Hazardous Materials and Proper Disposal
The batteries within self-powered equipment contain
materials that are considered hazardous to the environment.
Federal law requires proper disposal of these batteries.
If you plan to dispose of your equipment, contact Precor
Commercial Products Customer Support for information
regarding battery removal. Refer to Obtaining Service.
Product Recycling and Disposal
This equipment must be recycled or discarded according to
applicable local and national regulations.
Product labels, in accordance with European Directive
2002/96/EC concerning waste electrical and electronic
equipment (WEEE), determine the framework for the return
and recycling of used equipment as applicable throughout the
European Union. The WEEE label indicates that the product is
not to be thrown away, but rather reclaimed upon end of life
per this Directive.
In accordance with the European WEEE Directive, electrical
and electronic equipment (EEE) is to be collected separately
and to be reused, recycled, or recovered at end of life. Users
of EEE with the WEEE label per Annex IV of the WEEE
Directive must not dispose of end of life EEE as unsorted
municipal waste, but use the collection framework available
to customers for the return, recycling, and recovery of WEEE.
Customer participation is important to minimize any potential
effects of EEE on the environment and human health due to
the potential presence of hazardous substances in EEE. For
proper collection and treatment, refer to Obtaining Service.

Electrical Recommendations: All Equipment
Excluding Treadmills
Note: This is a recommendation only. NEC (National Electric
Code) guidelines or local region electric codes must be
followed.
For equipment fitted with a P80 console or Personal Viewing
System (PVS) screen a separate power connection is
required. For a 20 amp branch circuit up to 10 screens can be
connected. If the branch circuit has any other devices plugged
into the circuit the number of screens must be reduced by the
wattage of the other devices.
Note: The typical splitter power cords that have IEC-320 C13
and C14 plugs have a recommended maximum capacity of
five screens.

Chapter 1
Assembling the EFX
WARNING You will need the assistance of two other people to assemble
this unit. DO NOT attempt assembly by yourself.
Important: The instructions in the following procedures are
described from the perspective of a person standing directly in
front of the equipment (that is, on the opposite side of the
control console from a person using the equipment). These
descriptions may not match the names of certain parts in the parts
list, because such parts are named relative to the back of the
equipment.
To prepare the EFX for assembly:
Open the box and assemble the components in the
sequence presented in this guide.
Assemble and operate your equipment on a hard, level
surface in the area intended for use.
Use a hand truck or furniture dolly to move the EFX unit.
Important:Do not grasp the unit by any of its plastic parts to
move it. The plastic parts are non-structural covers and are
not capable of supporting the weight of the unit.
Provide ample space around the unit.
Assemble the equipment according to the guidelines in
this manual to ensure that you do not void the Precor
Limited Warranty.
Important: Any damage caused during installation is not
covered by the Precor Limited Warranty.

14 Assembling and Maintaining Elliptical Fitness Crosstrainers: EFX 885 / 835
Begin installation of all fasteners by hand, then partially
tighten them. Do not fully tighten fasteners until
instructed to do so.
Important:When wrench-tightening the screws, make sure
the head of the fastener is parallel to the product surface. If it
is not, stop tightening to avoid cross-threading. To avoid
further damage, stop assembly work and contact Customer
Support.
Installation Requirements
Prior to assembly, make sure you have the required tools and
hardware.
Hardware Kit (not to scale)

DANGER
Do not attempt to connect electrical power until all
assembly procedures are complete and the console
is properly installed.
As you assemble the EFX, make sure to construct the cable
assembly as directed so that the necessary connections are
accessible when you add the console.
To begin assembly:
1. Remove the lift cover and set it aside.
Important:Grease on the lift screw can stain clothing. Be
careful not to get grease on your clothing as you remove the
lift cover. Do not remove the grease from the lift screw,
because it is required for proper operation.
Figure 2: Lift cover removal
2. Thread the cable through the left upright support. Tape it
to the top of the upright support to secure it temporarily.

Assembling the EFX 17
Important: Do not stretch, crimp, or damage the cable.
Cables damaged by improper installation will not be covered
by the Precor Limited Warranty.
Figure 3: Thread cable through upright support
3. Attach the left upright support to the base frame using
four buttonhead screws, four split washers, and four
⁵₁₆-inch washers. Partially tighten the fasteners.
Figure 4: Attach the upright support to the base frame
4. Repeat steps 2 through 4 to attach the right upright
support.

18 Assembling and Maintaining Elliptical Fitness Crosstrainers: EFX 885 / 835
5. Using a right-angle ³₁₆" hex wrench, remove the four ¹₄" x
³₄" buttonhead screws securing the central plastic base
cover.
6. Remove the tape at the top of the left upright support.
7. Feed one of the cables you want to install down through
the upright support, then along the inside of the foot
support and back through the central frame member. The
following illustration shows the general path of the cable.
Figure 5: EFX cable path
8. Pull the end of the cable upward through the opening just
behind the lift motor, as shown in the previous illustration.
