Keep This Manual Handy For Quick SUPERMAX OWNER'S

SETTING UP YOUR SUPERMAX 7are not recommended, but if used, should be 10gauge wire for lengths up to 10' and 8-gauge wirefor longer lengths.Note: The Intellisand Control (Fig. 6) protects both main drum and conveyor motors frommost overload situations. The conveyor motor forfeeding stock is infinitely variable from 0-15ft/ min. If the load on the drum motor reaches itsoptimum, the Intellisand Control will automatically slow the feed rate of the conveyor. When theload is decreased on the main motor, the feed ratewill automatically increase but never exceed themanual setting on the dial.CONNECTING DUST COLLECTORSDust collection is necessary for all SUPERMAxsanders. The SUPERMAx50x2 is equipped withthree 4" -diameter dust exhaust pons at the top ofthe dust cover.To attach the SUPERMAxto your collection system, install 4" hose from your collector using onehose per port. (See 1ips For MaximumPerformance, page 17 of this manual.) The minimum recommended dust collector capacity at thedust ports is 1,800 CFM. For best results, followthe recommendations of the manufacturer of yourdust collection equipment.CHECKING MACHINE FORINTELLISANDCONTROLLERFig. 6.

Then, holding up the fronttension roller, check at inboard side (Fig. 7) of thedrum to see that the drum is parallel to the table.LEvELProper leveling of the machine is essential toachieve continued maximum performance fromthe SUPERMAx.Before making fine adjustments,place the unit where it will be used in the shop.Then adjust the four casters and mounting hardware using a carpenter's level both across themachine and in line with the machine, placing thelevel on the conveyor bed. Mark the position ofthe casters on the floor with tape so it can bereturned to the same position.CHECKING DRUM ALIGNMENTYour SUPERMAxwas shipped from the factorypreadjusted with the drums aligned to the conveyor table. Unless the machine was stressed duringshipment, only fine adjustment should be necessary. Minor alignment corrections can be donewithout relieving V-belt tension or adjusting thetension rollers, but should be done without anyabrasive strips attached to the drums.Front Drum: Using a flat piece of wood or metalas a thickness gauge, insert it between the convey-Fig. 7.

Rear drum adjustment indicator.If it is not, disengage the right (inboard) miter geartance, tum the knob clockwise to reveal the setscrew on the shaft collar below the bracket, thenloosen the set screw. Making sure the adjustmentknob is tightly seated on top of the bracket, raisethe shaft collar up against the bracket from belowand retighten the set screw. Note: The nut of therear bolt on the rear (secondary) drum bearingbracket should be backed off a quarter-tum frombeing fully tightened. This allows the lock washerto be depressed slightly but not completely. This isthe pivot point for the rear drum.(see Fig 8), finely raise or lower the right(inboard) side of the table to achieve parallel alignment of the front (primary) drum. The distancebetween the conveyor table and both sides of thefront drum should be the same. Reinstall the mitergear, aligning the set screw to the flat of the shaft.Rear Drum: Before altering this conveyor tableposition, also check to see that the rear drum islikewise parallel to the conveyor table, with bothsides at the same height above the table. Using thesame thickness gauge, check both sides of the reardrum from the rear of the machine while holdingup the rear tension roller. Adjustment of the reardrum is done by using the right and left drumadjustment knobs (see Fig. 9).After the rear drum is adjusted, it is important toreset the rear drum adjustment indicators to zeroon both sides. Set the secondary drum adjustmentindicators by loosening hex nut, then moving theindicator scale so that the zero mark is directlyunder the needle, and retightening the hex nut(see Fig. 9). Zero the indicator for other side ofdrum. Take care not to overtighten the hex nut ofthe indicator. This can flare the brass bushing andrender the indicator inoperable.Check that the secondary drum adjustmentknobs tum with a slight resistance to avoid anymovement during operation. To adjust knob resis-CHECKING THE CONVEYOR BELTConveyor belt tension and tracking adjustmentsmay occasionally be necessary during break-in andnormal operation to compensate for belt stretching.Belt Tension.To adjust the tension of the conveyor belt, first adjust the take-up screw nut (see Fig.10) on both sides of the conveyor to obtain approximately equal tension on both sides of the belt whentaut. Insufficient belt tension will cause slippage ofconveyor belt on the drive roller during sandingoperation. The conveyor belt is too loose if it can bestopped by hand pressure applied directly to the topof the conveyor belt while running at full speed.Excessivebelt tension can result in bent rollers, orpremature wearing of the bronze bushings or belt.BeltTracking.Belt tracking adjustments are madewhile the conveyor belt is running. After the properbelt tension is obtained (see above), turn the convey-

To adjust the belt tracking,tighten the take-up screw nut (see Fig. IO) on theside the belt is drifting toward, and loosen the takeup screw nut on the opposite side. Adjusting thetake-up screw nuts on either side of the conveyorallows belt tracking adjustments to be made withoutaffecting belt tension. NOTE: Adjust the take-upscrew nuts only 1/4 turn at a time. Then allow timefor the belt to react to the adjustments before proceeding further.

Thenhold each set screw in position with an Allenwrench and tighten the hex nut.Check the operation of the height adjustmentmechanism. If it does not operate smoothly or easily, further adjustments may be necessary. Refer tothe servicing section of this manual, which beginson page 25, for further adjustment procedures.CHECKING TABLE HEIGHT CONTROLSThe table height and depth of cut is controlled bythe height adjustment handle (see Fig. 11). Turningthe handle raises or lowers both sides of the tablesimultaneously by transferring the handle rotationthrough the miter gear and cross bar assembly.Important Before using the height adjustment,be sure to loosen both the set screws located on thefront of both table support castings (see Fig. 3 andFig. 11) to allow the table support to slide on bothcolumn tubes. These set screws are tightened forshipping and must be loosened and readjusted toallow the table support castings to move freely onthe column support tubes. Readjust the set screwsjust so they eliminate free-play between the tablesupport casting and the column tube. To properlyMONTHLY MAINTENANCEFor best results, perform the following recommended 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 sawdust from the sandpaper and the conveyor belt Blow dust from the inside of sanding drums andthe motors. Check all set screws for tighmess on parts such astable support castings, bearings, conveyor coupler,castings, pulleys, and miter gears.

Proper attachment of the abrasivestrip to the drum is criticalto achievingtop performance from your Performaxdrum sander.Abrasivestrips do not have to be pre-measured.The end of theroll is first tapered and attached to the left (outboard)side of the drum. Then the strip iswrapped aroundthe drum, and the second taper is made for attachment to the right (inboard) side of the drum. To attacha strip to the drum, followthe procedure below.1. Mark and cut a taper at one end of the roll asshown in Fig. 12a. Becausethe tapered end should use .most of the left (outboard) slot width, its end must be ··trimmed (Fig. 12-b and 12-c). Raisethe clip leveronthe left (outboard) side of the drum (Fig. 12-d). Insertthe tapered end throughthe slot and into the fastenerso that it uses most of the width of the slot. Releasethe clip lever to securelyhold the strip end in the fastener.2. Wrap the strip around the drum, being carefulnotto overlapthe windings.The tapered cut of the stripend should followthe edge of the drum. Continue towrap the abrasivein a spiralfashionby rotating thedrum with your left hand and guiding the strip withyour right hand (Fig 12-e). Successivewindings of thestrip should be flushwith previouswindingswithoutany overlap.3. Mark the trailingend of the strip where it crossesthe right (inboard) end of the drum (Fig. 12-f). Fromthis point, cut a taper as was done with the startingedge of the strip. Wrap the tapered strip on the drumover the slot on the inboard side. If the tapered endextends beyond the slot more than 1-11/4" trim theexc.essbefore insertinginto inboard fastener.

12 SUPERMAX OWNER'S MANUALOPERATING YOUR SUPERMAxBefore using your SUPERMAx50x2 drum sander,review the previous pages in this manual on initialset-up and adjustment. In this section, you will· learn how to operate the machine. Note that connecting the machine to an adequate dust collectionsystem is necessary before operating the unit.BASIC OPERATING PROCEDURESAfter you have selected and installed abrasivestrips, and connected the machine to a dust collection system, you are ready to begin to use theSUPERMAx50x2. The basic operating procedure isas follows:1. Set depth of cut.2. Start drums.3. Start conveyor and select feed rate.4. Start dust collector system.5. Feed stock through unit.IntellisandTo feed stock through the SUPERMAx,rest andhold the board to be sanded on the conveyor table,allowing the conveyor belt to carry the board intothe drums. Once the stock is halfway through,reposition yourself to the outfeed side of themachine to receive and control the board as it exitsthe unit.HEIGHTADJUSTMENTHANDLE\IntellisandSuperMax 50 X 2 IntellisandFig. 13. SUPERMAxoperating controls.

OPERATING YOURSUPERMAXUSING THE MOTORIZED HEIGHTADJUSTMENTThe two rocker switches located at the bottomfr?nt of the control box assembly are for usj.ngwith the motorized height adjustment (Fig. 13).The switch on the right (as you face the sander) isfor moving the conveyor up or down to reach adesired height. The switch on the left is forchanging conveyor movement from fast mode toslow mode. The "slow" up mode (raising conveyor), should be used for establishing drum contactand adjusting depth of cut per pass. Hand cranking can also be used to establish depth of cut andto adjust depth of cut per pass. Do not use fastmode for fine tuning adjustments or setting thedepth of cut.See "SETTINGTHE DEPTH OF CUT" below toestablish proper contact of abrasives to stock.The fuse holder between the two switches uses aone amp fast-acting fuse. The fuse will blow if anexcessive load is placed on the conveyor or if theheight adjustment is operated beyond its workingrange. CAUTION: The fuse may not blow beforecausing damage to the sander if operating beyondits range.The motorized height adjustment can bebypassed by simply turning the height adjustmenthandle by hand. Hand cranking may feel stiff butthe resistance from the gear motor is normal. Donot attempt to raise conveyor bed if the conveyoris touching the drum or if stock is caught betweenthe drum(s) and conveyor system.The speed of the "slow" mode can be fine tunedusing a screw driver or coin on the exposed slotlocated under the housing containing the switches(Fig. 45A). Turn the slot until a desired speed isobtained to use for fine tuning adjustments.CAUTION: Do not loosen the Phillips head boltlocated in front of the adjustment slot.SETTING THE 0EPTII OF CUTDetermining the depth of cut is the most important set-up procedure before operating theSUPERMAx50x2 sander. It may take some experimentation to determine the proper depth of cut,given the variables of abrasive grit, type of wood,and feed rate. For best results, use scrap wood topractice sanding and to develop skill and familiari-13ty with the machine before doing finish work.Use only the slow mode of the electric heightadjustment or the hand crank for setting the depthof cut or to fine tune adjustments. The fuse for, the electric height adjustment may not blowbefore causing damage to the sander if operatingbeyond its range. Do not use fast mode for finetuning adjustments or setting depth of cutA good rule of thumb when sanding with gritsfiner than 80 is to raise the conveyor table so thedrums contact the workpiece but still can be rotated by hand. When using grits coarser than 80 grit,you can sometimes raise the conveyor table slightlymore. However, a combination of several variableswill determine the proper depth of cut to use,including the following:1. Abrasive type and grit size.2. Width of the piece being processed.3. Hardness of the piece.4. Feed rate of the conveyor belt.The depth of cut for the primary drum is adjusted by the table height adjustment handle or electric controls. The depth of cut for the secondarydrum is controlled by the two adjustment knobs(analog indicators) located on both sides of thedrum. The drum adjustment knobs allow properdepth of cut with virtually any abrasive grit combinations on the drums. The two drums are normal-Fig. 14. Rdative positions of dual drums.
