Connecting Sander to a Dust Collector
Dust collection is necessary for all drum
sanders. T he P er formax 22- 44 P lus 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 coll ector , 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
m ore informati on.
Depth Gauge
The dept h gauge i ndic ates the distance f rom t he
bott om of the drum to the t op of the convey or .
1. Lower the drum, with sandpaper installed,
until it touches t he c onveyor.
2. Loosen hex nut (A, Fi g. 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
differ ent sandpaper grit s.
Se tting 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 t han 80 is l ower the dr um so that it c ontacts
with work piece but sti ll can be rot ated 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 proc essed.
• Hardness of the pi ec e.
• Feed r ate 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.
W ithout c hanging dr um height, finish f eedi ng the
stock under the sander. S tart sanding dr um and
sand the board at that same position.
