3. මෙහෙයුම් උපදෙස්
For optimal results and to prevent damage to the paint surface, adhere to the following operating guidelines:
- මතුපිට සකස් කිරීම: Ensure the vehicle's paint surface is clean, dry, and decontaminated before beginning any polishing work. Mask off any trim or sensitive areas.
- Compound Application: Apply 4-5 pea-sized drops of RUPES DA Coarse Compound directly onto the pad. For larger panels, you may need to apply more compound as you work.
- Spreading the Compound: Place the pad flat on the paint surface before turning on the polisher. Spread the compound over a small working area (approximately 2x2 feet) on a low speed setting (e.g., speed 1-2).
- ඔප දැමීමේ තාක්ෂණය: Increase the polisher speed to the recommended setting for defect removal (typically speed 4-6 for RUPES polishers). Work in a cross-hatch pattern, applying light to moderate pressure. Ensure the pad remains flat on the surface at all times.
- අතිච්ඡාදනය වන අවසරපත්: Overlap each pass by approximately 50% to ensure even coverage and consistent defect removal.
- නිරීක්ෂණ උෂ්ණත්වය: Periodically check the temperature of the working surface with your hand. If the surface becomes too hot to touch, reduce pressure or allow the area to cool.
- Wipe Off Residue: After completing a section, turn off the polisher before lifting it from the surface. Use a clean, soft microfiber towel to wipe away compound residue.

4. නඩත්තු කිරීම
Proper maintenance extends the life of your RUPES DA LHR21 Blue Coarse Pad and ensures consistent performance:
- එක් එක් භාවිතයෙන් පසු පිරිසිදු කිරීම: Immediately after each use, clean the pad to prevent compound from drying and hardening within the foam cells.
- පිරිසිදු කිරීමේ ක්රම:
- සම්පීඩිත වාතය: For light residue, use compressed air to blow out compound from the pad while it's still on the polisher, running at a low speed.
- Pad Brush: Use a dedicated pad cleaning brush to agitate and remove dried compound from the pad surface.
- සේදීම: For thorough cleaning, hand wash the pad with warm water and a mild pad cleaner or dish soap. Gently squeeze the pad to work the cleaner through the foam. Rinse thoroughly until all soap residue is gone.
- වියළීම: After washing, squeeze out excess water. Allow the pad to air dry completely in a clean, well-ventilated area, away from direct sunlight or heat. Do not machine dry.
- ගබඩා: Store clean, dry pads in a sealed container or bag to protect them from dust and contaminants.
- පරීක්ෂාව: Regularly inspect pads for signs of wear, such as tears, hardening, or a flattened foam structure. Replace worn pads to maintain performance and prevent paint damage.
