Is there a weight limit for the treadmill?

Yes, only persons weighing 250 lbs. or less should use the treadmill. Some models of treadmills accommodate up to 300 lbs. Check your Owner's manual for the specific weight limit.

What causes the belt to slow down when walking on it?

A lack of belt lubricant on the walking belt is a common cause. Follow the information in your Owner's manual for the proper type of belt lubricate and instruction for lubricating the walking belt.

 

A worn platform, walking belt or an overtightened walking belt will also cause the belt to slow down when walking.

What causes the belt to slip when walking on it?

A loose walking belt will cause the belt to loose grip of the front roller and cause the walking belt to slip. Unplug the treadmill and remove the key before adjusting the belt tension. Tighten the walking belt using the adjustment screws at the back of the foot rails. To tighten the belt, use the Allen wrench supplied with the treadmill. Turn both screws clockwise 1/4 of a turn to tighten the walking belt. When correctly tightened, you should be able to lift each edge of the walking belt 2-3 inches off the walking platform. Do not over tighten the walking belt.

Why is the walking belt off-center?

To center the walking belt, unplug the treadmill and remove the key. Use the Allen wrench supplied with the treadmill to adjust and center the walking belt. Use the two adjustment screws at the back of the foot rails. If the walking belt has shifted to the left, turn the left adjustment screw clockwise 1/2 of a turn. If the walking belt has shifted to the right, turn the left adjustment screw counter-clockwise 1/2 of a turn. 

Why won't my treadmill turn on?

First, check and confirm the wall outlet has power. Plug some other working electrical appliance in the outlet to check the outlet for power.

 

Check to see if the power switch where the power cord enters the treadmill has tripped off. Flip the power switch to ON to reset the power switch.

What would cause my treadmill to power off during use?

Check the wall outlet for power. Check the surge protector and the power cord for a loose power cord connection. Check the treadmills power switch to see if has tripped. If tripped, wait 5 minutes and then press the switch back. Remove the key from the console and then reinsert it.

Do I have to plug the treadmill into a surge protector?

Failure to plug the treadmill into a surge protector could result in damage to the electronic controls. Use a surge protector to reduce the risk of damage to the electronic controls. A damaged control system may cause the walking belt to slow down, speed up or stop unexpectedly.

 

Use only a surge protector that meets all of the specifications described in the user's manual.
