4. Setup and Adjustment
4.1 Headgear Adjustment
Proper adjustment of the headgear is crucial for comfort and stability during use.
- Place the helmet on your head.
- Adjust the top strap to ensure the helmet sits comfortably and securely.
- Use the rear knob to tighten or loosen the headband for a snug fit.
- Adjust the side pivots to control the helmet's tilt and viewing angle.
- Ensure the soft padded front and rear headband sections are positioned correctly to reduce pressure points.

4.2 Battery Installation/Check
The helmet is powered by solar cells and a replaceable CR2450 lithium battery. The battery is typically pre-installed.
- Ensure the battery is correctly installed with the correct polarity.
- The solar cells assist in powering the auto-darkening filter and extend battery life.
- If the auto-darkening function is inconsistent or fails, replace the CR2450 battery.
4.3 Lens Installation/Replacement
The helmet comes with three replacement lenses. These are typically clear cover lenses that protect the auto-darkening filter from scratches and spatter.
- Carefully remove the old cover lens by unclipping it from the helmet frame.
- Clean the auto-darkening filter if necessary.
- Insert a new cover lens, ensuring it is securely clipped into place.
The helmet is also compatible with magnifying (cheater) lenses. These can be inserted into a dedicated slot behind the auto-darkening filter.

5. Operating Instructions
5.1 Auto-Darkening Function
The helmet features a high-end auto-darkening lens with 4 premium arc sensors.
- The lens switches from light to dark in approximately 1/25000 seconds upon detecting an arc.
- The 1/1/1/1 optical clarity lens and true color technology provide a clear and realistic view of the workpiece.

5.2 Shade and Sensitivity Adjustment
The helmet allows for easy adjustment of shade and sensitivity to suit different welding processes and ambient light conditions.
- Shade Control: The dark state level is adjustable from DIN 9 to DIN 13 for welding, and DIN 4 for grinding. Use the external knob to select the appropriate shade.
- Sensitivity Control: Adjust the sensitivity to control how quickly the filter reacts to light. Higher sensitivity is suitable for low amperage TIG welding or when the arc is partially obscured.
- Delay Control: Adjust the delay time for the filter to return to the light state after the arc ceases. A longer delay is useful for high amperage welding to prevent eye fatigue from afterglow.

5.3 Application Modes
The HSH-S800 Skeleton Knight helmet is suitable for a wide range of applications:
- Welding: Ideal for TIG, MIG, and ARC welding processes. Adjust shade settings according to the amperage and material.
- Grinding: Switch to Grind Mode (DIN 4) for clear viewing during grinding operations. Ensure the helmet is in grind mode before starting to avoid accidental darkening.
- Cutting: Can be used for plasma cutting applications.

6. Maintenance
6.1 Cleaning
- Helmet Shell: Clean the helmet shell with a mild soap and water solution. Avoid harsh chemicals or abrasive cleaners.
- Lenses: Gently wipe the inner and outer cover lenses with a soft, clean cloth. For stubborn dirt, use a lens cleaning solution specifically designed for plastics. Do not use abrasive materials or solvents on the auto-darkening filter.
- Sensors: Keep the arc sensors clean and unobstructed to ensure proper auto-darkening function.
6.2 Battery Replacement
The CR2450 lithium battery should be replaced when the low battery indicator appears or if the auto-darkening function becomes unreliable.
- Locate the battery compartment, usually on the auto-darkening filter unit.
- Open the compartment and carefully remove the old CR2450 battery.
- Insert a new CR2450 battery, ensuring correct polarity (+ side up).
- Close the battery compartment securely.
6.3 Storage
- Store the helmet in a clean, dry place away from direct sunlight and extreme temperatures.
- Protect the lenses from scratches by storing the helmet in a protective bag or case.
