Bryan Thomson of Sapphire Scientific walks through basic 370 truckmount maintenance checkpoints, including oil levels, air filter, waste tank filters and strainer baskets, blower filters and vacuum blower lubrication.
By following the recommended service schedules as outlined in the owner's manual you can expect thousands of hours of operation. It is not uncommon to see 370s with over 5000 hours on them and no major components requiring replacement.
Its junk. Only 1000 hours and many problems. I only use it about 350 hours a year. 3 years old with 1000 hours. I can only clean about 1000sqft before having to dump because of a bad valve. Now I have to spend $200 because it needs a RE DESIGNED valve in order to make it work like it did upon purchase. I called Scott Harlib to talk about it and he never returned my phone call. Very dissatisfied customer. I've been in business 28 years, the last 20 using the same Hydromaster. I should have stuck with them.
