Using the Stationary Handrail  
To maintain your balance, always grasp a stationary  
handrail when you step on or off the foot pedals, and when  
you use the keypad.  
Location  
It is important to keep a minimum distance of one foot (30  
cm) around the EFX open and free from obstacles such as  
other equipment.  
CAUTION: The EFX is not equipped with wheels and  
should be assembled in the location where you plan to  
use it. If you need to move the EFX, use the locking pin  
to secure the foot pedals, obtain help, and use proper  
lifting techniques.  
To learn more about the touch-sensitive grips on the EFX,  
refer to Heart Rate Features.  
Turning the Unit On and Off

Heart Rate Features  
Note: Handheld heart rate performance may vary based on  
a user’s physiology, fitness level, age, and other factors.  
You may experience an erratic readout if your hands are  
dry, dirty, or oily, or if the skin on your palms is especially  
thick. Wearing hand lotion can also cause an erratic  
readout.  
Important Safety Instructions  
Read the following before using the heart rate or  
SmartRate features.  
•
•
Consult your physician before engaging in any vigorous  
exercise. Do not use the heart rate programs until  
authorized by your physician.  
To use the handheld heart rate feature place the palm of  
your hands directly on the metal heart rate sensors on the  
unit’s handlebars. To ensure a more accurate heart rate  
readout, make sure you follow these tips.  
Know your heart rate and your physician-recommended  
heart rate target zone.  
Using the Touch-Sensitive Grips  
Note: While exercising, you must grasp both touch-  
sensitive grips for a minimum of five to ten seconds to  
transmit your heart rate to the display.  
•
It takes a number of consecutive heartbeats (15-20  
seconds) for your heart rate to register.  
•
When gripping the sensors, do not grip tightly. Keep a  
loose, cupping hold. Holding the grips tightly can make  
it difficult to read your heart rate.  
•
•
Make sure that the sensors are clean to ensure proper  
contact can be maintained.  
As you work out, your perspiration will help in  
transmitting your heart rate signal. If you are having  
difficulty using the handheld grips to determine your  
heart rate, try the sensors again later in your workout to  
see if you can get a heart rate signal.

Equipment Break-in Notice  
A thin protective sheath covers the roller arm wheels on  
your EFX. As you exercise, the roller arms move up and  
down the ramp and the wheels tend to squeak until the  
protective sheath wears off. Any noise from the wheels is  
normal and will stop after a break-in period. Please allow a  
break-in period of approximately ten hours before calling  
Customer Support.

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).  
1. If you are on the equipment, dismount and 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.  
2. 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.  
Diagram 8: Lift the front of the ramp as you lift the lever  
3. Carefully adjust the ramp to the desired height.  
Important: Before releasing your grip, test the ramp by  
gently moving it up and 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.

Choosing a Program  
Choosing a program depends on your goals. If you are a  
beginner or returning to regular exercise, you can start a  
cardio-conditioning program to slowly return your body to  
a comfortable level of exercise. If you have been exercising  
and feel that you have an intermediate or advanced fitness  
level, you probably have established goals. The Precor  
web site (www.precor.com) can give you many ideas about  
fitness workouts and advice from the experts.

The program sets the default target heart rate as 70%  
of 220 minus your age. Changing your stride rate or  
ramp incline affects the unit’s ability to maintain your  
target heart rate in the preferred zone. It takes time for  
the EFX to readjust the resistance so that your heart  
rate remains on target. Check the SmartRate and the  
HEART RATE displays to see if you are maintaining  
your preferred zone and to determine your actual heart  
rate. For information about understanding your target  
heart rate, refer to Heart Rate Features.  
Heart Rate Program Tips  
The Basic HRC Program enhances your overall  
cardiovascular fitness level to help you achieve your weight

Maintenance  
It is important to perform the minor maintenance tasks  
described in this section. Failure to maintain the EFX as  
described here could void the Precor Limited Warranty.  
Most of the working mechanisms are protected inside the  
covers. However, for efficient operation, the EFX relies on  
low friction. To keep the friction low, the unit’s ramp, foot  
pedals, handlebars, and covers must be as clean as  
possible.  
To reduce the risk of electrical shock,

power source before cleaning it or  
performing any maintenance tasks.  
Inspect the EFX before use.  
CAUTION: Do not use any acidic cleaners. Doing so will  
weaken the paint or powder coatings and void the  
Precor Limited Warranty. Never pour water or spray  
liquids on any part of the EFX. Allow the EFX to dry  
completely before using.  
Look and listen for slipping belts, loose fasteners, unusual  
noises, worn or frayed power cords, and any other  
indications that the equipment may be in need of service. If  
you notice any of these, obtain service.  
Important: If you determine that the EFX needs service,  
make sure that the EFX cannot be used inadvertently. Turn  
the unit Off, insert the locking pin and then unplug the  
power cord from its power source. Make sure other users  
know that the EFX needs service.  
Frequently vacuum the floor around the unit to prevent the  
accumulation of dust and dirt, which can affect the smooth  
operation of the unit. Use a soft nylon scrub brush to clean  
the foot pedals.  
To order parts or to contact a Precor authorized service  
provider in your area, refer to Obtaining Service.  
Long-Term Storage  
When the EFX is not in use for any length of time, turn it  
Off. Make sure that the power cord is unplugged from its  
power source and is positioned so that it will not become  
damaged or interfere with people or other equipment.

QUICKSTART™  
CAUTION: Before using the EFX, read all these  
instructions. Failure to do so may result in serious injury.  
Begin Your Workout with QUICKSTART  
To begin exercising immediately without personalizing your exercise  
session, take the following steps.  
• Do not allow children or those unfamiliar with its  
operation, on or near this equipment.  
• Before beginning any fitness program, see your  
physician for a thorough physical examination.  
Seek advice from your physician to learn the  
target heart rate appropriate for your  
fitness level.  
• Always face the display and use the  
stationary handrail for balance. Never  
attempt to turn around on the EFX.  
• If you feel pain, faintness, or dizziness,  
stop exercising immediately.  
1. Turn On the EFX using the power switch located at the rear of the  
unit, near the power cord.  
2. Remove the locking pin that secures the roller arm.  
3. Manually adjust the ramp to your preferred incline  
4. Hold on to the stationary handrail and step on the foot pedals.  
®
EFX 5.21  
5. Begin pedaling. Maintain a comfortable stride rate between 100  
and 150 strides per minute depending on your level of fitness.  
®
6. Press QUICKSTART and the Manual Program begins. An exercise  
session goal of 30 minutes appears in the TIME display and  
counts down.

locking pin after every workout.  
Workout Tips  
Pull firmly on the pin to slide it  
out of the roller arm. A lanyard  
attaches the locking pin to  
the ramp. Store the locking  
pin underneath the ramp  
once it is removed from  
the roller arm.  
• Before and after an exercise session, gently  
stretch your lower body and back to help prevent  
stiffness or soreness.  
8. Stop pedaling and hold on to the stationary handrail while you  
carefully step down from the EFX.  
9. To prevent unauthorized use, turn Off the EFX and secure the  
roller arm with the locking pin.  
• At the beginning of an exercise session, take  
several minutes to bring your heart rate into your  
target zone (shown in Diagram A on the other side  
of this card).  
• To display your heart rate, use both hands to grasp  
the touch-sensitive grips.  
•
To pause during your workout, stop pedaling. Pause  
mode has a 10-minute time limit.  
• Incorporate a cool-down period into your exercise  
session to help lower your heart rate and minimize  
muscle stiffness and soreness.

Choosing a Program  
SmartRate® Features  
Cooling Down After Your Workout  
•
Determine your level of fitness: beginner, intermediate,  
or advanced.  
When you begin an exercise session, a blinking segment  
in the SmartRate display appears if you entered your age  
during the setup phase. The blinking segment indicates  
the current zone of your heart rate.  
Cooling down is an important aspect of your workout  
because it helps reduce muscle stiffness and soreness  
by transporting excess lactic acid out of the working  
muscles. Cooling down for at least three minutes helps  
provide a smooth transition that allows your heart rate to  
return to its normal, non-exercising state.  
•
Determine your immediate goal: endurance training,  
cardio-conditioning, or weight loss.  
If you are a beginner, start a cardio-conditioning program  
to slowly adjust your body to a comfortable level of  
exercise. Over a recommended 8-week period, you will  
increase your endurance and strength while improving  
flexibility.  
The calculation used for the heart rate target zone is your  
maximum aerobic heart rate:  
(220 minus your age) multiplied by a percent.  
For the ideal weight loss range, your heart rate should  
remain between 55% and 70% of your maximum aerobic  
heart rate. To improve your overall cardio-vascular and  
respiratory fitness level, maintain your heart rate between  
70% and 87% of your maximum aerobic heart rate.  
Using a Chest Strap  
For all fitness levels, plan to exercise at a comfortable  
pace for 20 to 30 minutes a day. To monitor your heart  
rate, use the touch-sensitive grips. Supplement your plans  
with fitness workouts from the Precor web site  
(www.precor.com).  
Wearing a chest strap during your workout provides  
steady heart rate information. A chest strap is not  
included with this model.  
For the greatest benefits, maintain your heart rate in either  
zone for 30 minutes or more at least three times a week.  
Important: To receive an accurate reading, the strap  
needs to be in direct contact with the skin on the lower  
sternum (just below the bust line for women).  
CAUTION: Your heart rate should never exceed 87%  
of your maximum aerobic heart rate or go above  
your target zone (Diagram A).  
Monitoring Your Heart Rate  
To use a chest strap:  
The SmartRate and heart rate displays provide visual cues  
that help you adjust your fitness routine to reach your  
goals. Use these features to keep your heart rate within  
the target zones.  
1. Carefully dampen the back of the strap with tap water.  
Heart Rate Target Zones  
Important: Do not use deionized water. It does not  
have the proper minerals and salts to conduct  
electrical impulses.

180  
The EFX provides touch-sensitive heart rate grips on the  
handrails. If you wish to use the touch-sensitive grips and  
monitor your heart rate, use both hands. Make sure both  
hands are slightly moist (not dry) when you grasp the  
touch-sensitive grips.  
2. Adjust the strap and fasten it around your chest. The  
strap should feel snug, not restrictive.

3. Make sure that the chest strap is right-side-up, lies  
horizontally across, and is centered in the middle of  
your chest.  
Peak

4. Test the chest strap placement by checking the heart  
rate function on the equipment. If a heart rate is  
registering, your chest strap placement is correct. If  
the equipment does not register a heart rate, readjust  
the strap and recheck the heart rate function.

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.  
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.  
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.  
•
•
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.  
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.  
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.  
Required Tools  
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.

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.

Open the ferrite (N) and attach it near the ends of the cables,  
leaving enough space to attach both connectors.  
Note: Make sure the ferrite is securely closed around the cables.  
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 ferrite  
and 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.  
Connect the power cord.  
CAUTION: Use the supplied 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.  
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.  
1. Insert the power plug connector into its receptacle at the rear of the unit.  
2. Rotate the levelers as needed.  
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.  
3. When the EFX is level, fully tighten the lock nut and lower the EFX to the  
floor.  
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.
