MAINTENANCE GUIDE 

General cleaning will help to prolong the life and improve the performance of your treadmill. Keep 
the unit clean and maintained by dusting the components on a regular basis. Cleaning the two 
exposed sides of the 

Running Belt (No. 13)

 will prevent dust from accumulating underneath. Keep 

your running shoes clean so that dirt from your shoes does not wear the 

Running Board (No. 10) 

and

 Running Belt (No. 13)

. Clean the surface of the 

Running Belt (No. 13)

 using a clean damp 

cloth. Keep liquids away from electrical parts and 

Running Belt (No. 13)

.
