I have read many great articles here and am planning a log lift for my homemade splitter.My questions are 1.I have the typical northern log splitter vavle with auto return and 16 gpm pump.Do i need a power beyond valve to replace this valve to utilize the lift or can i use another one of the same in series?2.Also not related to the lift but when i built this splitter this site was unknown to me,so i installed a suction filter cartriage on the pump inlet.Now i know that needs to be removed and install correct filter on the return side,but when my splitter is first ran for about 20 mins. it is slow going.I tried hyd. oil,trans oil,still the same and doesnt matter if winter or spring?my tank is roughly 5 gallons.when it warms up it runs fine.,thanks in advance
