Weekly Maintenance - Precor Vitality Series Maintenance Manual

In addition, check the following:
Ensure that each cable is properly adjusted and
l
tightened at the top of the weight stack.
Check cable pulleys, end connections, and end
l
fittings. Ensure all connections are tight, adjust
cable tension as necessary.
Ensure that the cable bolt is threaded a minimum
l
of seven (7) threads/turns into the selector stem,
and the locking jam nut is tight (Figure 3).

Weekly maintenance

Condition and Clean Upholstery
Condition and deep clean the upholstery weekly with a lanolin-based hand cleaner or upholstery
cleaner.
Important: To clean the upholstery, do not use cleaning products that have any of these ingredients:
solvents, alcohol, ammonia, or petroleum. Use a mild detergent-based cleaner instead.
Clean and Lubricate Guide Rods
Note: On the Vitality Series, the upper rear shroud must be removed to access the guide rods for
inspection, cleaning, and lubricating. See Shroud Removal section.
Inspect the exposed areas of the guide rods for cleanliness. Using a dry cloth, wipe any buildup of dirt
or grease from the rods.
Lubricate the exposed areas of the guide rods by applying a light coat of Teflon® spray lubricant.
Spray the lubricant on a cloth and then wipe the guide rods with the cloth. Be careful with any
lubricant spray; it can stain carpet and clothing.
Note: Do not use petroleum-base lubricants. These lubricants tend to cause a rapid buildup of direct
and hair on the weight plates, which can cause the plates to stick together.
CAUTION: Do not attempt to lubricate the guide rods when the equipment
is in use. Attempting to lubricate between the weight plates without
complete disassembling the stack will result in serious injury.
Inspect Cables, Connections, and Tension
Each week, give the cables and connections a thorough inspection and check cable tensions. The
following lists the specific things you need to inspect:
Check the cable termination at the weight stack. For most equipment, the exposed shank can
l
be no more than 1¼ inches (32mm); this distance allows for a minimum of 10 turns of the bolt
into the selector stem (refer to Inspect Cables and End Connections, earlier). Check and adjust
the distance accordingly. Also make sure that the locking jam nut is tight against the selector
stem.
Check the cable, especially near all pulley wheels and cams.
l
Check the cable as it terminates at the cam, which is stationary on most equipment. Inspect
l
the bolt passing through the cam end fitting to be sure the two jam nuts are tightened against
each other. Also, check the entire cable routing to verify that there is no interference with any
structure.
Inspect the ball end of the cable where the cable connection rests in the clevis housing.
l
Make sure that each cable is properly adjusted and tightened at the top of the weight stack.
l
Check cable pulleys, end connections, and end fittings. Make sure all connections are tight,
l
adjusting cable tension as necessary.
Inspect Cable Handle Attachments
Figure 3
Check the cable-to-handle attachment area very
closely (Figure 4). Look for frayed cable ends,
broken thimbles, bent cables, worn spring clips,
worn handles, and any other unusual wear.
Also, check the spring clip gate and make sure it
closes properly and engages securely (Figure 5).
Check the spring clip, links, and cable; replace
any spring clip link that does not function
properly or shows wear.
Inspect Pulleys
Precor uses precision ball bearing idler pulleys to guide the cable smoothly.
Inspect each pulley for damage, including hairline cracks, chips, or missing sections. Worn surfaces in
the pulleys can cause severe damage to the cables and must be replaced at the first sign of wear or
damage.
Be certain that the wheels turn freely as the equipment is used. Inspect each pulley for excessive side-
to-side play, which indicates worn bearings or loose mounting bolts. If excessive play is discovered,
remove the pulley to inspect the bearings and replace the entire pulley if necessary.
Inspect Weight Stack and Selector Pin
Weight stacks are made of precision machined plates that are designed as a single mechanism to
stack precisely. Use only Precor-supplied add-on weights and weight selector pins.
On a weekly basis, inspect weight stacks and selector pins. Wipe each plate with a damp cloth as
needed. Inspect all plates for sharp burrs or damage. Wipe dirt and dust off the guide rods.
Make sure the equipment uses only the original Precor selector pin. In addition, make sure the
selector pin can be fully inserted and retained in each weight plate.
Inspect and Lubricate Bearings and Bushings
Precor uses high quality bearings designed for strength applications and long service life. Each week,
do the following to maintain the bearings and bushings on the equipment:
