Star Trac Leg Curl Owner's Manual page 9

PRODUCT USE AND MAINTENANCE
Repair of the INSTINCT LEG MACHINES should be performed only by authorized persons.
NEVER modify the INSTINCT LEG MACHINES or attempt to make adjustment(s) to, or the repair of, the unit equipment with-
out first calling STAR TRAC Product Support. Always notify authorized personnel to make such repairs.
Instruct all users to report any equipment or training irregularities to supervisory personnel IMMEDIATELY.
CAUTION: Do not "high pin" and/or "double pin" a weight stack. This action is con-
sidered to be dangerous to users, and bystanders, and may damage your INSTINCT
LEG MACHINES. 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
Star Trac strongly recommends performing regular preventive maintenance on your STAR TRAC INSTINCT LEG MACHINES.
Without regularly scheduled maintenance, normal wear and tear may cause cumulative effects, such as misalignment or prema-
ture wear, resulting in downtime. For this reason, we highly recommend following the maintenance schedules. Additionally, unusu-
al 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 Star Trac shall be
used to maintain and/or repair the unit.

AILY AINTENANCE
Wipe down and inspect the framework and other structural components (see F
requirements). Check all attaching hardware for security. Tighten as needed.
Clean and inspect the upholstered cushions and the hand grips (see U
ments).
Clean and lubricate 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 belt for proper tension (weight belt deflection at any point
should not exceed 25 mm); adjust as needed. (See W
Check leverage arm bearings for evidence of sticking or binding; lubricate as needed (bearings are equipped with fitting to
facilitate lubrication).

EEKLY AINTENANCE
Check the retainer screws at the weight stack top plate and leverage arm or range-of-motion flywheel, as appropriate 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 30 for illustrations and part numbers of standard labels and placards used on

Tighten the nuts securely.
Align the two drilled holes in the upper cross-
beam (4) with the mating holes in the side
beam of the weight stack frame (1). Secure the

screws (72), four washers (78), and two lock
nuts (75). Tighten the nuts securely.
Position the main frame (2) so the two drilled
holes in the lower crossbeam (3) and the two
drilled holes in the upper crossbeam (4) are
