2 Setting Up the EFX

Please read and follow the instructions in this manual. If you do not assemble and use the equipment according to the following information, you might void the Precor limited warranty.

Installation Requirements

CAUTION: Do not remove or otherwise bypass the 3-prong plug with an adapter or extension cord in order to use a non-grounded outlet.

Electrical damage can occur if the unit is connected to an improper power source.

•Fill out and mail the limited warranty card. The serial number is printed on a label located on the rear crossbar inside the rear casing. You will need a flashlight to read the label. Write the serial number onto the limited warranty card and in this manual before assembling the unit. Refer to Obtaining Service on page 24.

•Set up the EFX on a solid, level surface. If the unit is installed in a carpeted area, it is recommended that you place a piece of heavy cardboard, plywood, or other solid, flat, and level surface under the unit.

•Check that the Locking Pin is secure. A locking pin, inserted through the ramp and roller arm at the factory, provides an added security feature for the EFX. Before assembly, check that the locking pin is securely in place.

•Provide ample space around the machine. Open space around the machine allows for easier access to the I/0 (ON/OFF) switch and makes for a safer mount and dismount.

•Use a standard 120-volt household outlet. The EFX is for household use only. The EFX is equipped with an integral 3-prong, grounded plug that meets safety requirements and protects the machine.

CAUTION: If you plan to move the EFX, do so before you install the handrails. Ask for assistance to move the unit to its final location.

CAUTION: Do not cut the string that is secured to the base handrail support. The string is attached to the coiled ribbon cable.

Assembly Instructions

You should plan where you want to permanently locate the EFX because, once you install the handrails, the width of the EFX provides little room for maneuvering through a standard door frame and you could scratch or dent the unit.

To assemble the EFX, take the following steps.

Tools required: 1/4" Allen wrench (supplied) and scissors.

1.Locate the power switch at the rear of the unit. Make sure that the power switch is in the “0” position (OFF) and that the power cord is unplugged.

2.Remove the 4 curved washers and bolts from the handrail. Use the Allen wrench if necessary. Keep the washers on the bolts and set them within easy reach of the base handrail supports.
