To address oil leaks in your Barreto Excavator's hydraulic system: * Ensure all fittings on hoses and piping are tightened. * Check the hoses for any breaks or abrasions, and replace them if needed. * Inspect the motor for leaks around the shaft seal; if a leak is present, consider ordering a seal kit or replacing the motor.
What to do if the engine of my Barreto Excavators lugs down and the wheels and chain stop turning?
If your Barreto Excavator's engine lugs down or dies, and the wheels and chain stop turning, here are some steps to take: 1. Try reversing the chain briefly to dislodge any obstructions. Lift the boom and stop the chain, then clear any obstructions from the trench. 2. Reduce ground speed or trenching depth. 3. Lubricate the chain or replace it if necessary. 4. Consult the engine manual for troubleshooting steps. 5. If trenching on hills, level the trencher, check the oil level, and allow the oil alert to reset. Refer to the engine manual for more details.
Why is foaming hydraulic oil coming from the breather hose on my Barreto Excavators?
If you observe foaming hydraulic oil coming from the breather hose of your Barreto Excavator, take the following steps: * Confirm that the hydraulic oil being used contains anti-wear and anti-foaming additives. * Check and tighten all fittings on the intake side of the pump. * To assess pump pressure, detach the top hose from the chain control valve and attach a 4000 psi pressure gauge. Start the engine and manually engage the chain valve lever to the “FORWARD” position. The output pressure should be around 3000 psi.
What to do if the entire hydraulic system of Barreto Excavators does not operate?
If the entire hydraulic system of your Barreto Excavator fails to operate and the engine isn't under load, you should: * Check the wheel drive valve cable adjustment and adjust or replace the cable. * Add oil until it is visible in the sight gauge. * Prime the pump. * Inspect the coupler for wear and replace both coupler halves and the rubber spider if needed.
What causes the wheels to fail to turn while the chain rotates on Barreto Excavators?
If the wheels on your Barreto Excavator fail to turn while the chain is rotating, consider the following: * Install pins and secure them with lock nuts. * Check the wheel drive valve adjustment and adjust the cable accordingly. * Inspect and tighten the fittings on the pump intake. * Remove the tank lid and remove the valve. Inspect, test, and replace as needed. * Drain the hydraulic oil, remove the tank lid, and inspect for any issues. Repair as needed and remove any debris. * Inspect and repair as needed.
Why does the chain on my Barreto Excavators fail to rotate, even though the wheels are driving?
If the chain on your Barreto Excavator fails to rotate while the wheels are driving, consider these steps: * Check the digging chain valve adjustment and adjust the controls or push rod. * Rebuild or replace the motor with a new one. * Replace any worn parts as needed. * Inspect the relief valve spring for any breakage. To set the relief valve, disconnect the hose from the chain control valve and install a 4000 psi pressure gauge on the valve port. Start the engine and manually move the chain valve lever to the “FORWARD” position. Adjust the relief valve (located on top of the chain valve) so that relief is activated at 3000 psi, or when the engine stops.

The Barreto Models 1324D and 1624D are hydraulic trenchers designed for digging trenches in various ground conditions. This owner's manual provides comprehensive information for operation, maintenance, and troubleshooting to ensure safe and efficient use of the equipment.
The primary function of the Barreto trencher is to dig trenches. It utilizes a hydraulic system to power a digging chain, which is equipped with teeth for cutting through soil and small stones. The machine is designed for use in "normal" ground, which typically includes reasonably soft dirt and stones up to 6 inches (15 cm) in diameter. For harder ground conditions, such as those with larger stones, high clay content, very hard-packed soil, very dry soil, or frozen ground, the manual suggests considering alternative, heavier equipment like a backhoe.
The trencher features a boom that can be lowered into the ground, and the digging chain rotates around this boom to excavate the trench. The machine also includes a wheel drive system, allowing it to move forward and backward during trenching operations. Control levers on the handlebars enable the operator to manage the digging chain's movement (forward, neutral, reverse) and the wheel drive speed.
The Barreto trencher is designed with several features to facilitate its operation:
Routine maintenance is essential for the longevity and safe operation of the Barreto trencher. The manual outlines several key maintenance tasks and considerations:
The manual also includes a "Machine Identification Record" section for users to fill in details like machine model and serial numbers, and engine manufacturer, model, and serial numbers, which is useful for future reference and parts ordering.
