ProForm PFTL721040 user manual Problem The walking belt slows when walked on, Top

With the help of a second person, carefully raise the Uprights (97) to the position shown. Carefully pivot the Hood (105) off.

Locate the Reed Switch (22) and the Magnet (19) on the left side of the Pulley (18). Turn the Pulley until the Magnet is aligned with the Reed Switch. Make sure that the gap between the Magnet and the Reed Switch is about 1/8”. If necessary, loosen the Screw (23), move the Reed Switch slightly, and then retighten the Screw. Reattach the Hood, and run the treadmill for a few minutes to check for a correct speed reading.

SOLUTION: a. Use only a single-outlet surge suppressor that meets all of the specifications described on page 9.

b. If the walking belt is overtightened, treadmill perfor- mance may decrease and the walking belt may be- come damaged. Remove the key and UNPLUG THE POWER CORD. Using the allen wrench, turn both rear roller adjustment bolts counterclockwise, 1/4 of a turn. When the walking belt is properly tightened, you should be able to lift each side of the walking belt 2 to 3 inches off the walking platform. Be careful to keep the walking belt centered. Plug in the power cord, in- sert the key, and run the treadmill for a few minutes. Repeat until the walking belt is properly tightened.

Be careful not to overtighten the walking belt. Plug in the power cord, insert the key, and run the treadmill for a few minutes. Repeat until the walking belt is centered.

b. If the walking belt slips when walked on, first re- move the key and UNPLUG THE POWER CORD. Using the allen wrench, turn both rear roller bolts clockwise, 1/4 of a turn. When the walking belt is cor- rectly tightened, you should be able to lift each side of the walking belt 2 to 3 inches off the walking platform. Be careful to keep the walking belt centered. Plug in the power cord, insert the key, and carefully walk on the treadmill for a few minutes. Repeat until the walk- ing belt is properly tightened.
