EFX 5.21/ 5.23 Elliptical Fitness Crosstrainer Assembly Guide 1
Thank you for choosing Precor. For proper installation, please read this guide
thoroughly and follow the assembly instructions. If you do not assemble the EFX
according to these guidelines, you could void the Precor Limited Warranty.
Obtaining Service
You should not attempt to service the EFX except for maintenance tasks
described in the owner’s manual. Should you need more information regarding
Customer Support numbers or a list of Precor authorized Service Centers, visit
the Precor web site at www.precor.com.
Unpacking the Equipment
The EFX is carefully tested and inspected before shipment. The unit is shipped in
one box. Ask for help to unpack and assemble the EFX. If any items are missing,
contact your dealer.
Important: (240 volt 5.23 model only) If the power cord attached to your
equipment is not compatible with your local power plug standards, the container
should also include a power cord for your region. You will need to install this
cord in place of the one attached to the equipment. If you need such a cord and
it was not included with your EFX, please contact your Precor dealer for the
correct Precor power cord. For a list of authorized Precor dealers in your area,
please contact Customer Support at www.Precor.com.
Required Tools
• Wire cutter
• Rubber mallet (EFX 5.23 only)
• Philips head screwdriver
Installation Requirements
Follow these installation requirements when assembling the unit:
•Assemble the EFX in the location where you plan to use it. No rollers or
wheels exist on the EFX, so it is not easy to move once it is fully
assembled.
•Provide ample space around the unit.
Important: Consult your owner’s manual for proper placement of your
equipment.
•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.
•Obtain assistance.
Ask another capable adult for assistance during the assembly process.
•Use your fingers or the appropriate tools to insert fasteners.
Proper alignment helps alleviate cross-threading. Do not fully tighten
fasteners until instructed to do so.
When fully tightened, the head of the fastener should be flush with the
product. If it is not, cross-threading has occurred. Do not attempt to rework
the assembly as more damage to the equipment will occur. Contact
Customer Support. Refer to Obtaining Service.

Assembly Steps
Important: Read the Installation Requirements before assembling
the EFX.
Ask your assistant to hold the right stabilizer, which has the cable
protruding from both ends, next to the base frame. Connect the
base cable. An audible click is heard when the cable is properly
attached. Place excess cable into the base frame.
Secure the stabilizer to the base frame using four hex head screws
(A) and four washers (B). Partially tighten.
Note: For easier access to the base mounts, lift the front of the
EFX off the floor and place a wedge of packing material beneath its
base.

Cut any wire ties that secure the cable to the stabilizer. Unwrap the
cable and remove any kinks. Feed the cable through the console
bracket as shown in the illustration.
Slide the console bracket into the right stabilizer and align the
three mounting holes. Insert the top two buttonhead screws (C)
with lock washers (D). Partially tighten.
CAUTION: Make sure you do not pinch the cables while attaching
the console bracket. Any damage caused during installation is
not covered by the Precor Limited Warranty.
Insert the bottom buttonhead screw (C) with lock washer (D).
Partially tighten.
Slide the left stabilizer onto the console bracket and secure its
base using four hex head screws (A) and four washers (B). Partially
tighten.
Note: You may need to pivot the stabilizer back and forth to fit it
snugly onto the console bracket.
Return to the console bracket and insert the three remaining
fasteners. Fully tighten all six console bracket fasteners.

Important: If your EFX is a 5.23 model, you will need to
attach the movable arms. If your EFX is a 5.21 model, please skip
steps 8-11.
Attach the right moving handlebar. Slide the handlebar pivot joint
onto the stabilizer axle (use a rubber mallet if needed).
Secure the handlebar using one buttonhead screw (E) and one
washer (F). Fully tighten. Snap the moveable arm cuff (M) into
place and then place a handlebar cap (L) onto the connection.
CAUTION: Guide the handlebar to its balance point and let it rest
there. When attaching the lower link arms, have your assistant
hold the moving handlebar for safety. Failure to do so could
result in injury.
Remove the locking pin so you can move the foot pedals to a
convenient location to attach the moving handlebars. Store the
locking pin in the hole underneath the ramp.
Attach the handlebar to the lower link arm using one buttonhead
screw (G), two washers (H), and one locknut (J). Fully tighten.
Repeat steps 8, 9, and 10 to secure the left handlebar.

Connect the 4-pin connector and the RJ45 to the appropriate
receptacles on the back of the display console. You will hear the
cable click into place when it is properly attached.
Place the excess cable into the console bracket.
Connect the green grounding wire to the middle receptacle
marked GND.
Attach the display console to the console bracket using three
Phillips-head screws (K). Tighten securely.
Return to the base of the stabilizers and fully tighten all eight hex
head screws.
Note: If necessary, remove the wedge of packing material used in
step 2.

Adjusting the Ramp
The EFX ramp incline can be set to one of three positions: Low (15
degrees), Medium (20 degrees), or High (25 degrees).
If you are on the equipment, dismount. To adjust the ramp, you can
straddle the equipment with one foot on either side or stand to one
side of it.
CAUTION: To adjust the ramp, you must be standing on the floor.
You cannot be standing on the equipment or the foot pedals.
Place one hand under the front of the ramp and one hand on the
lever. Pull the front of the ramp up and toward you while pulling the
lever back and up. This releases the ramp for adjustment.
Carefully adjust the ramp to the desired height.
Important: Before releasing your grip, test the ramp by gently
pushing it down with your hands to make sure that it has securely
clicked into one of the incline positions. The ramp should not move
when tested.
CAUTION: Be aware of the position of the handrails and console
when you are adjusting the ramp. Be careful not to bump your head
on the console when you stand up.

Before exercising, make sure the EFX is level and does not wobble from
side to side.
Important: If the EFX is placed on a slightly uneven surface, turning the
leveling pads can help, but will not compensate for extremely uneven
surfaces.
1. Kneel by the side of the stabilizer and lift the base slightly so you can
access the levelers.
2. Rotate the levelers as needed.
3. When the EFX is level, fully tighten the lock nut and lower the EFX to the
floor.
Connect the power cord.
CAUTION: Use the supplied and appropriate power cord. Do not remove
or otherwise bypass the 3-prong plug with an adapter in order to use a
non-grounded outlet. Do not plug the EFX into a power transformer in an
attempt to adjust the voltage requirements. Failure to follow these
instructions might damage the unit and will void the Precor Limited
Warranty. If an appropriate cord for your location was not included with
your EFX, please contact your Precor dealer for the proper Precor power
cord. For more information on authorized Precor dealers in your area,
please contact Customer Support at www.Precor.com.
1. Insert the power plug connector into its receptacle at the rear of the unit.
2. Plug the other end into a grounded outlet so you can maintain a
consistent power source without overloading any other circuitry. Be sure
to use the appropriate voltage. Refer to Grounding Instructions in the
owner’s manual.
Turn the unit On.
Use the power switch to turn the unit On. Check that the Precor banner
appears on the display. If the display remains blank, cycle the power. If the
display continues to remain blank, check the cable connections.
Important: Make sure the locking pin is removed and stored before you
begin exercising.
