    Operating instruction

    ★1 Before operation, ensure that the working systems of the mixer are working properly and are safe and free from the surrounding environment.

    *2 The driver is dressed neatly, enters the cab in the correct way, adjusts the seat position, opens and drives the mixer, the cab is fully equipped, equipped with air conditioning system, radio, and joystick designed according to ergonomics, operation Simple, lightweight and flexible.

    ★3 After the water tank is flooded, the driver controls the bucket with the joystick, loads the bucket sand, and then pours the cement into the bucket. The bucket insert can easily cut the cement outer packaging to avoid waste of raw materials. Then, using the fluidity of the sand, the cement is brought into the drum and then loaded into the aggregate. The electronic weighing system can accurately control the ratio of the ingredients, aggregate, sand, and cement into the mixing drum, and automatically pressurize and mix with water through the water tank. Make it more evenly stirred.

    ★4 Driving the mixer to the construction site, the SYNBON mixer can prevent rollovers from falling, suitable for any site operation, providing safe and reliable protection for the actual situation, and equipped with a four-wheel steering drive system to enable the vehicle to be in a harsh construction environment. Driving on complex roads, the efficiency diversion system can ensure that the drum is always in a state of agitation during transportation, ensuring that sand and gravel do not settle and ensure the quality of the concrete.

    ★5 Using the joystick to pass the 290° rotary mixing drum, the concrete can be dumped at a height of 120 cm to 160 cm. During the unloading process, the mixer can move back and forth according to the actual situation.

    ★6 After the end, use the automatic flushing function of the mixer to thoroughly rinse the mixing drum. Use the automatic flushing function of the mixer to thoroughly rinse the mixing tank to ensure no residue in the tank.

    ★7 Regularly use the automatic lubrication function to carry out daily maintenance of the vehicle. The SYNBON mixer is dedicated to providing customers with the best solution for mixing and pouring concrete. The lightweight and flexible body is ideal for construction in crowded urban areas, mountains and fields.
