How is the parking brake on the MHU-83 lift truck set?

The parking brake on the MHU-83 lift truck is set by closing the locking valve and then depressing the brake pedal. This action effectively holds the truck in place by maintaining pressure within the braking system. The locking valve prevents the flow of hydraulic fluid, which is essential for the brake function. When you close the valve, it secures the brake system, and by depressing the brake pedal, you activate the brakes, ensuring that the lift truck remains stationary until you are ready to move it again. This method is crucial for safety, especially when the truck is loaded and parked on an incline. The other methods involve actions that do not directly apply to the MHU-83's designated parking brake system.
