Inspect and Lubricate Pop Pins
Remove the pop pin assembly by loosening the cap.
CAUTION: Pulling out the pop pin may cause the unit to adjust position
suddenly. 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 Teflon
®
spray lubricant to the spring and plunger, and
then reinstall the entire assembly. Tighten the cap. Wipe off any excess
lubricant with a cloth.
