Figure 45: Mounting the Midway Fence
3. Tip the top of the rear support brackets (#9 in Figure 44) under the
upper
horizontal frame member (#8), raise
the fence, and push the lower ends of the rear support brackets down behind the
lower
horizontal frame
member. The nuts may have to be loosened slightly to perform this step.
4. Tap the entire fence system toward the center of the tool frame, and align (as closely as possible) the 45
°
angle of the aluminum extrusion (#5) with the 45
°
angle of the vertical tube at the center of the frame. To
assure a neat appearance, be sure the rear support brackets (#9) are flush top and bottom with the machine
frame tubes, and that they are at a 90
°
angle to the horizontal machine frame tubes.
5. Double-check the position of the complete fence assembly. Using the holes in the rear support brackets as a
template, drill six 7/32” (11.11mm)mounting holes in the machine horizontal frame tubes, and secure with six
self-tapping screws.
6. Repeat Steps 2 through 5 on the left-hand side of the frame.
7. Mount the wooden fence sections (#4), with the 45
°
angle ends toward the center of the machine, between the
aluminum extrusion sections and the cam-type spacers (#1). When not in use, the two wooden fence sections
can be stored in the material support channels (#15) on each side.
8. The friction fit of the wooden fence sections between the aluminum support bracket and the cam-type spacers
can be adjusted by turning the bolt heads with a wrench. This fit can be readjusted at any time without
realigning the fence system.
9. Align the fence system (see below).
Fence Alignment
1. Disconnect the power supply to the tool.
2. Remove the blade guard.
3. Slightly loosen the bolts that secure the aluminum extrusion (#5, Fig. 44) to the rear support brackets (#9), to
allow the extrusion to be moved up or down by tapping it with a mallet.
4. Tap the extrusion to align it evenly, 1/4” (6.35mm) above the
lower
horizontal frame member (#8).
5. Place a carpenter’s square on the wood fence, with the longer side on the fence and the shorter side against
the saw blade. Raise and lower the carriage to check if the saw blade maintains alignment with the edge of
the square. Gently tap the
outside
edge of the fence system to bring the wooden fence and the carpenter’s
square into alignment with the saw blade travel.
6. Reinstall the blade guard and reconnect the power supply.
7. Using a sample panel approximately 18” (458mm) wide and 40” (1,016mm) long, and a freshly sharpened saw
blade, trim 1” (25.4mm) off the end of the panel.
8. Remove the panel from the fence. Turn it around,
keeping the same edge down
. Trim 1” (25.4mm) off the
other end.
9. Measure the top and bottom of the piece. When the measurements are the same, or within the tolerance of
