Wood Splitter Tool Guide: 7 Pro Tips for Hydraulic Maintenance
Hydraulic wood splitters are essential for anyone who regularly processes firewood. Their power and efficiency can transform a back-breaking task into a manageable one. However, like any piece of machinery, they require regular maintenance to perform optimally and avoid costly repairs. I’ve spent years working with these machines, and I’ve learned firsthand what works and what doesn’t. These seven pro tips are designed to help you keep your hydraulic wood splitter in top condition.
1. The Vital Fluid: Hydraulic Oil Checks and Changes
Hydraulic oil is the lifeblood of your wood splitter. It transmits the power that drives the ram and splits the wood. Dirty or low oil can lead to reduced splitting force, sluggish performance, and ultimately, damage to the pump and other components.
Why it matters: Hydraulic oil not only transmits power but also lubricates internal parts and dissipates heat. Contaminated oil loses its lubricating properties and can introduce abrasive particles into the system, causing wear.
How to check the oil:
- Frequency: Check the oil level before each use.
- Location: The oil reservoir is usually located near the pump and has a dipstick or sight glass.
- Procedure:
- Ensure the splitter is on level ground.
- Clean the area around the dipstick or sight glass to prevent debris from entering the reservoir.
- Remove the dipstick, wipe it clean, and reinsert it fully.
- Remove the dipstick again and check the oil level against the “full” mark.
- If using a sight glass, the oil level should be visible within the marked range.
- What to look for: The oil should be clear and free of contaminants. Milky or foamy oil indicates the presence of water, while dark or gritty oil signifies contamination.
How to change the oil:
- Frequency: Change the hydraulic oil every 100-200 hours of use, or at least once a year. This frequency depends on usage and environmental conditions. If you’re splitting a lot of green wood, which introduces more moisture, you might need to change it more often.
- Tools needed:
- Wrench (size will vary depending on the drain plug)
- Oil drain pan
- Funnel
- New hydraulic oil (type specified in your owner’s manual)
- Clean rags
- Procedure:
- Warm up the wood splitter by running it for a few minutes. This will help the oil flow more easily.
- Turn off the engine or disconnect the power source.
- Locate the drain plug on the bottom of the oil reservoir.
- Position the drain pan under the drain plug.
- Carefully remove the drain plug and allow the oil to drain completely.
- Once the oil has drained, replace the drain plug and tighten it securely.
- Locate the fill port on the oil reservoir.
- Using a funnel, add new hydraulic oil to the reservoir until it reaches the “full” mark on the dipstick or sight glass.
- Start the engine or connect the power source and run the splitter for a few minutes, cycling the ram back and forth several times.
- Turn off the engine or disconnect the power source and check the oil level again. Add more oil if needed.
- Oil Type: Always use the hydraulic oil type specified in your owner’s manual. Using the wrong type of oil can damage the pump and other components. AW32 or AW46 are common choices, but confirm the correct viscosity for your specific model. I’ve seen people use motor oil in a pinch, and while it might work temporarily, it’s a recipe for disaster in the long run.
- Disposal: Dispose of used hydraulic oil properly at a recycling center or hazardous waste collection facility. Never pour it down the drain or onto the ground.
Story Time: I once had a friend who ignored the oil changes on his splitter. He figured, “It’s just oil, how much difference can it make?” After a few seasons of hard use, his pump seized up, requiring a costly replacement. He learned the hard way that regular maintenance is far cheaper than major repairs.
Takeaway: Regular hydraulic oil checks and changes are crucial for maintaining the performance and longevity of your wood splitter.
2. Filter Finesse: Keeping the System Clean
Hydraulic filters are designed to remove contaminants from the hydraulic oil, preventing them from circulating through the system and causing wear.

Types of Hydraulic Filters:
- Spin-on filters: These are the most common type and are easy to replace.
- In-line filters: These are located within the hydraulic lines and require more effort to replace.
- Suction filters: These are located in the oil reservoir and protect the pump from large debris.
How to check the filter:
- Frequency: Check the filter every 50 hours of use, or more often if you are working in a dusty or dirty environment.
- Procedure:
- Locate the hydraulic filter. Consult your owner’s manual if you are unsure of its location.
- Visually inspect the filter for damage or leaks.
- If the filter is a spin-on type, check for any signs of bulging or distortion.
- Some filters have a pressure gauge that indicates when the filter needs to be replaced.
How to replace the filter:
- Tools needed:
- Wrench (size will vary depending on the filter)
- Oil drain pan
- New hydraulic filter (correct type for your machine)
- Clean rags
- Procedure:
- Turn off the engine or disconnect the power source.
- Position the drain pan under the filter.
- Loosen the filter with a wrench and unscrew it by hand.
- Allow any remaining oil to drain into the pan.
- Lubricate the rubber gasket on the new filter with clean hydraulic oil.
- Screw the new filter onto the filter housing by hand until the gasket makes contact.
- Tighten the filter according to the manufacturer’s instructions (usually about 1/2 to 3/4 of a turn after contact).
- Start the engine or connect the power source and check for leaks.
Pro Tip: When replacing the filter, always use a filter that is specifically designed for hydraulic systems. Automotive oil filters are not suitable for this application.
My Experience: I once used a generic filter on my splitter to save a few bucks. Big mistake. It clogged up quickly, and the splitter started losing power. I ended up having to replace the filter and flush the entire hydraulic system. Lesson learned: use the right filter!
