What to do if Kubota KX91-3a2 engine does not start but starter turns?
If your Kubota Excavator's engine doesn't start but the starter turns when you turn the starter switch to the START position, it could be due to air or water in the fuel system. You should check the fuel system for leaks and bleed it. Also, check the water separator for water content and drain it if necessary.
What to do if starter does not turn on Kubota KX91-3a2?
If the starter does not turn when the starter switch is turned to the START position on your Kubota Excavator, it could be due to a depleted battery or the control lever lock not being raised. You can charge the battery, jump-start the excavator or raise the control lever lock.
Why is the coolant temperature gauge in the 'H' zone on my Kubota KX91-3a2?
If the coolant temperature gauge is in the "H" zone on your Kubota Excavator, it could be due to several reasons: * A dirty radiator, in which case you should clean the radiator. * Low coolant level, so check the coolant level and add coolant if needed. * Leaks in the cooling system, so inspect the system for leaks. * A loose V-belt, so check and adjust the V-belt tension.
Why is there a deviation in the driving direction of my Kubota KX91-3a2 Excavators?
If you notice a deviation in the driving direction of your Kubota Excavator, it's likely due to the crawler tension being adjusted incorrectly. To resolve this, check and adjust the crawler tension as needed.
Why does the charge message display on my Kubota Excavators?
If the charge message displays on your Kubota Excavator, it may be due to a loose V-belt or a defective fuse in the alternator circuit. Check and adjust the V-belt tension and replace the fuses.
Why is there insufficient engine power in my Kubota KX91-3a2 Excavators?
If you experience insufficient engine power in your Kubota Excavator, it could be caused by a restricted air filter, a restricted fuel filter, or water in the fuel system. To address this, check and clean the air filter, check the water separator for water content and drain if necessary, and replace the fuel filter.
Why is the exhaust gas color very black in my Kubota Excavators?
If the exhaust gas color is very black in your Kubota Excavator, it's likely that the air filter is restricted. You should check and clean the air filter.
Why are there no pilot-controlled hydraulic functions available on my Kubota KX91-3a2 Excavators?
If you have no pilot-controlled hydraulic functions available on your Kubota Excavator, it's likely due to a defective fuse in the fuse box. Replace the fuses to resolve this issue.
What to do if indicator lights do not come on as expected on Kubota KX91-3a2 Excavators?
If the indicator lights do not come on as expected when the starter switch is turned to the RUN position on your Kubota Excavator, it is likely due to a defective fuse. Replace the fuses to solve this problem.
Why is the power of hydraulic functions too low on my Kubota Excavators?
If the power of hydraulic functions is too low or disruptive on your Kubota Excavator, it could be due to a low hydraulic oil level or a restricted suction filter. You should check the hydraulic oil level and top up if necessary, and change the hydraulic oil tank suction filter.
