SAFETY
For Machines Mfd. Since 11/23

Additional Oscillating Edge Sander Safety

Serious injury or death can occur if fi ngers, clothing, jewelry, or hair get entangled in moving components. Impact injuries can occur from kickback if workpiece is improperly fed into moving sanding belt. Serious pinch injuries can occur from touching in-running nip point between table and sanding surface. Long-term respiratory damage can occur from using sander without proper use of a respirator. To reduce the risk of these hazards, operator and bystanders MUST completely heed the hazards and warnings below.
Avoiding Entanglement. Becoming entangled
in moving parts of this machine can cause pinching and crushing injuries. To avoid these hazards, DO NOT wear loose clothing, gloves, or jewelry, and tie back long hair. Keep all guards in place and secure.
In-Running Nip Points. The gap between moving
sanding belt and fixed table/support creates a pinch point for fingers or workpieces; the larger this gap is, the greater risk of fingers or workpieces getting caught in it. Minimize this risk by adjusting table no more than belt.
Sanding Belt Direction. Feeding workpiece
incorrectly can cause it to be thrown from machine, striking operator or bystanders, or causing your hands to slip into the moving sanding belt. To reduce these risks, only sand against direction of sanding belt travel, ensure workpiece is properly supported, and avoid introducing sharp edges into moving sanding belt on leading side of workpiece.
Workpiece Support & Hand Placement. Rotating
sanding belt can remove a large amount of skin quickly, and kickback can occur with violent force if workpiece is not properly supported during operation. Always sand with workpiece firmly against table or another support device. Never touch moving sanding belt on purpose.
Workpiece Integrity. Only sand solid workpieces
that can withstand power sanding forces. Make sure shape of workpiece is properly supported on table; avoid sanding workpieces without flat bottom surfaces unless some type of jig is used to maintain support and

Small Workpieces.
to control and require close support near sanding surface. Always use a jig or other holding device when sanding small workpieces, and keep hands and fingers at least 2" away from sanding surface.
Workpiece Inspection. Nails, staples, knots, or
other imperfections in workpiece can be dislodged and thrown from sander at high rate of speed into operator or bystanders, or cause damage to sanding belt or sander. Never try to sand stock that has embedded foreign objects or questionable imperfections.
Sanding Belt Condition. Worn or damaged
sanding belt not only produces poor sanding results, but could fly apart, aggressively grab workpiece, and throw debris at the operator. Always inspect sanding belt before operation and replace if worn or damaged.
Sanding Dust & Dust Collection. Sanding creates
large amounts of dust and flying particles that can lead to eye injury or respiratory illness. Reduce risk by wearing approved eye and respiratory protection when using sander. Never operate without adequate dust-collection system in place and running. Proper dust collection reduces dust in work area, decreasing risk of long-term
for using a respirator.

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 in accordance with 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.
This machine is prewired to operate on a power supply circuit that has a verified ground and meets the following requirements:
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.)

Lifting & Moving

This machine and its parts are heavy! Serious personal injury may occur if safe moving methods are not used. To reduce the risk of a lifting or dropping injury, ask others for help and use power equipment.
Using only one eye bolt or a different lifting method could unbalance and tip machine, which could result in serious injury or machine damage. To reduce risk of this injury, be sure to use BOTH eye bolts to lift machine.
Do not attempt to lift or move this machine without using the proper lifting equipment (such as a forklift or crane). Each piece of lifting equipment must be rated for at least 1050 lbs. to support the dynamic loads that may be applied while lifting.
Figure 9. Loose inventory.
If you cannot find an item on this list, carefully check around/inside the machine and packaging materials. Often, these items get lost in packaging materials while unpacking or they are pre-installed at the factory.
-14-
Move the pallet to a suitable location (see Location on Page 15). Remove any loose small items from the machine, remove the shipping brackets securing the machine to the pallet, then attach lifting straps or chains to the eye bolts shown in Figure 10. Lift the machine just enough so the pallet can be removed, then lower the machine to place it in your desired location.

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 respirator and capturing the dust with a dust-collection system.
Recommended CFM at Dust Port: 400 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.

Stock Inspection & Requirements

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

Sanding Tips

• Avoid sanding a workpiece more than is necessary, since doing so will unnecessarily decrease sanding belt life and cost you more money over time.
• Extend the life of sanding belts by regularly using an abrasive surface cleaner.
• As a rule-of-thumb, sand with progressively higher grit numbers in increments of 50 or less.
• Replace sanding belt with a higher grit to achieve a finer finish (refer to Installing/ Changing Sanding Belts on Page 23).
• Hold the workpiece securely with both hands. Use the tables/miter stop/back stop whenever possible to support workpieces. Do not force the workpiece against the sanding belt.
• When sanding workpieces with a bow or crown, place the high point up on the table to prevent the workpiece from rocking, then take very light passes.
• Use the full width of the sanding belt by adjusting the table height or workpiece position so sanding is not always done in just one area.
• Make sure belt guard is closed and secured during operation.
• Sanding belts clog and wear. Change sanding belt whenever you notice a difference in sanding quality/performance.
-22-
Moving sanding belt can cause serious personal injury if it comes in contact with fingers, hands, or other body parts. Always support workpiece against table or miter stop when sanding. Use extreme care to provide safe distance between sanding belt and any body part.

OPERATION

Choosing Sanding Belts

The Model SB1127 uses a 9" x 1381/2" sanding belt.
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.
Grit Class Usage
36 Extra
Coarse
60 Coarse Thickness sanding and
80–100 Medium Removing marks and
120–180 Fine Finish sanding.
The general rule of thumb is to sand a workpiece with progressively higher grit numbers—in increments of 50 or less. Avoid skipping grits; the larger the grit increase at one time, the harder it will be to remove the scratches from the previous grit.

Checking/Adjusting Sanding Belt Tracking

The purpose of sanding belt tracking is to make sure the sanding belt stays centered on the rollers and platen during sanding operations. The sanding belt tracking needs to be checked any time you change or replace the sanding belt.
If the sanding belt tracking is not adjusted properly, the sanding belt can be damaged and present a serious safety hazard if it moves off center of the rollers and throws material when it contacts the belt guard and other components.
OPERATION
Note: When sanding belt oscillation is turned
ON, sanding belt will oscillate up and down on rollers, but will ultimately stay centered on rollers so it does not wander off of rollers. Do not confuse sanding belt oscillation with poor sanding belt tracking.

Any support fixture close to the platen that is more than an in-running nip point that could pull fingers or workpieces into the open space.
A shop-made auxiliary fence will allow you to use the installed miter stop for operations where the platen has been tilted, instead of removing it and installing some other jig or fixture. This fence should be cut to the same angle as the platen tilt in order to minimize the risk of pinch points for fingers or workpieces.

Maintenance Schedule

Always disconnect machine from power before performing maintenance or serious personal injury may result.
For optimum performance from your machine, follow this maintenance schedule and refer to any specific instructions given in this section.
Ongoing
To minimize your risk of injury and maintain proper machine operation, shut down the machine immediately if you ever observe any of the items below, and fix the problem before continuing operations:
• Loose mounting bolts.
• Damaged or dirty sanding belt.
• Worn or damaged wires.
• Dirty or unprotected cast-iron surfaces.
• Any other unsafe condition.
Weekly Maintenance
• Clean/vacuum dust buildup from inside cabinet and belt guard and off of motor.

Cleaning & Protecting

Cleaning the Model SB1127 is relatively easy. Vacuum excess 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.
Protect the unpainted cast iron table by wiping them clean after every use—this ensures moisture from wood dust does not remain on bare metal surfaces. Keep the tables rust-free with regular applications of quality metal protectants.

Cleaning Sanding Belts

As sanding belts are used, they will quickly become "loaded" with sawdust. If not removed, this sawdust will harden on the abrasive surface, rendering the sanding belt useless. Routinely clean the sanding belts with a rubber gum abrasive surface cleaner .
Always discard worn sanding belts. As abrasive belts begin to wear, grit will begin to fall off, causing deep gouges in the workpiece. Glue used to hold the grit to the sanding belt will rub off onto the workpiece, causing burns and interference with final finishing.
Monthly Maintenance
• Lubricate table adjustment components (Page 34).
Lubricate platen tilt components
• (Page 35).
Contrary to some beliefs, worn abrasive belts are not equivalent to next finer grit abrasive. Discard worn sanding belts and avoid temptation to use them beyond their usable life.

Lubrication

An essential part of lubrication is cleaning the components before lubricating them. This step is critical because dust builds 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 mentioned in this section with an oil/grease solvent cleaner or mineral spirits before applying lubrication.

Replacing Oscillation Motor Brushes

The oscillation motor uses two carbon brushes to transmit electrical current inside the motor. These brushes are considered regular "wear items" or "consumables" that will need to be replaced during the life of the motor. The frequency of required replacement is often related to how much the motor is used and how hard it is pushed.
Replace the carbon brushes at the same time when the motor no longer reaches full power, or when the brushes measure less than brushes are
If your machine is used frequently, we recommend keeping an extra set of these replacement brushes on-hand to avoid any downtime.
