Care Guide

BossHorn is designed for durability and ease of use, requiring no regular maintenance. However, follow these simple care tips to ensure optimal performance and longevity:

1. Avoid Overheating

• If you continuously press the trigger, the air compressor may heat up.

• Allow it to cool down between extended uses to prevent overheating.

2. Remove the Battery When Not in Use

• Always disconnect the battery when storing your BossHorn.

• This prevents accidental activation and battery drainage over time.

3. Store in a Dry, Cool Place

• Keep your BossHorn indoors or in a protected area to avoid moisture buildup.

• While it is water-resistant, excessive exposure to water can damage electronic components.

4. Use the Right Battery

• Only use same-brand or compatible aftermarket batteries for optimal power.

• Store batteries fully charged before long-term storage.

5. Keep It Clean

• If needed, wipe down the horn with a dry or slightly damp cloth to remove dust.

• Avoid using harsh chemicals or soaking in water.

Following these simple steps will keep your BossHorn ready to blast whenever you need it! 🚂🔊
