request of the customer)
Cleaning
Please make sure the treadmill's power plug is pulled out before cleaning or maintaining the product.
Keep treadmill clean by dusting regularly. Be sure to clean the exposed part on both sides of the running belt , which can reduce the piling of dust
under the running belt. Make sure the shoes are clean , avoid to take foreign material to under the running belt to wear off the running belt and
running board. The top of the belt need to be cleaned with a wet, soapy cloth. Be careful to keep liquid away from the electrical components and
underneath the running belt.
WARNING
Remember to unplug the treadmill from the electrical outlet before removing the motor cover. Remove the motor cover and vacuum under the
motor cover at least once a year.
