GROUNDING INSTRUCTIONS
This product must be grounded. If a treadmill should malfunction or breakdown, grounding provides a path of least resistance
for electrical current to reduce the risk of electrical shock. This product is equipped with a cord having an equipment-grounding
conductor and a grounding plug. The plug must be plugged into an appropriate outlet that is properly installed and grounded in
accordance with local codes and ordinances.
Connect this exercise product to a properly grounded outlet only.
Never operate product with a damaged cord or plug even if it is working
properly. Never operate any product if it appears damaged, or has been
immersed in water. Contact Customer Tech Support for replacement or repair.

WARNING
DANGER
Improper connection of the equipment-grounding conductor can result in a risk of electric shock. Check with a qualified
electrician or serviceman if you are in doubt as to whether the product is properly grounded. Do not modify the plug provided
with the product. If it will not fit the outlet, have a proper outlet installed by a qualified electrician.
This product is for use on a nominal 110-120 Volt circuit and has a grounding plug that looks like the plug in the illustration. Make
sure that the product is connected to an outlet having the same configuration as the plug. No adapter should be used with this
product.
This product must be used on a dedicated circuit. To determine if you are on a dedicated circuit, shut off the power to that circuit
and observe if any other devices lose power. If so, move devices to a different circuit. Note: There are usually multiple outlets on one
circuit. This treadmill should be used with a minimum 15-amp circuit.

ASSEMBLY
There are several areas during the assembly process that special attention must be paid. It is very important to follow the assembly
instructions correctly and to make sure all parts are firmly tightened. If the assembly instructions are not followed correctly, the
treadmill could have parts that are not tightened and will seem loose and may cause irritating noises. To prevent damage to the
treadmill, the assembly instructions must be reviewed and corrective actions should be taken.
Before proceeding, find your treadmill’s serial number located on a white barcode sticker
on the base frame as shown in this image.
