Before You Begin Thank you for purchasing the easy-to-use electronic console option for your Precor 903 Manual or 904 Total Body Treadmill. Before assembling the console onto your treadmill, take the time to read through this manual so that you are familiar with the contents of the package and the features on the electronic console. Obtain the appropriate tools before assembling the electronic console onto the 903 or 904 treadmill.
Installing the Electronic Console The handrail clamp can be used on either the 903 or 904 treadmill. However, the steps used to install the console onto the clamp are slightly different depending on which treadmill you have. Please refer to the steps that apply to your treadmill. 903 Assembly Procedures To install the 903 electronic console, take the following steps: 1. Locate the handrail clamp in the box that accompanies the electronic console’s box.
Diagram 2 3. Unlock and remove the mounting bracket from the back of the electronic console. Unlock the mounting bracket by pushing it down toward the base of the console. See Diagram 2. 4. Position the mounting bracket onto the handrail clamp so that the smooth side of the plate is facing you. See Diagram 3.
5. Secure the mounting bracket and clamp by inserting the two long screws through the mounting holes. You may need to squeeze the ends of the clamp together to install the screws. See Diagram 3. Tighten the screws into the recessed holes on the mounting plate using the Phillips head screwdriver. Do not over tighten the screws. A gap should remain between the opposite sides of the handrail clamp. 6. Unwrap the reed switch wire. Route the connector and wire through the hole in the handrail clamp.
