Maintenance method
1. Avoid impact pressure damaging components
Impact pressure in the hydraulic pressure should be avoided during operation, as impact pressure will damage components. Each pressure valve and each flow valve must be reasonably adjusted strictly in accordance with the design requirements. After adjustment, the adjusting screws must be tightened securely.
2. Always pay attention to the temperature of the hydraulic station
The working temperature of the hydraulic system oil must not exceed 70°C, and should generally be controlled within the range of 35~60°C. If it exceeds the specified range, the cause should be checked and eliminated.
3. Maintain the quality of hydraulic oil
Select hydraulic oil according to the brand number specified in the instruction manual. The oil must be filtered before refueling. At the same time, the oil quality must be sampled and tested regularly. If the oil quality is found to be unsuitable for use, it must be replaced. Generally, it must be replaced every six months or every 2,000 working hours.

Theory
There are two ways to brake the swing motor: parking mechanical brake and hydraulic brake. The parking mechanical brake is installed inside the motor and mainly consists of a spring, a brake piston and a brake friction plate. Pp solenoid valve lock state mechanical brake control:
The input oil at the motor slack port Pp is pilot pressure oil and is controlled by the rotary lock solenoid valve. When the solenoid valve is locked, the Pp port pressure is released, and under the action of the brake spring force, the brake piston tightens the brake friction plate to realize the parking mechanical braking function.
