before using the weight system.
1. Read all instructions in this manual and in
the accompanying literature before using the
weight system. Use the weight system only
as described in this manual.
2. It is the responsibility of the owner to ensure
that all users of the weight system are ade-
quately informed of all precautions.
3. The weight system is intended for home use
only. Do not use the weight system in any
commercial, rental, or institutional setting.
4. Use the weight system only on a level sur-
face. Cover the floor beneath the weight sys-
tem to protect the floor.
5. Make sure all parts are properly tightened
each time you use the weight system.
Replace any worn parts immediately.
6. Keep children under the age of 12 and pets
away from the weight system at all times.
7. Always wear athletic shoes for foot protec-
tion.
8. Keep hands and feet away from moving parts.
9. Never release the press arm, butterfly arms,
military press arm, leg lever, leg press plate,
lat bar or nylon strap while weights are
raised. The weights will fall with great force.
10. Always disconnect the lat bar from the
weight system when performing an exercise
that does not use the lat bar.
11. Keep your hands away from the leg press
upright when the military press arm is being
used. Your hand could become pinched
between the leg press upright and military
press arm.
12. Always stand on a foot plate when perform-
ing an exercise that could cause the weight
system to tip.
13. The weight system is designed to support a
maximum user weight of 250 pounds.
14. Make sure that the cables remain on the pul-
leys at all times. If the cables bind while you
are exercising, stop immediately and make
sure that the cables are on all of the pulleys.
15. If you feel pain or dizziness at any time while
exercising, stop immediately and begin cool-
ing down.
16. The decals shown
here have been
placed on the weight
system in the loca-
tions shown on page
4. If a decal is miss-
ing, or if it is not legi-
ble, please call our

Before beginning assembly, carefully read the
following information and instructions:

assembly will require several hours. By setting
aside plenty of time and by deciding to make the
task enjoyable, assembly will go smoothly. You
may want to assemble the weight system over a
couple of evenings.
•Place all parts of the weight system in a cleared
area and remove the packing materials; do not
dispose of the packing materials until assembly is
completed.
•Assembly is divided into four stages: 1) frame
assembly, 2) press and butterfly arm assembly,
3) cable and pulley assembly, and 4) seat and
backrest assembly. The hardware for each stage
is packaged separately.
•Wait until you begin each assembly stage to open
the parts bag labeled for that assembly stage.
•For help identifying the small parts used in
assembly, use the PART IDENTIFICATION
CHART located in the center of this manual.
Note: Some small parts may have been pre-
attached for shipping. If a part is not in the parts
bag, check to see if it has been pre-attached.
•Tighten all parts as you assemble them, unless
instructed to do otherwise.
•Assembly requires two persons. For your conve-
nience and safety, assemble the weight system
with the help of another person.
•As you assemble the weight system, be sure that
all parts are oriented as shown in the drawings.
THE FOLLOWING TOOLS (NOT INCLUDED) ARE
REQUIRED FOR ASSEMBLY:
•Two (2) adjustable wrenches
•One (1) standard screwdriver

44. Remove the adhesive backing from the PRO 9400 decal and apply it to the Front Upright (42).
45. Make sure that all parts have been properly tightened. The use of the remaining parts will be explained in
ADJUSTMENTS, beginning on page 21 of this manual.
Before using the weight system, pull each cable a few times to be 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 installed, they may be damaged when heavy weight is used. See the CABLE
DIAGRAMS on page 25 and 26 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 TROUBLE-SHOOTING AND MAINTE-
NANCE on page 24.
