SPECIFIC OPERATING WARNINGS
1. Routinely inspect all accessory clips that join attachments to the cables and replace at the
first sign of wear.
2. Use only weight selector pins supplied by LIFE FITNESS on weight stacks. Substitutes are
forbidden.
3. Cables pose an extreme liability if used when frayed. Always replace any cable at first sign
of wear (consult LIFE FITNESS if uncertain).
4. Do not allow users to wear loose fitting clothing while using equipment. It is also
recommended to have users secure long hair back and up to avoid contact with moving
parts.
5. Fully insert weight selector pins. Partial insertion can cause weights to fall unexpectedly.
Never pin the weight stack in an elevated position. Never remove selector pin if any weights
are suspended. Never attempt to release jammed weights or parts.
6. When adjusting any seat, knee hold down pad, range of motion limiter, foothold pad or any
other type of adjuster, make certain that the adjusting pin is fully engaged in the hole to
avoid injury.
7. It is the purchaser’s sole responsibility to properly instruct its end users and supervising
personnel as to the proper operating procedures of all LIFE FITNESS equipment.
8. Keep children away from selectorized strength equipment. Parent or others supervising
children must provide close supervision of children if the equipment is used in the presence
of children.
9. Never use dumbbells or other means to incrementally increase the weight resistance. Use
only those means provided by LIFE FITNESS.
10. UNDERSTANDING EACH AND EVERY WARNING TO THE FULLEST IS IMPORTANT. IF
ANY OF THESE WARNINGS ARE UNCLEAR, ASK FOR CLARIFICATION FROM LIFE
FITNESS PERSONNEL.
11. Injuries may result if exercising improperly or excessively. It is recommended that all
individuals consult a physician prior to commencing an exercise program. If at any time
during exercise you feel faint, dizzy or experience pain, stop and consult your physician.
12. Do not exceed maximum user weight – 300 lbs.

1. Frame Construction
•Frame is constructed of mechanical quality steel purchased in mill run quantities
•Frame is primarily 2 ½” x 4 ½” and 1 5/8” x 2 ¾” oval-shaped tubing with 11 gauge
wall thickness.
•Core towers on jungles are fully welded (not bolt together) for maximum structural
integrity and minimum maintenance when possible. However, independent stations
have bolt-together configuration to facilitate movement through smaller doorways
and difficult installations
2. Frame Finish
•Prior to applying finish, each part is chemically washed to prepare surface for
maximum adhesion
•The frames are coated with an electrostatic epoxy powder coat finish applied in a
powder form and then baked at 400°F (204°C.)
•To prevent frame and surface corrosion, wax equipment annually and keep away
from salt, chlorine and all other harmful chemicals.
3. Weight Selection
•Weights are selected by using a 7/16” selector pin, which completely penetrates the
weight plate and is held in place during use by a magnetic ring to keep the pin from
disengaging chance of disengaging during use.
•The selector pin is connected to the top weight to eliminate loss of substitution of
substandard pins
4. Incremental Weights
•Incremental weights are provided for each station/weight stack. Material is solid steel
encased with a molded rubber that is formed to fit on the top-plate of the weight
stack.
5. Weight Plates
•Machined from solid, 1” thick steel. Finish is wrinkle gray powder coat. Thickness of
plate is held to precise tolerances by machining the entire upper and lower surfaces.
This results in a better pin fit to the stem.
6. Weight Plate Bushings
•Each plate (not just the top weight) will contain low friction bushings, which surround
the guide rods to minimize friction and noise

2. General Specifications LIFE FITNESS Cable Motion Owners Manual
2-2
7. Top Weight Bushings
•The top weight is stabilized with an engineered composite structure with self-
lubricating bushings.
8. Weight Stack Guide Rods
•Guide rods are ¾” cold drawn steel, turned ground and polished with hard chrome
finish
9. Weight Stack Suspension
•Durable rubber bumpers are placed under each stack to reduce shock and vibration
stresses to the frame and facility floor.
10.Weight Selection Shaft
•The shaft is constructed of zinc plated cold finished steel and precision drilled for
accurate pin selection
11. Weight Transport
•7x19 construction, 3/16” galvanized steel, internally lubricated, nylon-coated aircraft
cable with breaking strength rated at over 4,000 pounds.
12. Cable Adjustment
•All cables can be adjusted at the top weight utilizing a metric 24mm open-end
wrench.
13. Pulleys
•All pulleys are at least 4-1/4” working diameter using fiberglass-impregnated nylon
with precision fit cable groove and double sealed bearings.
14. Pulley Covers
•As a safety precaution, all pulleys are covered to minimize the danger of a moving
pulley catching a person’s finger or clothes.
15. Bolts
•All hardware is stainless steel, zinc or nickel plated
16. Upholstery
•Contoured pads on selective units
•All edges are stitched to eliminate any folds in the material that would limit durability.
17. Foam
•Three and Four pound EVA foam (deformation resistant) or equivalent is used on all
machines. The foam is injection molded directly to the multi-ply wood support board
with integral 10mm T-nuts.

grip to slide off the handle.
19. Foot Platforms
•All foot platforms are molded rubber with a slip resistant texture
20. Instructional Placard
•Visual placards provide visual illustration for proper use and muscles trained.
21. Equipment Anchoring

Chest Press (CMCP)
Muscles Exercised – Pectoralis Major, Anterior Deltoids and Triceps
Setup
Adjust the seat height so pulleys are aligned with mid-chest. Check the
weight stacks to ensure proper resistance. Grip the handles and position
elbows slightly below shoulders. Body is positioned with chest up, shoulders
and head back against the back pad.
Performing the Exercise
With a controlled motion, extend the handles out until the arms are fully
extended. Return the handles to the start position, without letting the
resistance rest on the stack. Repeat the motion while maintaining proper
body position.
TIP: While performing the exercise, choose varying incline and decline
p
ressing angles to maximize stimulation of the Pectoralis and Anterior Deltoid.

Shoulder Press (CMSP)
Muscles Exercised – Deltoids and Triceps
Setup
Adjust the seat height so handles are aligned with or above shoulder height. Check the
weight stacks to ensure appropriate resistance. Grip one or both handles. Body is
positioned with chest-up, shoulders and head back against back pad.
Performing the Exercise
With a controlled motion, extend the handles up until arms are fully extended. Return
the handles to the start position, without letting the resistance rest on the stack. Repeat
the motion, while maintaining proper body positioning.
TIP: Focus on extending your elbows as opposed to pressing the handles up,
as this increases the mental concentration on the Deltoid muscles.

Pulldown (CMPD)
3-7
Muscles Exercised – Latissimus Dorsi and Biceps
Setup:
Check the weight stacks to ensure appropriate resistance. Stand and grip handles, then
pull down and sit with thighs under pads. Upper body is positioned leaning slightly back
from the hips, pulling directly over shoulders.
TIP: Attempt to stabilize the body without the use of the thigh pads until necessary.
Performing the Exercise:
With a controlled motion, draw down the handles directly over the shoulders until hands
reach shoulder height, then extend the handles up until arms are fully extended. Return
the handles to the start position and repeat the motion, while maintaining proper body
positioning.
TIP: While performing the exercise think about lowering your elbows towards your
lower back. This will re-enforce the correct exercise position and increases the
mental concentration on the Latissimus Dorsi.

3. Exercise Section LIFE FITNESS Cable Motion Owners Manual
Row (CMRW)
Muscles Exercised – Latissimus Dorsi, Trapezius, Rhomboids, Teres Major
and Minor, Posterior Deltoids and Biceps
Setup
Check the weight stack to ensure appropriate resistance. Grip the handles and
position body with feet on the platform and head and chest-up.
Performing the Exercise
Stabilize the body in position, pressing feet firmly on foot platform. Stabilize
upper body by drawing in abdominals. With a controlled motion, draw back the
arms as far as can be controlled. Return the handles to the start position,
without letting the resistance rest on the stack. Repeat the motion, while
maintaining proper body positioning.
TIP: While performing the exercise, think about drawing the elbows back
beyond the body and stabilizing the upper body as this increases the mental
concentration on the muscles being trained.
