Annual Maintenance
You should perform these tasks on an annual basis, as appropriate for
your equipment.
Weight Stack Annual Maintenance
Once a year, you must disassemble the weight stack and thoroughly
clean and inspect it.
• Carefully remove the cable and guide rods from the weight stack.
Completely disassemble the weight stack in a well-ventilated area,
away from the exercise floor.
• Inspect weight plates and clean them thoroughly. Cracked or
broken plates should be replaced immediately (refer to Obtaining
Service to purchase replacements). Clean each plate individually
and inspect guide bushings.
• Inspect the bushings of the top weight plate and replace the plate if
excessively worn or broken.
• Clean the selector stem and inspect it for wear and damage.
• Reassemble the weight stack.
• Wipe down the weight stack enclosures (shrouds) with a damp
cloth as needed. Inspect all fasteners to ensure the shroud is
securely mounted.
Important: Precor recommends that you replace worn and damaged
cables during routine maintenance. All cables should be replaced
annually.

Inspect and Lubricate Pop Pins
Remove the pop pin assembly by loosening the hex head cap.
CAUTION: Pulling out the pop pin may cause the unit to
suddenly adjust position. To avoid injury, keep your hands and
head away from moving parts.
Inspect the plunger and spring for excessive wear and damage, and
replace as required.
Apply a small amount of silicone spray lubricant to the spring and
plunger, and then reinstall the entire assembly. Tighten hex head cap.
Wipe off any excess lubricant with a rag.
