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 as it will be adjusted last.
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 deformed
(i.e. bowed).
(see
figure
12)
Perform test cuts
to determine if the rail should be replaced. Typi-
cally a bowing displacement of about 0.2mm will
not affect cutting accuracy.
B. If the straight edge touches both edges of the
blade initially, 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

8. Tighten the fasteners at both ends of the right rail.
If alignment has been achieved do not proceed to method
2.
(see
figure
10)
Method 2:
This procedure corrects another source of misalignment
that occurs when the table’s orientation is not parallel with
the guide rails.
1. If the table shifts to the right as it travels away from the
user, a shim needs to be added to the guide roller fur-
thest from the ruler guide. On the other hand, if the
table shifts to the left, a shim needs to be added to the
guide roller closest to the ruler guide. Remove the ap-
propriate guide roller to insert a shim between the roller
and table, then reattach.
on the severity of the shift, more than one shim may be
required.
