Safety Instructions For Oscillating Edge Belt/ Spindle Sander

Safety is a combination of common sense, staying alert and knowing how your oscillating edge belt/spindle sander works. Read this manual to understand this sander.

Safety Signal Words

DANGER: means if the safety infor-

mation is not followed someone will be seriously injured or killed.

Before Using The Sander

WARNING: Some dust created by power sanding, saw in g, grin ding, drilling, and other co nstruction activities contains chemicals k nown (to the State of California) to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:

• Lead from lead-based paints,

• Crystalline silica from bricks and c ement and other masonry products, and

• Arsenic and chromium from chemically-treated lumber.

Your risk from these exposures varies, depending on h ow often you do this type of work. To reduce your exposure to these chemicals: work in a well ventilated area, and w ork with approved safety equipment, such as those dust masks that are special ly designed to filter out microscopic particles.

WARNING: means if the safety infor-

mation is not followed someone

could be seriously injured or killed. CAUTION: means if the safety infor-

mation is not followed someone ma y be injured.

WARNING: To reduce the risk of mistakes that could cause serious, permanent injury, do not plug the sander in until the following steps are completed.

• A s sem bly. (See pages 12-19)

• Learn the use and function of the ON-OFF switch. (See page 21)

• Review and understanding of all safety instructions and operating procedures in this manual.

• Review of the maintenance methods for this sander. (See page 29)

Page 4

Safety Instructions for Oscillating Edge Belt/ Spindle Sander (continued)

Read the following WARNING labels found on the sander:

When Installing O r Moving The Sander

Avoid dange rou s envi ronment.

Use the sander in a dry, indoor place protected from rain. Keep work area well lighted.

To reduce the risk of burns or other fire damage, never use the sander near flammable liquids, vapors or gasses.

To reduce the risk of injury or death from electrical shock:

• Ground the sander. This sander has an approved 3-conductor cord and a 3-prong grounding type plug. Use only 3-wire, grounded outlets rated 120 volts, 15 amperes (amps). The green conductor in the cord is the grounding wire. To reduce the risk of electrocution, Never connect the green wire to a live terminal.

• Make sure your fingers do not touch the plug’s metal prongs when plugging or unplugging the sander.

• N e ve r use this or any power sander for wet sanding. Doing so could

cause electrocution, serious injury or worse.

To red uce the risk of injury from unexpected sander moveme nt:

• Always unplug the sander before moving it.

• Put the sander on a firm level surface where there is plenty of room for handling and properly supporting the workpiece.

• Attach rubber feet.

• Support the sander so it does not rock.

• Bolt the sander to its work surface. Use the fasteners and method shown in “Assembly.” (See page

16.)

• Never stand on tool. Serious injury could occur if the tool tips. Do not store anything above or near the tool where anyone might stand on the tool to reach it.

Page 5

Before Each Use

Inspect your sander. Check for:

• alignment of moving parts,

• binding of moving parts,

• broken or damaged parts,

• w o rk parts that cause a gap larger than 1/16" between work support and sanding surface,

• sanding belt narrower than 4 inches. Narrower belts uncover parts that could trap your fingers,

• w o rn or damaged electric cords,

• stable mounting, and

• any other conditions that may affect the way the sander works.

• Remove adjusting keys and wrenches. Form a habit of checking for and removing keys and adjusting wrenches from table top before turning sander on.

If any part is missing, bent, or broken in any way, or any electrical parts don’t work properly, turn the sander off and unplug the sander. Replace damaged, missing, or failed parts before using the sander again.

Disconnect the sander to reduce the risk of injury from accidental starting. Turn switch off, unplug sander and remove the switch key before changing the setup or sanding drum.

Maintain tools with care. Keep the sander clean for maximum and safest performance.

To red uce the risk of injury from jams, slips or thrown pieces:

• Use only recommended accessories.

• Use the correct spacer ring insert. The opening between the sanding sleeve and insert must be 5/32 of an inch or less. (See page 15)

• All sanding drums, washers and knobs are tight. No parts should have excessive play prior to operating unit.

• Keep work area cl ean . Cluttered work surfaces invite accidents. Floor must be clean and dry for stable footing.

Plan Ahead To Protect Your Eyes, Hands, Face and Ears

Dress for Safety

• Any power sander can throw foreign objects into the eyes. This can result in permanent eye damage. Always wear safety goggles, not glasses complying with AN S I Z87.1 (or in Canada CSA Z94.3-99) shown on package. Everyday eyeglasses have only impact resistant lenses. They are not safety glasses. Safety goggles are available at many local retail stores. Glasses or goggles not in compliance with ANSI or CSA could seriously hurt you when they break.

• Sanding operation s are usually dusty. Wear a dust mask along with the safety goggles.

• Wear nonslip footwear.

• Tie back long hair.

• Roll long sleeves above the elbow.

• Noise levels vary widely. To reduce the risk of possible hearing damage, wear ear plugs or muffs when using sander for hours at a time.

Page 6

Safety Instructions for Oscillating Edge Belt/ Spindle Sander (continued)

• Do not wear loose clothing, gloves, neckties or jewelry (rings, wrist watches). They can get caught and draw you into moving parts.

Know your sander. Read and understand the owner’s manual and labels affixed to the tool. Learn its application and limitations as well as the specific potential hazards.

Plan your work. Think through how you will hold and maneuver the workpiece against the sanding drum or belt.

Use the right tool. Don’t force tool or attachment to do a job it was not designed to do.

To reduce the risk of injury from accidental contact with moving parts:

• D o not layout, assem ble, or setup work on the sander while any parts are moving.

• Reduce the risk of accidental starting. Make sure swit ch is “O FF” before plugging sander into a power outlet.

Inspect your workpiece. Make sure there are no nails or foreign objects in the part of the workpiece to be sanded.

Plan the way you will hold the workpiece from start to finish. Reduce the risk of awkward operations and hand positions where a sudden slip could cause finger or hand to move into a sanding surface.

Don’t overreach. Maintain balance and footing.

Keep face and body to one side. Stay out of l ine of a possible throwback.

Plan your work to reduce the risk

of THROWBACKS - when the workpiece catches the sanding drum and is torn from your hands:

• Make sure there is no debris between the workpiece and its supports.

• When sandi ng irregularly shaped workpieces, plan your work support so it will not slip and be pulled from your hands.

• Use extra caution with large, very small or awkward workpieces.

• Never use this tool to finish pieces too small to hold by hand.

• Use extra supports (tables, saw horses, blocks, etc.) for any workpieces large enough to tip when not secured to the work surface.

• Never us e another person as a substitute for a table extension, or as additional support for a workpiece that is longer or wider that the basic sander table, or to help feed, support or pull the workpiece.

• Sand only one workpiece at a time.

• Clear everything except the workpiece and related support devices off the table before turning the sander on.

• Always feed workpiece from right to left against the direction the sanding sleeve or belt is rotating.

• Do not use drums, sanding sleeves or sanding belts which show visual signs of wear such as grooves, tears o r rips.

WARNING: Don’t let familiarity (gained from frequent use of your sander) cause a careless mistake. A careless fraction of a second is enough to cause a severe injury.

Page 7

When Sander is Running

Before starting your work, watch the sander while it runs. If it makes an unfamiliar noise or vibrates excessively , Stop Immediately. Turn the sander off. Unplug the sander. Do not restart until identifying and correcting the problem.

Never leave tool running unattended.

Before using the sander, make sure the sanding belt turns clockwise, when viewed from above.

Keep children away. Keep all visi-

tors a safe distance from the sander and workpiece.

Don’t force tool. It will perform better and safer at its designed rate. Press workpiece against the sanding sleeve hard enough to begin sanding without bogging down or binding spindle or belt.

Before freeing any jammed material:

• Turn switch “OFF”.

• Unplug the sander.

• Wait for all moving parts to stop.

Before Leaving The Sander

Turn switch off. Don’t leave tool until

the unit comes to a complete stop. Make workshop child-p roof.

Remove the yellow switch key. Store

it away from children and others not qualified to use the tool. Disconnect master switches. Lock the shop.

Precautions To Take When Sanding Metals

When sanding metals, sparks or hot fragments could cause a fire. To reduce the risk of this:

1. Disconnect any dust collecting hose from the sander.

2. Remove all traces of wood dust from inside the unit before sanding metals.

3. Remove all traces of metal dust from inside the unit before sanding wood again.

Precautions To Take When Sanding Paint

Sanding of lead based paint is not recommended. It is difficult to control

the contaminated dust that could cause lead poisoning.

It is also difficult to identify whether or not a paint contains lead. Therefore, we recommend the following precautions when sanding all paints:

1. Protect your lungs. Wear a dust mask or respirator at all times. Wear only dust masks t h at a re suit able for working in lead paint sanding environments. Ordinary painting masks do not offer this protection.

2. Do not allow children or pregnant women to enter the work area until paint sanding job is complete and work area is clean.

3. To prevent ingesting contaminated paint particles: Do not eat, drink, or smoke in a work area where paint is being sanded. After sanding paint, wash and clean up before eating, drinking or smoking. Do not leave food, drinks, or tobacco products in the work area where dust can settle on them.

Page 8

Precautions To Take When Sanding Paint (continued)

4. Protect the environment when sanding paint. Use a dust collection system if possible. Seal the work area with plastic if necessary. Do not track paint dust outside the work area.

5. Thoroughly clean the work area upon completion of paint sanding

project. If project lasts for an extended period of time, clean work area often. Items such as sanding dust, vacuum filter bags, plastic drop cloths, etc. should be placed in a sealed container and disposed of properly. Clean all items exposed to sanding dust.

110-120 Volt, 60 Hz. Tool Information

NOTE: The plug supplied on your tool

may not fit into t he outl et you ar e planni ng to use. Your local electrical code may require slightl y different power cord plug connections. If these diff erences exist refer to and make the proper adjustments per your local code before your tool is plugged in and turned on.

In the event of a malfuncti on or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This tool is equipped with an electric cord having an equipment groundi ng conductor and a grounding plug, as shown. The plug must be plugged into a matching outlet that is properly installed and grounded in accordance with all local codes and ordinances.

Do not modify the plug provided. If it will not fit the outlet, have the proper outlet installed by a qualified electrician.

A temporary adapter may be used to connect this p lug t o a 2-p ole outl et, a s shown, if a properly grounded out let is not available. This temporary adapter should be used only unti l a properly grounded outlet can be installed by a qualified electrician. The green colored rigid ear, lug and the like, extension from the adapter must be connected to a permanent ground such as a properly grounded outl et box.

Improper connecti on of the equipment grounding conductor could result in a risk of electric shock. The conductor with i nsulation having an outer surface that is green with or without yell ow str ipes is the equipment grounding conductor. If repair or replacement of the electric cord or plug is necessary, do not connect the equipment-grounding conductor to a live terminal.

If the grounding instructions are not completely unde rstood, or if you are in doubt as to whether the tool is properly grounded, check with a qualified electrician or service personnel.

WARNI NG: If not properly grounded, this tool can cause an electrical shock, particularly when used in damp locations, in proximity to plu m bi ng, or out of doors. If an electrical shock occurs there is the potential of a secondary hazard, such as your hands contacting the sanding belt/spindle.

Motor Specifications and Electrical Requirements (continued)

Motor Safety Protection

IMPORTANT: To reduce the risk of motor

damage, the motor should be blown out or vacuumed frequently to keep sawdust from interferi ng with normal motor ventilation.

1. Connect this tool to a power source with the appropriate voltage for your model and a 15 -amp bran ch cir cuit wi th a 15-amp fuse or circ uit breaker. Using the wrong size fuse can damage the motor.

2. If the motor won't start, turn off the power switch immediately and unplug the tool. Check the spindle to make sure it turns freel y. If the spindle is free, try to start the motor again. If the motor still does not start, refer to the "Troubleshooting” char t.

3. If the motor suddenly stalls while sanding, turn off the power switch, unplug the tool, and remove the workpiece from the belt/drum. The motor may now be restart ed and the sanding finished.

4. Fuses may "blow" or ci rcuit breakers may trip frequen tl y if: a. Motor Is Overloaded-Overloading

can occur if you sand t oo rapi dly or make too many st art/stops in a short time.

b. Line voltages should not be more

than 10% above or below the nameplate voltage. For heavy loads, however, the voltage at motor terminals must equal the voltage specified for your model.

5. Most motor troubles may be traced to loose or incorrect connections, overload, low voltage (such as sm all size wire in the supply circui t) or to overly long supply circuit wire. Always check the connections, the load and supply circuit whenever motor doesn't work well. Check wire sizes and extension cord length with the Wire Size Chart.

Wire Size s

NOTE: Make sure the proper extension

cord is used and is in good condition. The use of any extensi on cord will cause

loss of power. To keep this to a minimum and to prevent over heating and motor burn-out, use the table shown to determine the minimum wire size (A. W.G.) extension cord.

Use only 3-wire extension cords with 3prong grounding type plugs and 3-pole receptacles.

Safety Instructions for Oscillating Edge Belt/Spindle Sander

Before Using The Sander

WARNING: To reduce the risk of mistakes that could cause serious, permanent inju ry, do not plug the san der in until the following steps are completed.

• A s sem bly. (See pages 12-19)

When Installing O r Moving The Sander

Avoid dange rou s envi ronment.

Use the sander in a dry, indoor place protected from rain. Keep work area well lighted.

To reduce the risk of burns or other fire damage, never use the sander near flammable liquids, vapors or gasses.

To reduce the risk of injury or death from electrical shock:

• Ground the sander. This sander has

an approved 3-conductor cord and a 3-prong grounding type plug. Use only 3-wire, grounded outlets rated 120 volts, 15 amperes (amps). The green conductor in the cord is the grounding wire. To reduce the risk of electrocution, Never connect the green wire to a live terminal.

• Make sure your fingers do not touch

the plug’s metal prongs when plugging or unplugging the sander.

• N e ve r use this or any power sander

• Learn the use and function of the ON-OFF switch. (See page 21)

• Review and understanding of all safety instructions and operating procedures in this manual.

• Review of the maintenance methods for this sander. (See page 29)

for wet sanding. Doing so could cause electrocution, serious injury or worse.

To red uce the risk of injury from unexpected sander moveme nt:

• Always unplug the sander before moving it.

• Put the sander on a firm level surface where there is plenty of room for handling and properly supporting the workpiece.

• Attach rubber feet.

• Support the sander so it does not rock.

• Bolt the sander to its work surface. Use the fasteners and method shown in “Assembly.” (page 16)

• Never stand on tool. Serious injury could occur if the tool tips. Do not store anything above or near the tool where anyone might stand on the tool to reach them.

Before Each Use

Inspect your sander. Check for:

• alignment of moving parts,

• binding of moving parts,

• broken or damaged parts,

• w o rk parts that cause a gap larger than 1/16" between work support and sanding surface,

• sanding belt narrower than 4 inches. Narrower belts uncover parts that

could trap your fingers,

• worn or damaged electric cords,

• stable mounting, and

• any other conditions that may affect the way the sander works.

• Remov e adjusting keys and wrenches. Form a habit of checking for and removing keys and adjusting wrenches from table top before turning sander on.

Page 23

Disconnect the sander to reduce the risk of injury from accidental starting. Turn switch off, unplug sander and remove the switch key before changing the setup or sanding drum.

Maintain tools with care. Keep the sander clean for maximum and safest performance.

To reduce the risk of injury from

• Use only recom mend ed acce ssories.

• Use the correct spacer ring insert. The opening between the

sanding sleeve and insert must be 5/32 of an inch or less. (See page

15)

• All sanding drums, washers and knobs are tight. No parts should have excessive play prior to operating unit.

• Keep work area cl ean . Cluttered work surfaces invite accidents. Floor must be clean and dry for stable footing.

jams, slips or thrown piec es:

Plan Ahead To Protect Your Eyes, Hands, Face and Ears

Dress for Safety

• For dusty operations, wear a dust mask along with safety goggles.

• W ear nonslip footwear.

• Tie back long hair.

• R o ll long sleeves above the elbow.

• Noise levels vary widely. To reduce the risk of possible hearing damage, wear ear plugs or muffs when using sander for hours at a time.

• S anding operations are usually dusty. Wear a dust mask along with the safety goggles.

• Do not wear loose clothing, gloves, necktie s or je w elr y ( rin gs , w ris t watches). They can get caught and draw you into moving parts.

Know your sander. Read and understand the owner’s manual and labels affixed to the tool. Learn its application and limitations as well as the specific potential hazards.

Plan your work. Think through how you will hold and maneuver the workpiece against the sanding drum or belt.

Use the right tool. Don’t force tool or attachment to do a job it was not designed to do.

To red uce the risk of injury from accidental contact with moving parts:

• Do not layout, assemble, or setup work on the sander while any parts are moving.

• Reduce the risk of accidental starting. Make sure swi tch i s “OFF” before plugging sander into a power outlet.

Page 24

Safety Instructions for Oscillating Edge Belt/ Spindle Sander (continued)

Inspect your workpiece ma ke sure

there are no nails or foreign objects in the part of the workpiece to be sanded.

Plan the way you will hold the workpiece from start to finish.

Reduce the risk of awkward operations and hand positions where a sudden slip could cause finger or hand to move into a sanding surface.

Don’t overreach. Maintain balance and footing.

Keep face and body to one side. Stay out of line with a possible throwback.

Plan your work to reduce the risk of THROWBACKS - when the workpiece catches the sanding drum and is torn from your hands:

• Make sure there’s no debris between the workpiece and its supports.

• When sanding irregularly shaped workpieces, plan your work support so it will not slip and be pulled from your hands.

• U se ext ra caution with large, very small or awkward workpieces.

• N e ve r use this tool to finish pieces

too small to hold by hand.

• Use extra supports (tables, saw horses, blocks, etc.) for any workpieces large enough to tip when not secured to the work surface.

• Sand only one workpiece at a time.

• Clear everything except the workpiece and related support devices off the table before turning the sander on.

• Always feed workpiece from left to right against the direction the drum sleeve is rotating.

• Do not use drums, sanding sleeves or belts which show visual signs of wear such as grooves, tears or rips.

WARNI NG: Don’t let familiarity (gained from frequent use of your sander) cause a careless mistake. A careless fraction of a second is enough to cause a severe injury.

When Sander is Running

Before starting your work, watch the sander while it runs. If it makes an unfamiliar noise or vibrates excessively, Stop Immediately. Turn the sander off. Unplug the sander. Do not restart until identifying and correcting the problem.

Never leave tool running unattended.

Before using the sander, make sure the sanding belt turns clockwise,

when viewed from above. Keep children away. Keep all visi-

tors a safe distance from the sander and workpiece.

Don’t force tool. It will perform better and safer at its designed rate. Press workpiece against the sanding sleeve or belt hard enough to begin sanding without bogging down or binding spindle.

Page 25

Before freeing any jammed material:

• Turn switch “OFF”.

• U n plug th e sander.

• Wait for all moving parts to stop.

Before Leaving The Sander

T urn switch off. Don’t leave tool until

the unit comes to a complete stop. Make workshop child-proof.

Remove th e yellow swi t ch key. Store it away from children and others not qualified to use the tool. Disconnect master switches. Lock the shop.

Precautions To Take When Sanding Metals

When sanding metals, sparks or hot fragments could cause a fire. To reduce the risk of this:

1. Disconnect any dust collecting hose from the sander.

2.Re m ove al l t r aces of w ood dust from inside the unit before sanding metals.

3.Remove all traces of metal dust from inside the unit before sanding wood again.

Precautions To Take When Sanding Paint

Sanding of lead based pai nt i s not recommended. It is difficult to co n tr o l the

contaminated dust that could cause lead poisoning.

It is also difficult to identify whether or not a paint contains lead. Theref ore, we recommend the following precautions when sanding all paints:

1. Protect your lungs. Wear a dust mask or respirator at all times. Wear only dust masks that are suit able for worki ng in lead paint sanding environments. Ordinary painting masks do not offer this protection.

2.Do not allow children or preg nant

women to enter the work area until paint sanding job is complete and work area is clean.

3.To prevent ingesting contaminated

paint particles: Do not eat, drink, or

smoke in a work area where paint is being sanded. After sanding paint, wash and cl ean up before eating, drinking or smoking. Do not leave food, drinks, or tobacco products in the work area where dust can settle on them.

4.Protect the environment when sanding paint. Use a dust collection system if possible. Seal the wor k area with plastic if necessary. Do not track paint dust outside the work area.

5.Thoroughly clean the work area upon completion of paint sanding proj ect. If project lasts for an extended period of time, clean work area often. Items such as sanding dust, vacuum filter bags, plastic drop cloths, etc. should be placed in a sealed container and disposed of properly. Clean all items exposed to sanding dust.

Basic Sanding Operati on

Sandpaper Selection

Selecting the correct size diameter, cor rect size grit, and correct type sandpaper is an extremely important step in achieving a high quality sanded fini sh. Aluminum oxide, silicon carbide, and other synthe ti c abrasives are best for power sanding. Natural abrasives, such as flint and garnet, are too soft for econom ical use in power sanding.

In general, coarse grit will remove the most material and finer grit will produce the best fi nish in all sanding operations. The condition of the surface to be sanded will determine which grit will do the job. If the surface is rough, start with a coarse grit and sand until th e surf ace is uniform. Medium grit may then be used to r em ove scratches lef t by the coarser grit and finer grit used for finishing of the surface. Always continue sand ing with each grit until surface is uniform.

NOTE: Do Not use sander without sand paper. Doing so will damage the r ubber drum.

Select and inst all the desired sanding sleeve for your particular application. Sanding sleeves from 1/2" to 2" can be used with this sander. Choose one that is close in size to the workpiece you are sanding. Also install the appropriate spacer ring insert (page 15).

WARNI NG: Fail ure to u se the correct size spacer ring insert with its matching sanding sleeve coul d result in fingers being pinched or the workpiece bein g pulled down between the spacer ring insert and sanding sleeve.

NOTE: The correct size sanding belt is 4"

x 24". These bel ts ar e avail able i n coarse, medium and fine gri ts.

1/2" 3/4" 1" 1-1/2" 2"

Surface Sanding on the Sanding Belt

WARNING: To reduce the risk of injury from slips, jams or thrown pieces, adjust the backstop to clear the sanding surface by no more than 1/16 of an inch. When checking clearance between the sanding belt and backstop, press the sanding belt flat against the metal bed beneath i t.

Hold the workpiece firm ly with bot h hands, keeping fingers away from the sanding belt.

Keep the end butted agai nst the backstop and move the work evenly across the sanding belt. Use caution when sanding very thin pieces.

For sanding long pieces the bac kstop can be rotated out of the way.

Apply only enough press ure to allow the sanding belt to remove material.

End Sanding on the Sanding Belt

Move the work evenly across the sanding belt. For accuracy, use a miter gauge accessory (not included).

Sanding Curved Edges

Inside curves are best sanded with the sander assembl ed in the spindle mode. However, inside curves larger than 1-1/2" may be sanded on the dri ve drum wh en i n the belt sander mode.

Although it is possi ble to lightly sand on the idler drum end of the belt sanding assembly, it is not recommended. The idler drum is an integral part of the belt tracking mechanism. It is spring loaded to maintain proper tension. Use of the idler drum to sand curves may cau se belt to track improper ly.

Basic Sanding O peration (continued)

Feed Direction

WARNING: To prevent thrown workpiece, feed workpiece against sanding sleeve from left to right as shown.

The sanding sleeve rotates clockwise. Feed the workpiece agai nst the sanding sleeve from left fed from left to right, the rotation of the sanding sleeve sands against the workpiece. If fed in the opposite direction, the rotation forces of the spinning sandi ng sleeve will tend to throw or bounce the workpiece away from the sanding sleeve. This could cause loss o f cont rol of workpiece or injury.

Dust Collection Capability

A standard 2-1/2" dust exhaust port has been provided to make dustless sanding possible. It is on the rear of your sander as shown. The pickup adapter end of a vacuum hose fits inside the dust exhaust port with a wedge fit.

Even with a dust collection system, it is necessary to peri odically clean sanding dust from the recess in the t ab le. Sa wdust buildup in the table recess may prevent the belt or spindle from making a complete oscillat ion, which may cause premature wear .

to right as shown. When

Transporting Sander

When using your sander in a por table application, i t is acceptable to lift and carry sander by the table top by the carry handles. Be careful when tr ansporting to reduce the risk of dislodging accessories, spacer ring inserts, wrench, and upper spindle washers from thei r respective storage areas.
