Wood chipper not chipping, what am I doing wrong?

Top Reasons Your Industrial Wood Chipper Isn’t Working & How to Fix It

Is your industrial wood chipper not performing as expected? This can be frustrating, especially when you rely on it for high-efficiency wood processing. Let’s fix that together.

Wood chippers stop working due to overfeeding, dull blades, improper materials, or power issues. Troubleshooting these problems step-by-step can quickly restore your chipper’s functionality.

Understanding these common issues and how to address them will save you time, money, and frustration. Let’s dive into the main reasons and solutions for a non-functional wood chipper.

Are you overfeeding your wood chipper?

Overfeeding is a common mistake that many users make without realizing it. It can overwhelm the machine and cause it to stop chipping altogether.

To avoid overfeeding, always adhere to your wood chipper’s capacity limits. Feed materials gradually to prevent blockages or unnecessary strain on the machine.

Overfeeding can damage the internal components of the machine over time. Check your user manual for the recommended maximum feed size and adjust your operations accordingly. If you notice frequent clogs, it might be time to inspect the feed chute for debris buildup.

Could dull or damaged blades be the issue?

Your wood chipper’s blades are crucial for its performance. Over time, they can become dull or damaged, leading to inefficient chipping or complete failure.

Inspect the blades regularly for signs of wear. Sharpen or replace them as needed to maintain optimal performance and ensure clean, precise cuts.

Blades should be checked weekly or after heavy use. If chips are uneven or the wood appears shredded rather than cleanly cut, this is a clear sign the blades need attention. Use high-quality replacement blades and follow proper installation procedures to ensure safety and efficiency.

Are you using improper materials?

Wood chippers are designed for specific types of materials. Feeding inappropriate items, like overly wet wood or non-wood debris, can damage the machine.

Stick to the recommended materials in your chipper’s manual. Avoid feeding wet, rotting, or overly dense wood to prevent jams and damage.

Improper materials can clog the turbine or the shredding chamber. If you suspect a jam, turn off the machine immediately and allow it to cool before inspecting or clearing the blockage. Always wear protective gear and follow safety guidelines during maintenance.

Is your power source or fuel running low?

A lack of sufficient power or fuel is another common reason wood chippers stop working. This is especially true for larger industrial models that require consistent energy input.

Check that your machine has enough fuel or is properly connected to a reliable power source. Low power can hinder performance or prevent the machine from starting.

For gas-powered models, ensure the fuel is fresh and topped off. For electric models, inspect the power cords for damage and ensure they’re securely connected. Keeping the power supply in top condition will prevent sudden interruptions during operation.

How can you safely clear jams and inspect the machine?

Jams can happen even with proper use, especially if debris accumulates in the shredding chamber. Clearing these blockages safely is critical.

Turn off the machine and disconnect it from the power source before attempting to clear a jam. Use tools, not hands, to remove debris.

Inspect the shredding chamber and turbine for stuck materials. Use a wooden stick or similar tool to gently dislodge clogs. Avoid using metal tools that could damage internal components. Once cleared, carefully restart the machine and test its functionality.

What preventative measures can you take for optimal performance?

Regular maintenance is key to keeping your wood chipper running smoothly. Neglecting care can lead to frequent breakdowns and costly repairs.

Clean the machine after each use, sharpen blades regularly, and check for loose parts. Routine maintenance ensures consistent performance and extends the lifespan of your equipment.

Develop a maintenance schedule that includes daily cleaning, weekly blade inspections, and monthly lubrication of moving parts. Store the machine in a dry, sheltered location to protect it from the elements. For detailed maintenance tips, visit our blog.
