ADJUSTMENTS, beginningon the following page.
Before usingthe weightsystem,pull each cable a few timesto be surethat the cables movesmoothlyover
the pulleys. If one of the cables does not move smoothly,find and correctthe problem. IMPORTANT: If the
cables are not properly Installed, they may be damaged when heavy weight Is used. Sea 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.

ADJUSTMENTS
The instructionsbelowdescribe how each part o!the weightsystem can be adjusted. Refer to the exemise
guide accompanyingthis manualto see how the weightsystem shouldbe set up for each exercise.IMPOR-
TANT: When using an accessory, make sure It Is In the cor_=ct starting position for the exercise to be
performed. If there Is any slack In the cables or chain as an exercise Is performed, the effecUveness of
the exercise will be reduced.
ATTACHING THE ACCESSORIES TO A PULLEY
STATION
Attachthe I_atBar (59) tothe Low Cable (71) at the
low pulleystationwith a Cable Clip (58). For some
exercises,the Chain (57) shouldbe attachedbetween
the LatBar and the Low Cable withtwoCable Clips.
Adjust the length of the Chain between the Lat Bar
end 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 accessoriescan be attached
tothe ab pulleystationor highpulleystationinthe
same manner.
ADJUSTING THE LEG PRESS PLATE
To adjust the positionof the Leg Press Plate (16), pull
out theAdjustmentPin (40) and slide theAdjustment
Tube (15) eitherbackward or forward inthe bracket
on the Leg Press Lever (14). Line up one ofthe
adjustmentholes in the AdjustmentTube with the
hole in the bracketand re-insertthe AdjustmentPin.
ATTACHING THE CURL PAD
To usethe Curl Pad (22), removethe 2"Square Inner
Cap (67) from the ButterflyLeg (11). Slidethe Curl
Post (21) to the desired height inths ButterflyLeg.

CHANGING THE WEIGHT SETTING
To change the settingof a weightstack, insert a
Weight Pin (81) under the desired Weight (41). insert
the Weight Pin so that the bent end touchesthe
weight stack.Turn the bent end down.
To use the BottomWeight (47) withthe press arms or
the leg press, insertthe Weight Pin (81) under the
BottomWeight. Remove the otherWeight Pin from
the small weight stack.
To use the small weight stack withthe press arms or
leg press, inserta Weight Pin (81) underthe Bottom
Weight (47). Then, insertthe other Weight Pin under
the desired Weight (41) in the rightweight 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.
26
WEIGHT RESISTANCE CHART
The chart below shows the approximateweightresistanceat each exercise station."Left Top"and =RightTop"
refer to the 6 lb. top weights. =Bottom" refers tothe 12.5 lb. bottomweight. The othernumbers refer to the 12,5
lb.weight plates. Weight resistanceshownfor the butterflyarm stationisfor each butterflyarm. 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 properlytightened each time you usethe weightsystem. Replace any wornpartsimmedi-
ately.The weight system can be cleaned using a damp clothand mild non-abrasive detergent. Do not use solvents.
TIGHTENING THE CABLES
Woven cable, the type of cable used on the weightsystem, can stretchslightlywhen it isfirst used. If there is
slack in the cables before resistanceisfelt, the cables shouldbe tightened.Slack can be removedfrom the
cables in several differentways.
When you are tighteningthe cables, note that they are linked intotwo 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 tightenedat 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 3 112"Pulley (35), remove the 318"Nylon
Locknut(90) and the 318"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
PressCable (72) attachedto the weight stackscan
be used to tightenthe cables.
To tighten the Rear Cable (70), remove the 5/16" x
1 3/4" Bolt(96) andthe 5/16" NylonLocknut(86) from
the "U"-Bracket(33) and the Short WeightTube (44).
Tightenthe 1/4" Nylon Locknut(103) at the end of the
Rear Cable (70) a few tums. Re-attach the "U"-
Bracket (33) to the ShortWeight Tube (44) withthe
5/16" x 1 3/4" Bolt (96) and the 5/16" NylonLocknut
(86).
The Press Cable (72) can be tightenedinthe same
manner.
9O
Slack can be removedfrom the Press Cable (72) by
movingthe =V"-Pulley (34) attached to the Press Seat
Frame (12) closerto 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 LongCable
Trap (37). Move the Pulleyto a holethat iscloserto
the Press Upright (5), one holeat a time, untilthe
slack isremoved. Reattach the Pulley and Cable Trap
to the hole with the Bolt, Washer, and Nylon Locknut.
I{there isstillslack in the Press Cable (72), move the
"V"-PuUey (34) attached to the small tube on the
Press Upright (5) to a hole that is closerto the
Upright.
Remove the 3/8" x 3 114"Bolt(104), 318"Washer
(97), and 3/8" Nylon Locknut(90) from the Press
Updght (5), the "V"-Pulley (34), and the Long Cable
Trap (37). Move the Pulleyto a holethat iscloserto
the Press Upright,one holeat a time, untilthe slack
is removed. Reattach the Pulley and Cable Trap to
the hole with the Bolt, Washer, and Nylon Locknut,
If a cable slips off the pulleys often, the cable may have become twisted. Remove the cable and re-Install
It. If the cables need to be replaced, see ORDERING REPLACEMENT PARTSon the backcover o!this manual.

for each Cable. Make sure that the Cables are routed correctly, that the Pulleys move smoothly, and that
the Cable Traps do not touch or bind the Cables. Incorrect cable routing can damage the weight system.
