To Next PageTo Next PageWhat to do if my Hitachi Koki CG 25EUS Trimmer starts, but when it accelerates…?
If your Hitachi Koki Trimmer starts but stalls when accelerating, the fuel filter may be clogged and needs cleaning or replacement. Also, inspect for extended valve clearance, loose nuts, or a worn push rod, and repair or replace the parts as necessary. A muffler clogged with carbon can also cause this issue, so clean the muffler.
Why does my Hitachi Koki CG 25EUS stop idling after starting?
If your Hitachi Koki Trimmer starts but then stops idling, the spark plug may be stained or faulty, requiring cleaning or replacement. Check the air gap between the magneto rotor and ignition coil and adjust if necessary. A worn piston ring will need to be replaced. Also, carbon accumulation on a sealed valve surface or a carburetor clogged with foreign matter can cause idling to stop; clean these parts. Finally, the idling speed might be too low and require adjustment.
How to fix a Hitachi Koki CG 25EUS when the starter handle cannot be pulled?
If the starter handle of your Hitachi Koki Trimmer cannot be pulled, it might be due to a stuck piston ring or connecting rod bearing, in which case you should disassemble the engine and replace the faulty part. Alternatively, a damaged valve, crank gear, or cam gear could be the cause, and replacing the faulty part will solve the issue.
