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 MUSCLE BUILDER 1000.
■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 MUSCLE BUILDER 1000 remain on the unit. DO NOT alter warning
labels and placards. BE SURE that each user reads and understands the information shown on all labels and placards (safety,
instructional and/or other).
■Instruct all users on the proper use of the MUSCLE BUILDER 1000, as well as those actions that should be avoided.
■Your MUSCLE BUILDER 1000 have been designed to accommodate a wide variety of body types. Prior to use, mount the unit
and adjust the bench height to ensure comfortable use.
PRODUCT USE AND MAINTENANCE
Repair of the MUSCLE BUILDER 1000 should be performed only by authorized persons.
NEVER modify the MUSCLE BUILDER 1000 or attempt to make adjustment(s) to, or the repair of, the unit equipment without first calling
CORE HOME FITNESS Product Support. Always notify authorized personnel to make such repairs.
Instruct all users to report any equipment or training irregularities to supervisory personnel IMMEDIATELY.
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.
EXERCISE GUIDELINES

10 CORE HOME MUSCLE BUILDER 1000 OWNER’S MANUAL
MAINTENANCE SCHEDULE
CORE HOME FITNESS strongly recommends performing regular preventive maintenance on your MUSCLE BUILDER 1000. 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 wornor damaged, the unit shouldbe removed
from service until repairs can be made. Only components supplied or approved by CORE HOME FITNESS shall be used to maintain
and/or repair the unit.
DAILY MAINTENANCE
■Wipe down and inspect the framework and other structural components. Check all attaching hardware for security. Tighten as
needed.
■Clean and inspect the cushions and the hand grips. Check all attaching hardware for security. Tighten as needed.
WEEKLY MAINTENANCE
■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 12 for illustrations and part numbers of standard labels and placards used on CORE HOME
FITNESS products).
QUARTERLY MAINTENANCE
■Apply wax to powder-coated areas of the framework and other structural components.
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, 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 CORE HOME FITNESS 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.
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.
