Drum Alignment - Jet 10 Plus Operating Instructions And Parts Manual

Drum Alignment

The sanding drum comes preset from the factory. If
a problem with the drum alignment occurs, follow
the instructions listed below.
Checking the Drum Alignment
1. Lift the knob (A, Fig. 6) to open the dust cover
and remove the abrasive strip. If you are
unsure how to do this, see the "Wrapping
Abrasive Strips" section in this manual.
2. Using a metal straight edge, or ruler, as a
thickness gauge (B, Fig. 6), insert the gauge
between the drum and the conveyor bed on the
outer end of the drum.
3. Open the dust cover and lower the sanding
drum while slowly rotating the drum by hand
until the drum lightly contacts the thickness
gauge.
4. Remove the thickness gauge and place it
under the drum at the opposite end. If the drum
does not contact the thickness gauge to the
same degree as the other end of the drum,
alignment is necessary.
Aligning the Drum
1. Loosen the two socket head button screws
(C, Fig. 7).
2. Lay the thickness gauge under the drum
lengthwise.
3. Adjust the knob, (D, Fig. 7) until the drum
contacts the gauge equally along its entire
surface. Turn
counterclockwise to lower the outboard end of
the drum, and clockwise to raise the outboard
end of the drum.
4. When the drum is parallel to the conveyor,
tighten the two socket head button screws.
Fine Tuning Drum Alignment
When sanding boards wider than the drum, drum
alignment is critical and must be adjusted slightly
higher on the outboard end. This will prevent any
ridges from developing in the stock. Always check it
on a piece of scrap wood, as follows, before
sanding the work piece.
Run a piece of scrap wood approximately 6" wide
by 16" to 18" long through the sander sideways so
that the end of the board extends past the end of
the drum.
Turn the board 180 degrees and sand the same
side without changing the sanding height.
the adjusting knob
If a ridge is visible where the drum overlaps, loosen
the two socket head button screws (C, Fig. 7) and
turn the adjusting knob (D, Fig. 7) slightly. Turn the
adjusting knob clockwise to lower the outboard end
of the drum and counterclockwise to raise it.
Tighten the two hex cap bolts. Repeat this process
until the ridge is gone and the entire board is
sanded.
