REALIGNMENT
Method 1:
This procedure deals with the most common source of mis-
alignment 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 8.
3. Loosen the left and right guide rails by loosening the
fasteners found at the ends of the rail.
(see
figure 8)
The left rail should be slightly loose, so there is not too
much play during adjustments, but the right rail should
move freely.
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 between
the front and rear edges is allowed. Perform this adjust-
ment 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 the rear of the saw and then
back. Observe any gaps that may 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 in step 4 will be
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 de-
formed (i.e. bowed).
(see figure 9)
Perform test
cuts to determine if the rail should be replaced.
Typically a bowing displacement of up to 0.2mm
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 below.
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
10
. In most cases the rollers will not have to be verti-
cally adjusted. Spacing between rails must be equidis-
tant 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.
