Instructions
Belts require tightening when a lack of resistance and
uneven feel is noticed at the beginning of an exercise. USE
CAUTION AROUND THE WEIGHT STACK WHEN
TIGHTENING KEVLAR™ BELTS.
To adjust belt:
1. Remove the Shielding.
2. Remove the Tethered Weight-Pin from weight stack hole.
See Figure 3.
3. Lift top weight using the appropriate lifting mechanism
- in most cases the moving arms for exercising.
4. While top weight is suspended, insert a shim between
the first and second weight (two quarters will suffice).
5. Release top weight so the first stack is resting on the
shim.
6. Loosen the two bolts at the end of the belt and pull
through excess belting until tight.
7. Tighten belt bolts and lift top weight to remove the shim.
8. Lower the mechanism to rest on the weight stack.
9. If belt is still loose, repeat this procedure until there is
no looseness at the beginning of an exercise.
10. If you experience difficulties in tightening the belts,
please contact your Nautilus service professional or call
1-800-NAUTILUS (1-800-235-2233), Parts & Service
Department, for assistance.

Before Exercising
Safety
1. Supervision is necessary when the machine is
used by or near children, invalids, or disabled
persons.
2. Follow the instructions for specific exercises on
each machine
3. Get in and out of the equipment carefully.
4. Never operate the machine without shields in
place.
5. Use only Nautilus selector pins in weight stack.
Never drop or insert any other object into
machine opening.
6. Use this machine only as intended or described
in this manual.
7. Do not operate equipment with loose or damaged
parts. If machine fails to operate correctly, do not
attempt to repair. Notify authorized personnel of
the problems.
8. Keep hands and feet clear of weights and other
moving parts when in use. Keep hands and feet
only on the hand grips and foot pads provided.
9. Failure to comply with these instructions may
result in personal injury.
To guard against injury, all equipment users
should follow these instructions.
■ Check with your physician and get approval
before beginning a training routine.
■ Become familiar with the equipment before
beginning a training routine.
■ Always warm-up before and cool down after
exercising.
■ Move slowly during each exercise. Do not jerk
or "throw" the weight.
■ Breathe freely. Do not hold your breath while
lifting or lowering weight.
■ Hold movement arms and handles firmly, do
not squeeze or grip tightly.
■ Structure each workout to exercise the largest
muscles first. Suggested routines are found in
the Nautilus Total Fitness Program.
■ Experiment to find the exact weight you need
for each exercise. Select a resistance that allows
you to perform eight to twelve slow repetitions.
Take two seconds to lift the weight. Pause briefly,
and take four seconds to lower the weight.
Stop exercising immediately if you experience a sharp
nerve or joint pain, and seek medical advice.

Hydraulic Unit Adjustment
Note: The hydraulic unit only needs adjustment if the
seat will not stay in position.
1. Remove CLEVIS and COTTER PINS. Remove
CIRCULAR COTTER PINS by lifting up the wire that crosses
over straight end of pin, see Figure 1. Save all PINS.
2. Use a flat blade screwdriver to gently unsnap CABLE
from LEVER MECHANISM. Be careful not to break cable
fitting.
3. Remove hydraulic unit from machine, loosen NUT by
backing it down ROD. Hold LEVER MECHANISM and twist
SHAFT until there is free play in LEVER, as shown by "B" in
Figure 1.
4. Hold LEVER MECHANISM and twist SHAFT (as shown
by "C" in Figure 3) until LEVER free play is gone, then back
off 1/8 turn. Tighten NUT against LEVER MECHANISM. The
NUT MUST BE PROPERLY TIGHTENED to keep hydraulic
unit in adjustment.
5. Twist SHAFT slightly to realign the top and bottom
clevis pin holes.
6. Use pliers to snap and lock the CABLE on to the LEVER
MECHANISM.
7. Reposition the hydraulic unit on machine and insert
CLEVIS and COTTER PINS. The circular COTTER PINS can
be pushed into holes.
8. The HANDLE NUT should be tight against the
HANDLE HOUSING, see Figure 2. The HANDLE LEVER
should touch the GRIP when squeezed. If it does not touch,
adjust as follows:
a. Loosen the HANDLE NUT by turning counter
clockwise.
b. Turn the ADJUSTMENT BARREL clockwise until the
HANDLE LEVER has approximately 1/4" free play.
