Hyster H80XM LPG

  • Posted 22 Nov 2019 11:06 AM
Hi, I am having a issue with the forklift stumbling. Starts and runs fine but at idle it will stumble like it's about to die for about 1 second, then run fine again. This happens about every 5 to 10 seconds. If I give the unit throttle it will rev up, but it still stumbles, about every 5 to 10 seconds at higher RPM's.

Thanks in advance for the help.

some of these units have what they call a dashpot on the throttle.
if it is not adjusted correctly it can allow the throttle to drop too low or have a surge in it like what you are describing.
On the higher rpm's i'm not sure what that might be unless it has a mechanical governor on it, if thats been tampered with it might be out of adjustment causing that surge.

You've been swooped!
