UNPACKING YOUR SUPERBRUSH
Your SUPERBRUSH sander has been shipped completely assembled from the factory in a shroud on a pallet and shrink-wrapped in plastic. If any damage has occurred as a result of shipment, notify the trans­portation company as soon as possible and ask them to make an immediate inspection. Ask for a damage or loss report. Also notify your dealer of any loss or damage during shipment. See enclosed Warranty Statement.
Important: To avoid problems and potential damage to the machine, please read through the unpacking instructions below before proceeding to set up the machine in your shop.
1. Unbolt the machine legs from the shipping pallet. Install the rubber-based leveling feet or optional caster set on legs (Fig. 2). The feet and mounting hardware are in the STOP bag packed with your machine.
2. Loosen the hex nuts and set screws on the table support castings (Fig. 3) and on the motor support casting (7)(Fig. 5). The set screws on the table support castings have been tightened at the factory to eliminate free-play between the castings and the column tube during shipment. There are two table support castings on the S
UPERBRUSH,
one each for the right and left column tubes, and one motor support casting, all with set screws. Important: These set screws are tightened for shipping and must be loosened and readjusted before operating either the height adjustment mechanism or the brush speed control handle.
To properly adjust for operation, loosen each set
screw by first loosening its hex nut with a wrench
and then the set screw with an Allen wrench. Then retighten each set screw with your fingers so it only lightly touches the column tube. Hold each set screw in position with an Allen wrench and retighten the hex nut. Failure to follow these procedures may result in misalignment of the brush and/or the conveyor table.
Caution: Do not loosen the set screws on the
upper brush support castings.
Note: Some machines have a block of wood
under the main motor. If so, remove at this time.
3. Install the conveyor gear motor. Rotate the drive roller on the conveyor system so the flat part of the shaft is down. If necessary, connect the conveyor motor into an appropriate AC outlet (see page 6, “Making Electrical Connections”), to rotate the motor output shaft coupling so the set screws face downward. Disconnect electrical supply. Slide the conveyor motor assembly onto the drive roller shaft, aligning the shaft coupling and four mounting holes. Start the four 5/16” hex head bolts on the conveyor motor mounting bracket, but do not tighten yet.
Next, tighten the set screws in the coupling on the drive roller shaft, making sure they are on the flat of the shaft. Rock the drive roller while tight­ening the set screws to make sure they are centered properly on the flat. Install the bottom cover on the control box with two screws. Then connect power to machine and turn conveyor on full speed. While it is running, tighten the four 5/16" bolts to secure the conveyor motor assembly in place.

6 SUPERBRUSH OWNERS MANUAL
Your SUPERBRUSH sander was adjusted and aligned at the factory, and it has been carefully packed for shipment. However, because of possible stress during transit, the unit should be thoroughly checked before being put to use. This section covers the pre-operational checks you should make after unpacking and final assembly. Unnecessary problems can be avoided if these essential checks are performed before operating. Likewise, performing the recom­mended monthly maintenance procedures (page
11) will help assure trouble-free service.
MAKING ELECTRICAL CONNECTIONS
Po w er for the brush of your SUPERBRUSH is supplied by either a 5HP, single-phase, a 5HP, three phase, 208-230V motor; or a 5HP, three phase, 460V motor.
- Single phase motor: Protected by a thermal overload switch. On single phase machines, a NEMA 14-30 plug is provided. A 30 amp breaker is required.
- Three phase motor: No plug is provided. It can be hard wired to a main power source or a plug can be installed to be used with a receptacle.
- Three phase, 208V motors require a 20 amp breaker.

CONNECTING DUST COLLECTORS
Dust collection is necessary for all SUPERBRUSH models. The SUPERBRUSH 24 is equipped with one 4˝ diameter dust exhaust port at the top of the brush cover. The S
UPERBRUSH 36 has two 4˝ dust
exhaust ports.
To attach the S
UPERBRUSH to your collection
system, install 4˝ hose from your collector. (See Tips For Maximum Performance, page 12 of this manual.) The minimum recommended dust collector capacities at the dust port(s) are: S
UPERBRUSH 24:
600
CFM; SUPERBRUSH 36: 1,200 CFM. For best
results, follow the recommendations of the manufac­turer of your dust collection equipment. NOTE: Some applications will require more dust collection than the recommended minimum CFM.
CHECKING MACHINE FOR LEVEL
Proper leveling of the machine is essential to achieve continued maximum performance from the S
UPERBRUSH. Before making fine adjustments,
place the unit where it will be used in the shop. Then adjust the four leveling feet using a carpenter’s level both across the machine and in line with the machine, placing the level on the conveyor bed. If you have equipped your S
UPERBRUSH with the
optional caster set, do the same after positioning the machine where it will be operated most often. Mark the position of the legs on the floor with tape so it can be returned to the same position.
HEIGHT ADJUSTMENT
The table height is controlled by the height adjust­ment handle (10)(Fig.5). Turning the handle raises or lowers both sides of the table simultaneously by transferring the handle rotation through the miter gear and transfer rod assembly. One revolution of the handle raises or lowers the table 3/32 of an inch.
Before operating height adjustment, be sure both set screws located in both table support castings (Fig. 3) are loose to allow table support to slide on both column tubes. (These set screws are tightened for shipping.)
BRUSH ALIGNMENT
The brush must be parallel to the conveyor bed surface. Brush alignment can be visually checked by raising the tension rollers (Fig. 6) to their highest position (See Tension Roller Adjustment page 9) and raising the table so that the brush just contacts the conveyor surface. Brush contact should be

equal across the width of the conveyor. If the S
UPERBRUSH is properly leveled (See checking
machine for level), brush misalignment can be corrected by loosening the two set screws at the front of the outboard brush support casting (Fig.
5) and by raising or lowering casting to correct alignment. NOTE: Improper brush alignment will cause uneven results and lead to reduced brush life.
BRUSH SPEED ADJUSTMENT
The SUPERBRUSH is equipped with a variable speed drive which allows the brush to be operated anywhere between 400 and 1200 RPM. The faster the brush speed, the more aggressive the brush action. The brush speed control handle (1)(Fig. 5) raises or lowers the motor support casting (7)(Fig.
5) which activates the variable speed drive pulley.
RPM GAUGE
The RPM gauge (Fig. 8) displays the brush speed and is read where the scale intersects the top of the screw support casting. To calibrate the gauge, lower the motor to the lowest position. Loosen both hex nuts while holding set screws. Position the RPM scale so that “400” RPM intersects the top of the screw support casting (Fig. 8). Tighten hex nuts to hold gauge in this position.
CHECKING THE CONVEYOR BELT
Conveyor belt tracking adjustments may occasionally be necessary during break-in and normal operation to compensate for belt stretching. If adjustments are necessary, follow the instructions below:
Belt tracking adjustments are made while the conveyor belt is running. With the conveyor unit on and set at the fastest speed setting, watch for a tendency of the conveyor belt to drift to one side of the conveyor. To adjust the belt tracking, tighten the take-up screw nut (see Fig. 9) on the side the belt is drifting toward, and loosen the take-up screw nut on the opposite side. Adjusting the take-up screw nuts on either side of the conveyor allows belt tracking adjustments to be made without affecting belt tension. Adjust the take-up screw nuts only 1/4 turn at a time. Then allow time for the belt to react to the adjustments before proceeding further. Try to avoid over-adjustments. NOTE: Make sure wrench is below surface when brushing.

OPERATING YOUR SUPERBRUSH 9
Before using your SUPERBR USH, r eview the previous pages in this manual on initial set-up and adjustment. In this section, you will learn how to operate the machine. Note that connecting the machine to an adequate dust collection system is necessary before operating the unit.
The S
UPERBRUSH offers considerable control
and versatility through infinitely variable brush speed and feed rate. Experiment with both to find the proper sander performance for a given application. Varying the brush speed makes the brush more or less aggressive. Too aggressive on the brush may tend to raise the grain or round edges. Sometimes it may be better to make two or more passes with a less aggressive brush or setting.
The brush is rotating against the direction of feed; therefore, the leading edges of contours will receive more sanding than trailing edges. Stock should be reversed on subsequent passes to sand all surfaces. Stock may also be fed at an angle to allow more brush penetration on the sides.
BASIC OPERATING PROCEDURES
After you have connected the machine to a dust collection system, you are ready to begin to use the
SUPERBRUSH. The basic operating procedure for the S
UPERBRUSH models is as follows (Fig. 10):
1. Set depth of cut/bristle contact (page 10).
2. Set tension rollers to type of stock being sanded (See Tension Roller Adjustment below and Fig.
11)
3. Start sanding brush and select slow brush speed (page 8).
4. Start conveyor and select feed rate (page 10)
5. Start dust collector system.
6. Feed stock through unit.
7. Gradually increase brush speed until the desired finish is achieved (Fig. 8).
To feed stock through the S
UPERBRUSH, rest
and hold the stock to be sanded on the conveyor table,
allowing the conveyor belt to carry the stock into the brush. Once the stock is halfway through, reposition yourself to the outfeed side of the machine to receive and control the stock as it exits the unit.
TENSION ROLLER ADJUSTMENT
Spring loaded infeed and outfeed Tension Rollers (Fig. 11) are provided to maintain downward pressure on stock being sanded and to prevent slippage of the stock on the feed conveyor. When properly set, the Tension Rollers should engage or raise up about 1/8˝to accommodate the stock being brushed.
The Tension Rollers can and must be adjusted to accommodate flat surfaced stock vs highly contoured surface stock. If the Depth Gauge is properly calibrated (page 11), Tension Roller height is adjusted as follows: Note: Make sur e brush head is appropriate for application and contact.
Flat Surfaced Stock: Set the bottom of the tension rollers even with the bottom of the brush. Loosen the four Tension Roller locking knobs (Fig.
11). Raise the table to the “0” mark on the Depth Gauge. At this position, the brush and Tension Rollers are resting on the table surface. Lock all four Tension Roller knobs. For example, to brush a 3/4˝thick flat board, lower the table to 5/8˝on the Depth Gauge. This allows 1/8˝for Tension Roller engagement and 1/8˝brush penetration.

Contoured Surface Stock: (Example: A 3/4
˝
thick piece of molding with 3/8˝of molding relief.) Loosen all four tension roller locking bolts (Fig. 11). Adjust the conveyor table 1/4˝into the bristle tips (measure with a ruler from “0” mark on depth gauge.). At this position, the tension rollers are resting on the table surface and are positioned 1/4˝above the bottom of the brush. Lock all four Tension Roller locking bolts. To brush the piece, lower the table to the 3/8˝position on the Depth Gauge. This allows for 1/8˝of tension roller engagement and 3/8˝of brush penetration.
SELECTING STOCK FEED RATES
Selecting the proper feed rate is essential to proper brushing. Feed rate controls the duration of brushing on a particular spot. A slower feed rate allows more brushing to occur. In some instances, a slow feed rate and slow brush speed may produce the same result as a fast feed rate and fast brush speed. The variable feed rate control of the conveyor belt adjusts the load on the machine; it can be infinite­ly adjusted for maximum operating performance. A faster feed rate allows faster brushing but fewer revolutions of the brush per inch of sanding. A slower feed rate provides more revolutions of the brush per inch of sanding (Fig. 10).
The best feed rate will depend on a number of factors, including type of stock, brush, depth of cut used, and whether the stock is fed directly in line with the conveyor bed or at an angle.
When using a wire brush for “distressing” wood, a brush speed of 400-600 RPM with light contact of bristles and a moderate feed rate generally leaves the best finish.
SETTING BRUSH DEPTH OF CUT/CONTACT
SuperMax Tools tests sample applications for all customers before selling a S
UPERBRUSH. We rec-
ommend following the suggest RPM, contact and conveyor settings outlined in the sample letter. If you have questions about your application(s) or your needs change, please contact SuperMax Tools for updated information or new sample testing, as brush types, materials, etc. may have changed.
The information and suggestions listed below are not specific to any application and may have changed since printing. Please call SuperMax Tools if you have questions.
When a nylon or wire brush is worn and needs changing, the bristles will either have fractured and the brush head looks “bald” or the bristle length has worn and the bristles are too short for effective brushing.
When an abrasive or cloth brush is worn, the brushing material will become smooth or the brush will be considerably smaller in diameter as compared to new. Cloth brush heads may only need cleaning to rejuvenate the cloth. Please call SuperMax Tools if you have any questions. Brush life can vary considerably, due to RPM, contact, type of brush, and material being brushed.

OPERATING YOUR SUPERBRUSH 11
Many types of brush heads may be rewound with new bristles or re-equipped with new brush material. Please contact SuperMax Tools if you have questions about a new or re-wrapped brush head.
Some types of brush heads, some fladder brushes, for example, will allow changing of the brush material by the operator, thus eliminating the need to send the brush head out for re-wrapping. Please call SuperMax Tools if you have any questions about re-wrapping a brush.
When using a wire brush for “distressing” wood, slowing brush RPM, using light contact and a moderate feed rate generally will give the best finish and longest brush life.
When using a wire brush on metal, it is important to use a light contact of the bristle tips.
Wire brushes frequently flipped end for end, to keep the wire from bending in one direction, will extend brush life. Caution, if you choose not to flip the brush frequently, it is better not to flip the brush at all.
Nylon Brushes. “Dr ess” tips of bristle brush peri­odically to maintain uniform brush wear and to expose new grit on the ends of the fiber.
Dressing Instructions: Staple a wide sheet of 60 grit sandpaper to a 1/2˝ thick flat wood surface. Strips of narrow sandpaper can also be used. Raise the brush so the tips of the bristles contact the sandpaper by 1/32˝. Set the conveyor speed to approximately 50% feed rate. Pass the abrasive loaded board through the machine until the brush fibers are sharp and even.
DEPTH GAUGE OPERATION
The depth gauge (see Fig. 11) measures the distance between the conveyor table and the bottom of the sanding brush. The sanding brush must be parallel to the conveyor bed surface. To calibrate the depth gauge, loosen the locking knob of the lower depth gauge casting so it rests on top of the table support casting. Raise the conveyor table until it touches the sanding brush. Then loosen the locking knob of the upper depth gauge casting and position the “0” mark of the scale even with the top of the lower depth gauge casting. Lock the upper depth gauge casting in position.
Once calibrated, the locking knob of the lower depth gauge casting can be loosened, allowing the lower depth gauge casting to ride on top of the table support casting. The depth can then be read where the scale enters the lower depth gauge casting. The depth gauge can also be used as a stop gauge as follows: Position the lower depth gauge casting along the scale to a desired finish thickness. Then lock the lower depth gauge casting with the lock­ing knob to prevent the conveyor table from being raised above that point
MONTHLY MAINTENANCE
For best results, perform the following r ecommended maintenance procedures on a monthly basis:
• Lubricate conveyor bushings and check for wear.
• Lubricate all moving parts, such as threaded
rods, washers, and column tubes.
• Clean dust from the conveyor belt.
• Blow dust from the motors.
• Check all set screws for tightness on parts such as
brush support castings, bearings, conveyor cou­pler, castings, pulleys, and miter gears.
• Clean brush, if applicable.
