3. What's in the Box
Your RUPES LHR 15ES Big Foot Random Orbital Polisher package includes the following components:
- 1 x RUPES LHR 15ES Polisher Unit
- 1 x 980.027N 125mm/5in Backing Plate
Note: Polishing pads and compounds are sold separately.
4. Setup
Attaching the Backing Plate:

- Align the 125mm/5in backing plate (model 980.027N) with the spindle on the polisher.
- Securely screw the backing plate onto the spindle until it is hand-tight. Do not overtighten.
Attaching Polishing Pads:
The polisher is designed to accommodate 6-inch polishing pads. These pads attach to the backing plate via a hook-and-loop (Velcro) system.
- Ensure the backing plate is clean and free of debris.
- Align the polishing pad centrally with the backing plate.

5. Operating Instructions
Powering On and Off:
- Connect the polisher to a suitable power outlet.
- To start the polisher, press the trigger switch. The tool features a soft start, which provides an acceleration ramp to prevent accidental dispersion of product.
- To maintain continuous operation without holding the trigger, engage the trigger lock button (refer to Figure 2).
- To turn off the polisher, release the trigger switch or disengage the trigger lock.

Adjusting Speed:
The RUPES LHR 15ES features a variable speed dial, allowing you to adjust the oscillation speed from 1 to 6 settings. This enables precise control based on the task and product being used.
- Locate the speed dial on the top of the polisher body.
- Rotate the dial to select the desired speed setting. Lower settings are typically used for spreading product or finishing, while higher settings are for compounding and defect removal.

Polishing Technique:
- Apply a small amount of polishing compound or polish directly to the pad.
- Place the pad flat on the surface to be polished before turning on the tool.
- Start the polisher on a low speed to spread the product evenly over a small section (e.g., 2x2 feet).
- Increase the speed to the desired setting and work in overlapping passes, maintaining even pressure.
- The anti-spinning feature helps prevent high-speed rotations, reducing the risk of scratches.
- The electronic feedback control maintains consistent power and speed even when pressure is applied.
- Avoid tilting the polisher, as this can concentrate pressure and heat, potentially damaging the paint.
6. Maintenance
Cleaning the Polisher:
- Always unplug the tool before cleaning.
- Wipe down the exterior of the polisher with a clean, damp cloth. Avoid using harsh chemicals or solvents.
- Ensure ventilation openings are clear of dust and debris to prevent overheating.
Pad Care:
- Remove pads from the backing plate immediately after use. The hook-and-loop material on the backing plate can be aggressive, and leaving pads attached for extended periods may cause them to bond or rip upon removal.
- Clean pads thoroughly after each use according to the pad manufacturer's instructions.
- Inspect pads for wear, tear, or contamination before each use. Replace damaged pads.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
