GENERAL SAFETY RULES

• WARNING! Read all safety warnings and all instructions. Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.
• Safety is a combination of common sense, staying alert and knowing how your item works. The term “power tool” in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.

SAVE THESE SAFETY INSTRUCTIONS.

WORK AREA SAFETY

1. Keep work area clean and well lit. Cluttered or dark areas invite accidents.
2. Do not operate power tools in explosive atmo-spheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ig-nite the dust or fumes.
3. Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

ELECTRICAL SAFETY

1. Power tool plugs must match the outlet. Never mod-ify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock.
2. Avoid body contact with earthed or grounded surfac-es such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
3. Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of elec-tric shock.
4. Do not abuse the cord. Never use the cord for car-rying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.
5. When operating a power tool outdoors, use an ex-tension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
6. If operating a power tool in a damp location is un-avoidable, use a ground fault circuit interrupter (GFCI) protected supply. Use of a GFCI reduces the risk of elec-tric shock.

PERSONAL SAFETY

1. Stay alert, watch what you are doing and use com-mon sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inatten-tion while operating power tools may result in serious personal injury.
2. Use personal protective equipment. Always wear eye protection. Protective equipment such as a respira-tory mask, non-skid safety shoes and hearing protection used for appropriate conditions will reduce the risk of personal injury.
3. Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energizing power tools that have the switch on invites accidents.
4. Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.
5. Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
6. Dress properly. Do not wear loose clothing or jew-elry. Keep your hair and clothing away from moving parts. Loose clothes, jewelry or long hair can be caught in moving parts.
   • WARNING! Read all safety warnings and all instructions. Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.
   • Safety is a combination of common sense, staying alert and knowing how your item works. The term “power tool” in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.
7. If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce dust-related hazards.

POWER TOOL USE AND CARE

1. Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed.
2. Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
3. Disconnect the plug from the power source and/or the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.
4. Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained us-ers.
5. Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool’s opera-tion. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.
6. Keep cutting tools sharp and clean. Properly main-tained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
7. Use the power tool, accessories and tool bits, etc. in accordance with these instructions, taking into ac-count the working conditions and the work to be per-formed. Use of the power tool for operations different from those intended could result in a hazardous situa-tion.
8. Use clamps to secure your workpiece to a stable surface. Holding a workpiece by hand or using your body to support it may lead to loss of control.
9. KEEP GUARDS IN PLACE and in working order.

SERVICE

• Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is main-tained.

ELECTRICAL INFORMATION

DOUBLE-INSULATED CHARGER

• The tool’s electrical system is double-insulated where two systems of insulation are provided. This eliminates the need for the usual three-wire grounded power cord.
• Double-insulated tools do not need to be grounded, nor should a means for grounding be added to the product. All exposed metal parts are isolated from the internal metal components with protecting insulation.
• IMPORTANT: Servicing a double-insulated product requires extreme care and knowledge of the system, and should be done only by qualified service personnel using identical replacement parts. Always use original factory replacement parts when servicing.

1. Polarized Plugs. To reduce the risk of electric shock, this equipment has a polarized plug (one blade is wider than the other). This plug will fit in a polarized outlet only one way. If the plug does not fit fully in the outlet, reverse the plug. If it still does not fit, contact a qualified electrician to install a proper outlet. Do not modify the machine plug or the extension cord in any way.
2. Ground fault circuit interrupter protection (GFCI) should be provided on the circuit or outlet used for this power tool to reduce the risk of electric shock.
3. Service and repair. To avoid danger, electrical appliances must only be repaired by a qualified service technician using original replacement parts.

GUIDELINES AND RECOMMENDATIONS FOR EXTENSION CORDS
When using an extension cord, be sure to use one heavy enough to carry the current your product will draw. An undersized cord will cause a drop in line voltage, resulting in loss of power and overheating. The table below shows the correct size to be used according to cord length and ampere rating. When in doubt, use a heavier cord. The smaller the gauge number, the heavier the cord.

1. Examine extension cord before use. Make sure your extension cord is properly wired and in good condition. Always replace a damaged extension cord or have it repaired by a qualified person before using it.
2. Do not abuse extension cord. Do not pull on cord to disconnect from receptacle; always disconnect by pulling on plug. Disconnect the extension cord from the receptacle before disconnecting the product from the extension cord. Protect your extension cords from sharp objects, excessive heat and damp/wet areas.
3. Use a separate electrical circuit for your tool. This circuit must not be less than a 12-gauge wire and should be protected with a 15A time-delayed fuse. Before connecting the motor to the power line, make sure the switch is in the OFF position and the electric current is rated the same as the current stamped on the motor nameplate. Running at a lower voltage will damage the motor.

ASSEMBLY & ADJUSTMENTS

WARNING! To prevent accidental starting, make sure the machine is switched OFF and the power plug is disconnected before assembly, setting up or making adjustments.

ACCESSORY SELECTION

• Refer to the packing list diagram on page 10 to ensure that you are using the proper sizes of throat plates, drums and washers for each respective sanding sleeve. To ensure the workpiece can be properly supported and to mini-mize clearance, use the throat plate that matches the drum and sleeve that you’ll be working with. The size of the throat plate is marked on the plate’s surface. For horizontal sanding, use throat plates with circle openings; for bevel sanding, use plates with an oblong openings.
• NOTE: The smallest size sanding sleeve does not include a drum. It goes directly onto the bare spindle.

INSTALLING THE ACCESSORIES

1. Disconnect the machine from the power source.
2. Slide the lower spindle washer (Fig. 2 – 1) over the spin-dle shaft.
3. Install the preferred rubber drum (Fig. 2 – 2) onto the spindle shaft, followed by the corresponding sanding sleeve (Fig. 2 – 3) and throat plate (Fig. 2 – 4). Make sure the printed side of the throat plate is facing up.
   • NOTE: The 1/2″ sleeve should be installed directly onto the spindle.
4. Secure the sanding accessories in place with the cor-responding washer (Fig. 2 – 5). Tighten the spindle nut on top (Fig. 2 – 6) with the spindle nut wrench until the sand-ing drum creates equal pressure to all sides of the sanding sleeve. The sleeve should not be able to freely rotate with-out also rotating the sanding drum.

WARNING! To prevent accidental starting, make sure the machine is switched OFF and the power plug is disconnected before assembly, setting up or making adjustments.

MACHINE MOUNTING

• For safe operation, the machine must be secured onto a flat, secure workbench or stand. The base of the machine has four 6 mm mounting holes. Place the sander on the mounting surface, and insert a pencil through the mounting holes to mark the hole locations. Remove the sander and drill out the mounting holes. Then align the sander base over the mounting holes and secure the machine using four mounting bolts, washers, locking washers and hex nuts (mounting hardware not included). Securely tighten the hex nuts.
• For temporary mounting, secure the sander to a mobile mounting board and use 2 large C-Clamps to secure the mounting board to a solid surface.
• TIP: Your spindle sander is compatible with the WEN 6588 Multipurpose Planer Stand, available at wenproducts.com. Forget measuring and drilling holes on your workbench, simply mount your machine onto the stand with pre-drilled holes, and transport your machine around the workshop with ease.

ADJUSTING THE WORK TABLE BEVEL

• The work table has the capacity to tilt from 0 to 45 degrees for sanding bevels on your workpiece. For any bevel sand-ing operation, you must use the throat plate with an oblong-shaped opening (Fig. 3 – 1).

To adjust the table bevel:

1. Disconnect the machine from the power source.
2. Loosen the table bevel knobs (Fig. 3 – 2) on both sides of the sander.
3. Tilt the table until the pointer is indicating the desired angle on the bevel gauge.
4. Re-tighten both bevel knobs.

SQUARING THE TABLE TO THE SPINDLE
When sanding with the work table in the horizontal (0°) position, make sure that the table surface is square to the sanding spindle. With the sanding drum and sleeve installed, check the alignment using a machinist’s or combina-tion. The square should be flat against the table and the spindle (Fig. 4). Periodically check for proper alignment between the table and spindle. If the table and spindle are not square, adjust as follow:

1. Check that the table is in the 0-degree position.
2. Loosen both table bevel knobs (Fig. 5 – 1).
3. Adjust the corresponding fine adjustment nut beneath the work table (Fig. 5 – 2) to bring the table perpendicular to the spindle.
4. Lock both table bevel knobs and use a square to re-check table/spindle alignment.
5. Repeat steps 2 – 4 until the table surface and sanding spindle are perpendicular.

DUST COLLECTION

WARNING! Sanding operations are dusty and can produce particles that are harmful to your health. Al-ways wear a dust mask and use an adequate dust col- lection system.

To connect a dust collection system to the machine:

1. Fit a 2-inch dust hose (not included) over the dust port (Fig. 5 – 3) and secure the hose in place with a hose clamp as needed.
2. Tug the hose to make sure the fitting is tight. A tight fit is necessary for proper performance.
3. Connect the other end of the dust hose to the dust col-lection system of your choice. A dust port adapter may be needed (not included), depending on the inlet size of your dust extractor.

NOTE: Failure to use a dust collector can cause sawdust to build up in the machine, possibly leading to premature fail-ure. Failure to use a dust collector will void the warranty. Keep your sander clean!

OPERATION

WARNING! Do not plug in or turn on the tool until it is fully assembled according on the instructions. Failure to follow the safety instructions may result in serious personal injury.
