When the komatsu mini excavator won’t start, running a self-diagnosis test can be very helpful in isolating the problem. However, this simple test is done differently than you would expect on some models. This article takes a look at how to do it right.

check komatsu mini excavator fuel

This is an important safety procedure that should be done before starting the engine on your komatsu excavator.

Step 1

Open the fuel cap on the komatsu excavator, located on the right side of the engine block. This will keep pressure from building up in the gas tank as it heats up and pushing fuel out of the tank when you remove the fill cap.

Step 2

Run your hand over the top of the fill cap to ensure there is no debris or trash caught under it. If the cap is loose, this could potentially block fuel from entering the tank and cause problems with a lack of fuel to feed into the motor.

Step 3

Turn off any power to your komatsu excavator, including any lights or heaters attached to it. This will prevent accidental electrocution if you drop something into a puddle of spilled fuel.

Step 4

Unscrew the fill cap on top of your komatsu excavator’s gas tank and check for fuel inside. If there is enough fuel in there to start up, screw the fill cap back in place until it is tight and then start up your excavator normally.

komatsu mini excavator hydraulic fluid is full

If you have a komatsu mini excavator, then there is a good chance that it has what is known as Kubota hydraulic fluid. This type of fluid is different from the typical oil that you would use for your car or truck. The reason for this is because it needs to be able to withstand higher temperatures and pressures than most types of fluids.

If you are wondering what the difference between the two types of fluids are, then this article is going to give you some information on komatsu hydraulic fluid.

First of all, it needs to be able to handle extreme temperatures. In order for the hydraulic system to work properly, it needs to be able to maintain its viscosity at all times. If you were using regular motor oil in your hydraulic system, then it would start to break down and become less effective after just a few minutes of running time. That’s not what you want when you’re trying to get your equipment working properly!

Another important thing about komatsu hydraulic fluid is that it’s designed specifically for use with their systems. You should never try and use other types of fluids such as diesel or gasoline in your Kubota mini excavator because they could damage the system or cause leaks which could result in costly repairs down the road.

check komatsu mini excavator engine oil

Checking the engine oil level in a komatsu mini excavator is important to ensure that the engine has the proper level of oil and to make sure that no contaminants have gotten into the oil pan. Cleaning the dipstick each time you check the oil will help make certain that you get an accurate reading of the oil level.

1. Turn the excavator on and allow it to warm up for five minutes.

2. Turn the excavator off and wait for 10 seconds.

3. Locate the oil dipstick on the excavator’s engine. It is located just below the cab with a red plastic handle on it.

4. Remove the dipstick and wipe it clean with a rag or paper towel.

5. Insert the dipstick into its hole and pull it out again to check the level of the engine oil. If it is not between the two marks, you need to add more engine oil to your excavator’s engine.

check komatsu mini excavator glow plugs

If the vehicle is equipped with a komatsu mini excavator glow plug, the terminal should be checked for an open circuit or a short to ground. If there is no voltage at the glow plug control module terminal, the operator must check the control module’s power and ground circuits. The control module is energized when cranking or running, so it may be necessary to crank the engine in order to test for voltage on the power side of the circuit.

The glow plugs are located in a chamber that is connected to a reservoir of diesel fuel. When a vehicle’s engine is cold, it will use less fuel than a warm engine due to lower combustion temperatures. This results in an increase in exhaust temperature from unburned fuel particles (unburnt hydrocarbons), which increases pollution levels. komatsu mini excavator glow plugs help warm up engines quickly by preheating the combustion chamber before starting.

1. Glow Plug Switch (if equipped) – Pushes in to activate or deactivate the glow plug system.

2. Glow Plugs – Heat the combustion chamber, providing a warm environment for easier starting.

3. Glow Plug Indicator Light (if equipped) – Illuminates when the key switch is turned to the ON position and goes off when the engine starts.

check komatsu mini excavator glow plug fuse wiring and relays

Starting with the glow plugs. You should have a voltage of 12V at the glow plug. This is how you check it and what you should be seeing. If you only see one spark then there is no problem with the plug or wiring but with the ECM or other parts involved in the starting sequence.

1, remove the power from the glow plugs by removing the relay and disconnecting the battery.

2, connect a volt meter between ground and one of the glow plugs. I used an old school analog volt meter for this but any digital multi-meter will do just fine.

3, turn on your key so that your glow plug relay is energized, but don’t start your engine yet.

4, you are now measuring actual DC voltage coming from your battery to your glow plug except that it’s being interrupted by firing of each plug sequentially as it’s designed to do. You should see 12 volts at first then quickly dropping down to 6 volts and back up again several times as each plug fires and returns to rest until they all fire and return to rest simultaneously at which point you will see a steady 12 volts at your test probe (negative lead of meter) and ground (positive lead of meter).

check for any komatsu mini excavator blown fuses

If your car’s dashboard has a check engine light on, do you check the fuses? Chances are you don’t. So when your komatsu mini excavator starts acting up, it’s easy to simply assume the worst and take it in to the shop. But there are some things you can do before calling a mechanic. For example, you can check the mini excavator’s fuses yourself. Here are some steps for how to do that:

The first thing you need to do is locate the fuse box. If your mini excavator is fairly new, it will be located under the left side of the instrument panel at the operator’s station. Older models will have this box under a hood next to the driver’s seat.

Open either of these boxes, and look through all of its fuses. You may need a flashlight or a screwdriver to help you out with this step. If any of them look burned, especially those that cover essential functions like headlights or fuel pumps, then they must be replaced immediately.

check to komatsu mini excavator make sure the exhaust isn’t clogged

One of the most important things to check when you have a komatsu mini excavator that won’t start is the air filter. If the air filter is clogged, it will restrict the amount of air getting into the engine, making it impossible for it to start.

Another thing to check is that there is fuel in the tank. With a komatsu mini excavator, you’ll also want to make sure that the fuel pump isn’t faulty. It could be that you’re not getting enough fuel to your machine, which means it has trouble starting as well.

The other thing to check on your Kubota mini excavator is that there are no leaks. If there are any leaks in the fuel line or elsewhere in your machine, it can cause problems with starting as well.

Check the komatsu mini excavator battery fluid levels, making sure that the fluid levels are topped off

When you suspect that there is a problem with the construction equipment, then you should take immediate steps to solve it. Otherwise, you may suffer from a severe loss. Sometimes, the maintenance department overlooks some problems that can worsen in future if not rectified on time.

For example, when the hydraulic system of a machine is not working properly or if the hydraulic fluid is leaking, then it should be fixed immediately. If not, your equipment will stop working and your business will suffer.

So, how can you detect such problems? In this blog post, we will discuss some common problems that can occur in construction equipment and how to prevent them by inspecting your machines regularly.

1. Check the komatsu mini excavator battery fluid levels, making sure that the fluid levels are topped off.

2. Inspect all rubber hoses for cracks and leaks as well as signs of wear around the outside edges where they connect with metal fittings at both ends of each hose section; replace any worn hoses before they break down completely (which could cause serious damage).

3. Check for oil leaks at all points on an engine
