4. Setup

The HUAYEE HY12C Mini Excavator is typically delivered with professional unloading services. Upon arrival, perform the following checks before initial operation.

4.1 Pre-Operation Checks

1. Fluid Levels: Check engine oil, hydraulic fluid, and fuel levels. Ensure they are within the recommended range. Refer to the specifications section for capacities.
2. Fueling: Use only unleaded gasoline. The fuel tank capacity is 6.6 liters.
3. Battery: Ensure battery terminals are clean and securely connected.
4. Track Tension: Verify the rubber track tension is correct. Adjust if necessary according to maintenance guidelines.
5. Attachments: Confirm the digging bucket and hydraulic thumb are securely attached.
6. Controls: Test all control levers and pedals for smooth operation and responsiveness.

5. Operating Instructions

Understand the controls and functions before operating the excavator. Always operate from the operator's seat.

5.1 Starting the Engine

1. Ensure the parking brake is engaged and all control levers are in the neutral position.
2. Turn the ignition key to the 'ON' position.
3. If the engine is cold, apply choke as needed.
4. Turn the ignition key to the 'START' position. Release once the engine starts.
5. Allow the engine to warm up for a few minutes before operating.

5.2 Basic Operation

• Driving: Use the foot pedals or hand levers (depending on configuration) to control forward and reverse movement of the tracks.
• Boom and Arm: Use the right joystick to control the boom (main lifting arm) and the arm (secondary arm).
• Bucket: Use the left joystick to control the bucket curl and dump.
• Swing: The upper structure can rotate 360 degrees. Use the dedicated swing control (typically a foot pedal or a lever) to rotate the cabin and boom assembly.
• Dozer Blade: Use the dozer blade control lever to raise or lower the front blade for leveling or stabilization.

5.3 Using the Hydraulic Thumb

The hydraulic thumb allows for grasping and moving objects that cannot be scooped by the bucket alone.

1. Position the excavator so the object is within reach of the bucket and thumb.
2. Lower the bucket to approach the object.
3. Use the dedicated hydraulic thumb control (typically a foot pedal or auxiliary joystick button) to close the thumb towards the bucket, gripping the object securely.
4. Carefully lift and move the object to the desired location.
5. Release the thumb to drop the object.
