1, hydraulic safety lock switch
You can see it when you open the door of the excavator. As the name implies, the "safety lock" is designed with the driver's safety in mind. Because the action of the excavator is driven by hydraulic pressure, the safety lock can control the transmission of hydraulic pressure in time. When the excavator is started, the driver sits in the seat and turns the hydraulic safety lock to the unlocked state. At this time, the operating handle or walking pedal excavator will act accordingly.
2. Main switch of power supply
Before starting the excavator, be sure to check whether the main power switch of the excavator is turned on. When the excavator is not working for a long time, it is necessary to turn off the main power supply to prevent the battery from leaking. On the excavator, even if the key of the excavator is pulled out, the emergency light and radio on the roof are still powered on, and they can all be turned off by turning off the main power switch.
3. Engine start switch
When the driver enters the cab, insert the key from the keyhole and turn it to the ON position. At this point, the power supply is turned on. After the dashboard lights up, turn it to the start position and start the engine. When the air temperature is cold, it may be difficult to start because of the increase of oil viscosity and the decrease of battery performance. Therefore, please try to start the engine successfully at one time and make the idle engine warm.
I believe everyone can see the process of starting and shutting down at a glance. What I want to say here is the importance of preheating, which is exactly the process that most drivers will ignore. Under normal circumstances, the engine should be warmed up after starting, especially when the weather is cold and the water temperature is relatively low. Warm-up is to start the machine first, wait for the temperature of the machine and the "running-in" between components, and then let the machine enter the working state.
4. Dashboard
Excavators can choose different working modes in operation: S standard mode: H heavy digging mode; L renovation mode; F minor repair mode. Like other excavators, it has strong P/H working mode and standard M/S mode. E economic model and so on.
