Considering that there are so many different kinds of excavators out there, it makes sense for you to want to know about how to turn up thumb hydraulic pressure komatsu excavator. This is just one of the many pieces of information that you will be able to find when you read the following article. You may not know all that much about excavators, but by the time you finish reading this article, you could very well be an expert on how all excavator work.

thumb hydraulic pressure komatsu excavator-Locate the thumb valve on the excavator’s control panel.

Locate the thumb valve on the excavator’s control panel. The controls are typically located on the right armrest of the excavator, and the thumb valve looks like a small wheel that you must engage with your left thumb. This thumb dial allows you to raise and lower the bucket attached to the end of your excavator’s mechanical arm.

Before you operate your Komatsu excavator, you must open the cooling system drain valve. Locate this valve on the bottom of your excavator’s radiator. The radiator is located behind a protective wire grill directly in front of your operator cab. There is a long handle with a wheel at its end near the radiator. Move this wheel counter-clockwise until you hear hissing noises coming from under your excavator’s hood.

thumb hydraulic pressure komatsu excavator-Read the thumb valve’s pressure gauge and note its current reading.

Read the thumb valve’s pressure gauge and note its current reading. The thumb valve is located on the side of the air tank, just below the compressor’s motor. There is a small gauge attached to this valve, which will give you an instant readout of your tank’s pressure level.

Read the compression guage and note its current reading. This is a-bit less obvious, since it requires that you remove the spark plug from your lawnmower and insert the compression tester into the spark plug hole. On most compression testers, there is a gauge on one end that will give you an instant readout of your mower’s cylinder pressure level.

thumb hydraulic pressure komatsu excavator-Remove the engine cover on the excavator to locate the thumb valve.

Remove the engine cover on the excavator to locate the thumb valve. The thumb valve is a small lever that serves as a hydraulic bypass for the thumb. When the thumb is not in use, the valve must be moved to the “neutral” position.

Move the valve to the “neutral” position by pushing the release lever on top of it and moving it forward to align with the arrow on top of the release lever.

Loosen and remove the two bolts holding each end of the control cable using an open-end wrench.

Remove the control cable from each end of its routing slot by pulling it out of its clips on each side of the machine.

Attach one end of a new control cable to one end of its routing slot and secure it in place by tightening its retaining bolt with an open-end wrench.

Pull both ends of the new control cable through their routing slots until they reach their anchor points at each end. Repeat this process for both ends of your excavator’s control cables.

thumb hydraulic pressure komatsu excavator-Turn the thumb valve until you see its pressure gauge increase.

Turn on the pressure washer by turning the switch to the “On” position.

Turn the thumb valve until you see its pressure gauge increase. If your pressure washer has a hose reel, extend the reel fully by turning it clockwise.

Connect one end of the hose to the wand and the other end to the pump inlet on the pressure washer.

Spray water onto a surface that won’t be damaged by high-pressure water spray, such as a driveway.

Slowly pull the trigger on the wand until water sprays from it. Slowly release it when you’re done spraying.

thumb hydraulic pressure komatsu excavator-Test the increased pressure by using the excavator’s thumbs to lift an object, then repeat Step 5 if necessary.

If you need to increase the pressure of your excavator’s thumbs, it is possible without having to completely disassemble the machine.

Steps

1.Turn off the engine and wait for the excavator to stop moving. Allow the bucket to reach a resting position on the ground, then set the parking brake.

2.Open the cab door and climb out of the excavator.

3.Walk around to the back of the excavator and locate either side of the hydraulic lines that extend from the cylinder on each thumb to connect with fittings on each end of the main hydraulic line. Identify which line is connected to which fitting on each thumb.

4.Unfasten one end of each hydraulic line from its respective thumb fitting, then remove both ends from their respective cylinders by twisting them counterclockwise on their threads until they’re free from their fittings. Remove them from their respective cylinder fittings and set them aside.

5.Locate a second pair of hydraulic lines that lead to a valve in front of where you removed your original lines from their cylinders. These additional lines are often yellow or green in color with black stripes around them; however, an individual manufacturer may not follow this color scheme when engineering these lines for this particular.

thumb hydraulic pressure komatsu excavator-Increase your hydraulic pressure to improve your excavator’s effectiveness.

Excavators are one of the most versatile pieces of construction equipment available. They can be used for almost any construction job, from installing sewer lines to removing tree stumps. Hydraulic pressure is the lifeblood that powers an excavator. The better your hydraulic pressure, the more effective your excavator will be.

Here’s how to increase your hydraulic pressure:

Step 1: Check for leaks in all hoses and connections. A small leak can reduce your hydraulic pressure significantly. Repair all leaks before proceeding.

Step 2: Adjust the relief valve on the pump to increase hydraulic pressure. Refer to your owner’s manual for instructions on how to do this.

Step 3: Test the hydraulic system after adjusting the relief valve. If you still need more power, continue to step 4.

Step 4: Locate the oil filter and replace it with a new one if it looks dirty or clogged. This should improve your machine’s performance if the filter is dirty or clogged.

Step 5: Replace all worn out hoses with new ones if necessary and check all hoses again for leaks after replacing them.

thumb hydraulic pressure komatsu excavator-Ensure that the oil level of the hydraulic system is normal and that there is no leakage in the hydraulic system.

Ensure that the oil level of the hydraulic system is normal and that there is no leakage in the hydraulic system.

1. Check if there is oil leakage in the hydraulic system.

2. Check if the hydraulic system oil shows that it is normal, too high or too low.

3. If necessary, replace the lubricating oil in time to ensure that the oil level is normal and keep it clean.

thumb hydraulic pressure komatsu excavator-Perform a detailed inspection of the thumb component, tighten all loose parts and check for damage or wear and tear.

1. Perform a detailed inspection of the thumb component, tighten all loose parts and check for damage or wear and tear.

2. Inspect all fluid levels, change oil and filters, inspect cooling lines and connections for leaks, inspect hoses for leaks or damage.

3. Inspect engine compartment for leaks or damage to wire harnesses and hoses.

4. Inspect fuel system for leaks or damage to lines, fittings, tank or cap.

5. Check seat belt warning light operation and seat belt condition.

6. Check exhaust system for leaks and clearance to underbody components; inspect muffler/silencer for deterioration or damage; inspect bracket-mounting bolts for tightness; if equipped with vertical exhaust stack, inspect stack mounting bolts for tightness.

7. Inspect machine lights (headlights, tail lights, worklights, strobe).
