Hi all,I'm running a Terex RT 230 that has a heat pump style cab heater. You have to keep the RPMS over 1500 to get anything close to luke warm air out of it and it's not even cold yet. Was hoping someone could point me in a direction of were to get a manual or idea of what to look at
Check the heater hoses end to end, they can flatten out when run through and over bad areas.
