Cat Lift Trucks (& Caterpillar) EX500:
H1 and H2 codes

We are having a similar issue with an EP25K s/n ET89C50700.

H1, H2 and H3 errors are appearing. We can hear the hydraulic pumps working but no mast functions will operate. Is it related to voltage at the valves? If there is no voltage at the valve where do we look from there?

Thanks
Colm

i'm sure you have figured this out by now
the H1 and H2 codes have to do with the hydraulic lever switches being closed before they are supposed to be, 'out of adjustment' to be more precise.

for future reference though posting the correct model number and also giving a truck serial number will get you a better return on your inquisitions in the future ;o)
