ASSEMBLY
• As you assemble the weight system, make sure
all parts are oriented as shown in the drawings.
Make Things Easier for Yourself
Everything in this manual is designed to ensure
that the weight system can be assembled suc-
cessfully by anyone. However, it is important to
realize that the versatile weight system has
many parts and that the assembly process will
take time. Most people find that by setting aside
plenty of time, assembly will go smoothly.
• For help identifying small parts, use the PART
IDENTIFICATION CHART.
The following tools (not included) are required
for assembly:
• two adjustable wrenches
• one rubber mallet
Before beginning assembly, carefully read the
following information and instructions:
• one standard screwdriver
• one Phillips screwdriver
• Assembly requires two people.
• lubricant, such as grease or petroleum jelly,
and soapy water.
• Place all parts in a cleared area and remove the
packing materials. Do not dispose of the packing
materials until assembly is completed.
Assembly will be more convenient if you have a
socket set, a set of open-end or closed-end
wrenches, or a set of ratchet wrenches.
• Tighten all parts as you assemble them, unless
instructed to do otherwise.

33. Make sure that all parts have been properly tightened. The use of all remaining parts will be explained in
ADJUSTMENTS, below.
Before using the weight system, pull each cable a few times to make sure that the cables move smoothly
over the pulleys. If one of the cables does not move smoothly, find and correct the problem. IMPORTANT: If
the cables are not properly routed, they may be damaged when heavy weight is used. See the CABLE
DIAGRAM on page 17 of this manual for proper cable routing. If there is any slack in the cables, you
will need to remove it by tightening the cables; see TIGHTENING THE CABLES on page 15.
ADJUSTMENTS
This section explains how to adjust the weight system. See the EXERCISE GUIDELINES on page 18 for impor-
tant information about how to get the most benefit from your exercise program. Also, refer to the accompanying
exercise guide to see the correct form for each exercise.
Make sure all parts are properly tightened each time the weight system is used. Replace any worn parts immediate-
ly. The weight system can be cleaned with a damp cloth and a mild, non-abrasive detergent. Do not use solvents.
ATTACHING THE ACCESSORIES TO A PULLEY
STATION
Attach the Lat Bar (42) to the High Cable (45) with a
Cable Clip (52). For some exercises, the Chain (not
shown) should be attached between the Lat Bar and
45
the High Cable with two Cable Clips. Adjust the
length of the Chain between the Lat Bar and the
Short Cable so the Lat Bar is in the correct start-
ing position for the exercise to be performed.

ADDING WEIGHTS TO THE WEIGHT CARRIAGE
To add resistance to the weight system, slide an equal
amount of weight (not included) onto each side of the
weight tube on the Weight Carriage (14). Be sure that
the weights are pushed against the weight stops. Note:
Due to the cables and pulleys, the actual amount of
resistance at each exercise station may vary from
the amount of weight used. Use the WEIGHT
RESISTANCE CHART on page 16 to find the

approximate amount of resistance at each station.
If Olympic weights are to be used, slide the two
Weight Adapters (20) onto the weight tube on the
Weight Carriage (14).
14
WARNING: Do not place more
than 125 pounds on the Weight Carriage (14).
TIGHTENING THE CABLES
Woven cable, the type of cable used on the weight
system, can stretch slightly when it is first used. If
there is slack in the cables before resistance is felt,
the cables should be tightened.
71
38
36
Slack can be removed by moving a 90mm Pulley (38)
and Cable Trap (44) to a set of holes closer to the
center of the two Pulley Plates (36). Remove the M10
Nylon Locknut (71) and the M10 x 47mm Bolt (61)
from the Cable Trap, the Pulley, and the Pulley
Plates. Re-attach the Pulley and the Cable Trap to
the new set of holes in the Pulley Plates with the Bolt
and Nylon Locknut. Make sure that the Cable Trap
is in the proper position and that the Cable and
Pulley move smoothly.

CABLE DIAGRAMS
The cable diagrams below show the proper routing of the Butterfly Cable (46), the High Cable (45), and the Low
Cable (47). Use the diagrams to make sure that the cables and the cable traps have been assembled correctly.
If the cables have not been correctly routed, the weight system will not function properly and damage may occur.
The numbers show the correct route for each cable. Make sure that the cable traps do not touch or bind the
cables.

EXERCISE GUIDELINES
THE FOUR BASIC TYPES OF WORKOUTS
PERSONALIZING YOUR EXERCISE PROGRAM
Muscle Building
To increase the size and strength of your muscles,

sively increase the intensity of your exercise. You can
adjust the intensity level of an individual exercise in
two ways:
• by changing the amount of weight used
• by changing the number of repetitions or sets per-
formed. (A “repetition” is one complete cycle of an
exercise, such as one sit-up. A “set” is a series of
repetitions.)

gram. You should progress at your own pace and be
sensitive to your body’s signals. If you experience pain
or dizziness at any time while exercising, stop immedi-
ately and begin cooling down. Find out what is wrong
before continuing. Remember that adequate rest and a
proper diet are important factors in any exercise pro-
gram.
WARMING UP
The proper amount of weight for each exercise
depends upon the individual user. You must gauge
Begin each workout with 5 to 10 minutes of stretching
your limits and select the amount of weight that is right and light exercise to warm up. Warming up prepares
for you. Begin with 3 sets of 8 repetitions for each
exercise you perform. Rest for 3 minutes after each
set. When you can complete 3 sets of 12 repetitions
without difficulty, increase the amount of weight.

circulation, raising your body temperature and deliver-
ing more oxygen to your muscles.
WORKING OUT
Toning
You can tone your muscles by pushing them to a mod- Each workout should include 6 to 10 different exercis-

amount of weight and increase the number of repeti-
tions in each set. Complete as many sets of 15 to 20
repetitions as possible without discomfort. Rest for 1
minute after each set. Work your muscles by complet-
ing more sets rather than by using high amounts of
weight.
es. Select exercises for every major muscle group,
emphasizing areas that you want to develop most. To
give balance and variety to your workouts, vary the
exercises from session to session.
Schedule your workouts for the time of day when your
energy level is the highest. Each workout should be
followed by at least one day of rest. Once you find the
schedule that is right for you, stick with it.
Weight Loss
To lose weight, use a low amount of weight and
increase the number of repetitions in each set.
Exercise for 20 to 30 minutes, resting for a maximum
of 30 seconds between sets.
EXERCISE FORM
Maintaining proper form is an essential part of an
effective exercise program. This requires moving
through the full range of motion for each exercise, and
Cross Training
Cross training is an efficient way to get a complete and moving only the appropriate parts of the body.
well-balanced fitness program. An example of a bal-
anced program is:
• Plan weight training workouts on Monday,
Wednesday, and Friday.
• Plan 20 to 30 minutes of aerobic exercise, such as
cycling or swimming, on Tuesday and Thursday.
• Rest from both weight training and aerobic exercise
for at least one full day each week to give your body
time to regenerate.
Exercising in an uncontrolled manner will leave you
feeling exhausted. On the exercise guide accompany-
ing this manual you will find photographs showing the
correct form for several exercises, and a list of the
muscles affected. Refer to the muscle chart on page
19 to find the names of the muscles.
The repetitions in each set should be performed
smoothly and without pausing. The exertion stage of
each repetition should last about half as long as the
return stage. Proper breathing is important. Exhale

ideal resting periods are:

each stretch gradually and go only as far as you can
without strain. Stretching at the end of each workout
is an effective way to increase flexibility.
• Rest for one minute after each set for a toning work-
out.
STAYING MOTIVATED
• Rest for 30 seconds after each set for a weight loss
workout.
Plan to spend the first couple of weeks familiarizing
yourself with the equipment and learning the proper
form for each exercise.
For motivation, keep a record of each workout. list the
date, the exercises performed, the weight used, and
the numbers of sets and repetitions completed.
Record your weight and key body measurements at
the end of every month. Remember, the key to
achieving the greatest results is to make exercise a
regular and enjoyable part of your everyday life.
COOLING DOWN
End each workout with 5 to 10 minutes of stretching.
Include stretches for both your arms and legs. Move
