heavy duty door opener squeaks

A home owner from Falls Church says:
I received the heavy duty door opener, 40-181. The last three days I've had a squeaking noise operation issue with the area around the hydrolic shaft. Each time the door is opened/closed, it makes a sound the kid's say sounds like an elephant call :>) . Can this be lubricated and with what type of lubricant. Or should it be replaced? Thanks

I actually recently installed the 40-181 closer myself and it also squeaked. I'm thinking maybe I tightened the carriage bolt too tightly on the spring pack. What I did was use a spray lubricant around the edge of the spring pack where the top and bottom come together. It did the trick in eliminating the squeak.
