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

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.

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.

Setting Up the EFX

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.

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.
