• Linear Bearings: These bearings allow weight plates and other
mechanical parts to travel smoothly along guide rods. (Refer to the
following figure.) Inspect the ends of each guide rod to make sure they are
fastened correctly and all bolts are tight.
Wipe down guide rods using a light application of a silicone spray lubricant to
remove dust, hair, and dirt. Polish the guide rods using fine grade steel wool if
surface rust is present.
Important: Do not use petroleum-based lubricants.
If you lubricate the guide rods regularly, then the bearings will function as
designed. Otherwise, the guide rods may corrode. This can cause the bearings
to become clogged and jammed, leading to actual gouging of the guide rods.
Be sure to remove surface rust and oxidation from the guide rods as soon as
you observe it.

Check and Lubricate Seat Adjustment
The seat adjustment mechanism requires little maintenance. However,
because seat safety is important to the safety of a workout, you should check
the ratcheting seat lever regularly to see if it sticks when used.
To test if the seat lever needs lubrication, elevate the seat slightly while
pressing and releasing the lever. The lever should snap back out easily. If the
lever sticks, lubricate its pivot pin with silicone spray lubricant. Wipe off any
excess lubricant with a cloth.
