realignment Method 1
This procedure deals with the most common source of misalignment that occurs when the guide rails are not parallel with the blade.
1.Set the cutting depth such that the blade passes through the table, not over.
2.Place a straight edge (i.e. carpenter’s square) on the cutting table as shown in Figure 20.
3.Loosen the left and right guide rails by loosening the fasteners found at the ends of the rail. The left rail should be slightly loose, so there is not too much play during adjustments, but the right rail should move freely.
required. However, if scenario A or B (described below) occurs, other adjustments may be required instead.
a.If the straight edge only touches the blade when the table is positioned midway along the rail or at the ends of the rail, then the rail may be deformed (i.e. bowed). See Figure 21. Perform test cuts to determine if the rail should be replaced. Typically, a bowing displacement of up to 0.2mm (.008 in.) will not affect cutting accuracy.

b. If the straight edge touches both edges of the blade |
intially, but shifts apart as the table travels along |
the rail, proceed to Method 2. |
6. Tighten the fasteners at both ends of the left rail. |

7. Adjust the right guide rail so that the horizontal rollers |
underneath the table engage the rail as shown in |
Figure 22. In most cases the rollers will not have to |
be vertically adjusted. Spacing between rails must |
be equidistant at all points to ensure that they are |
parallel. Once adjustments are made, lightly tighten |
the fasteners on the right rail and move the table back |
and forth. If the table binds against the rail at any |
point, adjust spacing accordingly until the table moves |
smoothly. |
8. Tighten the fasteners at both ends of the right rail. |
If alignment has been achieved, do not proceed to Method 2.

4.Make sure the short portion of the straight edge is placed flush against the ruler guide. Adjust the left guide rail so that the front and rear edges of the blade touch the straight edge, although a tolerance of 0.1mm (.004 in.) between the front and rear edges is allowed. Perform this adjustment along the entire length of the straight edge.
5.Position the table as close to the user as possible. Place the straight edge flush against the ruler guide and blade. Without holding onto the straight edge, gently move the table towards therearofthesawandthenback. Observeanygapsthatmay appear between the straight edge and blade or between the straight edge and ruler guide. A gap exceeding the allowed tolerance means that the table is not moving parallel to the blade;hence, further adjustments as outlined below will be
