BEFORE USING YOUR MACHINE

To avoid serious injury and damage to the tool, read and follow all of the Safety and Operating Instructions before operating the machine.

1. Some dust created by using power tools contains chemicals known 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, cement, and other
• masonry products.

• Arsenic and chromium from chemically treated lumber. Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a well ventilated area and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscopic particles.

• READ the entire Owner's Manual. LEARN how to use the tool for its intended applications.

• GROUND ALL TOOLS. If the tool is supplied with a 3-prong plug, it must be plugged into a 3-contact electrical receptacle. The 3rd prong is used to ground the tool and provide protection against accidental electric shock. DO NOT remove the 3rd prong. See Grounding Instructions on the following pages.

• AVOID A DANGEROUS WORKING ENVIRONMENT. DO NOT use electrical tools in a damp environment or expose them to rain.

• DO NOT use electrical tools in the presence of fl ammable liquids or gasses.
• ALWAYS keep the work area clean, well lit, and organized. DO NOT work in an environment with floor surfaces that are slippery from debris, grease, and wax.
• KEEP VISITORS AND CHILDREN AWAY. DO NOT permit people to be in the immediate work area, especially when the electrical tool is operating.
• DO NOT FORCE THE TOOL to perform an operation for which it was not designed. It will do a safer and higher quality job by only performing operations for which the tool was intended.
• WEAR PROPER CLOTHING. DO NOT wear loose clothing, gloves, neckties, or jewelry. These items can get caught in the machine during operations and pull the operator into the moving parts. The user must wear a protective cover on their hair, if the hair is long, to prevent it from contacting any moving parts.
• CHILDPROOF THE WORKSHOP AREA by removing switch keys, unplugging tools from the electrical receptacles, and using padlocks.
• ALWAYS UNPLUG THE TOOL FROM THE ELECTRICAL RECEPTACLE when making adjustments, changing parts or performing any maintenance.

SAFETY INSTRUCTIONS

1. KEEP PROTECTIVE GUARDS IN PLACE AND IN WORKING ORDER.

2. AVOID ACCIDENTAL STARTING. Make sure that the power switch is in the "OFF" position before plugging in the power cord to the electrical receptacle.

3. REMOVE ALL MAINTENANCE TOOLS from the immediate area prior to turning "ON" the machine.

4. USE ONLY RECOMMENDED ACCESSORIES. Use of incorrect or improper accessories could cause serious injury to the operator and cause damage to the tool. If in doubt, check the instruction manual that comes with that particular accessory.

5. NEVER LEAVE A RUNNING TOOL UNATTENDED. Turn the power switch to the "OFF" position. DO NOT leave the tool until it has come to a complete stop.

6. DO NOT STAND ON A TOOL. Serious injury could result if the tool tips over, or you accidentally contact the tool.

7. DO NOT store anything above or near the tool where anyone might try to stand on the tool to reach it.

8. MAINTAIN YOUR BALANCE. DO NOT extend yourself over the tool. Wear oil resistant rubber soled shoes. Keep floor clear of debris, grease, and wax.

9. MAINTAIN TOOLS WITH CARE. Always keep tools clean and in good working order. Keep all blades and tool bits sharp, dress grinding wheels and change other abrasive accessories when worn.

10. EACH AND EVERY TIME, CHECK FOR DAMAGED PARTS PRIOR TO USING THE TOOL. Carefully check all guards to see that they operate properly, are not damaged, and perform their intended functions. Check for alignment, binding or breaking of moving parts. A guard or other part that is damaged should be immediately repaired or replaced.

11. DO NOT OPERATE TOOL WHILE TIRED, OR UNDER THE INFLUENCE OF DRUGS, MEDICATION OR ALCOHOL.

12. SECURE ALL WORK. Use clamps or jigs to secure the work piece. This is safer than attempting to hold the work piece with your hands.

13. STAY ALERT, WATCH WHAT YOU ARE DOING, AND USE COMMON SENSE WHEN OPERATING A POWER TOOL.

A moment of inattention while operating power tools may result in serious personal injury.

1. ALWAYS WEAR A DUST MASK TO PREVENT INHALING DANGEROUS DUST OR AIRBORNE PARTICLES, including wood dust, crystalline silica dust and asbestos dust. Direct particles away from face and body. Always operate tool in well ventilated area and provide for proper dust removal. Use dust collection system wherever possible. Exposure to the dust may cause serious and permanent respiratory or other injury, including silicosis (a serious lung disease), cancer, and death. Avoid breathing the dust, and avoid prolonged contact with dust. Allowing dust to get into your mouth or eyes, or lay on your skin may promote absorption of harmful material. Always use properly fitting NIOSH/OSHA approved respiratory protection appropriate for the dust exposure, and wash exposed areas with soap and water.

2. USE A PROPER EXTENSION CORD IN GOOD CONDITION. When using an extension cord, be sure to use one heavy enough to carry the current your product will draw. The table on the following page shows the correct size to use depending on cord length and nameplate amperage rating. If in doubt, use the next heavier gauge. The smaller the gauge number, the larger diameter of the extension cord. If in doubt of the proper size of an extension cord, use a shorter and thicker cord. An undersized cord will cause a drop in line voltage resulting in a loss of power and overheating.

USE ONLY A 3-WIRE EXTENSION CORD THAT HAS A 3-PRONG GROUNDING PLUG AND A 3-POLE RECEPTACLE THAT ACCEPTS THE TOOL'S PLUG.

SAFETY INSTRUCTIONS

ELECTRICAL SAFETY

WARNING: THIS TOOL MUST BE GROUNDED WHILE IN USE TO PROTECT THE OPERATOR FROM ELECTRIC SHOCK.

IN THE EVENT OF A MALFUNCTION OR BREAKDOWN, grounding provides the path of least resistance for electric current and reduces the risk of electric shock. This tool is equipped with an electric cord that has an equipment grounding conductor and requires a grounding plug (not included). The plug MUST be plugged into a matching electrical receptacle that is properly installed and grounded in accordance with ALL local codes and ordinances.

DO NOT MODIFY ANY PLUG. If it will not fit the electrical receptacle, have the proper electrical receptacle installed by a qualified electrician.

IMPROPER ELECTRICAL CONNECTION of the equipment grounding conductor can result in risk of electric shock. The conductor with the green insulation (with or without yellow stripes) is the equipment grounding conductor. DO NOT connect the equipment grounding conductor to a live terminal if repair or replacement of the electric cord or plug is necessary.

CHECK with a qualified electrician or service personnel if you do not completely understand the grounding instructions, or if you are not sure the tool is properly grounded when installing or replacing a plug.

USE ONLY A 3-WIRE EXTENSION CORD THAT HAS THE PROPER TYPE OF A 3-PRONG GROUNDING PLUG THAT MATCHES THE MACHINE'S 3-PRONG PLUG AND ALSO THE 3-POLE RECEPTACLE THAT ACCEPTS THE TOOL'S PLUG. *

REPLACE A DAMAGED OR WORN CORD IMMEDIATELY.

This tool is intended for use on a circuit that has an electrical receptacle as shown in FIGURE A. It shows a 3-wire electrical plug and electrical receptacle that has a grounding conductor. If a properly grounded electrical receptacle is not available, an adapter as shown in FIGURE B can be used to temporarily connect this plug to a 2-contact ungrounded receptacle. The adapter has a rigid lug extending from it that MUST be connected to a permanent earth ground, such as a properly grounded receptacle box. THIS ADAPTER IS PROHIBITED IN CANADA.

EXTENSION CORDS

A WARNING: THE USE OF AN EXTENSION CORD WITH THIS MACHINE IS NOT RECOMMENDED. For best power and safety, plug the machine directly into a dedicated, grounded electrical outlet that is within the supplied cord length of the machine.

This may be because the motor or frame have become loose from the base, or that the V-belt has stretched out due to the machine being used. In either case, re-adjustment of the V-belt is needed.

1. To gain access to the V-Belt (Part #8), the Belt Cover (#39) must be removed, by unscrewing the two hex head Screws (#112). FIG. 15.

2. On the cabinet top, under the sanding belt frame, there are two hex head Bolts and Nuts (#18, 19) that extend up from the cabinet surface. These connect to the motor frame and will adjust the tension of the V-Belt by pivoting the motor. FIG. 16, A.

Loosen the locking nuts and then rotate the bolts so that the motor frame is moved to put more, or less, tension on the V-Belt.

1. Tension, or the deflection of the V-belt should be about 1/4" to 3/8" when moderate pressure is applied onto the belt with your finger. FIG. 17.

2. Once the proper belt tension is achieved, tighten the hex head bolts to secure the motor frame in its new position.

3. Re-install the safety belt cover over the V-belt, that was removed in step 1 above.

REPLACING THE V-BELT

Should the rotation of the sanding belt or disc STOP, the cause may be that the V-belt is broken or has stretched out so much, that any tension adjustments do not work. In these cases, the V-belt must be replaced.

PLUGGED IN AND THE POWER SWITCH MUST BE IN THE OFF POSITION UNTIL ALL ADJUSTMENTS ARE COMPLETE.

1. Unscrew the Disc Frame from the sander's cabinet. Remove three screws - two on top of the frame (#38) and one longer screw from the interior of the frame (#91). FIG. 22.

2. On the cabinet top, under the sanding belt frame, there are two hex head Bolts and Nuts (#18, 19) that extend up from the cabinet surface. These connect to the motor frame and will adjust the tension of the V-Belt by pivoting the motor. FIG. 16, A, page 13.

Loosen the locking nuts and then rotate the bolts so that the motor frame is moved to release tension on the V-Belt.

To gain access to the lower drive Pulley and V-Belt, the bottom Base Cover (#3) must be removed.

1. Carefully tip the sander to one side to avoid any damage to the machine. Unscrew the four retaining Screws (#1) and remove the base cover. FIG. 23.

NOTE: For clarity, FIG. 24 is a bottom view of the sander with the base cover removed. It shows the motor, V-belt and pulleys.

1. Remove the old V-belt from the two drive pulleys, and install a new V-Belt. Make sure that there is some tension on the belt, so that it does not slip off as the sander parts are re-assembled.

NOTE: Both pulleys are pre-set at the factory and should be in-line with each other. If not, re-adjust one of the pulleys on their drive shaft. Loosen the hex set screw that holds the pulley to its shaft, move the pulley so that it is aligned with the other pulley, then re-tighten the set screw to lock it in position.

1. While the sander is still apart, set the belt tension. See page 13 for instructions on tightening the two bolts that apply belt tension. FIG. 17. The sander will have to be tipped back up to its normal position for this step.

2. Once the tension on the V-belt is set, re-assemble the sander parts by reversing steps 7 to 1 above.

The sander is now ready to plug in and use again.

OPERATION

CHANGING THE SANDING BELT

1. Remove the plastic Side Cover (#60) from the frame by unscrewing the knob (#78). FIG. 25.
2. Remove the Small Fence (#56). See page 9 for instructions on installing this part.
3. Slide Tension Lever (#71) to the right to release the belt tension. FIG. 26.

NOTE: Above the Tension Lever, there is a direction arrow. The sanding belt must run in the direction of this arrow so that the splice does not come apart. FIG. 26.

1. Remove the old belt by sliding it off to the left of the frame. Place the new sanding belt over the drums with the direction arrow pointing in the proper direction. See FIG. 27. Make sure the belt is centered on both drums.
2. Slide the tension lever to the left to apply tension to the belt. FIG. 26.
3. Re-install the small fence and side cover onto the frame (removed in Step 1 & 2).
4. Plug in the power cord. Turn the switch "ON" and note if the belt tends to move to the right or left on the drums. The belt should be running on the center of the drive drums. If it is not, the belt tracking needs adjustment. See below for instructions on tracking.

SANDING BELT TRACKING

1. Belt tracking on the center of the drive wheels is pre-set at the factory. If an adjustment need to be made, the sander must be turned on. FIG. 28.
2. • If the sanding belt moves toward the disc, slowly turn the Tracking Knob (#66) clockwise 1/4 turn.
3. If the sanding belt moves away from the disc, turn the tracking knob slowly counterclockwise 1/4 turn.
4. Slowly turn the belt tracking knob noting the belt movement. Re-adjust the tracking knob, as necessary, until the belt runs true in the center of the drums.

OPERATION

CHANGING THE SANDING DISC

The sandpaper disc can be removed with the table installed, FIG. 29, or with the table removed to give more working access to the disc, if needed. See pages 10 & 11 for table instructions.

1. Peel the used abrasive disc from the metal sanding disc plate. A putty knife may help in this process.
2. Make sure that the disc plate is clean of any residue. Mineral spirits will soften the PSA adhesives for its removal. Rotate the disc by hand may be necessary to get access to all of the disc surface.
3. Peel the protective backing from the new PSA 10" abrasive sanding disc, then center and press the sanding disc firmly onto the disc plate. See page 10.
4. Replace the sanding table if it was removed.

WARNING THE MACHINE MUST NOT BE PLUGGED IN AND THE POWER SWITCH MUST BE IN THE OFF POSITION UNTIL ALL ADJUSTMENTS ARE COMPLETE.

NOTE: Hook & Loop sanding discs cannot be used with this sander! Only 10" sanding discs with pressure sensitive adhesive (PSA) backing can be used.

DISC SANDING

WARNING: When sanding, always position your work on the downward, rotating side (left side) of the sanding disc. FIG. 30. The sanding action will then force the wood down, safely towards the table, where it can be controlled. Sanding on the right, upward rotating side of the disc is dangerous, as your work cannot be controlled and 'kick-back' may occur - the wood being forced up and out of your hands.

1. Depending on your work, set the Sanding Disc Table to the proper angle from 45^ to 90^ . FIG. 30, 31.
2. Once the table has been set for the correct sanding angle, and all fasteners are secure, the machine can be plugged in for operation.
3. Use the Miter Gauge (#80) for added control of the work piece during sanding. The miter gauge can also be set to various degree angles for maintaining accurate angles when sanding small or multiple parts.
4. Do not force the work piece into the sanding disc. Sand using light pressure, letting the sanding abrasives time to do their work!
5. Move your work piece slightly left and right on the disc, keeping to the left-of-center, downward side. Moving your work piece left and right on the disc will

help prevent resin or debris from building up on one area of the disc, and also helps to prevent burning of the sanded surface from excessive abrasive-action heat build-up.

FIG. 18

OPERATION

MITER GAUGE

The Miter Gauge (#110) can be used on the disc table, which has a slot to fit the miter gauge's bar. The miter gauge head can be set anywhere up to 45° (right or left) by loosening the lock-knob, setting the miter gauge head to the desired angle, and retightening the lock-knob. FIG. 32.

BELT SANDING

Always ensure the sander is unplugged prior to attempting any assembly, installation or changing of parts and accessories.

Position the sanding belt bed horizontally or vertically as needed for your sanding needs. See page 12. Once the correct sanding angle, and all fasteners are secure, the sander can be plugged in for operation.

Warning: To avoid injury from slips, jams or thrown pieces, adjust the sanding belt fence (#56) to clear the sanding surface by no more than 1/16th of and inch.

1. Hold the work piece firmly, keeping fingers away from the sanding belt.
2. Keep the work piece against the backstop and move it evenly across the sanding belt. Use extra caution when sanding very thin pieces. FIG. 33 & 34.
3. For sanding long pieces, remove the fence.
4. Do not force the work piece into the sanding belt. Sand using light pressure, letting the sanding abrasives time to do their work!
5. Move your work piece slightly left and right on the belt. This will help prevent resin or debris from building up on one area of the belt, and also helps to prevent burning of the sanded surface from excessive abrasive-action heat build-up.

SANDING CURVED EDGES

Sanding inside curves on your work piece and be done on the idler drum as shown. FIG. 35.

Always sand outside curves on your work piece with the sanding belt in vertical position, using the belt's fence for support. FIG. 34. Or sand your work on the left side of center on the sanding disc. FIG. 30 & 31.
