Craftsman CONTRACTOR 351.21833 - Manual (Page 10)

• If an adjustment is necessary, proceed as follows: Loosen
and remove the six socket pan head screws and the rear
panel (see Figure 22). Loosen the four hex head bolts on
the trunnion (see Figure 23) and shift trunnions until a
position is found where the saw blade is parallel to the
miter guage slots.
NOTE: Saw blade should also be centered within its table
insert opening.
• Tighten the hex head bolts and lock washers very securely.
This procedure will set the table and blade in parallel posi-
tion and prevent the trunnion from shifting.
NOTE: If you perform this adjustment, leave the back panel off
to perform rear rail assembly as described in the next section.
RAIL ASSEMBLY
Refer to Figures 24-29.
Tools Required: 13mm Open end Wrench
Hardware Required: Eight M8 x 28 hex head bolts, eight M8 x
25 hex head bolts, four M8 x 20 hex head bolts, twenty M8
lock washers, twenty M8 flat washers, sixteen M8 hex nuts
and four M8 acorn nuts. (Hardware bag #2).
• Insert two M8 x 28 hex head bolts and two M8 x 25 hex
head bolts into the T-slot of the right front guide rail. (The
two longer bolts will attach to the table; the two shorter
bolts attach to the table extension.)
• Attach right front rail to the table and right table extension
using flat washers, lock washers and hex nuts.
NOTE: Hand tighten all hardware during rail assembly. Do not
completely tighten hardware until all rails are mounted.
• Attach left front rail in the same manner. (The two longer
bolts attach to the table; the two shorter bolts attach to
table extension.)
NOTE: You may have to shift right rail as far right as it will go
to attach left rail.
• Position rails so that rails are butted together and the joint
between rails is aligned with right side of the blade. You
may need a mallet to lightly tap rails together. Make sure
rails are completely butted together at the joint.
• Use a straight edge as shown to check level and flatness
between right and left rail. Use a combination square as
shown to make certain that both front rails are parallel to
the table surface.
• After front rails are adjusted level and flat, tighten the
screws completely.
• Secure all hardware completely.
