ASSEMBLY

Make Assembly Easier for Yourself

Everything in this manual is designed to ensure that the weight system can be assembled successfully by anyone. Before begin-

ning assembly, make sure to read the information on this page. This brief introduction will save you much more time than it takes to read it.

Assembly Requires Two Persons

Make sure you have the following tools:

• Two adjustable wrenches

• One standard screwdriver

• One phillips screwdriver

• One rubber mallet

• You will also need grease or petroleum jelly, a

small amount of soapy water, and clear tape or masking tape.

For your convenience and safety, assemble the weight system with the help of another person.

Set Aside Enough Time

Due to the many features of the weight system, the assembly process 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.

Select a Location for the Weight System

Because of its weight and size, the weight system should be assembled in the location where it will be used. Make sure that there is enough room to walk around the weight system as you assemble it.

How to Unpack the Box

To make assembly as easy as possible, we have divided the assembly process into four stages. The parts needed for each stage are found in individual bags. Important: Wait until you begin each stage to open the parts bag for that stage. 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.

Note: 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.

How to Identify Parts

To help you identify the small parts used in assembly, we have included a PART IDENTIFICATION CHART in the center of this manual. Place the chart on the floor and use it to easily identify parts during each assembly step. Note: Some small parts may have

been pre-attached. If a part is not in the parts bag, check to see if it has been pre-attached.

How to Orient Parts

As you assemble the weight system, make sure that all parts are oriented exactly as shown in the drawings.

Tightening Parts

Tighten all parts as you assemble them, unless instructed to do otherwise.

Questions?

If you have questions after reading the assembly instructions, please call our toll-free HELPLINE at 1-800-736-6879, Monday through Saturday, 7 a.m. until 7 p.m. Central Time (excluding holidays).

The Four Stages of the Assembly Process

Frame Assembly—You will begin by assembling

the base and the uprights that form the skeleton of the weight system.

Arm Assembly—During this stage you will assemble the arms and the leg lever.

Cable Assembly—During this stage you will attach the cables and pulleys that connect the arms to the weights.

Seat Assembly—During the final stage you will assemble the seats and the backrests.

cables are not properly installed, they may be damaged when heavy weight is used. See the CABLE DIAGRAMS on pages 30 and 31 for proper cable routing. If there is any slack in the cables, you will need to remove it by tightening the cables; see TROUBLESHOOTING AND MAINTENANCE on page

28.

Page 25

ADJUSTMENTS

The instructions below describe how each part of the weight system can be adjusted. Refer to the exercise guide accompanying this manual to see how the weight system should be set up for each exercise. IMPOR-

TANT: When using an accessory, make sure it is in the correct starting position for the exercise to be performed. If there is any slack in the cables or chain as an exercise is performed, the effectiveness of the exercise will be reduced.

ATTACHING THE ACCESSORIES TO A PULLEY STATION

Attach the Lat Bar (59) to the Low Cable (71) at the low pulley station with a Cable Clip (58). For some exercises, the Chain (57) should be attached between the Lat Bar and the Low Cable with two Cable Clips.

Adjust the length of the Chain between the Lat Bar and the Low Cable so the Lat Bar is in the correct starting position for the exercise to be performed.

The Nylon Strap (83) or Ab Strap (56) can be attached in the same manner. The accessories can be attached to the ab pulley station or high pulley station in the same manner.

ADJUSTING THE LEG PRESS PLATE

To adjust the position of the Leg Press Plate (16), pull out the Adjustment Pin (40) and slide the Adjustment Tube (15) either backward or forward in the bracket on the Leg Press Lever (14). Line up one of the adjustment holes in the Adjustment Tube with the

hole in the bracket and re-insert the Adjustment Pin.

ATTACHING THE CURL PAD

To use the Curl Pad (22), remove the 2” Square Inner Cap (67) from the Butterfly Leg (11). Slide the Curl Post (21) to the desired height in the Butterfly Leg. Tighten the Curl Knob (49) into the Butterfly Leg and an adjustment hole in the Curl Post.

Page 26

CHANGING THE WEIGHT SETTING

41 To change the setting of a weight stack, insert a Weight Pin (81) under the desired Weight (41). Insert the Weight Pin so that the bent end touches the weight stack. Turn the bent end down.

To use the Bottom Weight (47) with the press arms or the leg press, insert the Weight Pin (81) under the Bottom Weight. Remove the other Weight Pin from the small weight stack.

To use the small weight stack with the press arms or leg press, insert a Weight Pin (81) under the Bottom Weight (47). Then, insert the other Weight Pin under the desired Weight (41) in the right weight stack.

Note: Due to the cables and pulleys, the amount of resistance at each exercise station may vary from the weight setting. Use the WEIGHT RESISTANCE CHART on page 27 to find the approximate amount of resistance at each weight station.

Page 27

WEIGHT RESISTANCE CHART

The chart below shows the approximate weight resistance at each exercise station. “Left Top” and “Right Top” refer to the 6 lb. top weights. “Bottom” refers to the 12.5 lb. bottom weight. The other numbers refer to the 12.5 lb. weight plates. Weight resistance shown for the butterfly arm station is for each butterfly arm. Note: The actu-

al resistance at each station may vary due to differences in individual weight plates as well as friction between the cables, pulleys, and weight guides.

TROUBLESHOOTING AND MAINTENANCE

Make sure all parts are properly tightened each time you use the weight system. Replace any worn parts immediately. The weight system can be cleaned using a damp cloth and mild non-abrasive detergent. Do not use solvents.

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. Slack can be removed from the cables in several different ways.

When you are tightening the cables, note that they are linked into two distinct groups. The Rear Cable (70), the Low Cable (71), the Butterfly Cable (73), and the Ab Cable (74) are all connected to the small weight stack. All three cables will be tightened by tightening the Rear Cable at the small weight stack, or by adjusting the 3 1/2” Pulleys (35) in either set of Pulley Plates (32).

The Press Cable (72) is attached to the large weight stack. The Press Cable can be tightened at the large weight stack or by moving the “V”-Pulleys (34) on the Press Upright (5) and the Press Seat Frame (12).

The Pulley Plates (32) have four sets of adjustment holes for each 3 1/2” Pulley (35). Slack can be removed from the cables by moving one or both Pulleys to a set of holes closer to the center of the Pulley Plates.

To move a 3 1/2” Pulley (35), remove the 3/8” Nylon Locknut (90) and the 3/8” x 2” Bolt (93) from the Pulley Plates (32), the Cable Trap (38), and Pulley. Re-attach the Pulley and Cable Trap to the next set of holes in the Pulley Plates with the Bolt and Nylon Locknut. Note: Begin by moving the bottom Pulley

up one set of holes. If the cables are still too loose, move the top Pulley down one set of holes, until the slack in the cables has been removed.

The threaded ends on the Rear Cable (70) and the Press Cable (72) attached to the weight stacks can be used to tighten the cables.

To tighten the Rear Cable (70), remove the 5/16” x 1 3/4” Bolt (96) and the 5/16” Nylon Locknut (86) from the “U”-Bracket (33) and the Short Weight Tube (44).

Tighten the 1/4” Nylon Locknut (103) at the end of the Rear Cable (70) a few turns. Re-attach the “U”Bracket (33) to the Short Weight Tube (44) with the 5/16” x 1 3/4” Bolt (96) and the 5/16” Nylon Locknut (86).

Slack can be removed from the Press Cable (72) by moving the “V”-Pulley (34) attached to the Press Seat Frame (12) closer to the Press Upright (5).

Remove the 3/8” x 4 1/4” Bolt (85), 3/8” Washer (97), and 3/8” Nylon Locknut (90) from the Press Seat Frame (12), the “V”-Pulley (34), and the Long Cable Trap (37). Move the Pulley to a hole that is closer to the Press Upright (5), one hole at a time, until the slack is removed. Reattach the Pulley and Cable Trap to the hole with the Bolt, Washer, and Nylon Locknut.

If there is still slack in the Press Cable (72), move the “V”-Pulley (34) attached to the small tube on the Press Upright (5) to a hole that is closer to the Upright.

Remove the 3/8” x 3 1/4” Bolt (104), 3/8” Washer (97), and 3/8” Nylon Locknut (90) from the Press Upright (5), the “V”-Pulley (34), and the Long Cable Trap (37). Move the Pulley to a hole that is closer to the Press Upright, one hole at a time, until the slack is removed. Reattach the Pulley and Cable Trap to the hole with the Bolt, Washer, and Nylon Locknut.
