To my knowledge the system was installed at the factory.For the pins should you be able to move them by hand? or just when the system is injeecting the grease? Would the timer be under the grease bucket or would it be in a fuse block area? As far as the grease it self..around here the coldest it gets is zero for very limited amounts of time...generally in the 20s until late feb then starts warming up through the 30s. the blue is a number two grease but seems to "Run" pretty easily. Thanks for the reply!!
