The Barreto Model 825TKL Skid Loader is a compact track loader designed for light and medium-duty construction and landscaping tasks. It is built to attach to industry-standard tools and implements, offering versatility for various job site needs.

Function Description:

The 825TKL Skid Loader primarily functions as a compact, track-driven machine capable of operating a wide range of hydraulic attachments. Its main purpose is to assist in tasks requiring earthmoving, material handling, and other specialized operations through its attachment system. The operator stands on a ride platform, controlling the machine's movement and attachment functions via joysticks and a display panel. The machine is equipped with a safety system that disables functions if the operator steps off the platform.

Usage Features:

• Operator Controls: The machine features a user-friendly control layout with a track drive joystick for movement and a lift arms/tilt joystick for attachment manipulation. An engine throttle and ignition switch are also present.
• Display Panel: An integrated display panel provides critical information and warnings regarding machine and engine operation. It shows data such as engine coolant temperature, fuel level, battery voltage, hour meter, and glow plug status. Warnings are displayed in red, while normal operational information is in blue.
• Auxiliary Tool Control: The display panel includes buttons to enable auxiliary tools, categorized into "Low-Flow" (Tool 2) and "High-Flow" (Tool 1) attachments. The lift arm joystick has two buttons for controlling these tools, allowing for forward or reverse flow.
• Speed Selection: The track drive speed can be adjusted via the display panel, offering "High," "Mid," and "Low" options for better control in various operating conditions or with different attachments.
• Attachment System: The 825TKL uses an industry-standard attachment plate with two lock pins to secure implements. The process involves tilting the attachment plate, driving into the attachment's pocket, and then tilting upward to engage the lock pins.
• Float Action: Pushing the right-hand lever fully forward enables a float action for the lift arms, allowing attachments to follow ground contours.
• Operator Presence Switch: A safety feature on the ride platform disables all machine functions if the operator steps off, ensuring the operator is always in control.
• Cold Weather Operations: Specific procedures are outlined for operating in cold weather, including engine warm-up and hydraulic fluid considerations. The machine is equipped with an automatic glow plug warmer for easier starts below 140°F (60°C).
• Operational Inclines: The machine should not be operated on side hills greater than 20° to prevent tipping.
• Emergency Towing: The 825TKL can be towed short distances in case of engine failure by bypassing the hydrostatic pumps. This involves loosening specific bypass plugs to allow the tracks to move freely.
• Road Transport: Detailed loading and unloading procedures are provided for transporting the 825TKL on a trailer, emphasizing secure tie-down points and proper weight distribution.

Maintenance Features:

• Grease Points: The manual highlights specific grease points, recommending lubrication every 10 hours of operation for components like lift cylinders, tilt cylinders, tool pivots, tool pins, idlers, and rollers.
• Battery & Electric Starter Safety: Detailed instructions are provided for safe handling of the battery, including precautions against sulfuric acid and flammable fumes during jump-starting or maintenance.
• Engine Manual: Operators are directed to the Kubota Engine Manual for specific engine maintenance instructions.
• Hydraulic System: The manual advises checking hydraulic fluid levels and warming up the fluid in cold weather to prevent pump damage.
• Oil Pressure Light: Operators are instructed to check the oil pressure light after starting; if it remains on, the engine should be turned off immediately to determine the cause.
• Cool-Down Procedure: Before refueling or performing cleaning/maintenance, the engine and hydraulic components must be allowed to cool completely to prevent burns.
