how do you get the lockout lever to work on a 290 komatsu excavator
The lockout lever on a 290 Komatsu has a safety device that prevents rocks and other objects from going through the air intake. When you go to engage the brake, the lockout lever should move over to where you can reach it easily with your finger. The lockout actually has teeth on it, so you can get your fingers around it and move it to a closed position.

The Komatsu PC290LC-10 Hydraulic Excavator is equipped with a Tier 4-certified Komatsu SAA6D107E-3 engine. This engine uses cooled Exhaust Gas Recirculation (EGR), a Diesel Particulate Filter (DPF) and a Selective Catalytic Reduction (SCR) system to meet EPA Tier 4 Final emission standards.
The catwalk is designed for comfort, safety and convenience. It has a fully adjustable seat. The armrests are height adjustable, and the left armrest is equipped with the lockout lever. The track adjuster can be adjusted in one step from the catwalk.
Lever lockouts allow for an easy override of multiple lockouts in a single area by providing an additional level of protection by requiring personnel to visibly remove the lockout from each device before activating energy source.
290 komatsu excavator-does anybody know why the lockout lever is not working on a 290 komatsu excavator the hydrulic fluid level is good and there are no leaks
The boom and stick lockouts on my Komatsu are hydraulic, not mechanical. If the lever isn’t working, it’s because there is either no hydraulic pressure in that circuit or there is a leak in it. You should be able to trace the hoses back from the lockout cylinder to see where they go. There should also be a block diagram somewhere in the machine (probably in the cab) that shows where the lockout circuit ties into the rest of the machine’s hydraulics. I would check for flow at those points first.
I had a similar problem when I was rebuilding my PC200. One of the lockout valves started leaking, so I installed a new one, but that didn’t solve the problem. As it turns out, it was leaking internally and would only hold pressure with all three valves closed. I solved this by using a T-fitting to tie into one of the other lockout valves and manually open both of them at once to operate the machine with only two lockouts.
If you keep running into problems with lockout valves leaking on Komatsu excavators, you might want to consider installing aftermarket manual block valves on each cylinder instead of relying on hydraulic lockouts.
290 komatsu excavator-One of the main reasons for the locking lever not moving up or down on a Komatsu excavator is that it is frozen.
One of the main reasons for the locking lever not moving up or down on a Komatsu excavator is that it is frozen. There are two things you need to do to fix this,
First, and most important, is to check all of your cylinder pins for excessive wear. If these pins have too much wear in them, the linkage will become frozen.
Second is to heat the pin up with a propane torch or a heat gun until it has a blue glow on it. This will expand the pin and release any rust that might be holding the linkage together. This can be done easily in under an hour.
290 komatsu excavator-If the Komatsu excavator’s lever does not move, then the only possible reason for this is some kind of damage.
If the Komatsu excavator’s lever does not move, then the only possible reason for this is some kind of damage. Therefore, if you have encountered a similar malfunction, then the first thing to do is to establish the cause of this breakdown. What are its main causes?
First of all, it is necessary to check the presence of incoming power supply to the solenoid valve operating mechanism. In case there is no power supply, then it is necessary to establish what led to a similar failure: perhaps a faulty generator or voltage regulator.
Next, you should check whether there is an incoming power supply to the solenoid valve operating mechanism. If there is no power supply, then it is necessary to establish what led to a similar failure: perhaps a faulty generator or voltage regulator.
In addition, it is necessary to pay attention to the condition of the cables that transmit current from these devices and make sure that they are not damaged.

290 komatsu excavator-Locking lever problems on a Komatsu 290 excavator are a common issue.
Locking lever problems on a Komatsu 290 excavator are a common issue. It’s an easy fix as well. You’ll need to open the filter housing by removing the plastic cover, which will give you access to the locking lever itself.
You can use heavy duty or regular plyers to release the plastic nipple from its housing and then reconnect it with a solid click. Make sure you connect it tightly so it doesn’t slip off again.
