1/8 inch on either side of the
workpiece.
The guides may be moved by loosening the lock
handles which secure the bracket bars to the saw arm.
There is, however, a limit to how close the guide can
be set with respect to the table. When set too close to the
blade clearance slot, the guide bearings can hit the table
casting and prevent the arm from moving to full horizontal.
When this happens, the saw cannot complete its cut.
This won't be a problem with the right-hand guide.
On the other hand, the left-hand guide typically cannot be
much closer to the right-hand guide than 6 inches or so.
Therefore, when cutting smaller section material, be sure
the blade is correctly adjusted, tensioned properly, sharp,
and appropriate to the type of material being cut.
