Extension Rollers
Speed Change Knob
The infeed and outfeed extension rollers support
the work as it goes through the machine.
TO MOUNT THE EXTENSION ROLLERS:
1. Thread three (3) 8mm setscrews into the
mounting bracket of the extension rollers.
The setscrew holes are located just below
the mounting holes. Just start them into the
holes for now.
2. Use three (3) hex bolts and washers to
mount the extension rollers. See Figure 5.
Make sure the roller assembly is oriented
as shown in Figure 6.
3. Position a straightedge on the table bed, so
it lays on the table and suspends over the
extension rollers. See Figure 6.

4. Move the edge of the mounting bracket
which is closest to the table bed up or down
until the first roller is even with the straight-
edge. Tighten the mounting bolts just
enough to hold that position. Now adjust
the three setscrews until the roller which is
furthest out is even with the straightedge. It
may require various combinations of loos-
ening and/or tightening the setscrews and
bolts to level the extension rollers with the
table.
5. Repeat steps 3-4 for the other extension
roller assembly.

Thread the black plastic knob onto the speed
change shaft located on the right hand side of
the machine. See Figure 4. Note that speed
changes should only be done with the motor
running. See the Operations section.
