Preparing to work on a front-end loader
To ensure safe and efficient operation of a front loader, training should be carried out in a standardized and consistent manner. Pay particular attention to two aspects.
1. Preoperative check-up
In addition to assessing the conditions of the work site, carefully inspect the equipment's appearance, hydraulic system, powertrain, and controls to eliminate potential hazards.
Worksite inspection
Check for overhead power lines, obstacles, holes or uneven ground. Make sure all personnel have left the work area.
Checking the appearance of the equipment
Inspect the machine body for dents or deformations; check the bucket and boom for wear or cracks; check the tire pressure (for track loaders, track tension).
Checking the hydraulic system
Check hydraulic hoses and connections for leaks; make sure the hydraulic oil level is within normal limits and the oil is clean.
Powerplant check
Check engine oil, coolant and fuel levels; clean the air filter element; make sure the battery is connected securely.
Inspection of management bodies
Before starting, check that the control levers and pedals move smoothly and without binding; make sure that the indicator lights and displays are working properly.
2. Safe forklift start
After completing the pre-operational checks, the operator must start the equipment in a safe and standardized manner. Follow the steps below.
Preparing for landing
Wear personal protective equipment (PPE): a hard hat and non-slip shoes. Maintain balance when opening the door to avoid falling. Use the “three-point support” method when boarding – both hands and feet should touch the handrails or footrest of the equipment for stable entry into the cabin.
Pre-launch settings
Fasten your seat belt and other restraints; adjust the seat and steering wheel to a comfortable position; make sure the transmission is in neutral; close the cab doors and windows to reduce dust inside.
Starting and warming up
Insert the key into the ignition to start the engine. Allow it to idle for 3 to 5 minutes to warm up (warm-up time will increase in cold conditions).
Post-launch check
After the engine has warmed up, check the surrounding area again. Only after making sure that there are no safety hazards, release the parking brake and prepare for work.
Step-by-step procedure for working on a front-end loader
From a practical perspective, the key to operating a front-end loader is to perform operations in a standardized and consistent manner with meticulous attention to every detail.
1. Movement and positioning
Traffic management
Control acceleration and braking with the pedals and direction with the left joystick or steering wheel to safely move the machine into the work area. Control your speed while driving, especially avoiding sudden starts and sharp turns.
Positioning
Before starting work, adjust the distance between the machine and the material, taking into account the location of the pile and the boundaries of the work area. Make sure that the center line of the bucket is aligned with the center of the pile of material.
2. Capture, transport and unloading
Capture operation
With the bucket cutting edge horizontal, drive straight into the pile of material, slowly bringing the bucket to the ground, and raise the boom slightly to maintain traction. After filling the bucket, fold it in while pulling the boom back. To grab large pieces or hard soil, insert the bucket gradually.
Transportation operation
After grabbing, before backing away from the stack, level the bucket and lower the boom. Then drive to the unloading location at a steady speed.
Unloading operation
As you approach the dump point, raise the boom. Then slowly move forward and dump the material. After unloading, return the bucket to its original position, slowly lower the boom, and prepare for the next cycle.
3. Digging and soil development
In the absence of an excavator, a front-end loader can effectively develop solid structures and dig hard soil, gravel, or shallow trenches through the coordinated use of the boom and bucket.
Positioning and penetration
Position the machine in front of the digging point. Adjust the bucket so that its base is on the ground and tilt it forward, inserting the cutting edge into the soil.
Digging and loading
Move forward, digging the bucket into the soil and tilting it to load. Raise the bucket off the ground and drive away with a full load. If digging cannot be done in one pass, penetrate and develop the material in stages.
Unloading of material and further operations
Transport the material to the designated location, raise the boom and dump. Lower the bucket, return to the work area and repeat the steps described.
4. Planning and leveling
With the help of a bucket, a front-end loader can scrape or move gravel, mulch, and soil to effectively level and clear the surface.
Clearing operation
Mark and pre-clear the work area, removing mainly weeds, bushes, trees and large rocks. Load materials into the bucket to balance the equipment.
Alignment operation
Keep the bucket parallel to the ground and move forward. Repeat the operation, cutting off the raised areas and leveling the mulch. For dragging operations, lower the bucket to the ground and move in reverse to level the surface. Repeat until the desired ground level is reached.
5. Proper completion of work
After completing daily operations, properly parking the equipment in the appropriate location is a key practical aspect of operating a front-end loader.
Preparing for parking
Park the equipment on a level, safe parking area away from hazardous areas such as piles of material and excavations. Engage the parking brake, return the bucket to its home position, lower the boom, and place the bucket base on the ground.
Parking and post-inspection
Stop the engine and remove the key. Check for oil or coolant leaks and remove debris from the cab. After confirming safety, exit the cab and close all doors and windows.
Important Note: Control methods may vary depending on the type of front loader. Always refer to the specific equipment’s operator’s manual. Wheel loaders, backhoe loaders, and skid steer loaders have different operating characteristics, so it is important to learn the relevant control differences before operating each machine.

What can't you do with a front-end loader?
Understanding the operating prohibitions for a front loader is a prerequisite for ensuring safety. In particular, the following high-risk actions are strictly prohibited.
Do not overload the bucket.
An overloaded bucket shifts the machine's center of gravity forward, which can cause it to tip over.
Do not stand or work under the bucket.
Whether the bucket is loaded or empty, the space underneath is a high-risk area. A sudden hydraulic leak or operator error can cause the bucket to fall.
Do not raise or lower the bucket abruptly.
Rapid lifting, lowering or sudden tilting of the bucket can easily cause material spillage and personal injury. It also puts stress on the hydraulic system and frame, which can lead to equipment failure or loss of stability.
Do not travel at high speed with the bucket raised.
Driving with the bucket raised above a safe height significantly raises the machine's center of gravity, making it prone to tipping over when cornering or encountering obstacles.
