Why won't my Hitachi Zaxis 38U-5A Excavators engine start?
Your Hitachi Excavators engine might not start due to several reasons: a discharged battery (charge or replace it), disconnected, loose, or corroded battery terminals (repair the corroded area and tighten the connectors), a lowered pilot control shut-off lever (pull it up), disconnected, loose, or corroded starter ground line terminals (repair the corroded area and tighten the connectors), a faulty pilot control shut-off lever electrical system (repair it), too high engine oil viscosity (change the engine oil with appropriate viscosity), or a faulty starter and/or electrical system (repair and adjust).
What to do if my Hitachi Zaxis 38U-5A coolant temperature is too high?
If the coolant temperature in your Hitachi Excavators is too high, it could be due to: low coolant level (refill it), insufficient fan belt tension (adjust it), a damaged rubber hose (replace it), a faulty thermostat (replace it), or a faulty coolant temperature gauge (replace it).
What to do if my Hitachi Excavators starter rotates but the engine doesn't start?
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?
An irregularly running engine in your Hitachi Excavators may be caused by a faulty fuel system (repair and adjust), water or air in the fuel system (drain water or bleed air), or a faulty engine control system (repair and adjust).
Why do Hitachi Zaxis 38U-5A have no hydraulic functions and noise from pumps?
If your Hitachi Excavators has no hydraulic functions and there's noise from the pumps, it could be due to a faulty hydraulic pump (repair or replace), a lack of hydraulic oil (refill), or a broken suction pipe and/or hose (repair or replace).
Why is my Hitachi Zaxis 38U-5A Excavators lever heavy to operate?
If the lever on your Hitachi Excavators is heavy to operate, it might be due to a rusted joint (lubricate or repair) or a worn pusher (replace).
What causes Hitachi Zaxis 38U-5A Excavators not to move smoothly?
If your Hitachi Excavators does not move smoothly, it could be caused by a worn pusher (repair or replace) or a faulty pilot valve (replace).
