how to check hydraulic oil level on hitachi excavator

Hitachi excavators are efficient and reliable machines used for construction, mining, and other heavy-duty operations. The hydraulic system is a critical part of the excavator, and it requires regular maintenance to keep it working optimally. Checking the hydraulic oil level is one of the most important tasks that you need to perform to ensure the longevity and performance of your excavator. In this article, we will look at how to check the hydraulic oil level on a Hitachi excavator.

Step 1: Safety first

Before you start checking the hydraulic oil level, it is essential to take some safety precautions. Make sure the excavator is parked on a level surface, and the engine is off. Also, ensure that the hydraulic system is depressurized, and all attachments are lowered to the ground. Always wear appropriate personal protective equipment such as gloves, goggles, and safety boots.

Step 2: Locate the hydraulic oil tank

The hydraulic oil tank is where the hydraulic oil is stored. It is usually located on the right side of the excavator's rear end, near the cabin. The hydraulic tank has a dipstick or sight glass that you can use to check the oil level.

Step 3: Check the oil level

To check the hydraulic oil level, you need to remove the dipstick or look at the sight glass. If your excavator has a dipstick, unscrew the cap and pull out the dipstick. Wipe it clean with a rag and insert it back into the tank. Do not screw the cap back in. Pull out the stick again and check the oil level. The oil level should be between the two marks on the dipstick.If your excavator has a sight glass, you don't need to remove anything. Look at the sight glass, and you should see the oil level between the upper and lower marks. If the oil level is below the lower mark, it means you need to add more oil.

Step 4: Add more oil if necessary

If the hydraulic oil level is low, you need to add more oil. Make sure you use the right oil recommended by the manufacturer. Using the wrong oil can damage the hydraulic system. Open the hydraulic oil tank cap and pour the oil slowly into the tank. Check the oil level frequently to avoid overfilling the tank. Once you reach the correct oil level, screw the cap back in or put back the dipstick.

Conclusion

Checking the hydraulic oil level is a simple but crucial task that you need to perform regularly to keep your Hitachi excavator running smoothly. Remember to take safety precautions before checking the oil level, locate the hydraulic oil tank, check the oil level, and add more oil if necessary. Regular maintenance of the hydraulic system will prolong the life of your excavator and save you from costly repairs.
