Hey there! As a supplier of Wheel Excavator Diggers, I know how important it is to keep these machines in top - notch condition. One of the key aspects of maintenance is checking the hydraulic oil level. In this blog, I'll walk you through the process step by step.
First off, let's understand why checking the hydraulic oil level is such a big deal. The hydraulic system in a wheel excavator digger is like the heart of the machine. It's responsible for powering various functions such as the boom movement, bucket operation, and even the steering in some cases. If the hydraulic oil level is too low, it can lead to a bunch of problems. The system might not work as smoothly, and in the worst - case scenario, it could cause serious damage to the hydraulic components. On the other hand, if the oil level is too high, it can also cause issues like overheating and excessive pressure in the system.


Now, before you start checking the hydraulic oil level, you need to make sure the machine is in a safe and stable position. Park the wheel excavator digger on a flat surface and turn off the engine. Let the machine cool down for a bit, especially if it has been running for a while. This is important because hot oil can expand, and you might get an inaccurate reading if you check it right after the machine has been in use.
The next step is to locate the hydraulic oil reservoir. In most wheel excavator diggers, the reservoir is usually located near the engine or in a compartment on the side of the machine. It's often a large, see - through container with markings on the side indicating the minimum and maximum oil levels. Some reservoirs might have a dipstick instead.
If your wheel excavator digger has a see - through reservoir, it's pretty straightforward. Just look at the level of the oil inside the container. The oil should be between the minimum and maximum markings. If it's close to or below the minimum mark, it's time to add some hydraulic oil.
For those machines with a dipstick, here's what you do. First, pull out the dipstick and wipe it clean with a rag. Then, re - insert the dipstick all the way back into the reservoir. Make sure it goes in fully. After that, pull it out again and check the oil level on the dipstick. Just like with the see - through reservoir, the oil should be between the minimum and maximum markings. If it's low, you'll need to add more oil.
When adding hydraulic oil, you need to use the right type of oil specified in the machine's manual. Different wheel excavator diggers might require different grades of hydraulic oil, so it's crucial to get it right. You can use a funnel to pour the oil into the reservoir slowly. Keep an eye on the level as you pour, and stop when the oil reaches the appropriate level.
Now, let's talk about some common mistakes to avoid when checking the hydraulic oil level. One of the biggest mistakes is not checking the oil level regularly. Make it a part of your routine maintenance schedule. Another mistake is using the wrong type of hydraulic oil. Using the wrong oil can lead to poor performance and even damage to the hydraulic system.
