Checks & Adjustments To Ensure Accuracy; Checking The Crosscut Travel Is - DeWalt DW1251 Adjustment And Operating Instructions

(v) Position the rear table boards and the fence (Fig. 8)
according to the material thickness and the type of
cut to be carried out.
Note: Never lift your Powershop by gripping
worktable or you risk twisting it and therefore
having to repeat the support bracket
adjustment procedure.
Mounting the Left-Hand Table Extension
Supplied with your Powershop is a left-hand table
extension to enable left-hand mitres to be carried out
satisfactorily.
The extension piece has the same depth as the main fixed
table and it attaches to the main machine as follows:
(i) Two metal support strips are each first secured to the
lower left-hand surface of the main worktable.
(ii) The extension table can now be fixed to the support
strips via the slotted holes using the bolts/self-
tapping screws provided.
FENCE LOCATIONS
The following illustrations show
where the fence must be to perform
each type of cut according to
thickness/width of material.

4. CHECKS AND ADJUSTMENTS TO ENSURE ACCURACY
4.1 Checking the
Crosscut Travel is
90° to the Fence
NOTE: In carrying out these checks and adjustments
you may find it more convenient to remove the
sawblade guard but remember that even a
stationary sawblade is sharp so take care not
to catch yourself on the teeth.
With the mitre latch (19) engaged, lock the clamp handle
(18) so that the sawblade is positioned for a straight 0°
cross- cut. Release the rip lock (7) and push the saw
carriage back so that the sawblade is just in front of the
fence. Then, by turning the elevating handle, lower the arm
so that the sawblade almost touches the surface of the
table in front of the wooden fence.
You are now in a position to check that the blade will cut a
line at 90° to the fence. Proceed as follows:-
(i) Place a rectangular piece of board in front of the
fence alongside the blade and lay a square flat on
top of it as shown in Fig. 9 with one side flat against
the fence and the other alongside the blade,
(ii) With the lower left-hand part of the blade guard
raised (or you may find it easier to remove the guard
completely) pull the saw carriage forward away from
the fence and check that the tooth on the blade
protruding furthest to the left (it will be either on the
leading or trailing edge of the blade) stays parallel to
the square as you pull the saw blade past the square.
If it is not running square, the arm is not at 90° to the
fence.
Note: At this stage, do not worry if the face of the
blade itself is not parallel with the square.
This will be adjusted next. We are now
merely checking that the line of the blade
across the table is at 90° to the fence.
