Approved Cleaners and Proper Cleaning Technique

Horizon recommends using a mild soap and water solution (1:10 soap to water dilution) for cleaning surfaces. To disinfect surfaces, distilled vinegar and water solution (1:20 vinegar to water dilution) can be used along with other store-bought disinfectants. Make sure you are using a diluted disinfectant
solution. Be careful when choosing your disinfectant however as strong concentrate disinfectants can damage plastics and metal surfaces over time.

Always spray a clean cloth then wipe surfaces. NEVER spray the frame or console directly. Spraying directly on the unit can cause corrosion over time as overspray occurs, and it is not wiped off.

Touchscreen consoles – to clean, use a micro-fiber cloth and an LCD screen cleaner

Preventive Maintenance

Before performing any maintenance, unplug the power cord from the outlet and wait 2-3 minutes to allow power to dissipate from all the electronics.

Move treadmill and vacuum under it                        
Clean console and hand grips with approved cleaner                        
Wipe entire frame and shrouds with approved cleaner                        
Inspect power cord for damage                        
Test the emergency stop & inspect tether/clip                        
Inspect frame bolts to ensure they are secure - see Frame Bolts                        
Test running belt tension and check alignment                        

IMPORTANT: For silicone running surfaces, it’s important to reapply silicone every 150 mi/241 km or 3 months. Refer to Running Deck/Belt Lubrication for more detail. For waxed running surfaces, please do not add anything as these surfaces were designed to be maintenance-free.



Remove the motor cover and vacuum entire area with a soft-bristled vacuum attachment. Be careful not to hit any wires or damage electronic connectors        
Using a can of compressed air, blow dust out of the speed sensor – see figure 1        
With unit at max incline, turn off power or press the emergency stop – clean and grease* incline motor screw        
As needed: with unit at max incline, clean and lubricate** the joints in the elevation rack – see figure 2        
Folding treadmills only – with the treadmill folded, clean and grease* the gas shock and support tube – see figure 3        

*Super Lube w PTFE grease is recommended to lubricate the incline motor screw
**Super Lube w PTFE spray is recommended to lubricate the elevation rack


Frame Bolts


From time to time, especially after a few uses when a product is new, you may see frame bolts starting to loosen. This can cause noise issues. This is natural and happens as the product settles to the floor and begins to be used. It is important after the first few uses, and then on a monthly basis, that you check the frame bolts. If you find loose bolts, it would be a good idea to add a medium-strength thread locker to the bolt threads before tightening. Once the thread locker cures, it will help prevent bolts from coming loose again. Cure times for thread locker is generally 24 hours so it is best to do this and not use the product during that time.

Tools needed for tightening bolts: metric Allen sockets (3mm-8mm) and ratcheting wrench


  1. Vibra-tite blue is a medium-strength thread locker that comes in a pump gel and is available at most hardware stores.
  2. Loctite blue is a medium-strength thread locker that comes in a squeeze bottle in liquid form and is available at most hardware stores.
