28. Make sure that all parts have been properly tightened. The use of all remaining parts wilt be explained
in ADJUSTMENT, beginning on page 15 of this manual.
Before using the home gym, 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. IMPOR-
TANT: 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-SHOOT-
ING AND MAINTENANCE on page 18.

ADJUSTMENT
The instructions below describe how each part of the home gym can be adjusted. Refer to the exercise poster
accompanying this manual to see how the home gym 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, slk_e 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 and
that the amount of weight on each end of the weight
tube is the same. Note: Due to the cables and pul-
leys, 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
THE HIGH 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.
ATTACHING THE LAT BAR OR NYLON STRAP TO
THE LOW PULLEY STATION
Attach the Lat Bar (54) to the Short Cable (23) with a
Cable Clip (53). For some exercises, the Chain (52)
should be attached between the Lat Bar and the
Pulley 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 starting
position for the exercise to be performed,
The Nylon Strap (not shown) can be attached in the
same manner.
