ASSEMBLY

The assembly requires two people. Set the treadmill in a cleared area and remove all packing materials. Do not dispose of the packing materials until assembly is completed. Assembly requires the included Allen wrench1 and your own Phillips screwdriver 3and rubber mallet2.

Note: The underside of the treadmill walking belt is coated with high-performance lubricant. During shipping, a small amount of lubricant may be transferred to the top of the walking belt or the shipping carton. This is a normal condition and does not affect treadmill performance. If there is lubricant on top of the walking belt, simply wipe off the lubricant with a soft cloth and a mild, non-abrasive cleaner.

OPERATION AND ADJUSTMENT

THE PERFORMANT LUBETM WALKING BELT

Your treadmill features a walking belt coated with PERFORMANT LUBETM, a high-performance lubricant. IMPORTANT: Never apply silicone spray or other substances to the walking belt or the walking platform. Such substances will deteriorate the walking belt and cause excessive wear.

HOW TO PLUG IN THE POWER CORD

Your treadmill, like any other type of sophisticated electronic equipment, can be seriously damaged by sudden voltage changes in your home’s power. Voltage surges, spikes, and noise interference can result from weather conditions or from other appliances being turned on or off. To decrease the possibility of your treadmill being damaged, always use a surge suppressor with your treadmill (see drawing 1 at the right).

To purchase a surge suppressor, see your local SEARS dealer or call toll-free 1-800-366-7278 and order part number 146148. Use only a single-outlet surge suppressor that is UL 1449 listed as a transient voltage surge suppressor (TVSS). The surge suppressor must have a UL suppressed voltage rating of 400 volts or less and a minimum surge dissipation of 450 joules. The surge suppressor must be electrically rated for 120 volts AC and 15 amps.

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. Plug the power cord into a surge suppressor, and plug the surge suppressor into an appropriate outlet that is properly installed and grounded in accordance with all local codes and ordinances.

Important: The treadmill is not compatible with GFCI-equipped outlets. This product is for use on a nominal 120-volt circuit and has a grounding plug that looks like the plug illustrated in drawing 1 below. A temporary adapter that looks like the adapter illustrated in drawing 2 may be used to connect the surge suppressor to a 2-pole receptacle, as shown in drawing 2, if a properly grounded outlet is not available.ProForm 635CW Treadmill User Manual 8

The temporary adapter should be used only until a properly grounded outlet (drawing 1) can be installed by a qualified electrician. The green-colored rigid ear, lug, or the like extending from the adapter must be connected to a permanent ground, such as a properly grounded outlet box cover. Whenever the adapter is used, it must be held in place by a metal screw. Some 2-pole receptacle outlet box covers are not grounded. Contact a qualified electrician to determine if the outlet box cover is grounded before using an adapter.

TROUBLE-SHOOTING

Most treadmill problems can be solved by following the simple steps below. Find the symptom that applies, and follow the steps listed. If further assistance is needed, call our toll-free HELPLINE at 1-800-736-6879, Monday through Saturday, 7 a.m. until 7 p.m. Central Time (excluding holidays).

1. SYMPTOM: THE POWER DOES NOT TURN ON

  • Make sure that the power cord is plugged into a surge suppressor, and that the surge suppressor is plugged into a properly grounded outlet (see page 8). Use only a single-outlet surge suppressor that is UL 1449 listed as a transient voltage surge suppressor (TVSS). The surge suppressor must have a UL suppressed voltage rating of 400 volts or less and a minimum surge dissipation of 450 joules. The surge suppressor must be electrically rated for 120 volts AC and 15 amps. Important: The treadmill is not compatible with GFCI-equipped outlets.
  • After the power cord has been plugged in, make sure that the key is fully inserted into the console.
  • Check the circuit breaker located on the treadmill near the power cord. If the switch protrudes as shown, the
  • The circuit breaker has tripped. To reset the circuit breaker, wait for five minutes and then press the switch back in.
  • Check the on/off switch located on the treadmill near the power cord. The switch must be in the on position.ProForm 635CW Treadmill User Manual 21

2. SYMPTOM: THE POWER TURNS OFF DURING USE

  • Check the circuit breaker located on the treadmill frame near the power cord (see 1.c. above). If the circuit breaker has tripped, wait for five minutes and then press the switch back in.
  • Make sure that the power cord is plugged in.
  • Remove the key from the console. Reinsert the key fully into the console.
  • Make sure that the on/off switch is in the on position.
  • If the treadmill still will not run, please call our toll-free HELPLINE.

3. SYMPTOM: THE DISPLAYS OF THE CONSOLE DO NOT FUNCTION PROPERLY

  • Remove the key from the console and unplug the power cord. Remove the screws from the hood and carefully remove the hood. Locate the Reed Switch (21) and the Magnet (43) on the left side of the Pulley (42). 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 Reed Switch Screw (76) and move the Reed Switch slightly. Retighten the Screw. Re-attach the hood, and run the treadmill for a few minutes to check for a correct speed reading.ProForm 635CW Treadmill User Manual 22

4. SYMPTOM: THE INCLINE OF THE TREADMILL DOES NOT CHANGE CORRECTLY OR DOES NOT CHANGE WHEN IFIT.COM CDs AND VIDEOS ARE PLAYED

  • With the key inserted in the console, press one of the incline buttons. While the incline is changing, remove the key. After a few seconds, re-insert the key. The treadmill will automatically rise to the maximum incline level and then return to the minimum level. This will recalibrate the incline.

5. SYMPTOM: THE WALKING BELT SLOWS WHEN WALKED ON

  • Use only a UL-listed surge suppressor, rated at 15 amps, with a 14-gauge cord of five feet or less in length.
  • If the walking belt is overtightened, treadmill performance may decrease, and the walking belt may be permanently 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 3 to 4 inches off the walking platform. The center of the walking belt should just touch the walking platform. Be careful to keep the walking belt centered. Plug in the power cord, insert the key, and run the treadmill for a few minutes. Repeat until the walking belt is properly tightened.ProForm 635CW Treadmill User Manual 23
