Connecting Sander to a Dust Collector
Dust collection is necessary for all drum sanders.
The JET 10-20 is equipped with a 4”
dust collection
port in the back of the dust cover, and is designed
to be used with a standard dust collector as shown
in Figure 17.
JET offers a variety of Dust Collectors and Air
Filtration Units that will work nicely with your new
sander. Contact your local distributor for more
information.
Setting the Depth Gauge
The depth gauge indicates the distance from the
bottom of the drum to the top of the conveyor.
1. Lower the drum, with the sandpaper installed,
until it touches the conveyor.
2. Loosen the screw (B, Fig. 18).
3. Adjust the pointer (C, Fig. 18) to read zero and
tighten the screw.
Note: Depending on the desired accuracy, you
may need to repeat this process when installing
different sandpaper grits.
Setting the Depth of Cut
Adjusting the JET 10-20 for proper contact between
the abrasive and the stock is the most important
set-up procedure before operating the sander. It
may take some experimentation to determine the
proper depth of cut, given the variables of abrasive
grit and types of wood. For best results, use scrap
wood to practice sanding and to develop your skills
and familiarity with the machine before doing any
finish work.
A good rule of thumb when sanding with grits finer
than 80 is lower the drum so that it contacts the
work piece but can still be rotated by hand. When
using grits coarser than 80 grit, you can lower the
drum slightly more. However, a combination of
several variables will determine the proper depth of
cut to use, including the following:
!
Abrasive type and grit size.
!
Width of the piece being sanded.
!
Hardness of the piece being sanded.
!
Feed rate of the piece being sanded.

Establishing the Proper Drum Height
To establish the proper drum height, place the
board to be sanded under the drum and lower the
drum until it just touches the board.
Note: The
sanding drum should still rotate by hand. Without
changing the drum height, finish feeding the stock
under the sander. Start the sanding drum and sand
the board at that same position.
