ProForm 397 user manual Symptom The walking belt slows when walked on

Locate the Reed Switch (33) and the Magnet (32) on the right side of the Pulley (31). 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 in. (3 mm). If necessary, loosen the #8 x 3/4" Truss Head Screw (14), move the Reed Switch slightly, and then retighten the Screw. Carefully slide the Motor Hood (not shown) back on by lining up the guides. Reattach the Motor Hood with the five #8 x 3/4" Screws (not shown). Then, plug in the power cord, insert the key, and run the treadmill for a few min- utes to check for a correct speed reading.

SYMPTOM: The incline of the treadmill does not change correctly

a.Hold down the Stop button and the Speed increase button, insert the key into the console, and then release the Stop button and the Speed increase button. Press the Stop button and then press the Incline increase or decrease button. The treadmill will automatically rise to the maximum incline level and then return to the minimum level. This will re- calibrate the incline system. If the incline does not begin calibrating, press the Stop button again, and then press the Incline increase or decrease button again. When the incline is calibrated, remove the key from the console.

SYMPTOM: The walking belt slows when walked on

a.Use only a single-outlet surge suppressor that meets all of the specifications described on page 13.

b.If the walking belt is overtightened, treadmill per- formance may decrease and the walking belt may become damaged. Remove the key and UNPLUG THE POWER CORD. Using the hex key, turn both idler roller screws counterclockwise, 1/4 of a turn. When the walking belt is properly tightened, you should be able to lift each edge of the walking belt 2 to 3 in. (5 to 7 cm) off the walking platform. Be careful to keep the walking belt centered. Then, plug in the power cord, insert the key, and run the treadmill for a few minutes. Repeat until the walk- ing belt is properly tightened.

c.Your treadmill features a walking belt coated with high-performance lubricant. IMPORTANT: Never apply silicone spray or other substances to the walking belt or the walking platform unless in- structed to do so by an authorized service rep- resentative. Such substances may deteriorate the walking belt and cause excessive wear. If you suspect that the walking belt needs more lubri- cant, see the front cover of this manual.

d.If the walking belt still slows when walked on, see the front cover of this manual.
