Chapter 2
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 the EFX 821 Elliptical Fitness Crosstrainer
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
Follow these installation requirements when assembling the
unit:
Assemble the unit near the location where you plan to
use it.
Provide ample space around the unit.
Open space around the unit allows for easier access.
Set up the unit on a solid, flat surface.
A smooth, flat surface under the unit helps keep it level. A
level unit has fewer malfunctions.
Open the box and assemble the components in the
sequence presented in this guide.
The unit is shipped in one box. Ask for help from two or
more people to unpack and assemble the Climber.
Insert all fasteners with your fingers.
Use your fingers to properly align and thread the
fasteners. This helps alleviate cross-threading. Do not
fully wrench tighten fasteners until instructed to do so.
Important: When wrench tightening, the head of the fastener
should be flush with the product. If it is not, cross-threading
may have occurred. Do not attempt to rework the assembly as
more damage to the equipment will occur. Contact Customer
Support. Refer to Obtaining Service.
If you plan to move the unit, obtain help and use a hand
truck.
Do not grasp any plastic parts while lifting or moving the
unit. The plastic parts are not capable of supporting the
weight of the unit and they may break.
