Before You Begin

1Thank you for purchasing your Precor EFX Elliptical Fitness Crosstrainer. The EFX5.21s features a
zero impact, elliptical-shaped stride that lets you target specific lower-body muscles to achieve
better muscle tone and overall cardiovascular conditioning. The EFX is designed to use the
optional
Precor Heart Rate Interactive System featuring Smart Rate.TM
In addition to the standard display features, the Precor Heart Rate Interactive System offers an
easy-to-understand electronic console that gives motivating feedback about your workout and
incorporates the latest in cardiac monitoring to provide Smart RateTM— a visual aid that lets you
know where your heart rate is at a glance. When the Precor Heart Rate Option
receiver
is installed
and you wear the
chest strap
, the colored cells on the display light up to indicate your target zone.
You’ll be able to maintain your ideal training zone (weight loss or cardiovascular) by keeping the
blinking
cell within the target zone.
With Smart Rate you can see what your heart rate is doing when you use any of the four different
modes: Manual, Interval, Weight Loss, and Program. These courses provide variety to help
motivate you during your workout. In addition, the Heart Rate Control Course (HRC) monitors
your heart rate within a target zone (usually 55% to 90% of your maximum heart rate) and
automatically changes the resistance to keep your heart rate in that zone.
The EFX is designed for household use only and is unique in its crosstraining features. To
maximize your use of the EFX, please study this guide thoroughly.

Unpacking the EFX

The EFX is carefully tested and inspected before shipment. Precor ships the unit in three pieces:
base assembly
handrail assembly (includes the electronic console)
owner’s manual, limited warranty card, and parts — shown in Diagram 1
Allen wrench, power cord, and tie wrap.
Diagram 1
Carefully unpack the pieces of the EFX and lay them on the floor near the location where you plan
to use it.
Important: If you plan to move the EFX, do so
before
you install the handrails. Ask for assistance to
move the unit. Once the handrails are in place, the unit is wide enough that moving it down a
hallway or through a door frame (without scratching it) is very difficult.
After unpacking the EFX, pull out the plastic sack containing the items in Diagram 1. You will need
these items to complete the assembly of the EFX. If any items are missing, contact the dealer from
whom you purchased the EFX or call 1-800-4-PRECOR for the dealer nearest you.
CAUTION: This unit weighs over 160 pounds
(72 kilograms). To avoid injury and to ensure
the safety of the unit and yourself, get
adequate assistance before unpacking your
EFX. Slide the base assembly out of the box.
Power cord
1/4" Allen wrench
Tie wrap
