If the starter rotates but the engine doesn't start in your Hitachi Excavators, check for: no fuel (refill it, ensuring there are no leaks), a faulty injection pump (repair and adjust), air in the fuel system (bleed the air), a clogged fuel filter (drain water and replace the element), frozen fuel (warm the fuel pump with hot water or wait for the temperature to rise), or a faulty preheat system (repair and adjust).
Why do Hitachi Zaxis 38U-5A batteries discharge quickly after being charged?
If your Hitachi Excavators batteries discharge quickly after being charged, the cause might be a shorted cable (repair or replace), a shorted battery separator (repair or replace), or increased sediment in the battery (replace the battery).
What to do if Hitachi Zaxis 38U-5A engine stalls soon after starting?
If your Hitachi Excavators engine stalls soon after starting, it could be due to: too low idle speed (repair and adjust), a clogged fuel filter (drain water and replace the element), a clogged pre-fuel filter (clean or replace the element), a faulty engine control system (repair and adjust), a clogged air cleaner (clean or replace the element), or a faulty injection pump (repair and adjust).
Why is my Hitachi Excavators engine running irregularly?
