Using the Clarke OBS-18 Orbital Floor Sander
To get the most out of your Clarke OBS-18 orbital floor sander, it's essential to use it correctly and maintain it properly. Here are some tips for using and caring for your OBS-18:
Sanding Techniques
When using the OBS-18, always start with a coarse grit sandpaper (e.g., 40 or 60 grit) for heavy-duty sanding, and gradually move to finer grits (e.g., 80, 120, and 240) for finishing. Keep the sander flat on the surface and use even, overlapping strokes. Avoid applying too much pressure, as this can cause the sander to gouge the surface.
Maintenance Tips
| Maintenance Task | Frequency | Steps |
|---|---|---|
| Cleaning | After each use | Remove dust from the sander using a brush or compressed air. Clean the dust extraction port and ensure it's free of debris. |
| Inspection | Monthly or after 20 hours of use | Check the sanding pad, belt, and bearings for signs of wear. Tighten any loose screws or bolts and lubricate moving parts as needed. |
