12 NAUTILUS INSTINCT LEG PRESS /CALF RAISE OWNER’S MANUAL
ANCHORING
IMPORTANT: The INSTINCT LEG PRESS / CALF RAISE must be secured to the floor to
stabilize and eliminate rocking or tipping over. This must be performed by a licensed
contractor. Failure to anchor the unit will void the warranty. NAUTILUS shall not be
liable for damage or injury caused by unanchored or improperly anchored units.
The INSTINCT LEG PRESS/ CALF RAISE must be anchored to the floor using through bolts or anchoring studs. Each foot
pad on the unit provides two anchoring holes that will accommodate bolts of up to 12mm (7/16") diameter. Only one hole in each
foot pad is required during anchoring. The holes used for anchoring may be selected based on installation site requirements or
customer preference.
Anchoring bolts/studs must meet the following requirements:
Anchor bolts shall be Grade 8.8 or Grade SAE 5.
Anchoring bolts or studs shall have a minimum size of 6mm (1/4") diameter; 8mm (5/16") diameter bolts/studs are
recommended.
Pull-out force shall be 100kg (2201 lbs) minimum for any single anchor. This will ensure a secure anchoring system and safe
operation of the unit by all users.
GENERAL GUIDELINES
As with any exercise program, strength training involves an element of risk. The information provided in this section will help
you and/or your members make safe and productive use of your NAUTILUS INSTINCT LEG PRESS / CALF RAISE.
ALWAYS consult a physician before beginning any strength-training program. This is particularly important for persons
with known health conditions and/or persons that are not familiar with the risks involved with weight training.
All training sessions should be supervised by trained personnel.
BE SURE that all warning labels and placards affixed to the INSTINCT LEG PRESS / CALF RAISE remain on the unit.
DO NOT alter warning labels and placards. BE SURE that each user reads and understands the information shown on all

Instruct all users on the proper use of the INSTINCT LEG PRESS / CALF RAISE, as well as those actions that should be
avoided.
Your INSTINCT LEG PRESS / CALF RAISE has been designed to accommodate a wide variety of body types. Prior to use,
mount the unit and adjust the seat height to ensure comfortable operation of the leverage arm.
To minimize user and/or bystander injury:
Do not lean the against framework, weight stack or any component, regardless of whether it is dynamic or static.
Stay clear of all components while in a dynamic state of motion. Keep hands and feet away from cables, belts, cams and
pulleys and/or any converging action. The convergence of these transmission-based components can cause serious injury.
Exercising on free weight and selectorized products should be performed with the assistance of a spotter.
PRODUCT USE AND MAINTENANCE
Repair of the INSTINCT LEG PRESS / CALF RAISE should be performed only by authorized persons.
NEVER modify the INSTINCT LEG PRESS / CALF RAISE or attempt to make adjustment(s) to, or the repair of, the unit
equipment without first calling NAUTILUS Product Support. Always notify authorized personnel to make such repairs.
Instruct all users to report any equipment or training irregularities to supervisory personnel IMMEDIATELY.
EXERCISE GUIDELINES

NAUTILUS INSTINCT LEG PRESS /CALF RAISE OWNER’S MANUAL 13
CAUTION: Do not "high pin" and/or "double pin" a weight stack. This action is
considered to be dangerous to users, and bystanders, and may damage your
INSTINCT LEG PRESS / CALF RAISE. Aside from the mechanical damage that
may result, such action(s), in part, may cause the weight stack to crush or pinch
fingers, hands and/or extremities. DO NOT use the unit if the top plate is elevated
and/or pinned in a raised position. Seek assistance from authorized personnel to
correct such a condition.
MAINTENANCE SCHEDULE
Nautilus strongly recommends performing regular preventive maintenance on your NAUTILUS INSTINCT LEG PRESS /
CALF RAISE. Without regularly scheduled maintenance, normal wear and tear may cause cumulative effects, such as
misalignment or premature wear, resulting in downtime. For this reason, we highly recommend following the maintenance
schedules. Additionally, unusual symptoms, such as excessive noise during use, stiffness or free play in moving parts, etc., should
be investigated and necessary corrective actions (adjustment or parts replacement) should be performed. If any components are
found to be worn or damaged, the unit should be removed from service until repairs can be made. Only components supplied or
approved by Nautilus shall be used to maintain and/or repair the unit.
DAILY MAINTENANCE
Wipe down and inspect the framework and other structural components (see FRAMEWORK MAINTENANCE on page 14 for
requirements). Check all attaching hardware for security. Tighten as needed.
Clean and inspect the upholstered cushions and the hand grips (see UPHOLSTERY MAINTENANCE on page 14 for
requirements).
Clean and lubricate the weight stack and seat frame guide rods using a cotton cloth and break-free lubricant. Apply the
lubricant to the cloth, then wipe up and down the guide rods as needed.
Inspect weight belt for excessive wear or other damage. Check weight belts for proper tension (weight belt deflection at any
point should not exceed 25 mm); adjust as needed. (See WEIGHT BELT INSPECTION REQUIREMENTS on page 15 for
requirements.)
WEEKLY MAINTENANCE
Check the retainer screws at the weight stack top plate, range-of-motion flywheel and seat post for security (retainer screws
should be torqued to 400 inch-pounds). Tighten as needed.
Check all labels and placards affixed to the unit for legibility and security. Replace illegible labels and placards as needed
(see LABELS AND PLACARDS on page 16 for illustrations and part numbers of standard labels and placards used on
NAUTILUS INSTINCT products).
MONTHLY MAINTENANCE
Clean tops of bearings at weight stack top plate. Check for heavy buildup on guide rods below top plate (lift half of weight
stack to perform a visual inspection and clean as necessary).
QUARTERLY MAINTENANCE
Apply wax to powder-coated areas of the framework and other structural components.
PREVENTIVE MAINTENANCE

14 NAUTILUS INSTINCT LEG PRESS /CALF RAISE OWNER’S MANUAL
MAINTENANCE PROCEDURES
FRAMEWORK MAINTENANCE
CAUTION: DO NOT use lacquer thinner, acetone, or other solvents to clean powder-coated finishes on the framework
or other structural components. Solvents will dull the finish, and contain components that may remove the epoxy-
based powder from the frame.
Framework and other structural components should be wiped down on a daily basis using a moistened with water. This will increase
the longevity of protective powder-coat finishes. The framework should be inspected while cleaning for evidence of fatigue cracks,
scratches or chips in the finish, loose hardware, worn or damaged weight belt, and other areas that may require attention.
Apply easy-application car wax to all powder-coated surfaces quarterly. Regular waxing will aid in preventing premature rusting
due to corrosives found in perspiration, and will allow loose particles to be removed more easily when performing the daily wipe-
down.
Procedures to repair scratches and chips depend on the severity of the damage:
Surface scratches can generally be repaired by polishing with an automotive rubbing compound.
Deep scratches and chips must be repaired by filling the damaged area using a “touch-up” bottle of color-matched paint
(available through the NAUTILUS Parts Department). Fill the damaged area sparingly, using two or more coats. Allow the
area to dry thoroughly between coats. Once the touch-up is complete, it can be left “as is”, or it can be blended and color-
sanded to the surrounding surface.
NOTE: The process of blending and sanding repaired areas to the surrounding surface is difficult. It should be attempted ONLY
by persons knowledgeable in this area.
The weight stack shrouds are made of PETG (glycol-modified polyethylene terephthalate). Proper cleaning is necessary to
preserve the appearance of the shrouds. The following cleaners are compatible with PETG: Original Dawn®, Freon® T.F.,
Palmolive Liquid®, Top Job® and Windex® with Ammonia D.
CAUTION: Use ONLY recommended cleaning agents and procedures when cleaning the weight stack shrouds:
DO NOT use abrasive or highly alkaline cleaners to clean the shrouds.
DO NOT use scrape the shrouds with squeegees, razor blades or other sharp instruments. DO NOT scrub or use
brushes on the shrouds.
DO NOT use Benzene, gasoline, acetone or tetrachloride to clean the shrouds.
DO NOT clean the shrouds in hot sun or at elevated temperatures.
Wash the shrouds using a clean sponge or soft cloth, and a solution of mild soap or detergent and lukewarm water. Rinse well
with clean water, and dry thoroughly with a chamois or moist cellulose sponge to prevent water spots.
Remove stubborn accumulations (paint, grease, scuff marks) before drying by rubbing lightly with Isopropyl alcohol. Remove
labels, placards or other adhesive residue using kerosene. If solvent does not penetrate the adhesive, heat the area using a hand-
held blow dryer to soften the adhesive and aid in removal.
Clean all areas treated with solvent using a clean sponge or soft cloth, and a solution of mild soap or detergent and lukewarm
water. Rinse thoroughly with clean water.
UPHOLSTERY MAINTENANCE
CAUTION: DO NOT use cleaners such as Lysol®, Armor All®, Windex®, or other abrasive detergents to clean
upholstered surfaces. These products will remove moisture from the Naugahyde® upholstery, resulting in
premature cracking.
Upholstered cushions should be cleaned on a daily basis to prevent damaged due to corrosives found in perspiration.
Wipe the top and sides of upholstered cushions using a cloth moistened with a solution of one part lanolin hand cleaner to nine
parts water. After cleaning, wipe down using a dry towel to remove any residue.
