How to Bleed the Hydralics on a Splitter

Hydraulic log splitters ease the task of splitting wood for your wood burning stove or fireplace. A log splitter relies on hydraulic pressure to force a log against the wedge, splitting the log in half. When air enters the hydraulic system, the ram of the log splitter loses power, as air displaces hydraulic fluid, reducing the pressure applied to the splitter's ram. Removing air from the hydraulic system of your log splitter brings power back to the hydraulic ram, and you should include the bleeding the ram as part of a standard maintenance program.

A log splitter eases the labor involved with splitting wood.

Step 1

Put on your safety glasses.

Step 2

Extend the hydraulic ram to its full forward position with the ram control switch on power models or by pumping the handle of manually operated log splitters.

Step 3

Turn the oil filler plug counter-clockwise by hand or with the adjustable wrench (If needed) to remove the oil filling plug from the log splitter.

Step 4

Release the hydraulic ram by turning the release screw counter-clockwise. Allow the ram to retract until you see hydraulic fluid flow from the oil filling plug hole. Quickly turn the release screw clockwise to stop the ram from retracting.

Step 5

Replace the oil filling plug onto the log splitter. Make sure the plug is tight before using the log splitter, as a loose oil filling plug will allow air to re-enter the splitter's hydraulic system.
