Before You Begin

Thank you for purchasing your Precor EFX Elliptical Fitness Crosstrainer. The EFX5.21si 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 RateTM.

 

The EFX offers an easy-to-understand display 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 POLAR® chest strap, the colored cells on the display light up

 

to indicate your target zone. You’ll be able to maintain your ideal zone (weight loss or cardiovascu-

 

lar) by keeping the blinking cell within the target zone.

 

With Smart RateTM, you can “see” your pulse in any course: Manual (MANL), CrossTrainer (XTR),

 

Gluteals (GLT), Interval (INTV), Weight Loss (WTLS), Random (RAND) and Custom (CST1 & CST2).

 

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 85% 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 display console)

 

•

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.

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.
