Figure 5.1: The front joystick controls, providing precise and reliable operation for the boom, arm, bucket, and swing functions. Familiarize yourself with the control pattern before operating.

• Left Joystick: Typically controls the swing of the boom and the movement of the arm.
• Right Joystick: Typically controls the boom lift/lower and bucket curl/dump.
• Foot Pedals: Control track movement (forward/reverse) and auxiliary hydraulic functions (if equipped).
• Throttle: Adjust engine RPM for desired power and speed.

5.3 Moving the Excavator

Use the foot pedals to control the movement of the tracks. The excavator moves slowly, which enhances stability, especially on uneven ground.

Figure 5.2: The all-terrain tracks provide excellent traction across various challenging surfaces, including loose soil, rocky paths, and muddy areas.

• Ensure the area is clear of obstacles and personnel.
• Gradually engage the track pedals to move forward or backward.
