What does '*ERR error code' mean on Kubota U35-4 Excavators and how to fix it?
The '*ERR error code' indicates a problem that could be caused by a poor sensor connection. Remove and refit the pod connection cable to resolve this. Alternatively, it may indicate corrupted coding. Access the factory setup and perform a default reset using pin 6759.
Why is the pressurizer on my Kubota U35-4 Excavators running at full speed and noisy?
The pressurizer might be running at full speed and noisy due to several reasons: * The filter may be blocked, requiring service. * A door or window might be open; ensure they are securely shut. * The cabin sealing capacity might be inadequate; perform a pressure test and seal any leak points. * The sense pipe could be blocked; ensure it is clear and not bent. * The internal sensor could be damaged, requiring controller replacement.
What to do if my Kubota Excavators displays a low pressure alarm?
If the Kubota Excavators displays a low pressure alarm, it could be due to several reasons: * A door or window is open. Ensure all doors and windows are securely shut. * The cabin sealing capacity is not adequate. Perform a pressure test procedure and rectify the cab sealing. * The pressurizer is not operating. Ensure the correct voltage (12v or 24v) is supplied to the pressurizer motor pin A. * The pressure sense tube is blocked. Unplug it at the monitor and ensure clear flow to the exterior of the cabin. * There is a poor power supply. Check the 20A mains fuse and ensure the correct voltage. * There is a poor earth connection. Check the earth continuity at motor pin B.
What to do if filter blocking quickly in Kubota U35-4 Excavators?
If the filter is blocking quickly, it may be due to defective cabin sealing. Perform a pressure test procedure and seal any leak points as required. Alternatively, the pre-cleaner may have failed; check its operation and replace it if necessary.
What to do if my Kubota Excavators controller showing 0.0 pressure?
If the controller is showing 0.0 pressure, the fresh air filter may be blocked. Check the filter condition and replace it if required.
What to do if my Kubota Excavators display is blank?
If the display is blank, check the mains supply fuse and correct voltage, as there may be a poor power supply. Alternatively, the controller may have failed, requiring monitor replacement.
What does '*Check filter alarm' mean on Kubota U35-4 Excavators and how to fix it?
The '*Check filter alarm' is triggered by a service hour timeout. To resolve this, access the Check Runtime menu and reset the hours using code 7597.
What to do if there is a Temperature / CO2 error on Kubota U35-4 Excavators?
If there is a Temperature / CO2 error, it could be because the sensor is not connected. Fit the sensor or disable it via the site access CO2 and/or temperature menu.
Why is my Kubota U35-4 Excavators having starting difficulties?
Your Kubota Excavators may be having starting difficulties due to several reasons. The pilot control lock lever might be in the "UNLOCK" position, in which case you should bring it to the "LOCKED" position. Alternatively, the fuel could be too viscous, requiring you to check the fuel tank and filter for impurities and water, and replace the filter if necessary. Another possibility is air or water in the fuel system; remove any water from the fuel tank and check the fuel pipe joint bolts and nuts for looseness. If the oil viscosity is too high, especially in winter, pour hot water over the radiator. Finally, a nearly dead battery or insufficient compression could be the cause, requiring you to recharge the battery.
What to do if Kubota U35-4 water temperature is in red zone (Overheating)?
If your Kubota Excavators is overheating, several issues could be the cause. It could be due to a defective water pump seal, which needs replacement. A worn or torn V-belt should be adjusted or replaced. A defective thermostat also requires replacement. Low coolant level needs to be addressed by filling to the prescribed level. Clogged radiator grill or fins should be cleaned. Coolant contaminated with rust requires replacement and the addition of anti-rust. A defective radiator cap should be replaced. Corroded coolant pipes should be cleaned. Finally, continuous operation under full load requires a reduction in load.
