General Safety and Maintenance Manual: Annual Maintenance 26
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 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 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 cloth.
