The Various Operating Adjustments Of Basic Machine; Arm Rotation; Blade Height; Yoke Assembly Rotation - DeWalt DW1251 Adjustment And Operating Instructions

10. THE VARIOUS OPERATING ADJUSTMENTS OF BASIC MACHINE
The numbers in bracki
10.1 Arm Rotation
refer to those in the ''Controls" illustrations on page 2
The radial arm rotates to right or left for mitre cuts.
Release the mitre clamp handle (18) and the mitre latch
(19). Then swing the arm (2) right or left to the required
angle. Then lock the clamp handle(18).
The calibrated mitre scale (1) is just below the elevating
handle and indicates the angle of the arm relative to the
'0' straight cross-cut position.
The mitre latch (15) is only used to locate the arm in the
0° and 45° positions but adopt the habit of using the mitre
clamp handle also to secure the arm in this, as well as any
other, position.
10.2 Blade Height
The Radial Arm, and hence also the Saw blade, can be
raised or lowered by turning the elevating handle (6)
top of the column. Each complete rotation of the handle
moves the blade up or down by about 3mm.
10.3 Yoke Assembly
Rotation
Changing from cross-cut to the rip position takes only
seconds.
Release the rip slide bar (4) and the yoke clamp (10) and
then swing the yoke to right or left. The yoke locks
automatically at the four 90° positions, but remember to
always secure the yoke clamp also to maximise accuracy.
10.4 Blade Tilting
Turn the elevating handle to raise the sawblade well above
the table. Release bevel clamp (12) and bevel latch (1'
Tilt the motor to the desired angle on the bevel scale. With
clamp released, the latch will automatically locate in the
popular 0°. 45° and 90° angle positions.

registered as 0° on the mitre scale beneath the
elevating handle. Lock the mitre latch in position and
tighten the arm clamp handle.
Turn the elevating handle to lower the blade into
position behind the fence in its correct position for
the thickness of the material being cut (See Fig. 25)
To cut right through the material to be sawn it is
necessary to cut a shallow groove or kerf also in the
table top. If such a groove is not already there, switch
on the motor before the blade actually touches the
table surface so that it will cut into the table slightly
when lowering continues. Switch off the motor.
Place material on worktable and hold firmly against
the fence, keeping your thumb and fingers well away
from the path the sawblade will take.
Switch on motor and draw the sawblade through the
fence and across the material to make the cut. You
will find that you do not need to pull the motor
assembly forward - rather you will need to limit the
speed of travel in the cut otherwise the blade will
tend to jam.
After completing the cut, switch off and carefully
return the sawblade to its rest position behind the
fence.
