Key Components:

• Sanding Base: The flat surface where the sandpaper is attached.
• Dust Collector: A removable container designed to collect sanding dust, improving visibility and reducing airborne particles.
• Power Switch: Controls the ON/OFF function of the sander.
• Paper Clamps (for regular sandpaper): Metal clamps located on the sides to secure standard sandpaper sheets.
• Hook-and-Loop Base (for adapted sandpaper): A base designed for quick attachment and removal of sandpaper with a hook-and-loop backing and dust extraction holes.

Setup

Attaching Sandpaper:

1. For Standard Sandpaper Sheets:
   • Ensure the sander is unplugged.
   • Lift the metal clamps on both sides of the sanding base.
   • Insert one end of the sandpaper sheet under one clamp and secure it.
   • Stretch the sandpaper tightly across the sanding base and insert the other end under the second clamp, securing it firmly.
   • Ensure the sandpaper is taut and flat against the base.
2. For Hook-and-Loop Sandpaper (with dust holes):
   • Ensure the sander is unplugged.
   • Align the holes on the sandpaper with the holes on the sander's hook-and-loop base.
   • Press the sandpaper firmly onto the base to ensure a secure attachment.

Attaching the Dust Collector:

• Locate the dust port at the rear of the sander.
• Slide the dust collector firmly onto the dust port until it clicks into place or feels secure.
• Empty the dust collector regularly for optimal performance and to prevent clogging.

Operating Instructions

1. Preparation: Ensure the workpiece is securely clamped and stable. Wear appropriate personal protective equipment (PPE), including eye protection and a dust mask.
2. Power Connection: Plug the sander into a suitable 120V power outlet.
3. Starting the Sander: Hold the sander firmly with both hands. Place the sanding base flat on the surface to be sanded. Press the ON/OFF switch to start the tool.
4. Sanding Technique: Apply light, even pressure. Move the sander in long, overlapping strokes. Avoid pressing down too hard, as this can reduce efficiency and damage the workpiece or sander.
5. Stopping the Sander: Lift the sander from the workpiece, then press the ON/OFF switch to turn it off. Wait for the sanding pad to stop completely before setting the tool down.

Maintenance

• Cleaning: Regularly clean the sander's exterior with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners.
• Dust Collector: Empty the dust collector frequently. A full dust collector reduces sanding efficiency and increases dust exposure.
• Air Vents: Keep the motor's air vents clear of dust and debris to prevent overheating. Use compressed air to blow out vents if necessary.
• Sandpaper Replacement: Replace worn sandpaper promptly. Using dull sandpaper can strain the motor and produce poor results.
• Cord Inspection: Periodically inspect the power cord for damage. If damaged, have it repaired by a qualified service technician.
• Professional Maintenance: The product includes a first year of free maintenance. Contact Stanley authorized service centers for professional servicing.
