Page 5 Grounding Instructions This product must be grounded. If it should malfunction or break down, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This product is equipped with a cord having an equipment-grounding conductor and a grounding plug.
Page 6 Storage and Moving the Machine The machine can be moved by one or more persons. Use caution when you move the machine. The treadmill is heavy and can be awkward. Make sure that your own physical strength is capable of moving the machine.
Page 7 Do not use the Console, handlebars, or lifted walking deck to lift or move the treadmill. Damage to the treadmill can occur. Keep clear of the movement path of the lifted walking deck. Roll the machine on the transport wheels (5c) to its new location. Do not put objects where the walking deck would be if lowered.
Page 8 Leveling the Machine The machine needs to be leveled if your workout area is uneven. To adjust: Place the machine in your workout area. Adjust the levelers until they all contact the floor. Do not adjust the levelers to such a height that they detach or unscrew from the machine. Injury to you or damage to the machine can occur.

Page 11 Adjusting the Belt Tension If the walking belt starts to slip during use, it is necessary to adjust the tension. Your treadmill has tension bolts at the rear of the treadmill. Make sure that the walking belt is stopped and the power switch is turned Off. Be sure not to touch the moving walking belt or step on the power cord.
Page 12 If the belt moves to the right, turn the left adjustment bolt 1/4 turn counterclockwise and the right adjustment bolt 1/4 turn clockwise. Monitor the path of the belt for approximately 2 minutes. Continue to adjust the bolts until the walking belt is centered.
