Troubleshooting Your Ekrin Athletics B37 Massage GunUpdated 19 days ago

Work through the checks below for your Ekrin B37. If you notice damage, unusual heat, or persistent abnormal noise, stop using the device and contact support.

First identify your B37

B37 v1 has a round barrel charging socket and push-fit heads. B37 v2 has USB-C PD charging and locking heads. Follow the instructions for your physical port and connector, rather than purchase date alone.

Device will not turn on or charge

1. Check the charging guide in your model category and use the correct power source. Use the original 26V DC / 900mA barrel adapter for v1; use the supplied cable and a suitable USB-C PD source for v2.
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.

B37 v1: Push-fit heads insert and pull straight out. B37 v2: Align the marks, insert the head, and rotate clockwise about 90 degrees to lock. Turn it back to release the lock before withdrawing it. Never pull a locked head out by force.

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

Our website recommends 15 seconds to two minutes per muscle group and no more than 15 minutes per session. 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.
