In this article, we will delve into the possible causes of start-up problems and air heater malfunctions on the Takeuchi TB135. By addressing these issues proactively, operators can ensure their equipment runs smoothly and avoid costly repairs.
Identifying Start-Up Issues
Start-up problems are one of the most frustrating issues any operator can face. On the Takeuchi TB135, several factors can contribute to difficulties when trying to start the engine:
If you encounter starting problems with the Takeuchi TB135, here’s a step-by-step guide to diagnose and resolve the issue:
Step 1: Check the Battery
The first thing to check when your TB135 won’t start is the battery. Ensure it is charged and in good condition. If the battery is old, it may not hold a charge and will need to be replaced. Clean the battery terminals of any corrosion and ensure they are tightly connected. If you’re operating in cold temperatures, consider using a battery heater to help maintain charge.
Step 2: Inspect the Fuel System
Next, inspect the fuel system for any signs of clogging or contamination. Start by checking the fuel filter. A clogged fuel filter can block the flow of fuel to the engine, causing starting issues. Replace the filter if it appears dirty or old. Also, check for air in the fuel lines. If you suspect air in the lines, bleed the system to remove it.
Step 3: Test the Ignition System
A faulty ignition system can also cause the engine to fail to start. Inspect the ignition switch, wiring, and relays for any signs of wear or damage. If you have an electric starter motor, ensure that it is functioning properly by testing it. Replace any faulty components in the ignition system.
Step 4: Examine the Glow Plugs
During cold weather, the glow plugs play an essential role in engine start-up. Test the glow plugs using a multimeter to ensure they are working properly. If a glow plug is faulty, replace it to ensure optimal starting performance.
Step 5: Check for Codes or Warnings
Many modern excavators, including the Takeuchi TB135, come equipped with diagnostic systems that can provide error codes or warnings if there is an issue. Use a diagnostic tool to scan the machine for any stored codes that might indicate a specific problem with the starting system.
Troubleshooting Air Heater Issues
In addition to start-up problems, some operators of the TB135 have reported issues with the air heater, which is vital for warming up the engine in cold temperatures. If the air heater isn't functioning correctly, the engine might struggle to start, especially in chilly or freezing conditions. Here are some potential causes and solutions for air heater problems:
If you are having issues with the air heater on the TB135, follow these steps to troubleshoot the problem:
Step 1: Inspect the Heater Relay
Check the air heater relay for signs of damage. If you suspect it is faulty, test it using a multimeter to ensure it is sending power to the air heater. If necessary, replace the relay with a new one.
Step 2: Test the Heater Element
Use a multimeter to check the resistance of the heater element. If it shows an open circuit or very high resistance, the element may be damaged and needs replacing.
Step 3: Examine Wiring and Connections
Inspect the wiring and connections leading to the air heater. Look for any frayed wires, damaged connectors, or corrosion. Clean the terminals and ensure all connections are tight and secure.
Step 4: Check Fuel Supply
If the air heater runs on fuel, check the fuel lines for clogs or leaks. If the fuel lines are clear, make sure the fuel filter is clean and the fuel pump is working properly. If there are any obstructions in the fuel line, clear them before attempting to use the heater again.
Conclusion
The Takeuchi TB135 is a versatile and reliable mini excavator, but like any piece of equipment, it can experience starting issues and malfunctions in the air heater system. By following the troubleshooting steps outlined in this article, you can quickly identify and resolve the most common problems that affect starting and air heater performance.
For operators working in cold climates, it is essential to pay close attention to the condition of the battery, glow plugs, and air heater, as these components are critical for ensuring smooth start-ups. Regular maintenance and inspection can help prevent many of these issues from occurring, keeping your TB135 running efficiently for years to come.
Remember, if you are unable to resolve the issue yourself or if the problem persists, don’t hesitate to contact a qualified technician who is familiar with Takeuchi equipment for further assistance.

Identifying Start-Up Issues
Start-up problems are one of the most frustrating issues any operator can face. On the Takeuchi TB135, several factors can contribute to difficulties when trying to start the engine:
- Battery Problems: A weak or discharged battery is one of the most common causes of starting issues. In cold weather conditions, the battery may lose charge, making it difficult to turn over the engine. Additionally, battery terminals may corrode, preventing proper electrical contact.
- Fuel System Issues: Clogged fuel filters, air in the fuel lines, or a dirty fuel system can also prevent the engine from starting. If the engine isn't getting enough fuel, it will fail to start or run improperly.
- Ignition System Failures: Problems with the ignition switch, starter motor, or relays can cause intermittent or complete failure to start the machine.
- Glow Plug Problems: In cold weather, diesel engines rely on glow plugs to help start the engine. A malfunctioning glow plug or faulty relay can lead to long cranking times or failure to start altogether.
