Vitality Series Selectorized Line Owner's Manual: Maintenance 39
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.
