Part of the Kubota Operator Manuals.
This Kubota Operator Manual covers the LA272, LA302, LA352, and LA402 front loaders across all 36 pages. It is the factory operator handbook for owners and independent mechanics who want to set up, run, and maintain these loaders correctly instead of guessing.
Inside you get the full specifications and performance charts, setting-up and mounting instructions, pre-operation checks, and step by step operating technique for filling, lifting, carrying, dumping, and float control. Maintenance, lubrication intervals, and the loader removal, storage, and reinstallation procedures are all documented, along with the hydraulic block and main frame torque figures.
Whether you are attaching the loader for the first time, bleeding air from the hydraulics, or chasing a slow lift, this manual gives you the model specific numbers and procedures. Download it as a PDF and print any page you need at the workbench.

| Hydraulic leak troubleshooting | Visually check for hydraulic leaks and broken, missing, or malfunctioning parts. Make necessary repairs before operation. Inspect all hoses for cuts or wear and ensure all fittings are tight. Before disconnecting lines, relieve all hydraulic pressure. Do not use hands to search for suspected leaks; use cardboard or wood. If injured by escaping fluid, obtain medical treatment at once. | p. 30 |
| Mounting hardware torque guidance | Tighten all bolts and nuts in the following order to the required torque as specified in the 'Tightening Bolts and Nuts' table on page 22. Do not tighten any bolts firmly until most components are attached to the tractor. Before final tightening, apply down pressure to the bucket until the loader raises the front wheels slightly, and ensure mounting pins can be rotated easily. | p. 22 |
