Common Causes of the Flashing Line Filter Warning Light
Several factors could cause the line filter warning light to flash on the Takeuchi TL140. Let’s break down the most common causes:
- Clogged or Dirty Line Filter
Over time, hydraulic filters can become clogged with dirt, debris, and other contaminants, especially when operating in dusty environments or using the machine in harsh conditions. A clogged filter restricts the flow of hydraulic fluid, causing the system to work harder and potentially triggering the warning light.- Solution: Inspect the line filter and replace it if it’s clogged or dirty. It’s recommended to replace the hydraulic filter every 500 hours of operation or as specified in the owner’s manual. Regular maintenance and filter changes can help prevent this issue from occurring in the future.

- Low Hydraulic Fluid Levels
The flashing warning light could also indicate that the hydraulic fluid level is low. Insufficient fluid can cause the hydraulic system to operate under pressure, which can result in system damage and the warning light being triggered.- Solution: Check the hydraulic fluid level and top it off if necessary. Be sure to use the correct type of fluid, as specified by the manufacturer. If the fluid is consistently low, check for any leaks in the hydraulic system.

- Contaminated Hydraulic Fluid
Hydraulic fluid is essential for the proper functioning of the loader’s hydraulic system. If the fluid becomes contaminated with water, dirt, or other particles, it can affect the filter’s ability to trap debris, causing the system to become sluggish and inefficient.- Solution: Inspect the hydraulic fluid for signs of contamination, such as discoloration or a milky appearance. If contamination is suspected, drain the system, replace the filter, and refill the system with clean hydraulic fluid. Additionally, ensure that you are using the right type of fluid for your machine’s operating conditions.

If contamination is suspected, drain the system, replace the filter, and refill the system with clean hydraulic fluid. Additionally, ensure that you are using the right type of fluid for your machine’s operating conditions.
- Hydraulic System Pressure Issues
If there’s a problem with the pressure in the hydraulic system, such as a malfunctioning pump or relief valve, it can cause the filter warning light to flash. These pressure issues could also impact the loader’s performance, causing erratic movements or an inability to lift or move loads properly.- Solution: Use a hydraulic pressure gauge to check the pressure in the system. If the pressure is outside of the manufacturer’s specified range, you may need to inspect or replace the hydraulic pump, relief valve, or other related components.
