Horizon Fitness 7.8AT 2019 Owner's Manual

To assemble the Horizon Fitness 7.8AT treadmill, start by laying out all the parts and tools included in the package. Follow the step-by-step instructions provided in the manual, making sure to tighten all bolts and screws securely. Ensure the treadmill is on a level surface before use.
If the treadmill belt slips, first check the tension of the belt. Adjust it by using the tension screws located at the rear of the treadmill. Turn the screws clockwise to tighten and counterclockwise to loosen. Ensure the belt is centered after adjustment.
It is recommended to lubricate the treadmill belt every three months or after 150 miles of use. Use a silicone-based lubricant and follow the instructions in the user manual for proper application.
A sudden stop can be caused by a loose power connection, an overloaded circuit, or a safety key dislodgement. Check the power cord, ensure the safety key is in place, and avoid using an extension cord.
To calibrate the speed, enter the settings mode on the console, select speed calibration, and follow the on-screen prompts. Ensure the treadmill is on a level surface during calibration for accurate results.
Use a soft cloth dampened with a mild cleaning solution to wipe down the treadmill after each use. Avoid using abrasive cleaners. Clean the belt and deck area regularly to prevent dust buildup.
If the display is not working, check the power source, ensure the safety key is inserted, and inspect the console cable connections. If the issue persists, a technician may need to inspect the console.
Regular maintenance for the motor includes keeping it clean and ensuring proper ventilation. Periodically inspect the motor area for dust and debris, and vacuum it out if needed.
Adjust the incline using the controls on the console. The treadmill offers various incline levels that can be changed during your workout for added intensity and variety.
Unusual noises can be caused by loose parts, improper belt tension, or lack of lubrication. Check for loose bolts, adjust the belt tension, and lubricate the deck following the manufacturer's guidelines.
