how do you bleed hydraulics on a log splitter

^{Steps For Bleeding a Log Splitter:}

1. Please, put on your safety goggles. Push the hydraulic ram extending to its full forward position by the control switch.
2. Turn the oil-filler plug counter-clockwise to remove the oil filling plug from a log splitter.
3. Release the ram by rotating the release screw counter-clockwise. Allow the ram to retract until you see hydraulic oil coming out from the oil filling plug hole.
4. Now, replace the oil filling plug onto the splitter again. Tighten properly to eliminate air entrance again.

How do you change the oil in a hydraulic log splitter?

Push the hydraulic ram extending to its full forward position by the control switch. Turn the oil-filler plug counter-clockwise to remove the oil filling plug from a log splitter. Release the ram by rotating the release screw counter-clockwise. Allow the ram to retract until you see hydraulic oil coming out from the oil filling plug hole.

How to replace hydraulic oil splitter ram?

Release the ram by rotating the release screw counter-clockwise. Allow the ram to retract until you see hydraulic oil coming out from the oil filling plug hole. Now, stop the ram by rotating the screw clockwise right away. Now, replace the oil filling plug onto the splitter again.

What are the most common problems with a log splitter?

A well-maintained log splitter will ensure that both your log splitter, and you, can continue to split cord after cord of wood. Some other common maintenance concerns, in addition to old hoses, are: dirty or contaminated hydraulic fluid, a rusty hydraulic ram or damaged shaft seal, loose engine parts or pump parts.

How do you bleed air out of a hydraulic system?

Releasing the Air Once you have partially closed the cylinder, you can open the bleed valve at the top, providing an escape for the air that has become trapped inside. Leave this valve open until hydraulic fluid flows from the valve, indicating the air has been fully released.

How do you get air out of hydraulic fluid?

For dissolved air, you can remove it by raising the temperature of the fluid until the air is released. This should only be done if absolutely necessary as hydraulic oil will normally tend to be at least 10% dissolved air.

Do you have to bleed air out of hydraulic system?

Air in your hydraulic lines can eventually cause damage to the entire system, so it's a good idea to bleed the lines once in a while, or if you suspect air was caught.

Can a hydraulic system get air locked?

Even air that has become trapped in oil will usually get transported back to the reservoir at some point. However, bleeding air from a hydraulic system can speed up this process. It's common knowledge that air trapped in a system can cause mechanical damage and lead to erratic operation.

Can air get trapped in hydraulic system?

Trapped air in hydraulic systems can adversely impact performance because air is compressible and hydraulic fluid is not. This means that the density and volume of hydraulic fluid remain the same with changes in pressure.

Why does my hydraulic cylinder bleed down?

Leaks generally occur when the piston seals, holding valve, or rod seals wear out or are compromised due to various reasons. One cause of hydraulic cylinder drift is contaminated hydraulic fluid, which can damage seals and/or sealing surfaces.

What causes low pressure in hydraulic system?

Worn or Damaged Components: A hydraulic system is interlinked with many connected components like pumps, valves, motors, cylinders, and more. Damage or wear to these components including leakage will affect system pressure.

What causes air bubbles in hydraulic oil?

When hydraulic oil temperature increases or static pressure decreases, air solubility is reduced and bubbles can form within the fluid. This release of dissolved air is known as gaseous cavitation.

What does bubbles in hydraulic fluid mean?

It usually forms when hydraulic fluid is mixed with air from a free surface. As the air becomes trapped in the fluid it forms bubbles of air. As those bubbles begin to rise to the surface of the hydraulic fluid they group together to form foam.

How does air get into a hydraulic cylinder?

This is usually the result of a faulty or incorrectly adjusted load-control valve. Most hydraulic cylinder rod-seals are not designed to keep air out! When this happens, a negative pressure develops in the rod side of the hydraulic cylinder, which can result in air being drawn into the cylinder past its rod seal.

How do you test air in a hydraulic system?

Air in the hydraulic fluid makes an alarming banging or knocking noise when it compresses and decompresses, as it circulates through the system. Other symptoms include foaming of the fluid and erratic actuator movement.

STEP 0: Read your manual

I know, obvious, but needs to be said. The steps below are general to many models. You will want to read your make and models manual for exact details specific to your machine.

STEP 1: Check for Hydraulic Fuel Leakage

I’m a fan of cardboard.

STEP 2: Fill hydraulic Fluid Reservoir

First, don’t forget there is direct correlation between your machines working power and the hydraulic fluid level. Hydraulic fluid is really the main component in your log splitter. Don’t let the level get low and check it frequently.

STEP 3: Air Removal from a Hydraulic Cylinder

Done filling your hydraulic fluid? Wait! You are not done yet. You must bleed or purge the trapped air from the cylinder. To do that you need to extend the piston rod to its maximum length and remove the oil filling plug.

STEP 4: Clean log splitter regularly

Consider choosing a self-cleaning hydraulic log splitter. If you do not have one, be sure to clean your machine on a regular basis. Cleaning involves removing oil, grease, and debris. Also, clean debris around the machine so nothing can get trapped inside the machine. Always remember to turn off the machine before performing the cleaning work.

STEP 5: Sharpen the blades

If you notice any sign of dullness or spot on the edge of the blade, sharpen it using a coarse metal file first. To reform the sharp point of the blade, use the coarse file to sharpen the sides. Then finish the process by using a metal file along with the edge of the blade.

STEP 6: Store in a dry place

You need to store your log splitter in a dry place to prevent damage from water and rust. A shed or garage is a very good choice for keeping your log splitter dry throughout the year if the garage stays dry for rest of the year! However, using a waterproof cover to protect your log splitter is also a good idea.
