According to our Tech Support Department, these questions are routinely answered:

Q. What kind of hydraulic oil should I use in my Barreto equipment?
  • We use AW/ISO 68 hydraulic fluid in all Barreto equipment. If you are operating your machine below 32°F, then AW/ISO 46 is recommended.
Q. Does your equipment ship with hydraulic oil, or do I have to fill the tank when I receive the machine?
  • The equipment ships with a full tank of hydraulic oil. Just fill the gas tank, check your engine oil level to make sure it is properly filled, and you’re ready to start.
Q. How much fluid should be in the hydraulic tank?
  • The hydraulic fluid level should be visible about half way up in the sight glass on the side of the machine. For those older machines that do not have a sight glass, fill the tank to within 3 inches from the top of the tank.
Q. I need to add hydraulic fluid to my machine but do not have a tool to remove the fill plug. What kind of tool do I need?
  • The fill plug takes a 9/16” hex tool to remove.
Q. How often should I change my hydraulic filter?
  • For new machines, replace the filter after the first 50 hours. Then, every 200 hours thereafter. Also, add one quart of hydraulic fluid to the tank with every filter change.
Q. My hour meter is flashing. How do I reset it?
  • Luckily, that’s simple - just wave a magnet above the hour display in the upper right-hand corner.
Q. What is the warranty on a Barreto?
  • We offer a 1 year Manufacturer’s Warranty that guarantees your product to be free of defects in materials and workmanship. Engines, engine accessories, batteries, and tires are warranted by the original manufacturers and are not covered by the Barreto Equipment Warranty. Honda and Briggs engine options come equipped with a 3-year Engine Manufacturer’s Warranty.
