What to do if my Kubota KJ-S150VX Portable Generator has thick carbon deposits on orifice of injection nozzle?
If there are thick carbon deposits on the orifice of the injection nozzle of your Kubota Portable Generator, this is caused when water or dirt is mixed in the fuel. Clean the nozzle injection piece, being careful not to damage the orifice. Check to see if nozzle is working properly or not. If not, install a new nozzle.
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).
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).
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).
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 type of fuel should I use for my Kubota KJ-S150VX if the fuel is of extremely poor quality?
If the fuel in your Kubota Portable Generator is of extremely poor quality, select good quality fuel. Use No.2-D diesel fuel only.
What to do if my Kubota KJ-S150VX has a bad nozzle?
If your Kubota Portable Generator has a bad nozzle, replace it with a new one if necessary.
What to do if moving parts are overheated due to shortage of lubrication oil or improper lubrication in my Kubota Portable Generator?
If moving parts are overheated due to a shortage of lubrication oil or improper lubrication in your Kubota Portable Generator, check the amount of engine oil with the oil level gauge. Also, check the lubricating oil system. At every second oil change, the oil filter cartridge should be replaced. Check to see if the engine bearing clearances are within factory specs.
What to do if my Kubota KJ-S150VX has air or water mixed in fuel system?
If air or water is mixed in the fuel system of your Kubota Portable Generator, and air is in the fuel filter or injection lines, the fuel pump will not work properly. To attain proper fuel injection pressure, check carefully for loosened fuel line coupling, cap nut and etc. Loosen joint bolt atop fuel filter and air vent screws of fuel injection pump to eliminate all the air in the fuel system.
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).
