4. Setup
Attaching Sandpaper
The SRE 4350 TurboTec features a robust clamping system for standard sandpaper sheets and a hook-and-loop system for quick-change sanding pads.
- For Hook-and-Loop Sanding Pads: Align the sanding pad with the sanding plate and press firmly to secure. Ensure the holes on the sanding pad align with the dust extraction holes on the plate.
- For Clamp-on Sandpaper: Open the clamping levers on both sides of the sanding plate. Insert the sandpaper sheet, ensuring it is taut and centered. Close the clamping levers securely.
Attaching Auxiliary Handle
The detachable auxiliary handle can be attached to the front of the sander for improved control and comfort during operation. Loosen the handle's locking mechanism, slide it onto the designated mounting point, and tighten the mechanism until secure.
Connecting Dust Bag / Extraction
Attach the textile dust bag to the dust extraction port at the rear of the sander. For optimal dust collection, connect the sander to an external dust extraction system using a suitable adapter (not included).
5. Operating
Powering On/Off
Connect the power cord to a suitable power outlet. To turn the sander on, press the ON/OFF switch. To turn it off, press the switch again.
Adjusting Oscillation Speed
The SRE 4350 TurboTec features variable oscillation speed, ranging from 8400 to 22000 oscillations per minute. Use the speed adjustment dial to select the appropriate speed for your material and desired finish. Lower speeds are suitable for delicate work and polishing, while higher speeds are for rapid material removal.
Sanding Techniques
- Always start the sander before placing it on the workpiece and lift it off before switching it off.
- Apply even, moderate pressure. Excessive pressure will reduce sanding efficiency and may damage the tool or workpiece.
- Move the sander in smooth, overlapping passes across the surface.
- For best results, sand with the grain of the wood.
6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your sander.
Cleaning the Tool
- After each use, disconnect the sander from the power supply.
- Wipe down the exterior of the tool with a clean, damp cloth. Do not use harsh cleaning agents or solvents.
- Clean the ventilation slots regularly to prevent overheating.
Dust Bag Emptying
Empty the textile dust bag frequently to maintain effective dust collection and prevent clogging. Detach the bag, empty its contents, and reattach securely.
Checking Wear Parts
- Sanding Pad: Inspect the hook-and-loop surface of the sanding pad for wear or damage. A worn pad will not hold sandpaper securely. Replace if necessary.
- Power Cord: Regularly check the power cord for any signs of damage. If damaged, have it replaced by a qualified technician.
