Connecting Sander to a Dust Collector
Dust collection is necessary for all drum
sanders. The Performax 22-44 Plus is equipped
with a 4” dust collection port at the top of the
dust cover, and is designed to be used with a
standard dust collector, see Figure 13.
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.
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 sandpaper installed,
until it touches the conveyor.
2. Loosen hex nut (A, Fig. 14).
3. Adjust the pointer (B, Fig. 14) to read zero
and tighten bolt.
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 Performax 22-44 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
type of wood. For best results, use scrap wood
to practice sanding and to develop skill and
familiarity with the machine before doing finish
work.
A good rule of thumb when sanding with grits
finer than 80 is lower the drum so that it contacts
with work piece but still can 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 processed.
•
Hardness of the piece.
•
Feed rate of stock.
Establishing the Proper Drum Height
To establish the proper drum height, place the
board to be sanded under the drum and lower
the drum to the board thickness. Note:
Sanding drum should still rotate by hand.
Without changing drum height, finish feeding the
stock under the sander. Start sanding drum and
sand the board at that same position.
