DeWalt DW1251 - 2 Adjusting Table Top Parallel with Arm

2. ADJUSTING TABLE TOP PARALLEL WITH ARM
To obtain accurate woodworking results, it is essential that
the table is completely parallel with the arm. The following
instructions explain how to do this:-
1. Prepare the base frame for the table boards by
setting the 2 angled support brackets (A-Fig. 1) on
each side of the frame so that the securing bolts (B)
and (C) are at the mid-point in the slotted holes. At
this stage the bolts should only be finger tight.
NOTE: Some models feature location pins which pre-
set the position of the brackets on the main frame.
On these models the bolts can already be tightened,
but you should still make the following checks. If they
indicate the location pins are wrongly positioned: tap
the pins out with a hammer and adjust via the slotted
holes in the support brackets.
Fig. 1
Use the tip of the motor spindle to act as a gauge to
check that the 2 support brackets are on the same plane,
as follows:
(i)
(iv)
(v)
(vii)
Rotate the elevating handle and raise the arm
enough to allow the motor to turn 90° into the vertical
position.
Release bevel latch and bevel lock and turn the
motor body until it is vertical. When it reaches the
vertical position press home the bevel latch so that
the motor is locked into position.
Release the arm clamp lever and the rip lock and
bring the motor to its fully forward position on the
arm.
Rotate the arm to bring the motor shaft to a position
directly over the left tablo support bracket.
Carefully lower the motor, by turning the elevating
handle, until the tip of the motor arbor just touches
the support bracket as shown. (Fig. 2)
Tighten the nut (C), rotate the arm to its 45° position
left and move the yoke assembly back along the arm
until the shaft is again over the support bracket (Fig.
3). If the motor arbor does not just touch the support
bracket here also, gently tap the bracket up or down
as required and then tighten nut (B) (Fig. 1). Having
tightened both (B) and (C). check once more that the
motor arbor just touches the upper surface of the
left-hand support bracket over its entire length. If it
does not, loosen the nuts and repeat the above
procedure.
Now move the arm to the right of the machine and
repeat this procedure to correctly secure the right-
hand support bracket.
Carry out a final check, running the tip of the motor
arbor along the top of both brackets and make sure
that all nuts are completely secure.
Now adjust the central table support strip in the same
way so that it is perfectly level with the two side
support brackets. (Fig. 4).
N.B. It is important not to change the height of the
arm during this adjustment procedure.
After completing the above adjustment, return the
motor to the horizontal position.
