John Deere 120R Operator's Manual

Ensure the tractor is on a level surface. Align the loader's mounting frames with the tractor's mounting brackets. Gradually drive the tractor forward until the loader is fully engaged. Secure the loader with the locking pins and connect the hydraulic hoses.
Inspect the loader before each use. Check hydraulic fluid levels and inspect hoses and connections for leaks. Lubricate pivot points every 10 operating hours and perform a comprehensive inspection annually or every 200 hours.
Check for leaks in hydraulic lines and ensure all connections are tight. Verify that the hydraulic fluid level is adequate and that there are no obstructions in the hydraulic system. If problems persist, consult the service manual or contact a professional technician.
Inspect the hydraulic fluid level and replenish if necessary. Check for leaks or damaged hoses. Ensure that the hydraulic filter is not clogged and that the hydraulic pump is functioning correctly.
Park the tractor on a level surface and lower the loader to the ground. Disconnect the hydraulic hoses and remove the locking pins. Slowly back the tractor away from the loader until it is completely detached.
Always drive at a safe speed and avoid making sharp turns. Keep the loader as low as possible to maintain stability. Be cautious of slopes and maintain a safe distance from edges and drop-offs.
Consult the operator's manual for specific adjustment procedures. Generally, you can adjust the loader's position and angles using the hydraulic controls to match the task requirements, such as digging or lifting.
Look for cracks or bends in the loader arms, leaks in hydraulic hoses, and worn pivot points. Additionally, check for unusual noises during operation, which may indicate the need for maintenance.
Plan your work to minimize unnecessary movements. Regularly maintain the loader to prevent downtime. Use the loader at its optimum capacity and ensure the attachments are appropriate for the task.
Store the loader in a dry, sheltered location to protect it from the elements. Lower the loader to the ground to relieve hydraulic pressure. Inspect and clean the loader before storage and periodically check for any signs of wear.
