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.

Workout Tips
•Before and after an exercise session, gently
stretch your lower body and back to help prevent
stiffness or soreness.
•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
•Determine your level of fitness: beginner, intermediate,
or advanced.
•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.
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).
Using the Touch Heart Rate Feature
Note: Touch 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. In
addition, make sure that the sensors are clean to ensure
proper contact can be maintained.
To use the touch heart rate feature, place the palm of your
hands directly on the metal heart rate sensors on the
equipment’s handlebars. To ensure a more accurate heart
rate readout, make sure you follow these tips:
•Both hands must grip the sensors for your heart rate to
register.
•It takes a number of consecutive heart beats
(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
affect the reading.
•As you work out, your perspiration will help transmit
your heart rate signal. If you have difficulty using the
handheld grips to determine your heart rate, try the
sensors again later in the workout to see if you can
obtain a heart rate signal.
•If the touch heart rate feature does not work for you,
Precor recommends that you use a chest transmitter
strap.
CAUTION: Your heart rate should never exceed 85%
of your maximum aerobic heart rate. Your
maximum heart rate is equal to 220 minus your age.
(Diagram A).
Diagram A
Using a Chest Strap Transmitter
Signals used by the Chest Strap
Transmitter (or heart rate strap)
may interfere with pacemakers or
other implanted devices. Consult
your physician and the
manufacturers of your Chest Strap
Transmitter and implanted device
before using a Chest Strap
Transmitter.
Wearing a chest strap transmitter during your workout
provides steady heart rate information. For the equipment
to detect your heart rate, you must grip the touch heart
rate sensors or wear a chest strap transmitter while
exercising. In the presence of both touch and wireless
data, the touch data takes precedence and will display.
Note:
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).
To use a chest strap:
1. Carefully dampen the back of the strap with tap water.
Important: Do not use deionized water. It does not
have the proper minerals and salts to conduct
electrical impulses.
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.
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.
