Excavators like the SK135SR-1 are vital pieces of machinery in construction, mining, and other heavy-duty industries. Known for their power, precision, and versatility, these machines often face wear and tear due to continuous use. One of the common issues that operators might encounter is arm swing problems. If the arm on the SK135SR-1 isn’t swinging correctly or is exhibiting unusual behavior, it could be a sign of underlying mechanical issues that need immediate attention.
This article will explore the possible causes of arm swing problems in the SK135SR-1, provide a step-by-step troubleshooting guide, and offer solutions to get your machine back to its optimal performance.
Common Causes of Arm Swing Problems in the SK135SR-1
The arm swing function in excavators like the SK135SR-1 is powered by the hydraulic system, which consists of various components that work together to achieve smooth movement. Any issue in the hydraulic, mechanical, or electrical systems can affect the arm’s performance. Here are the most common reasons behind arm swing problems:
1. Low Hydraulic Fluid Levels
One of the most common causes of arm swing problems is low hydraulic fluid levels. If the fluid levels are too low, the hydraulic pump may struggle to provide enough pressure to operate the arm, leading to slow or jerky movements.
Leaks in the hydraulic system can also cause a lack of pressure, which leads to the arm swing malfunctioning. Leaking hoses, seals, or fittings can allow air into the system or cause fluid loss, impacting the function of the arm.
If the hydraulic pump or valves controlling the arm swing are faulty, the arm may not move correctly. These components are responsible for directing hydraulic fluid to the appropriate cylinders, and any malfunction can result in sluggish or erratic arm movement.
The arm swing motor is a crucial component for arm movement. If the motor becomes worn or damaged, it may not provide enough force to move the arm. This can result in a weak or slow arm swing.
Hydraulic filters are designed to remove contaminants from the fluid, but if they become clogged or dirty, it can restrict the flow of hydraulic fluid. This can lead to reduced power in the system, affecting the arm swing.
The control valve regulates the flow of hydraulic fluid to various parts of the excavator, including the arm swing mechanism. If the control valve is malfunctioning, it could lead to issues with arm movement, such as unresponsiveness or erratic motion.
If your SK135SR-1 is experiencing arm swing problems, here’s a step-by-step guide to troubleshoot and fix the issue:
Step 1: Check Hydraulic Fluid Levels and Quality
The first step in troubleshooting arm swing issues is to check the hydraulic fluid levels. Low fluid levels can lead to a loss of pressure in the hydraulic system, affecting the arm’s movement.
Next, inspect the hydraulic lines for leaks. Leaks can result in a loss of pressure, which will impact the performance of the arm swing.
The hydraulic pump and valves are responsible for directing fluid to the arm swing motor. If they’re malfunctioning, the arm may not move as expected.
The arm swing motor is the heart of the system. If the motor is worn or damaged, it will affect the arm’s movement.
Clogged or dirty hydraulic filters can restrict fluid flow and cause power loss in the arm swing system.
Finally, inspect the control valve that regulates the hydraulic fluid flow to the arm swing motor. A malfunctioning valve can cause erratic or unresponsive arm movement.
Preventive maintenance is key to avoiding arm swing problems in the future. Here are some tips to keep your SK135SR-1 in top condition:
Arm swing problems in the SK135SR-1 can be caused by a variety of factors, from low hydraulic fluid levels to faulty components. By following the troubleshooting steps outlined in this article, you can identify and resolve the issue before it leads to significant downtime or expensive repairs.
Regular maintenance and timely inspections are essential to keeping your excavator running smoothly and ensuring that it continues to perform at its best. If the issue persists or is more complex than you can handle, consulting a professional technician will help restore the full functionality of your machine.

1. Low Hydraulic Fluid Levels
One of the most common causes of arm swing problems is low hydraulic fluid levels. If the fluid levels are too low, the hydraulic pump may struggle to provide enough pressure to operate the arm, leading to slow or jerky movements.
- Solution: Check the hydraulic fluid levels and top them up if needed. Always ensure that you’re using the recommended type of hydraulic fluid to maintain optimal performance.
Leaks in the hydraulic system can also cause a lack of pressure, which leads to the arm swing malfunctioning. Leaking hoses, seals, or fittings can allow air into the system or cause fluid loss, impacting the function of the arm.
- Solution: Inspect the hydraulic lines, hoses, and fittings for any signs of leaks. Replace any damaged components, and make sure all fittings are tight and secure.
If the hydraulic pump or valves controlling the arm swing are faulty, the arm may not move correctly. These components are responsible for directing hydraulic fluid to the appropriate cylinders, and any malfunction can result in sluggish or erratic arm movement.
- Solution: Have the hydraulic pump and valves inspected by a professional technician. If necessary, replace the faulty components or have them repaired.
The arm swing motor is a crucial component for arm movement. If the motor becomes worn or damaged, it may not provide enough force to move the arm. This can result in a weak or slow arm swing.
- Solution: Inspect the arm swing motor for signs of wear or damage. If the motor is malfunctioning, it may need to be replaced or repaired by a professional.
Hydraulic filters are designed to remove contaminants from the fluid, but if they become clogged or dirty, it can restrict the flow of hydraulic fluid. This can lead to reduced power in the system, affecting the arm swing.
- Solution: Clean or replace the hydraulic filters regularly to maintain optimal fluid flow and prevent contamination of the hydraulic system.
The control valve regulates the flow of hydraulic fluid to various parts of the excavator, including the arm swing mechanism. If the control valve is malfunctioning, it could lead to issues with arm movement, such as unresponsiveness or erratic motion.
- Solution: Inspect the control valve for any issues. If the valve is sticking, worn out, or damaged, it may need to be repaired or replaced.
If your SK135SR-1 is experiencing arm swing problems, here’s a step-by-step guide to troubleshoot and fix the issue:
Step 1: Check Hydraulic Fluid Levels and Quality
The first step in troubleshooting arm swing issues is to check the hydraulic fluid levels. Low fluid levels can lead to a loss of pressure in the hydraulic system, affecting the arm’s movement.
- How to do it: Locate the hydraulic fluid reservoir and check the level. If the fluid is low, top it up with the recommended fluid. Also, inspect the fluid’s quality. If it appears dirty or contaminated, it’s time to replace it.
