SAFETY

For Machines Mfd. Since 9/20

Additional Wide Belt Sander Safety

Serious injury or death can occur from getting hands trapped between workpiece and conveyor table and being pulled into machine, or becoming entangled in rotating parts inside machine. Workpieces thrown by sander can strike nearby operator or bystanders with signiﬁ cant force. Long-term respiratory damage can occur from using sander without proper use of respirator. To reduce the risk of these hazards, operator and bystanders MUST completely heed the hazards and warnings below.

Feeding Workpiece. Placing fingers between

workpiece and conveyor can result in pinching injuries, or possibly getting fingers trapped and pulled into sanding area of machine. DO NOT place fingers under bottom of workpiece while feeding it into sander.

Sanding Dust. Sanding creates large amounts of

fine airborne dust that can lead to eye injury or serious respiratory illness. Reduce your risk by always wearing approved eye and a respirator when sanding. Never operate without adequate dust collection system in place and running. However, also remember a dust collection system is not a substitute for using a respirator.

Avoiding Entanglement. Tie back long hair,

remove jewelry, and do not wear loose clothing or gloves. These can easily get caught in moving parts. Never reach inside machine or try to clear jammed workpiece while machine is operating. Keep all guards in place and secure.

Power Disconnect. An accidental startup

while changing sanding belts or performing adjustments or maintenance can result in entanglement or abrasion injuries. Make sure machine is turned OFF, disconnected from power and air, and all moving parts are completely stopped before changing belts, doing adjustments, or performing maintenance.

Kickback. Occurs when a workpiece is ejected

out the front of sander at a high rate of speed toward operator or bystanders. To reduce risk of kickback-related injuries, always stay out of workpiece path, only feed one board at a time, and always make sure pressure rollers are properly adjusted below sanding roller. Never sand workpiece below minimum specifications listed in Product Specifications.

Sandpaper Contact. Rotating sandpaper can

hands away from rotating sanding drum(s) during operation. Never touch moving

Like all machinery there is potential danger when operating this machine. Accidents are frequently caused by lack of familiarity or failure to pay attention. Use this machine with respect and caution to decrease the risk of operator injury. If normal safety precautions are overlooked or ignored, serious personal injury may occur.

Before installing the machine, consider the availability and proximity of the required power supply circuit. If an existing circuit does not meet the requirements for this machine, a new circuit must be installed.

To minimize the risk of electrocution, fire, or equipment damage, installation work and electrical wiring must be done by a or qualified service personnel applicable electrical codes and safety standards.

The full-load current rating is the amperage a machine draws at 100% of the rated output power. On machines with multiple motors, this is the amperage drawn by the largest motor or sum of all motors and electrical devices that might operate at one time during normal operations.

The full-load current is not the maximum amount of amps that the machine will draw. If the machine is overloaded, it will draw additional amps beyond the full-load rating.

If the machine is overloaded for a sufficient length of time, damage, overheating, or fire may result—especially if connected to an undersized circuit. To reduce the risk of these hazards, avoid overloading the machine during operation and make sure it is connected to a power supply circuit that meets the requirements in the following section.

Note: The circuit requirements in this manual are for machine will be running at a time. If this machine will be connected to a shared circuit where multiple machines will be running at the same time, consult a qualified electrician to ensure the circuit is properly sized.

A power supply circuit includes all electrical equipment between the main breaker box or fuse panel in your building and the incoming power connections inside the machine. This circuit must be safely sized to handle the full-load current that may be drawn from the machine for an extended period of time. (If this machine is connected to a circuit protected by fuses, use a time delay fuse marked D.)

Leveling machinery helps precision components, such as bed ways, remain straight and ﬂat during the lifespan of the machine. Components on an unleveled machine may slowly twist due to the dynamic loads placed on the machine during operation.

For best results, use a precision level that is at least 12" long and sensitive enough to show a distinct movement when a 0.003" shim (approximately the thickness of one sheet of standard newspaper) is placed under one end of the level.

See the ﬁgure below for an example of a high precision level.

Generally, you can either bolt your machine to the ﬂoor or mount it on machine mounts. Although not required, we recommend that you secure the machine to the ﬂoor and level it while doing so. Because this is an optional step and ﬂoor materials may vary, hardware for securing the machine to the ﬂoor is not included.

Dust Collection

This machine creates a lot of wood chips/ dust during operation. Breathing airborne dust on a regular basis can result in permanent respiratory illness. Reduce your risk by wearing a respirator and capturing the dust with a dust-collection system.

Minimum CFM for Model SB1096: 1800 CFM

Do not confuse this CFM recommendation with the rating of the dust collector. To determine the CFM at the dust port, you must consider these variables: (1) CFM rating of the dust collector, (2) hose type and length between the dust collector and the machine, (3) number of branches or wyes, and (4) amount of other open lines throughout the system. Explaining how to calculate these variables is beyond the scope of this manual. Consult an expert or purchase a good dust collection "how-to" book.

Power Connection

Electrocution or fire may occur if machine is ungrounded, incorrectly connected to power, or connected to an undersized circuit. Use a qualified electrician to ensure a safe power connection.

Once your machine is set up and assembled as previously described in this manual, it is ready to be connected to the power supply.

Note About 3-Phase Power: DO NOT use a static phase converter to create 3-phase power—it can quickly decrease the life of electrical components on this machine. If you must use a phase converter, only use a rotary phase converter and connect the manufactured leg to the correct power connection terminal, shown in the wiring diagrams on Pages 67–68.

To convert SB1096 for 440V operation:

1. DISCONNECT MACHINE FROM POWER!

2. Open electrical cabinet.

3. Remove wire labeled "1" at 220V terminal of

control power transformer (see Figure 27) and connect it to 440V terminal.

PREPARATION

Hardwiring to Power Supply

Hardwire setups require power supply lines to be enclosed inside of conduit, which is securely mounted and constructed in adherence to applicable electrical codes.

A hardwire setup for this machine must be equipped with a locking disconnect switch as a means to disconnect the power during adjustments or maintenance, which is a typical requirement for many lock-out/tag-out safety programs.

Figure 29 shows a simple diagram of a hardwire setup with a locking disconnect switch between the power supply and the machine.

Due to the complexity required for planning, bending, and installing the conduit necessary for a code-compliant hardwire setup, an electrician or other qualified person MUST perform this type of installation.

Connecting Power Supply Wires to Machine

Connecting power supply wires to machine without first disconnecting power supply may result in serious injury or death.

During next step, make sure incoming ground wire is connected to correct terminal to ensure machine will be properly grounded (see "Ground Terminal" in Figure 31). An ungrounded or improperly grounded machine can cause electrocution if live electrical wires make contact with frame or other parts touched by operator.

4. Connect ground wire to bottom of ground

terminal E, then connect incoming power wires to bottom "R", "S", and "T" terminals shown in Figure 31. If using a phase converter, connect wild wire to "T" terminal.

OPERATION

For Machines Mfd. Since 9/20

Sanding Workpieces

The sanding process is influenced by the feed rate, sanding depth, grit size and material type of sandpaper, platen position, and oscillation speed. We strongly recommend that you experiment with these variables, or research best practices for achieving your desired sanding results with the type of material you have. Also, to avoid unnecessary wear on belts, always make sure the workpiece has been surface planed with a jointer or planer before sanding.

Typically, no more than 0.020" (one full rotation of handwheel) of material should be removed during a single sanding pass. The maximum sanding depth can also be influenced by the thickness of the sanding belt, which can vary from 0.010" (fine sandpaper) to 0.060" (coarse sandpaper).

Attempts to remove too much material at one time can cause jamming, wood burning, rapid sandpaper wear or tearing, poor finish, short motor life, and belt slippage. The operator usually makes a pass, raises the table a little, and repeats until the entire surface is sanded to satisfaction. Before sanding, ensure you review Workpiece Inspection and put on the required safety glasses and respirator.

IMPORTANT: As you sand, observe the amp meter (see Figure 1 on Page 3). If the load meter indicates motor overload, slightly lower the table or reduce the feed rate.

Use the following tables to determine the approximate maximum depth-of-cut (DOC) for relative conveyor feed rates.

After selecting the appropriate feed rate chart, find the grit size you plan to use. Locate the correct DOC for that grit by selecting the correct wood hardness of the workpiece, and note the maximum DOC for the platen setting (up, even, or down).

Note: These numbers are approximate values only. They are provided with the intent of giving you a "ballpark" idea of what to expect for material removal rates from this machine. Many additional factors can influence the maximum depth-of-cut or removal rates that can be achieved with each pass (i.e. oscillation speed settings, depth-of-cut taken on previous pass, actual hardness of workpiece, etc.), so don’t be surprised if you experience slightly different results.

Note: It may take more than one pass to achieve the full sanding depth.

The overall sanding process consists of the operator starting sanding with the platen in the up position with a coarse grit sandpaper, such as #60, and then repeating this for subsequent grit sizes from #80–#100 until the workpiece is evenly smooth. The operator then sets the platen level with the drum and performs intermediate sanding passes using #100–#150 grit sandpaper. For the final sanding pass, the operator sets the platen in the down position and sands the workpiece using #180 grit or finer sandpaper. Refer to Adjusting Platen on Page 32 for more information about platen positions.

Workpiece Inspection

Some workpieces are not safe to cut or may require modification before they are safe to cut.

Before sanding, inspect all workpieces for the following:

• Material Type: This machine is intended

for sanding natural and man-made wood products. This machine is NOT designed to sand metal, glass, stone, tile, plastics, drywall, cement backer board, laminate products, etc.

Sanding improper materials increases risk of

respiratory harm to operator and bystanders due to especially ﬁne dust inherently created by all types of sanding operations—even if a dust collector is used. Additionally, life of machine and sanding belts will be greatly reduced (or immediately damaged) from sanding improper materials or from exposure to ﬁne dust created when doing so.

Position

* These numbers assume the platen is raised up during the sanding pass.

• Foreign Objects: Nails, staples, dirt, rocks

and other foreign objects are often embedded in wood. While sanding, these objects can become dislodged and tear sanding belt Always visually inspect your workpiece for these items. If they cannot be removed, DO NOT sand the workpiece.

• Wet or "Green" Stock: Sanding wood

with a moisture content over 20% causes unnecessary clogging and wear on the sanding belt, increases the risk of kickback, and yields poor results.

• Excessive Warping: Workpieces with

excessive cupping, bowing, or twisting can be dangerous to sand because they are unstable and unpredictable when being sanded. DO NOT use workpieces with these characteristics!

• Minor Warping: Workpieces with slight

cupping can be safely supported if the cupped side is facing the table. On the contrary, a workpiece supported on the bowed side will rock during sanding and could cause kickback injury.

Sanding Tips

• Avoid sanding a workpiece more than is necessary, since doing so will unnecessarily decrease belt life and cost you more money over time.

• Only sand with as slow of feed speeds as necessary to meet your sanding goals. In other words, avoid running the sander faster than is necessary. Increasing feed speeds beyond the required level can decrease the quality of the finished product and the lifespan of sanding belts.

• As a general rule, use the sanding drum for the initial heavy sanding pass, then use a combination of the platen and drum for the intermediate pass, and the platen alone for the final sanding passes.

• As a rule-of-thumb, sand with progressively higher grit numbers in increments of 50 or less.

• Replace sandpaper with a higher grit to achieve a ﬁner ﬁnish (refer to Installing/ Changing Sanding Belts on Page 31).

• When making multiple passes on the workpiece, avoid raising the conveyor table more than 0.015" (nearly one turn of the height handle or 3 touches of the Table Up key) per each pass.

• Reduce snipe when sanding more than one board of the same thickness by feeding them into the machine with the front end of the second board touching the back end of the ﬁrst board (aka "Butt Feeding").

• DO NOT sand boards smaller than 14" long, 2" wide and to the workpiece and the sander (see Figure 37).

2" Min.

Figure 37. Minimum dimensions for sanding.

• Extend the life of the sandpaper by regularly cleaning the sanding belt (refer to Cleaning Sanding Belt on Page 40).

• DO NOT edge-sand boards. This can cause boards to kickback, causing serious personal injury, or damage to the conveyor and sanding belt.

• Only use the load meter to keep the motor from overloading—that is its main purpose. Avoid using the load meter to monitor how much material is being removed, as this can lead to problems, including belts loading, burning, and poor quality sanding results.

• Make sure to adjust platen position accordingly when changing grit sizes.

• The faster the feed rate you use, the faster your sanding belts will wear out.

The Model SB1096 only accepts 37" wide by 60" long sanding belts. For additional sanding belt selections beyond those included with the machine, refer to Accessories on Page 35.

We recommend using aluminum-oxide sanding belts for best results. The grit you

choose will depend on the condition and species of wood, and the level of finish you wish to achieve.

When choosing sanding belts, use these grit numbers as a general guide:

Grit Type

60 or less ...................................................... Course

80–100........................................................ Medium

120–150............................................................ Fine

Adjusting Platen

This sander is equipped with an adjustable platen (see Figure 41) with a graphite pad that is designed to be used during finish sanding to create a polished-type finish and to prepare the workpiece for orbital sanding or a finish coat.

Figure 41. Platen removed from machine.

The platen position allows for 3 basic types of sanding: up, even, and down, which is adjusted with the platen adjustment lever (see Figure 42) to the desired position. The platen adjustment lock lever must be unlocked to adjust the platen.

Unlike the sanding drums, which typically produce short but deep scratch patterns, the platen produces long and shallow scratch patterns that create a smoother finish. Due to the cushioned-construction, the platen is less likely to leave belt-splice or chatter marks.

However, we do not recommend lowering the platen depth more than 2mm (about one complete turn of the lever) or over-using the platen by expecting it to remove marks beyond its ability to do so, since this can reduce the life of the sanding belt and platen, and result in premature streaking.

Tip: Given the short life-span of most graphite pads, keep replacement pads on hand.

Platen Up: The platen is raised above the drum (typically set at 1.5mm up), so only the sanding drum is making contact with the workpiece. This position is typically used for heavy sanding passes or dimensioning. The drum does all the work, but you will have a rough finish. Typically platens are used in this position with #100 or coarser grit.

OPERATION

Changing Feed Rate

The conveyor belt is variable-speed, which is controlled by the knob located on the front of the feed belt gearbox (see Figure 43).

Conveyor Speed Rate

............................... 15–49 FPM

Feed Rate

Adjustment

Knob

Platen Even: The platen is set level with the

drum. This position is used for intermediatefin ishing passes. The depth of cut should not exceed 0.010". This position typically uses #100-#150 grit.

Platen Down: The platen is set below the drum so it is the primary contact point while performing finish sanding.

The platen should be lowered to 0.2 to 0.5mm (maximum) below the sanding drums, but not more than 0.2mm per pass. You can lower the platen up to 2 mm below the drums for short inter vals, but streaking, burn marks, and premature graphite/platen wear can occur if this setting is abused or over-used.

It is not necessary to use the table height handwheel or Table Up key depth during the final sanding pass—the platen movement alone will take care of the depth of cut. Typically the final-sanding pass position uses #180 or finer grit.

Note: The platen scale is broken down in millimeter increments.

to adjust the sand ing

Figure 43. Feed rate adjustment knob location.

As a general rule, slower feed rates are more beneﬁcial than faster feed rates since they allow a belt to remove more material. We recommend you always start with the slowest feed rate and only increase the feed speed as needed to meet your sanding goals. Always test the feed rate using scrap wood similar to your workpiece.

Softwoods typically require a faster feed rate than hardwoods; however, there is no deﬁnitive rule to follow when determining the best feed rate to use for any type of wood.

Also, keep in mind that an increase in feed rate will increase the amperage load for a given sanding depth. This means you need to use shallower sanding depths at higher feed rates to avoid overloading the sanding motor.

To change feed rate:

1. Turn conveyor belt ON. Conveyor belt must

be running to adjust feed rate.

If workpiece has straight notches across it, graphite cloth and felt have worn out and need to be replaced.

Turn knob counterclockwise to increase feed

rate. Turn knob clockwise to decrease feed rate.

Note: Turn knob in 1⁄8" increments.

Reading Amp Meter

The amp meter (see Figure 44) is used to keep the motor from overloading during sanding operations. It should not be used as the main method for controlling sanding belt material removal rates—doing so can result in belt loading, burning, and even breaking—because there are many different variables that affect optimum removal rates and these will affect the amp load in different ways.

Amp load is directly affected by many factors such as feed rate, depth of cut, wood type, sandpaper grit, and workpiece width. If the amp load is in the red load range, the machine is overloaded and motor damage may soon occur. Adjust the table height accordingly to reduce the load, and use the amp load chart near the meter to keep the amp load in the green, SAFE range during operation.

Using EMERGENCY STOP Plate

The EMERGENCY STOP plate can help reduce the amount of damage to internal components during an emergency and can prevent operator injury. Pushing the EMERGENCY STOP plate (see Figure 45) causes the disc brake to stop the sanding belt motor, immediately stopping the sanding belt.

EMERGENCY STOP

Plate

Amp Meter

Figure 44. Location of amp meter.

As a general rule, always start with a small load and work your way up. DO NOT work the machine to its maximum load, or to where you can hear the motor lose RPM; instead, make multiple light passes or install a coarser grit sandpaper.

Keep amp draw within GREEN load range shown on the AMP LOAD CHART on the control panel. If you operate machine in RED load range, motor damage may occur and will not be covered under warranty.

Figure 45. Location of EMERGENCY STOP plate.

An operator should be careful when loading a workpiece not to trap fingers between workpiece and conveyor table, but in the event that it might happen, the EMERGENCY STOP plate can be pressed by operator while their hands are otherwise engaged.

Keep sanding drum V-belt correctly tensioned (refer to Page 51) to ensure proper functionality of EMERGENCY STOP plate. Otherwise, pulleys can slip when emergency stop brake is applied and not immediately stop the machine in the event of an emergency!.

Cleaning & Protecting

Cleaning the Model SB1096 is relatively easy. Vacuum excess wood chips and sawdust, and wipe off the remaining dust with a dry cloth. If any resin has built up, use a resin dissolving cleaner to remove it.

Lubrication

An essential part of lubrication is cleaning the components before lubricating them. This step is critical because dust and chips build up on lubricated components, which makes them hard to move. Simply adding more grease to built-up grime will not result in smooth moving parts. Clean the components in this section with an oil/ grease solvent cleaner or mineral spirits before applying lubrication.

All other bearings are sealed and permanently lubricated. Leave them alone until they need to be replaced.

Emptying Dust and Water Traps

Two collection traps on this sander need to be emptied regularly. DO NOT allow any of these traps to become full or you risk serious damage to the machine.

The air pressure regulator water trap (see Figure 56) is attached to the air pressure regulator and traps condensation in the incoming air supply.

With the system under air pressure, push the lower drain valve and empty the regulator water trap (see Figure 56). Also, replace the internal white moisture ﬁlters annually.

Cleaning Sanding Belt

To increase the working life of your sanding belts, clean them whenever they decrease in performance due to heavy loading of material. Use a Model D3003 PRO-STIK® Cleaning Pad as shown in Figure 58.

Adjusting Oscillation Timing & Speed

The oscillation adjustments have been performed at the factory and should require no further attention. However, we recommend verifying the settings.

When the oscillation is correctly adjusted, the sanding belt oscillates to the left and to the right at the same speed. If the sanding belt makes contact with a limit switch, as shown in Figure 59, the emergency braking system will activate and stop the sander immediately.

Limit Switch

Sanding Belt

— If belt tracks away from air fork and air

jet, colliding into limit switch, proceed to Setting Correct Airﬂow.

Setting Correct Airﬂow

An adequate stream of air through the air fork gap is essential for proper oscillation (see Figure

60). If airﬂow is weak through the gap, the belt

will track away from the controller and into the limit switch on the opposite end of the roller. The pivot action of the upper roller and the resulting oscillation of the belt are dependent upon adequate airﬂow through the air fork gap.

Servicing Platen

Always disconnect machine from power before performing maintenance or serious personal injury may result.

The platen graphite pad and felt pad should be inspected on a daily basis and replaced when they become worn or damaged.

Due to its function, it is very important for the graphite pad to be ﬂat, smooth, and free of grooves or low spots. It is also important that no dust or chips get trapped between the graphite pad and felt pad of the platen.

If surface defects are found, lightly hand-sand the platen to make the surface ﬂat again. If surface defects are more serious, the graphite pad may need to be replaced. If you notice a lot of streaking, this can also be a sign that the graphite pat or felt pad needs to be replaced.

Checking/Adjusting Table Parallelism

Table parallelism has been adjusted at the factory and should not require adjustment when the machine is new.

We only recommend adjusting table parallelism if absolutely necessary due to factors that may cause the factory settings to change. Adjusting the table parallelism can take a fair amount of patience.

IMPORTANT: DO NOT adjust the table unless you are having trouble sanding your workpiece to a uniform thickness and have eliminated all other possible causes. For instance, a sanding or conveyor belt that is unevenly worn should be replaced before adjusting table parallelism.

Checking Table Parallelism

1. DISCONNECT MACHINE FROM POWER!

2. Use vacuum cleaner and shop rag to clean

table and frame at each corner so sawdust will not interfere with measurements during following steps.

Adjust table elevation until it is

approximately 6" below sanding belt.

Take precise measurement of wood

block (approximately 4" long) and record measurement.

Place wood block on edge of table at rear left

corner, then raise table until wood block just touches upper frame (see Figure 79). Do not allow table to squeeze or compress wood block.

Note: Make sure wood block does not touch

conveyor belt.

— If measurement of any corner from Step

6 is not exactly the same as length of

wood block measured in Step 4, table is not parallel to frame. DO NOT remove wood block. Proceed to Adjusting Table Parallelism.

Adjusting Table Parallelism

1. DISCONNECT MACHINE FROM POWER!

2. With wood block still positioned at rear left

corner of conveyor table, locate elevation leadscrew flange (see Figure 80) at corner that needs to be adjusted.

Loosen table mounting bolts on flange (see

Figure 80). Rotate flange a small amount to adjust that corner of table until it is within

0.003" of measurement of wood block.

Note: Each leadscrew ﬂange can be adjusted

up to 0.015" between right and left sides. Rotating left will lower table and rotating right will raise table.

Wood Block

Figure 79. Example of wood block placed for checking

table parallelism.

Take precise measurements at each of

the three remaining corners, between the conveyor table and the upper frame.

— If measurements from all corners in

Step 6 are exactly the same as length of wood block measured in Step 4, table is parallel to frame and no adjustment is necessary. Remove wood block.
