is aligned with the blade.
Lock the table in the horizontal position. Mount the
rip fence on the table. Slide the rip fence next to, but
not touching, the blade. Lock the rip fence.
Check that the blade is aligned parallel with the rip
fence. If the blade and fence are not parallel, loosen
handle and knob (Key Nos. 12 and 13) on the trun-
nions (Key Nos. 2 and 5). Adjust the table position so
that the blade and rip fence are parallel. Secure the
table position by tightening handle and knob.
• After assembly, the table has to be aligned in order
to have the blade running through the center of the
slot in the table insert.
To move table sideways, loosen bolts (Key No. 3) on
the trunnions (Key Nos. 2 and 5). Move table to left
or right until blade runs through the center of slot.

tion while bolts are being tightened.
