Frequently Asked Questions - Digital Series DT650 Horizon Fitness
How do I assemble the Horizon Fitness DT650 treadmill?

What is the maximum weight capacity?

How do I lubricate the running belt?
Every 3 months or after 150 miles, apply 100% silicone lubricant under the belt. Loosen the belt, apply lubricant, then run at low speed to distribute.
Why does the treadmill stop suddenly?
Check the safety key: it must be attached to the console and clipped to your clothing. Also ensure the power cord is secure and the circuit breaker hasn't tripped.
How do I adjust the belt tension?
Use the allen wrench to turn the rear roller bolts equally. Tighten both sides a quarter turn at a time until the belt does not slip. Avoid overtightening.
Can I connect my phone to the treadmill?
Yes, the DT650 has Bluetooth to sync with apps like Zwift, Peloton, or Horizon's own app. Also has a USB port for charging.
What does the error code 'E1' mean?
Error E1 usually indicates a motor communication issue. Try resetting the treadmill: unplug for 60 seconds, then plug back in. If persists, contact support.
How do I fold the treadmill?
The DT650 uses the SoftDrop folding system. Lift the deck until it locks. To unfold, press the release lever and guide the deck down slowly.
What kind of maintenance does the treadmill need?
Regularly clean the belt and deck, vacuum under the motor cover, lubricate the belt every 3 months, and check that all bolts are tight.
Is the treadmill noisy?
The DT650 is designed for quiet operation, but some noise is normal. Ensure the floor is level and use a mat to reduce vibration. Lubricate the belt if squeaking occurs.
