Discovery Selectorized Line Owner's Manual: Important Safety Guidelines for Owners 1
Follow these guidelines to maintain proper working condition of the
equipment:
Important: Do not modify the equipment or any of its parts, or permanently remove
any part from the equipment. Do not use accessory attachments that are not
recommended by Precor, as such attachments might cause injuries.
Qualified technicians must perform all regular maintenance.
Check that all fasteners are securely tightened. Cables should be secured
at both end connections and properly threaded. Weight stacks should be
secure and functioning properly. Handle attachments should be properly
connected.
Make sure that trainers, facility personnel, and maintenance technicians
understand how to use the equipment, know important safety guidelines,
and can recognize potential problems such as a worn cable, loose
hardware, or cracked weld.
Strength training requires a significant focus by the facility and its staff to
maintain the quality of the fitness environment. If possible, the facility
should provide direct supervision of the fitness equipment at all times by
people knowledgeable about the safe operation of the equipment and
trained to recognize potential problems.
If any staff member witnesses unsafe use of the equipment, he or she
should address the user directly, demonstrate the proper technique, and
review the Important Safety Information for Users. Precor recommends posting
a copy of the Important Safety Information for Users near the equipment in a
prominent location.
Make sure the equipment is stable and placed on a solid surface. The
equipment is designed to be freestanding; however, it can be bolted to the
floor for extra stability. Precor highly recommends that the equipment be
bolted to the floor to reduce the risk of toppling the equipment due to
improper use. Since floor construction varies, please consult a professional
building engineer for proper fastening.
Locate the equipment at least 40 inches (1 meter) away from walls or
furniture on either side of the equipment, and 40 inches (1 meter) away
from objects behind the equipment. For Functional Training equipment,
make sure that the operating space is large enough to allow the cables to
be fully extended in all possible directions.
Check the equipment thoroughly based on the recommended inspection
schedules outlined in this manual, including daily, weekly, monthly and
annual checks. Ensure all bolt connections are tight and that the threaded
cables are properly and tightly secured at both ends.
Place an “out-of-order” sign on the equipment during maintenance of the
equipment or the surrounding area. Users should never be allowed to
operate the equipment until it has been inspected and works properly. If a
piece of equipment needs service, keep it out of use until it is repaired.
Place an “out-of-order” sign on the equipment and make sure the facility’s
personnel know not to allow anyone to use the equipment until it is
working properly.
When working with the weight stacks, do not attempt to free any jammed
assemblies without assistance as this may cause injury. With the help of
another person, carefully return the weight stack to the proper position
with the top plate resting on the first weight.
Do not allow the equipment to be used if the top plate or weight stack is
pinned in a raised position. With the help of another person, carefully
return the equipment to the proper position with the top plate resting on
the first weight. Inspect the cable to make sure that it is seated in all of the
pulleys.
Do not place the equipment outdoors or on wet surfaces.
Safety Approval
All Precor Discovery Selectorized strength equipment has been designed and
tested to EN957 and applicable ASTM standards.
Important Safety Guidelines for Owners
Discovery Selectorized Line Owner's Manual: Important Safety Information for Users 2
Before beginning any fitness program, you should obtain a complete physical
examination from your physician.
French equivalent of the preceding paragraph, for the Canadian market: Il est
conseillé de subir un examen médical complet avant d’entreprendre tout programme
d’exercise. Si vous avez des étourdissements ou des faiblesses, arrêtez les exercices
immédiatement.
When using exercise equipment, you should always take basic precautions,
including the following:
If you do not understand how to operate a piece of equipment, ask
someone from the facility such as a trainer to demonstrate how to use it
and explain any safety instructions.
Do not allow children on or near the equipment. Do not leave children
unsupervised around the equipment.
Use the equipment only for its intended purpose. Do not use accessory
attachments that are not recommended by the manufacturer, as such
attachments may cause injuries.
Wear proper exercise clothing and shoes for your workout—no loose
clothing.
Do not overexert yourself or work to exhaustion. Use reasonable
judgment when working with weights. Avoid using excessive weight,
which may cause injury.
If you feel pain, faintness, dizziness, or abnormal symptoms, stop
exercising immediately and consult your physician.
Keep head, limbs, fingers, and hair clear of all moving parts while the
equipment is in use. Keep hands clear of racking pegs.
Never drop or insert objects into any opening in the equipment.
Check that all fasteners are securely tightened. Cables should be secured
at both end connections and properly threaded. Weight stacks should be
secure and functioning properly. Handle attachments should be properly
connected.
Pay particular attention to the condition of cables and cable ends. If you
notice a loose cable end or any fraying of the cable or cable jacket, do not
use the product and contact someone in the facility immediately.
Always check the equipment before using it. If you spot a potential
problem, contact someone in the facility immediately. Do not use the
equipment until the facility has verified that the equipment is working
properly. Do not attempt to fix broken or jammed equipment.
Do not use the equipment outdoors or on wet surfaces.
Do not drop or slam the weight stack while exercising.
Be sure the selector pin is completely inserted. Use only the pin provided
by the manufacturer. If unsure, contact someone in the facility.
Never pin the weights in an elevated position. Do not use the equipment if
the top plate or weight stack is pinned in a raised position. Notify the
facility’s personnel to repair the equipment and ensure that it is working
properly.
Do not use the equipment if an "out of order" sign has been placed on it.
Read all posted instructions, including all safety instructions and warnings.

Rear Delt / Pec Fly User’s Guide
This dual equipment allows you to train both your chest and deltoid/upper
back muscles by varying your seated position. Functionally, these movements
complement each other; as your pectoral muscles contract, your upper back
and deltoid muscles lengthen to decelerate the movement. The opposite is
also true when the posterior muscles contract. Strengthening these muscles
groups will support upper body pushing and pulling strength, as well as
shoulder stabilization.

Rear Delt starting position Pec Fly starting position
Number Action
Select an appropriate weight.
Adjust range limiter for each arm to the start position shown.
Adjust the seat so the handles are at shoulder height.
