How Do I Troubleshoot a Nautilus Treadmill?

By Amanda Goldfarb

Nautilus designs its treadmills with its Softrak suspensions, which reduces the impact on your joints during exercise. All of its treadmills also come preloaded with workouts to help you in your pursuit of health. Like any piece of electrical workout equipment, the Nautilus does occasionally have minor maintenance issues. Most of the time, these issues can be solved by simply tightening a bolt or lubricating the belt of the treadmill.

Treadmill Doesn't Turn On

Flip the power switch located at the front of the treadmill to the "On" position. Turn the unit off if the treadmill does not respond. Check the power cord to make sure it is securely plugged into the wall outlet. Also, check that the power cord is securely inserted into the front of the machine.

Test the outlet to ensure it is functioning properly by plugging another object into the outlet. Also, some outlets are controlled by switches. If this is the case, ensure the switch is flipped to the "On" position. If the outlet is still not working, you will need to use a different outlet to power your Nautilus Treadmill.

Clear anything away from the safety key port and make sure the key has been fully inserted into the slot. The belt will not function if the key is not properly in place. When the key is in place it signals the user is on the treadmill and ready to begin moving, this is a safety feature of the treadmill. Likewise, if the key is removed from the port at any point during operation, the belt will immediately shut off.

Belt Issues

Stabilize the treadmill by adjusting the front supports of the machine located under the base. Turn them to the right to shorten them or to the left to lengthen them. Make sure both supports are the same length, as uneven supports will cause the treadmill to wobble.

Adjust the belt tension. If the belt is excessively loose, the belt will slip while it is in use. If the belt is overly tightened it will cause the motor to strain while in use. Locate the tension adjustment bolts on the side panels of the treadmill. Use a 6 mm hex key tool to adjust the bolts. Turn the key to the right to tighten the belt, and turn it to the left to loosen the belt.

Center the belt of the treadmill. Often, the way you run or use the treadmill while it is off balance can cause the belt to move out of alignment. Set the treadmill to 3 miles per hour and press "Start." Watch the belt carefully and note which direction the belt is moving. If the belt is moving to the left, turn the adjustment belt, located at the back of the treadmill, to the right 1/4 of a turn. If the belt is moving to the right, turn the bolt 1/4 of a turn to left.

Heart Rate Monitor Doesn't Function

Unplug the heart rate monitor from the console of the machine. Check the wires for any frayed or broken leads, which would indicate that the monitor needs to be replaced. If you find nothing is broken, plug the monitor back into the treadmill's console. Ensure that the monitor is securely connected to the machine.

Turn off anything that emits an electrical signal within 6 feet of the treadmill. This includes radios, televisions, microwaves, computers and gaming consoles. The electrical signals that come from these items may interfere with the ability of the heart rate monitor to pick up the electrical signals of your heart.

Moisten your skin by applying a small amount of water or an electrode cream in the area you will be placing the transmitter for the heart rate monitor. Most times when the heart rate monitor is not functioning properly it is due to rough, dry skin impeding the electrical signal.

E1 Error Indicated

Unplug the power cord from the wall. Disconnect the other end of the power cord from the front power port of the treadmill.

Lift the belt and inspect for any wear to the deck of the treadmill. If you note any unusual wear you will need to contact Nautilius Customer Service to have your treadmill repaired. If no wear is noted, apply a thin layer of a silicone-based lubricant to the deck of the treadmill. The lubricant should cover the width of the underside of the belt. Nautilus recommends Lube-and-Walk lubrication kit.

Insert the power cord back into the treadmill, and then plug it back into the power source.

Staying to the side of the treadmill, turn the machine on the lowest speed setting. Leave the treadmill on for 15 seconds to allow the lubricant to be distributed evenly.

Turn off the treadmill and use a towel to wipe any excess lubricant off the treadmill.
