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.

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.

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.
