    I got the 4-ton splitter about a year ago and tried it outto see if it worked, but have not used it since. The manual advises to lube it with lithium grease but it is not clear, at least to me, about exactly where to apply it. I called them up but still didn't get a response that helped.
    It sounds like one of the places it's to be lubed is on the frame where the log rests but that doesn't seem to make sense to me, it's not a moving part.
    Anybody have the answer for me?

    On my splitter, the beam or frame where the log rests is also the place where the large splitting wedge on the end of the hydraulic cylinder slides, so lubing it makes sense. I just spread some wheel bearing grease there, mostlly along the edges where the wedge carrier slides.

    Yours may be different.

    here is the manual for I think your model of spliter _SO _051020.pdf

    or there page on manuals,

    in reading through it the only place I see the statment is to use some grease as rust preventive in seasonly storage on the wedge, and to check the oil level, I don't see any directions to lube any thing,
    from manual

    "Regular Maintenance Checklist before each use:
    �� Clean the log ram and guides.
    �� Check the Splitting Wedge for sharpness (page 19).
    �� Check the general condition of the wood splitter, e.g.; nuts, bolts, welds etc.
    Before each season:
    Check the hydraulic fluid level (page 19). Use an AW32 hydraulic fluid for operation over
    40°F and Dextron automatic transmission fluid for operation below 40°F.

    WARNING! When performing any maintenance, you must first unplug the
    wood splitter from the power source and make sure the
    hydraulic system is depressurized and the fluid has cooled.
    Read the "Safety Considerations" chapter of this manual before
    performing any repairs or maintenance.

    Important! Do not drain the hydraulic fluid. Just add enough to replenish the
    lost volume.

    then there is a section on how to check the oil level and fill,
    Adjusting the Hydraulic Fluid Level
    Tools Needed:
    �� Adjustable Wrench
    �� Small Phillips Screwdriver
    1. Check the hydraulic fluid level by tipping the wood splitter up on the wheels and
    2. Clean the area around the Hydraulic Fluid Fill/Drain Port. See Figure 5 on page 12.
    Loosen the Bleed Screw. Then, using the adjustable wrench, unscrew the Dipstick
    located in the Hydraulic Fluid Fill/Drain Port.
    3. Clean the Dipstick and replace it without screwing down to check the level; it
    should be between the two marks on the Dipstick. If the fluid is too high, simply
    pour out a little at a time into a suitable container by tilting the wood splitter. If the
    fluid is too low, add an AW32 hydraulic fluid, a little at a time until the level falls
    between the two marks on the dipstick.
    4. Clean the Dipstick and the O-ring seal thoroughly and reinstall being careful not to
    damage the threads of the aluminum Hydraulic Fluid Cylinder End Cover.
    5. Open the Air Bleed Screw using a small Phillips screwdriver 4 turns and cycle the
    ram back and forth 3 or 4 times to purge any air from the hydraulic system (Figure 4
    on page 11).

    Sharpening the Wedge
    Tool Needed:
    �� Fine-Toothed Flat File
    Before each splitting session, check the sharpness of the wedge. As required, remove
    any burrs or flat spots on the wedge blade using a fine-toothed flat file.


    End of Season & Storage
    �� Wipe down the wood splitter to remove any moisture, wood chips and dirt that
    may have accumulated on the log guide rails, hydraulic control and motor fan
    �� Apply a thin coating of oil or #2 Lithium Grease to the wedge cutting edge to
    prevent rust.
    �� Store the DR 4 -Ton WOOD SPLITTER in a dry area to prevent moisture from
    damaging the electrical components of the machine.
    �� Make sure that the Air Bleed Screw is tightened (See Figure 4 on page 11).
