Troubleshooting Your B37S Massage GunUpdated 18 days ago

Work through the checks below for your Ekrin B37S. If you notice damage, unusual heat, or persistent abnormal noise, stop using the device and contact support.

Device will not turn on or charge

1. Check the charging guide in your model category and use the correct power source. Use the correct Ekrin 26V DC / 900mA adapter.
2. Check connections and try a different outlet or compatible power source. Inspect the cable and port for visible damage; keep the port dry and do not insert tools into it.
3. Allow a depleted battery time to charge, then disconnect the charger before testing the device.
4. Use the power control as shown in your model’s manual. Check a bottom ON/OFF switch if your version has one.

Head is loose, stuck, or noisy

Turn the device off before changing or checking an attachment.

With the device off, align the marks on the locking head and port, insert the head, and rotate clockwise about 90 degrees to lock. Turn it back to release the lock before withdrawing it. Never force a locked head straight out.

Check for debris or visible wear on the head and connector, and wipe clean with a dry cloth. Do not use tools or excessive force. If the head stays loose or cannot be removed normally, contact support. If unusual noise continues with a correctly fitted head, stop use.

Weak power or unexpected shutdown

• Check the battery and recharge if needed.
• Reduce pressure and let the head move gently over the muscle.
• Turn the device off and let it cool before trying again if it feels hot.
• Some shutdowns are protective or timed. Check your model’s manual for its operating limits; persistent early shutdowns need support.

Session limits

Follow your model’s manual for treatment duration and session limits. Keep the head moving; stop if treatment causes pain or discomfort.

Use the manual for your model and generation for its charging indicators and operating instructions.
