What to do if my Kubota KJ-S150VX circuit breaker turned OFF?
If the circuit breaker on your Kubota Portable Generator turns off, it could be due to a short-circuited cable or overload. Reduce the load. For a short-circuited cable, contact a qualified electrical engineer for inspection.
What to do if my Kubota KJ-S150VX Portable Generator pilot lamp failure to light up?
If the pilot lamp on your Kubota Portable Generator fails to light up, it could be due to a broken lamp bulb (replace the bulb) or the generator voltage being too low (see "Voltage failure to rise" above).
What to do if the fuel of my Kubota KJ-S150VX is thick and doesn't flow?
If the fuel in your Kubota Portable Generator is thick and doesn't flow, check the fuel tank and fuel filter. Remove water, dirt, and other impurities. As all fuel will be filtered by the filter, if there should be water or other foreign matters on the filter, clean the filter with kerosene or replace the filter.
What to do if my Kubota KJ-S150VX Portable Generator's fuel injection timing is wrong?
If the fuel injection timing is wrong on your Kubota Portable Generator, adjust the injection timing. For engine model D1703-EBGx, the injection timing is 15.5º before top dead center. For engine model V2203-EBGx, the injection timing is 17.0º before top dead center. For engine model V3300-EBGx, the injection timing is 10.0º before top dead center.
What to do if my Kubota KJ-S150VX is voltage hunting?
Voltage hunting in your Kubota Portable Generator can be caused by an inverter or similar switching load connected (disconnect such load) or a faulty AVR (replace the AVR).
What to do if the voltage of my Kubota KJ-S150VX Portable Generator fails to rise?
If the voltage fails to rise in your Kubota Portable Generator, it could be due to several reasons: maladjusted voltage (readjust using the voltage control), a broken AVR excitation output cable (repair the cable), a faulty AVR (replace the AVR), a short-circuited or broken exciter winding (replace the generator), a broken AVR excitation input cable (repair the cable), a broken generator winding (replace the generator), or a blown AVR excitation output fuse (replace the fuse).
What to do if my Kubota Portable Generator has low compression?
Insufficient compression in your Kubota Portable Generator can be caused by a bad valve or excessive wear of rings, pistons, and liners. Replace with new parts.
What to do if the voltage of my Kubota KJ-S150VX is too high?
If the voltage of your Kubota Portable Generator is too high, it could be due to maladjusted voltage (readjust using the voltage control), a broken AVR voltage detection cable (repair the cable), a faulty AVR (replace the AVR), or a conductive load connected such as a mercury arc lamp (disconnect such load).
Why is my Kubota KJ-S150VX making unusual noise or vibration?
Unusual noise or vibration in your Kubota Portable Generator can be caused by a single-phase load applied beyond the allowable level (lower the load to acceptable level), a deteriorated bearing (replace the bearing), or a damaged coupling (replace the coupling).
Why is my Kubota KJ-S150VX Portable Generator frame overheated?
The frame of your Kubota Portable Generator might be overheating due to several reasons: the cooling fan inlet or outlet is blocked (unblock the inlet or outlet), the voltage is too high (readjust the voltage), or the generator is overloaded (reduce the load).
