1. Introduction
The Wiltec Oscillating Spindle and Belt Sander is a versatile woodworking tool designed for precise sanding of various materials, primarily wood. This machine combines the functionality of both a spindle sander and a belt sander, offering flexibility for different sanding tasks. Its oscillating motion ensures smooth, even finishes and reduces the risk of gouging or uneven surfaces. The tiltable work table allows for angled sanding, expanding its application range for both straight and curved edges.
This manual provides essential information for the safe operation, setup, maintenance, and troubleshooting of your Wiltec sander. Please read it thoroughly before operating the machine to ensure proper use and to maximize its lifespan.

2. Safety Instructions
Always follow basic safety precautions when using electrical tools to reduce the risk of fire, electric shock, and personal injury.
2.1 General Safety Rules
- Read and understand all instructions before operating the sander.
- Wear appropriate personal protective equipment (PPE), including safety glasses, hearing protection, and a dust mask.
- Keep the work area clean and well-lit. Cluttered or dark areas invite accidents.
- Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust.
- Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.
- Always disconnect the power plug from the outlet before making any adjustments, changing accessories, or storing the tool.
2.2 Electrical Safety
- Power tool plugs must match the outlet. Never modify the plug in any way.
- Avoid body contact with grounded surfaces such as pipes, radiators, ranges, and refrigerators. There is an increased risk of electric shock if your body is grounded.
- Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
- Do not abuse the cord. Never use the cord for carrying, pulling, or unplugging the power tool. Keep cord away from heat, oil, sharp edges, or moving parts.
2.3 Personal Safety
- Stay alert, watch what you are doing, and use common sense when operating a power tool.
- Do not use the tool while tired or under the influence of drugs, alcohol, or medication.
- Dress properly. Do not wear loose clothing or jewelry. Keep your hair and clothing away from moving parts.
- Use dust extraction and collection facilities if provided. These can reduce dust-related hazards.

4. Setup
4.1 Unpacking and Inspection
- Carefully remove all components from the packaging.
- Inspect the machine for any shipping damage. If damage is found, do not operate the machine and contact customer support immediately.
- Verify that all listed components are present. Refer to the "Components Overview" section.
4.2 Assembly
The Wiltec sander comes largely pre-assembled. Minor assembly may be required for specific components or accessories.
- Place the sander on a stable, level workbench.
- Ensure the power switch is in the "OFF" position and the machine is unplugged.
- If using the spindle sanding function, ensure the appropriate sanding sleeve and corresponding table insert are installed.
- If using the belt sanding function, ensure the belt assembly is correctly positioned and the belt is tensioned.
4.3 Connecting to Power
Connect the power cord to a grounded 230V AC outlet. Ensure the circuit can handle the 500W power consumption of the sander.
5. Operating Instructions
5.1 General Operation
- Ensure the workpiece is free of nails, screws, or other foreign objects.
- Always hold the workpiece firmly against the work table.
- Apply light, even pressure when sanding. Excessive pressure can lead to poor results and motor strain.
- Move the workpiece smoothly across the sanding surface.
5.2 Spindle Sanding
The spindle sanding function is ideal for sanding curved edges and internal contours.
- Select the appropriate sanding sleeve diameter for your workpiece.
- Install the chosen sanding sleeve onto the spindle post.
- Ensure the correct table insert is in place to minimize the gap around the spindle.
- Turn on the machine.
- Carefully bring the workpiece into contact with the oscillating and rotating sanding sleeve.

5.3 Belt Sanding
The belt sanding function is suitable for sanding straight edges and larger flat surfaces.
- Ensure the belt sanding assembly is engaged.
- Check the tension and alignment of the sanding belt.
- Turn on the machine.
- Feed the workpiece smoothly against the moving sanding belt.

5.4 Tilting the Work Table
The work table can be tilted up to 45 degrees for bevel sanding.
- Loosen the table locking knob.
- Adjust the table to the desired angle using the angle scale.
- Tighten the table locking knob securely before operating.
6. Maintenance
Regular maintenance ensures optimal performance and extends the life of your sander.
6.1 Cleaning
- Always unplug the machine before cleaning.
- Use a brush or compressed air to remove sawdust from the machine, especially around the motor vents and sanding areas.
- Wipe down external surfaces with a damp cloth. Do not use solvents.
- Regularly empty the dust collection bag/system.
6.2 Sanding Sleeve/Belt Replacement
- Replace sanding sleeves and belts when they become worn or lose their abrasive quality.
- Refer to the machine's specific instructions for detailed steps on changing sleeves and belts. Ensure proper tensioning for belts.
6.3 Lubrication
The machine's internal components are generally sealed and do not require user lubrication. Do not attempt to lubricate internal parts unless specifically instructed by the manufacturer.
