What to do if my Kubota KX040-4 Compact Excavator has starting difficulties?

If your Kubota Compact Excavator is having trouble starting, consider the following: * Ensure the lock lever is in the "LOCK" position. * Check the fuel tank and filter for viscous fuel, removing any impurities or water, and replace the filter if necessary. * Remove water from the fuel tank if there's air or water in the fuel system. Check fuel pipe joint bolts and nuts for looseness. Purge the fuel system. * If the engine runs sluggishly in winter due to high oil viscosity, pour hot water over the radiator. * Recharge the battery if it's almost dead or there's insufficient compression.
