How to Locate and Use the ISO/SAE Control Pattern Switch on a Terex TC50 Mini Excavator

[MikePhua]

Operating a mini excavator efficiently requires familiarity with its control patterns. The Terex TC50, a compact and versatile machine, offers operators the ability to switch between ISO and SAE control patterns. This flexibility allows for a more personalized and comfortable operating experience. However, locating the control pattern switch can be challenging, especially for new owners.
Understanding ISO and SAE Control Patterns
Before delving into the specifics of the Terex TC50, it's essential to understand the two primary control patterns:

• ISO Pattern: Commonly referred to as "excavator controls," this pattern is widely used in North America. In this configuration, the left joystick controls the boom and swing, while the right joystick manages the stick and bucket.
  
• SAE Pattern: Often called "backhoe controls," this pattern is prevalent in the United States. Here, the left joystick controls the boom and bucket, while the right joystick manages the stick and swing.
  

Switching between these patterns allows operators to choose the configuration they are most comfortable with, enhancing control and efficiency.
Locating the Control Pattern Switch on the Terex TC50
For the 2007 Terex TC50 model, the control pattern switch is typically located near the operator's seat or on the control panel. However, some users have reported difficulty finding this switch. In such cases, it's advisable to consult the operator's manual for specific instructions. If the manual is unavailable, contacting a Terex dealer or service center can provide guidance.
Step-by-Step Guide to Switching Control Patterns

1. Ensure the Excavator is Turned Off: For safety reasons, always turn off the machine before making adjustments.
   
2. Locate the Control Pattern Switch: As mentioned, this switch is usually near the operator's seat or on the control panel.
   
3. Adjust the Switch: Flip or toggle the switch to change the control pattern from ISO to SAE or vice versa.
   
4. Verify the Change: After adjusting, start the machine and test the controls to ensure the pattern has been switched correctly.
   

Alternative Method: Manual Switching
If the Terex TC50 does not have an integrated control pattern switch, the pattern can be changed manually by swapping the hydraulic hoses connected to the joysticks. This process involves:

• Identifying the Hydraulic Hoses: Locate the hoses connected to the joystick control valves.
  
• Switching the Hoses: Carefully disconnect and swap the hoses between the left and right joysticks.
  
• Testing the Controls: After making the switch, test the machine to ensure the controls function as desired.
  

It's crucial to perform this procedure with caution to avoid damaging the hydraulic system. If unsure, it's recommended to seek assistance from a professional technician.
Conclusion
The ability to switch between ISO and SAE control patterns on the Terex TC50 mini excavator enhances operational flexibility and comfort. While the integrated control pattern switch is typically located near the operator's seat or on the control panel, some models may require manual switching of hydraulic hoses. Always prioritize safety and consult the operator's manual or a professional technician if needed.
