ASSEMBLY

Make Things Easier for Yourself

Everything in this manual is designed to ensure that the weight system can be assembled successfully 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.

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

• The Assembly requires two people.
• Place all parts in a cleared area and remove the packing materials. Do not dispose of the packing materials until assembly is completed.
• Tighten all parts as you assemble them, unless instructed to do otherwise.
• As you assemble the weight system, make sure all parts are oriented as shown in the drawings.
• For help identifying small parts, use the PART IDENTIFICATION CHART in the center of this manual.

The following tools (not included) are required for assembly:

• two adjustable wrenches
• one rubber mallet
• one standard screwdriver
• one Phillips screwdriver
• lubricant, such as grease or petroleum jelly, and soapy water.

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.

6. Make sure that all parts have been properly tightened. The use of all remaining parts will be explained in ADJUSTMENT, beginning on page 15 of this manual. 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 19 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 MAINTENANCE on page 18.

ADJUSTMENT

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. IMPORTANT: When attaching the lat bar or nylon strap, make sure that the attachments are 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.

ADDING WEIGHTS TO THE WEIGHT CARRIAGE

To add resistance to your workout, slide an equal amount of weight (not included) onto each side of the weight tube on the Weight Carriage (19). Make sure that the weights are pushed against the 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 17 to find the actual amount of resistance at each weight station.

ATTACHING THE LAT BAR OR NYLON STRAP TO A PULLEY STATION

Attach the Lat Bar (54) to the Long Cable (58) with a Cable Clip (53). For some exercises, the Chain (52) should be attached between the Lat Bar and the Long Cable with two Cable Clips. Adjust the length of the Chain between the Lat Bar and the Long Cable so the Lat Bar is in the correct starting position for the exercise to be performed. The Nylon Strap (not shown) can be attached in the same manner. The accessories can be attached to the Short Cable (not shown) in the same manner.

ATTACHING AND REMOVING THE SEAT

Set the bracket on the Seat Frame (36) onto the pin on the Front Upright (42). Attach the Seat Frame to the Front Upright with the M8 x 67mm Carriage Bolt (14) and the Seat Knob (40). For some exercises, the Seat (13) must be removed. First, be sure that the chain is not attached to the leg lever. Next, remove the Seat Knob (40) and the M8 x 67mm Carriage Bolt (14) from the Seat Frame (36). Lift the Seat Frame off the Front Upright (42).

ATTACHING THE LEG LEVER TO THE LOW PULLEY STATION

To use the Leg Lever (29), the seat must be attached to the front upright (see ATTACHING AND REMOVING THE SEAT above). Attach one end of the Chain (52) to the M10 x 63mm Eyebolt (35) with a Cable Clip (53). Attach the other end of the Chain to the Short Cable (23) with a Cable Clip. Note: Be sure the Eyebolt is positioned vertically on the Leg Lever.

TROUBLE-SHOOTING 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 Short Cable (23) by tightening the M8 Nylon Locknut (3) at the end of the Cable.

Additional slack can be removed by moving the 90mm Pulley (15) to the other hole in the Long “U”-Bracket (57). Remove the M10 Nylon Locknut (21) and the M10 x 45mm Bolt (12) from the Cable Trap (66), the Pulley, and the “U”-Bracket. Re-attach the Pulley and the Cable Trap to the other hole in the “U”-Bracket 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 DIAGRAM

The cable diagram below shows the proper routing of the Short Cable (23) and the Long Cable (58). Use the diagram to be sure that the two 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. The starting and ending points of each cable are labeled. The small drawings show the correct position of each cable trap. Make sure that the cable traps do not touch or bind the cables.
