Grounding Instructions
Caution: This tool must be grounded while in use to protect the operator from electric shock.
In the event of a malfunction or breakdown, grounding provi des a path of least resistance for electric
current to reduce t he ri sk of elec tric shock. This tool is equipped with an electric cord having an
equipment-gr ounding conductor and a grounding plug. The plug must be plugged into a matching outlet
that is properly installed and grounded in accor danc e with all local codes and ordinances.
Do not modify the plug provided. If it will not fit the outlet, hav e the proper outlet installed by a qualifi ed
electrician.
Improper connection of the equipment- gr ounding conductor can result i n a risk of electric shock. The
conductor, with insulation having an out er surface that is green with or without yellow stripes, is the
equipment-gr ounding conductor. If repair or replacement of the electric cord or plug i s necessary, do not
connect the equi pm ent- gr ounding conductor to a live terminal.
Check with a qualified electrician or service per sonnel if t he gr ounding instructions are not com pletely
understood, or if i n doubt as to whether t he tool is properly grounded. Use onl y three wir e ex tension cords
that have three-prong grounding plugs and three-pole receptacles that ac c ept t he tool’s plug.
Repair or replace a dam aged or worn cord im mediately.
115 Volt Operation
As received fr om the factory, your sander is ready to run at 115 volt operation. This sander, when wired
for 115 volts, is intended for use on a circuit that has an outlet and a plug t hat looks the one illustrated in
Figure A. A tempor ary adapt er , which looks like the adapter as ill ustr ated in Figure B, may be used to
connect this plug to a two-pole receptacle, as shown in Fi gur e B if a properly grounded outlet is not
available. The temporary adapter should only be used until a properly grounded outlet can be installed by
a qualified elec trician. This adapter is not applicable in Canada. The green colored rigid ear, lug, or
tab, extending f rom the adapter, must be connected to a perm anent ground such as a properly grounded
outlet box, as shown in Fi gur e B.

Assembly and Setup
If you purchased the optional Performax 22-44
Plus Stand refer its assem bly instruct ions bef or e
proceeding with the drum and conveyor
assembly.
1. Attach the knob (A , Fi g. 1) to t he handwheel
and tighten with a 9/16” wrench.
2. Place the conv eyor upside down on a table
surface.
3. Raise the drum by turning handwheel (B,
Fig. 2) clockwise.
4. Align four holes in the conv ey or with the f our
holes in the base of drum assembl y .
5. Secure conv eyor in place wit h four 5/16”-18
x 3/4” socket head cap screws (C, Fig. 2),
four 5/16” lock washers and four 5/16” flat
washers.
6. Plug motor cord into the control box
receptacle.
Drum Height Control
Drum height is controlled by the height
adjustment handle (B, Fig. 2). Turning
handwheel in a counter-clockwise direction
lowers the drum.
Turning height adjustment handwheel one
revolution lower s the dr um appr ox imately 1/16”.
Conveyor Belt Tension
Conveyor belt tension adjustment may be
necessary duri ng break i n peri od t o com pensate
for belt stretching.
If conveyor belt can be stopped by hand
pressure applied di rectly to the top of conveyor
bed, the belt is too loose. Insufficient belt
tension will cause slippage of conveyor belt on
the drive roller during sanding operation.
Excessive belt t ension can result in bent rollers,
bent take-up brackets and premature conveyor
belt wear.
After the PowerFeed unit has been installed
adjust the hex nuts (D, Fig. 2) on bot h sides of
the conveyor to obtain a tight, and equally
tensioned conveyor belt. Use the attached
wrench (E, Fig. 2) to adjust the hex nuts.
9
Conveyor Belt Tracking
Belt tracking adjustment may be necessary during
break-in period to compens ate for belt stretching.
Abrasive belt tension must be properly adjusted
before adjusting the tracking. Adjust the belt
tracking while conveyor belt is running at its fastest
speed.
Tighten hex nut (A, Fig. 3) on the side the belt is
drifting towards, and loosen hex nut on the opposite
side. Use the attached wrench (B, Fig. 3) to
adjust the hex nuts. Note: Adjustment should be
made in 1/4 turns of t he hex nut. Allow time for the
belt to rea ct to the adjustmen t . Do n ot over adjust .
Dust Cover
To open dust cover push in on the knob (C, Fig
3) and lift.
Checking Drum Alignment
The sanding drum comes preset from the
factory. If a pr oblem with drum alignment occ ur s
follow the below listed instructions.
1. Push in and lift knob (C, Fig. 3) to open
cover and remove abrasiv e strip. If you are
unsure how to do this see the “Wrapping
Abrasive Stri ps” section page 10.
2. Use a metal straight edge, or ruler as a
thickness gauge (D, Fig. 4). Insert the
gauge between the drum and convey or bed
on outer end of drum.
3. Open dust cover and lower sanding drum
while slowly rot ating drum by hand until the
drum lightly contac ts the thickness gauge.
4. Remove thickness gauge and place under
the drum at opposit e end. If 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 four hex cap bolt s (E, Fig. 5) two
in front and two in back.
2. Lay the thickness gauge under the drum
lengthwise.
3. Adjust the knob, (F, Fig. 5) until drum
contacts the gauge equ ally along i ts surface.
Turn the adjusting knob clockwise to raise
outboard end of drum, and counterclockwise to lower outboard end of drum.
4. When drum is parallel to the conveyor
tighten the four hex cap bolts.
10
Fine Tuning Drum Alignment
When sanding boards wider then the drum,
drum alignm ent is critical and must be adj usted
exactly l ev el to slightly high on the outboard end.
This should prev ent any ridges from developing
in the stock. Always test on scrap wood bef ore
sanding workpiece.
Run a piece of scrap wood approximately 6”
wide by 30” - 40“ t hrough the sander side ways
so that the end of board ex t ends past the end of
drum.
Turn board 180 degrees and sand the same
side of the workpiece without changing the
sanding height.
If a ridge i s vi sible due to drum overlap l oosen
the four hex cap bolts (A, Fig. 6) and turn the
adjusting knob (B, Fig. 6) slightly. Turn the
adjusting knob clockwise to raise the outboard
end of the drum. Ti ght en the four hex c ap bolts.
Repeat process until ridge i s gone and the entire
workpiece is sanded.
Wrapping Abrasive Strips
Note: When using Perform ax “Ready to Wrap”
and “Ready to Cut” abrasives, not all of the
steps below are necessary. You can use the
original abr asiv e belt that comes with t he sander
as a template for cutti ng y our own stri ps.
1. Mark and cut a taper at one end of the roll,
see Figure 7.
2. Square off the end of taper, see Figure 7.
3. Raise fastener lever (C, Fig. 8) on the
outboard end of drum, and insert the
tapered end of the abrasive (D, Fig. 8) so
that it uses most of the width of the slot.
Then release the cl ip lever to securel y hold
the strip end to the fastener.
4. The square edge of the abrasive strip should
follow the edge of the drum, see Figure 8.
11
5. Wrap abrasiv e strip around the dr um, being
careful not to overlap the windings, see
Figure 9.
6. Mark trailing end of strip where it crosses
the inboard end of drum ( A, Fig. 10) .
7. Remove the abrasive strip and cut a taper
as was done with the starting edge, see
Figure 7. Note: The taper on the rem aining
roll can be used as the t aper for the starti ng
edge of the next stri p to be cut.
8. Rewrap the drum starting at the lef t side as
described in steps 3-5 on the pr ev ious page.
9. Raise fastener lever completely on the
inboard end of drum, and insert the t apered
end of abrasive strip through the sl ot into the
take-up fastener.
Important: Position the abrasive strip with
sufficient room between the inside of slot and
the tapered end of strip to all ow it to be pulled
into the drum as needed, see Figure 11.
The abrasive str ip m ay stretch enough i n use to
allow the take-up fastener to reach its lowest
position so it no longer is able to maintain
tension of the strip. If this occurs, it will be
necessary to reset the take-up lever by raising it,
pushing the strip end into the slot, and then
releasing the cli p lever.
The Tuf Tool (B, Fig. 12) can also be used to
hold the take- up fastener in place while you feed
the sandpaper through the slot. Hold the Tuf
Tool at an angle to insert t he end into t he hole in
take-up f astener. P ull the t ool up and r otat e 90°
to clamp onto the drum, see Figure 12.
12
Connecting Sander to a Dust Collector
Dust collection is necessary for all drum
sanders. The Performax 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 col lector, 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 informati on.
Depth Gauge
The depth gauge indi cat es the distance f rom t he
bottom of the drum to the t op of the convey or .
1. Lower the drum, with sandpaper installed,
until it touches the c onveyor.
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 t his 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 result s, 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 t hat it contacts
with work piec e 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 gri t size.
• Width of the piece being processed.
• Hardness of the piec e.
• 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 changi ng drum height, finish f eedi ng the
stock under the sander. St art sanding drum and
sand the board at that same position.
13
Selecting SANDSMART™ Feed Rates
Begin experimenting with the feed rate set at
about 40%-50% of maximum. The best feed
rate will depend on a number of factors,
including type of stock, grit and depth of cut
used, and whether the stoc k is feed directly inline wit h the conveyor bed or at an angle. If a
“rippl e effect” or inconsistent fi nish is observ ed,
slow down the f eed rate. If the fi nish is smooth
and consistent and the sander is not
overworking, experiment using a faster feed
rate.
The SandSmar t c ontrol ( A, Fi g. 15) cont i nuously
monitors the load on the drum motor, and
automatically regulates the speed of the
conveyor m otor to maintai n the highest f eed r ate
without overl oad. If the load on the drum motor
increases, the SandSm art control will decrease
the conveyor feed rate and will stop the
conveyor under extreme conditi ons. If the load
on the drum decreases, the SandSmart control
will incr ease the feed rate but will not increase it
faster than the m anual setting on the switch dial.
The best and most consistent finish will be
achieved if the convey or does not c hange speed
during operat ion. W hen the “red” indicator light
(B, Fig. 15) comes on, the SandSmart control
has detected too gr eat a depth of cut and/ or too
fast a feed rate. This change in conv ey or speed
may affect the finish surface. If the finish is
affected, make another sanding pass without
changing any settings. If the finish is still
affected, make adjustments by slowing the
conveyor and/ or decreasing the depth of cut and
run the stock thr ough again.
Abrasives
The abrasive material you choose will have a
substantial effect on the performance of your
sander. Variations in paper type, weight,
coating, and dur ability all contribute to achiev ing
your desired finish. For the best sanding resul ts,
Performax offers premium abrasives that have
been tested and cert ified for lowest ov erall cost
and maximum performance. Genuine
Performax abrasives are available in pre-cut
“Ready- to-Wrap” lengths or in the convenient
pre-mark ed “Ready-to-Cut” box.
Selecting Drum Abrasives
It is important to select the proper grit of
abrasives for the type of sanding being
performed t o achiev e maximum sanding resul ts.
As with any sanding operation, first begin
sanding with coarser grit, depending on the
roughness of t he stock, or the amount of stock
to be removed. T hen progressiv el y work toward
finer grits. The chart below shows the general
uses for the v ari ous grit s. Perf orm ax off ers strip
rolls in the eight dif ferent abrasive grits shown.

Sele c ting Abra sive Gr its
The amount of stock to be removed i s a major
consideration when choosing the grit grade to
start with. Grits of 24, 36, 50, 60 and 80 are
primarily designed for stock removal. Grits 24
and 36 will remove the most material in one
pass, whether you are d oing abrasiv e planning,
cleaning up glued panels, or flattening stock.
Grits from 100 through 220 are primarily
finishing grits designed to remove the scratch
pattern from the previous grit used. For best
results, never skip more than one grit grade
when progressing through a sandi ng s equenc e.
For fine work, such as furniture, try not to skip
any grit gr ades during the sanding pr ocess. In
general, premium quality abrasives such as
genuine Performax abrasives will produce a
better finish with a less noticeable scratch
pattern. Note: Grits that are too fine can
sometim es burnish the wood a nd leave a gl ossy
surface that will not accept stains ev enly. This
will vary by type of wood. Oak, for example, is
susceptible to burnishing because of its open
pores.
Stock Feeding Angle
The optimum stock feeding angle, when
sanding, is at a 60 degree angle (Fig. 13).
However, even a sl ight stock feeding angl e will
provide more effective stock removal, less
loading of abrasives, longer abrasive life,
potentially faster feed rates and reduced m otor
loads.
When finish sanding the workpiece should be
fed through in li ne wit h the grai n on the fi nal one
or two passes for the optim um finish.
Multi pl e- Piece Sandin g Runs
When abrasiv e planing (or t hickness sanding) a
run of sim ilar pieces that you want to h ave the
same thick ness, it is best t o sand all the pi eces
at the same time. This way you will be able to
determine the thickness of the thinnest piece
and process all pieces to that same thickness.
Be aware that the sander will remove cups and
crowns in the work piece; consider this when
measuring the processing stock to the same
thickness.
Edge Sanding
When edge sanding, the Performax sander will
mimic the opposite edge of the stock which is
lying on the conv eyor belt. Because of this, it is
important for the stock edge to have been r ipped
at the proper angle to the face before the
sanding process. When edge sanding stock that
is less than 3/4” wide, or m ore than 2” hi gh, it is
good procedure to stack and clamp several
pieces together to prevent them from sl ipping, or
tipping.
Sanding Imperfect Stock
When sanding stock with a c up or crown, place
the crown up. Thi s will stabilize the stock to hel p
prevent ti pping or roc ki ng duri ng sanding. ( Af ter
the crown has been rem oved and t he top is fl at,
turn the stock ov er and sand the oppo site side. )
To avoid personal inj ury, t ake speci al c are when
sanding stock that is twisted, bowed or
otherwise v aries in thickness f rom end to end. If
possible, support such stock as it is being
sanded to keep it from slipping, or tipping. Use
extra rol ler stands, hel p from another person, or
hand pressure on the stock to minimize
potentially hazardous situations.
Face Frames and Raised Panel Doors
It is v ery important t o have the proper abrasive
contact when doi ng this type of san ding. If t he
sander is set t o take an ex cessive depth of cut,
the result can be a gouge, or dip as the drum
goes from sanding the rails at full width to
sanding just a f ew inches of width on the sti les.
To prevent this problem, make sure that when
using abrasives fi ner then 80 grit the drum is in
contact wit h the wood, but can sti ll be spun by
hand.
Monthly Maintenance
For best results, perform the following
recommended maintenance procedures on a
monthly basis:
• Lubricate conv eyor bushings and check for
wear.
• Lubricate all movi ng parts, such as threaded
rods, washers, and bushings.
• Clean sawdust from the conveyor belt and
sandpaper.
• Blow dust f rom motors and switches. B low
dust from the inside of sanding drum to
prevent vibration. Be careful not to disturb
the drum balanci ng weights.
• Check all setscrews for tightness on parts
such as bearings, conveyor and couplings.
15
Cleaning Abrasive Strips
A sandpaper cleaning stick may be used to
remove deposits and help extend sandpaper life.
To use, operate the sanding drum with the dust
cover open.
Caution: For your own safet y, always wear eye
protecti on while performing sandpaper cleani ng,
and take all precautions to avoid any c ontact of
hands, or clot hing with uncovered drum s. Hold
the cleani ng stick against t he rotating dr um and
move it along t he drum surface. It i s good idea
to use a shop brush or air nozzle to rem ove any
cleaning stick crumbs from the drums before
resuming sanding oper ations.
Cloth-backed abrasives can be cleaned by
soaking in pai nt thinner, or mineral spiri ts for 20
minutes to one hour. Then use a nylon brush to
remove any buildup.
Stretching Abrasive Life
Abrasive lif e can also be inc reased by rem oving
the abrasive strip from the drum and r eversing it.
To do this, r emove the strip and use what was
the trailing end as the starting end on the left
(outboard) si de of t he drum . Rev er sing the st ri p
will provide a fresh set of cutting edges on the
drum.

You can also adjust the spring loaded screws,
found on the pressure roller brackets, to
increase or decrease rol ler pressure. If y ou are
having snipe marks at the leading end of the
board adjust the outfeed roller pressure. If the
snipe mark occurs on the trailing end of the
board adjust infeed roller pressure.
Drum Height Control Adjustment
If the height control mechanism does not
operate easil y or smoot hly, or ther e is ex cessiv e
vertical movement or deflection of the drum
carriage, perform the following adjustments.
1. Tighten all four lock nuts (F, Fig. 18) and
