There is a certain resistance in the such cylinders and hoses, so a certain pressure is needed to move things. The pump needs 11-12V I would guess, so just 8.4 V can cause things to move slow. Would try using more voltage first, and then possible check the cylinder more close, if it's easy to move in and out by hand with hoses disconnected, check it for possible dents on outer surface.
