How to check the hydraulic oil level and sharpen the cutting wedge. The edge on my unit when brand new was rather rounded. Since mine is only a 4 ton unit it needs all the help, thus a sharpened wedge helps sometimes. The manuals say to use a file. Here I use a grinder first then a file since mine was rather blunted with cutting Live Oak pieces last year.
Harbor Freight first sold the 4 ton units 40318 circa 1999 and 93815 circa 2006 . Also sold were a 7 ton 97113 circa 2007 The current model is 5 ton 61373 circa 2013. Since all these are made in China the same type units are the Homelite UT49103 at Home Depot etc. Dr Power 5 ton electric is similar too.
