Scale Adjustments; Bevel Scale; Mitre Scale - DeWalt DW1251 Adjustment And Operating Instructions

7. SCALE ADJUSTMENTS
7.1 Rip Scale
The rip scale is located on the right side of the radial arm.
When the motor is positioned with the blade facing the
column, that is called the "in-rip" position and your
material must be fed through the blade from right to left.
When the motor is positioned with the blade facing the
operator, that is called the "out-rip" position and the
material must be fed from left to right.
The pointer indicating the ripping width on the scale is
adjustable as follows:
1. Place a board of known width (say about 24cm) against
the fence in its "rip" position (See Fig. 25).
2. Position the motor in its "out-rip" position (blade
towards the front of the machine) and move the yoke
assembly along the arm until the blade just touches the
forward edge of the material.
3. Loosen the two screws on the pointer assembly and
move the pointer until the edge of the "out-rip" pointer
lines up with the known width of the board on the lower
scale. Tighten the two screws.
4. Now remove the board and place the motor in its "in-
rip" position without moving the yoke assembly.
5. The "in-rip" pointer should now line up with the zero
position on the upper scale (adjust if necessary). The
position of the blade here indicates the ideal location
for the fence when "in-ripping".
Note: It is generally good practice to check the width of
cut with a tape rather than relying solely on the
scale, although the scale can be used with
complete confidence when making several cuts at
differing widths (i.e. +5mm or -7mm relative to the
first cutting width).
7.2 Bevel Scale
The bevel scale is located on the front of the motor'
beneath the switch handle. When the blade is positioned
for a vertical cut, the pointer should be at zero on the
scale. To adjust, loosen the screws retaining the pointer
disc, and move the disc until the pointer points to '0' and
then retighten the screws.
7.3 Mitre Scale
The mitre scale is located on the top of the arm beneath
the elevating handle. On top of the arm is a pointer which
can be adjusted to align with the '0'when the arm has
been correctly positioned and clamped for a straight
cross-cut. The scale is then marked 0°-50° to left and
right. The mitre latch engages with machined locations to
provide accurate 45°—0°—45° positioning.
