1. Placement and environment: The shaker should be placed on a flat ground or a sturdy tabletop, avoiding direct sunlight and keeping the room dry. The environment should be clean and tidy, with good ventilation.

2. Power Supply and Grounding: Power sockets should have good grounding devices, and the instrument switch should be turned off before plugging in the power plug.

3. Preparation before operation: Before use, place the speed control knob in the minimum position and turn off the oscillation switch. When setting the speed, please pay attention to the fixed form of the experimental bottle. Excessive speed may cause the spring net to fail to restrain the experimental bottle and lead to accidents.

4. Liquid filling and test bottle: When filling the culture test bottle, it should be evenly distributed, and the amount of liquid filled should not be too small to prevent the test bottle from floating; Seal the bottle mouth to prevent condensed water droplets from dripping into the bottle.

5. Water injection and quality: Inject tap water into the water tank, and the water level should be slightly higher than the liquid level inside the cultivation test bottle. Do not use hard water such as well water, river water, spring water, etc. to prevent the heating tube from bursting and affecting the sensitivity of constant temperature.

6. Safety and maintenance: It is prohibited to use heaters in a water tank without water. If the water bath constant temperature oscillator is not used for a long time, the water in the water tank should be drained and wiped dry with a soft cloth. It is strictly prohibited to move the machine or hit the water bath thermostatic oscillator during normal operation, and children are strictly prohibited from approaching the machine. Before replacing components for maintenance, ensure that the power supply has been cut off.

7. Exception handling: If any abnormal phenomenon is found after turning on the machine, immediately unplug the power plug and seek professional inspection
