The Volvo EC 330B is a robust, versatile excavator used in a variety of construction and excavation tasks. Operators often face the challenge of adapting to different control patterns depending on the machine model, site requirements, or personal preferences. The ability to switch between different control patterns can significantly impact the ease and efficiency with which the operator can maneuver the machine.
In this article, we will dive into the process of switching control patterns on the Volvo EC 330B excavator, focusing on the importance of control types, the steps involved in switching, and the practical implications of this process. Additionally, we’ll look at some related tips for machine operation and real-world examples of operators who have navigated this control system change.
Understanding Excavator Control Patterns
Before diving into how to switch control patterns, it’s essential to understand the basic types of controls used in excavators:
1. ISO Controls (or SAE Controls)
ISO control pattern, also referred to as SAE controls, is the most commonly used control layout for excavators, especially in the United States. In this setup:
The JRB control pattern is a variation of the ISO controls, where:
Why Switch Control Patterns?
There are a few reasons why an operator might want to switch control patterns:
1. Personal Preference
Different operators may find one control pattern more intuitive or comfortable than the other. For example, an operator with previous experience on a John Deere excavator may prefer the JRB pattern, while someone accustomed to Volvo’s ISO layout might prefer the ISO controls.
2. Job Requirements
On larger job sites, multiple machines may be operating together. If a machine is being shared between operators who have different control pattern preferences, being able to switch the control type can improve efficiency and reduce the time spent on adapting to a new machine.
3. Operator Training
For training purposes, switching between different control patterns allows the operator to gain experience with both types of controls, giving them more flexibility in their skills. This can be especially useful when an operator is preparing to work on different types of equipment across job sites.
Steps to Switch Control Patterns on the Volvo EC 330B
Switching control patterns on the Volvo EC 330B can be achieved relatively easily. Here’s a step-by-step guide on how to perform this task:
Step 1: Locate the Control Pattern Selector
On the Volvo EC 330B, the control pattern selector switch is typically located near the operator’s seat or console area. It’s important to consult the user manual for the exact location, as different excavators may have slightly different setups.
Step 2: Ensure the Machine is at Idle
Before making any changes to the control pattern, always ensure the machine is idling. This is crucial for safety and to prevent any sudden movements that could occur if adjustments are made while the machine is active.
Step 3: Flip the Control Pattern Selector Switch
Once you’ve located the selector switch, flip it to the desired position. The switch will typically have clear markings to indicate which control pattern it corresponds to. On some machines, this switch can be flipped to either the ISO or JRB control setting.
Step 4: Test the New Settings
After switching the control pattern, it’s essential to test the new settings to make sure the machine’s controls are working as expected. Start by running the machine through basic functions like lifting the boom, tilting the bucket, and rotating the swing. Pay close attention to the feel of the controls to confirm they respond in the way you expect.
Step 5: Adjusting the Seat and Armrest (If Necessary)
In some cases, changing control patterns might affect how comfortably you operate the machine. Make sure your seat and armrests are adjusted for optimal comfort and ergonomics, especially if you’re switching to a control pattern you’re less familiar with.
Practical Implications of Switching Control Patterns
While switching between different control patterns can improve comfort and efficiency, operators should also be aware of some practical considerations:
1. Familiarity with the Control Layout
Switching between control layouts requires a bit of practice. If an operator is switching between ISO and JRB patterns, it can take time to adapt to the different joystick movements. It’s advisable for operators to practice on open ground or in a safe environment before engaging in complex tasks.
2. Machine Calibration
Ensure that after switching control patterns, the machine is properly calibrated. If the controls are unresponsive or difficult to manage after switching, it might indicate a calibration issue. Consult the manual for the Volvo EC 330B or contact a technician to ensure proper calibration.
3. Wear and Tear on Controls
Frequent switching between control patterns can cause wear on the control system, especially if the switch is operated too forcefully or too often. To minimize this, only switch when necessary and always follow the manufacturer’s instructions for use.
Real-World Experiences of Switching Control Patterns
Operators who have used the Volvo EC 330B and other similar excavators often share their experiences with control pattern switching. For instance, one operator noted that switching to the JRB pattern helped them become more comfortable when operating different brands of machines on the same site. While they initially struggled with the new control setup, after some time, they found that switching control patterns provided more versatility in their work.
On the flip side, another operator mentioned that switching control patterns in the middle of a job can be tricky if the operator isn’t fully familiar with both layouts. In this case, they recommended always testing the new control settings before using the machine for more complex tasks, such as trenching or lifting heavy loads.
Maintaining the Control System
Like any part of the machine, the control system requires regular maintenance to ensure it functions smoothly. Here are a few tips to maintain the Volvo EC 330B control system:
Switching between control patterns on the Volvo EC 330B excavator can enhance both comfort and versatility for operators. Whether due to personal preference, job requirements, or training, the ability to toggle between ISO and JRB controls allows operators to get the most out of their machines. However, it’s important to practice, test the new settings, and perform routine maintenance to ensure smooth operation. By understanding the control patterns, troubleshooting common issues, and properly maintaining the control system, operators can improve their efficiency and safety on the job site.

1. ISO Controls (or SAE Controls)
ISO control pattern, also referred to as SAE controls, is the most commonly used control layout for excavators, especially in the United States. In this setup:
- The left joystick controls the arm (boom) and the bucket (dipper).
- The right joystick controls the swing of the excavator and the bucket tilt.
The JRB control pattern is a variation of the ISO controls, where:
- The left joystick controls the bucket and swing functions.
- The right joystick controls the boom and dipper.
