Predator 20 Ton Log Splitter Troubleshooting: 5 Fuel Fixes
Fuel problems are among the most common reasons a log splitter fails. They’re often simple to diagnose and fix, saving you time and money on repairs. I’ve spent years working with various log splitters, including the Predator 20 Ton, and I’ve learned that preventative maintenance and understanding basic fuel system principles can go a long way.
1. Understanding the Basics: Fuel Systems and Key Terms
Before diving into specific fixes, let’s cover the fundamentals. Understanding these concepts will make troubleshooting much easier.
- Fuel System Components: A typical small engine fuel system, like the one on the Predator 20 Ton, consists of:
- Fuel Tank: Holds the gasoline.
- Fuel Line: Carries fuel from the tank to the carburetor.
- Fuel Filter: Removes contaminants from the fuel.
- Fuel Shut-Off Valve: Allows you to stop fuel flow to the carburetor.
- Carburetor: Mixes fuel and air for combustion.
- Air Filter: Prevents dirt and debris from entering the carburetor.
- Green Wood vs. Seasoned Wood: This distinction is crucial for firewood preparation. Green wood has a high moisture content (often 50% or more), making it difficult to split and burn. Seasoned wood has been air-dried, reducing moisture content to 20% or less. The type of wood you’re splitting affects the strain on your log splitter.
- Ethanol in Fuel: Most gasoline sold today contains ethanol. Ethanol can absorb water, leading to fuel separation and corrosion in small engines. This is a major cause of fuel-related problems.
- Fuel Stabilizers: Additives that prevent fuel from degrading and protect the fuel system from ethanol-related damage.
My Experience: I once had a Predator 20 Ton that refused to start after sitting unused for a few months. I initially suspected a major issue, but after checking the fuel, I found it had separated due to ethanol. A simple fuel system cleaning and the use of fuel stabilizer solved the problem.
2. Fix #1: Stale Fuel
Stale fuel is a common culprit, especially if the log splitter has been sitting idle for an extended period. Gasoline can degrade in as little as 30 days, leading to starting problems and poor performance.
- Symptoms of Stale Fuel:
- Difficulty starting.
- Rough idling.
- Lack of power.
- Fuel smells “varnished” or different than usual.
- Step-by-Step Solution:
- Drain the Fuel Tank: Disconnect the fuel line from the carburetor (ensure the fuel shut-off valve is closed first!). Place a container under the fuel line to catch the old fuel. Open the fuel shut-off valve to drain the tank completely. Dispose of the old fuel properly (check your local regulations for disposal guidelines).
- Inspect the Fuel Tank: Check for sediment, rust, or water. If present, clean the tank thoroughly. You can use a clean rag and a long screwdriver to wipe out the tank. For heavy rust, consider using a fuel tank cleaner.
- Refill with Fresh Fuel: Use fresh, high-quality gasoline with an octane rating of 87 or higher. Add a fuel stabilizer to prevent future degradation. I recommend a fuel stabilizer specifically designed for small engines, such as STA-BIL or Sea Foam.
- Prime the Carburetor: Most small engines have a primer bulb. Press the primer bulb several times to draw fresh fuel into the carburetor.
- Attempt to Start: Follow the starting procedure outlined in your Predator 20 Ton Log Splitter owner’s manual.
