A hydraulic excavator is used for digging or moving of soil or rock and helps in the formation of a particular landform. They are also used to move large rocks, piled debris and other materials. There is usually an oil supply tank attached to the rear part of the bucket which must be taken care of for the smooth functioning of the machine. Any defects in the hydraulic oil not only slow down the regular working but also affect most vital components. It is necessary to regularly check and maintain these parts as they help in moving dirt, debris and rocks up to 50 tons with ease.

Step 1. Open komatsu excavator hood or the engine compartment and locate the hydraulic fluid reservoir.

Remove the cap from the hydraulic fluid reservoir.Check the fluid level on the dipstick. The fluid should be at or near full level. If it is not, add hydraulic fluid until the level is at the full mark on the dipstick. Check the color of the hydraulic fluid in the reservoir. The fluid should be clear and amber in color. Dark or black hydraulic fluid may indicate contamination or excessive heat, both of which can require new hydraulic fluid to be added to the system. If this is the case, consult your Komatsu excavator service manual for further assistance with flushing and replacing contaminated hydraulic fluid or other repairs that may need to be performed to repair damage done by overheating or filter clogging. Place a clean rag over the opening of any container you pour used hydraulic fluid into to prevent spills when pouring oil into a recycling container as well as exposure to skin when pouring oil into a garbage can for disposal purposes.

Step 2. Use a flashlight to check komatsu excavator inside the reservoir when it is dark.

The hydraulic oil is a very important component of the hydraulic system. It serves as a lubricant for the various moving parts in the system. It also helps transfer power from the engine to the hydraulic pumps and from there to other components of the system, such as a Komatsu excavator.
Because of its importance, it’s crucial that you check your hydraulic oil regularly. This will help you know if you need to refill it or if it needs to be replaced.Turn off your machine. This will help prevent accidents and injuries when checking your hydraulic oil.Use a flashlight to check inside the reservoir when it is dark. You can do this by opening up the reservoir cap and looking inside with the flashlight. If you don’t have access to a flashlight, wait until daylight and check then, using a mirror if necessary so that you can see into the reservoir more easily. Use a dipstick, if available, to check the level of hydraulic fluid in komatsu excavator . Some excavators may not have dipsticks for checking fluid levels so you will need to use another method to determine how much fluid is in there. The dipstick should be located on top of the reservoir or close by it.

Step 3. Dip the end of a wooden stick into the reservoir to check the komatsu excavator oil level if it is too high for you to see. What you want to do is simply see if there is sufficient oil in this machine as low hydraulic fluid levels can damage your machine.

Komatsu hydraulic fluid levels should be checked on a regular basis, and more frequently when you are using your equipment frequently. The hydraulic oil reservoir is usually easy to get to, as it will have a dipstick with markings on it similar to the other fluids in your vehicle.
Find the Reservoir The first step is to locate the reservoir for the hydraulic fluid. This is located in the engine compartment of your Komatsu excavator and should be easy for you to spot. It should be near where all the hoses connected to the hydraulic arms are connected. Clean Reservoir Once you’ve located the reservoir, clean it with a lint-free cloth or rag before checking the level of oil inside. This helps provide an accurate reading, as any dirt or grime on the outside of the reservoir can throw off your reading. Dip Stick into Oil Dip the end of a wooden stick into the reservoir to check the komatsu excavator oil level if it is too high for you to see. What you want to do is simply see if there is sufficient oil in this machine as low hydraulic fluid levels can damage your machine. 

Step 4. Wipe off excess oil on the end of the stick before checking the komatsu excavator actual level of hydraulic fluid by placing it against one of these ruler markings along the front side of this glass tube.

Park the komatsu excavator on a level surface and depress the clutch pedal fully. Turn the engine off and allow it to cool for at least 15 minutes before proceeding with the hydraulic oil check.
Raise the hood and locate the glass tube that is on the front end of the hydraulic reservoir. Remove the dipstick/level stick from this tube by gripping its handle firmly and pulling straight up. Wipe any residue from this stick before checking your fluid level against its markings using one of these methods: Checking a Komatsu Excavator With a Single Stick,Wipe off excess oil on the end of the stick before checking the komatsu excavator actual level of hydraulic fluid by placing it against one of these ruler markings along the front side of this glass tube. Read your results according to where you find oil on this stick in relation to these marks, as indicated below: Oil Level Markings and Results “H” stands for “high”, while “L” stands for “low”. Oil levels between these two marks indicate that your hydraulic fluid is at an acceptable level, while oil found below that mark indicates that you need to top off this supply.

Regularly checking hydraulic fluid level is necessary for komatsu excavator in case of causing any damage to komatsu excavator

To check the hydraulic oil of your Komatsu excavator, you must first turn on the motor. The next step is to wait a few minutes and then check the dipstick. This will allow you to see whether or not you need to add more oil. The last step is to fill up the oil tank.
If you are an owner-operator of a Komatsu excavator, you know that it is important for you to perform regular maintenance inspections on your equipment. Regularly checking hydraulic fluid level is one such inspection that should be performed at least once a week. There are three main steps to this particular inspection: Turn on the motor, wait a few minutes and then check the dipstick. If there is any oil at all on it after turning it off, then there’s probably too much in there already and no need to add more (unless there’s been some kind of leak). The last step is filling up the tank with new hydraulic fluid; however, if there was none left when you checked earlier today or yesterday morning then simply skip this step and go directly back inside your house where it will be cold enough outside again so as not to have any worries about overheating while driving down those long stretches of road.

Summary:

Furthermore, most of the large and small excavators use hydraulics to power various functions of the machine. Backhoe loaders use telescopic extensions and digging buckets using the hydraulic system. Very often, excavators require frequent movement and relocation in order to perform different tasks. On top of that, a damaged or clogged hydraulics system can bring your large machine to a grinding halt.
