Attention:
1. Use genuine 2T (two-stroke) engine oil and strictly prohibit the use of 4T (four stroke) engine oil.
2. It is strictly prohibited to use pure gasoline.
3. Strictly mix oil in a ratio of 25 to 1 (1 liter of gasoline to 40 milliliters of engine oil). Mixed oil should be used up on the same day, and mixed oil that has deteriorated and turned red should not be used.
4. The new machine cannot be used at high speed. Please run in at low speed for 3 hours (equivalent to 5 pots of oil).
To extend the lifespan of the machine, take a 10 minute break every half hour of work.
6. It is strictly prohibited to suddenly shut down the engine at high speeds, otherwise it will make it difficult to start the next time.
7. If you feel that the machine is vibrating abnormally, please stop it immediately and check if it is damaged, loose, or eccentric.
8. It is strictly prohibited to use it on grassland with disorderly stone piles.
9. There are strict size restrictions on drill bits, and it is strictly prohibited to modify or use enlarged drill bits without authorization. If you need other types of drill bits, you can contact me directly.
10. Clean the spark plugs and carbon deposits on the muffler every 50 hours of work, replace the oil filter, and add gear oil to the gearbox.
11. If you encounter problems that you cannot solve on your own, please contact me and do not disassemble or assemble them without authorization.
12. Safety precautions:
A. Personal safety: It is strictly prohibited to add gasoline indoors to prevent fires; During machine operation, it is strictly prohibited to approach the drill bit with hands and feet; The machine must be stopped when cleaning or inspecting.
B. Machine safety: Before starting the drilling machine, the debris on the lawn must be cleaned to ensure safe operation of the machine.
When the machine is not in use for a long time, the remaining fuel should be poured out and then the machine should be started to burn all the fuel completely.
14. If you want the machine to operate more stably and have a longer lifespan, please maintain it regularly (see instructions for details).

Drilling machines are mainly used for hole shaped soil preparation before planting trees, for digging fertilizer holes or burying pile pits for plants, for fertilizing plants, for crop supports such as grapes, kiwifruit, bananas, and windbreak holes. Drilling machine, also known as digging machine.

There are mainly two types of drilling machines: portable and suspended; There are two types of portable devices: handheld and backpack. Handheld and suspended use are more common. A portable excavator consists of an engine, clutch, reducer, drill bit, and control device.

The drilling machine engine adopts a two-stroke air-cooled gasoline engine with a power of 2 kilowatts, and its power drives the drill bit through a clutch and reducer for operation. A clutch is a connecting device between an engine and working components, typically using a centrifugal friction clutch. When the engine reaches a certain speed, the centrifugal force generated by the clutch active disc hammer overcomes the tension of the spring, and the clutch automatically engages and transmits power to the drill bit through the reducer.

The reducer of the drilling machine is an important component of the excavator, which functions to convert the engine speed into the working speed of the drill bit. There are types of reducers, such as cylindrical gear reducers, worm gear reducers, and cycloidal pin gear reducers. It is common for excavators to use cycloidal gear reducers, which have the characteristics of large reduction ratio, small size, light weight, low noise, and smooth transmission. The control device often adopts a handle structure, which can be operated by one or two people.

During the operation of the drilling machine, the drill bit moves vertically downwards, cutting the soil under the action of torque and axial force. The loose soil cut rises along the working face of the soil guide plate and is thrown away around the pit after being transported to the surface. Drill bits are divided into three types based on the shape of the soil guide and blade: spiral, blade, and curved. The drill bit can also be equipped with a drill rod sleeve and a protective cover to prevent the drill rod from being entangled by grass and provide safety protection. In order to enable the excavator drill bit to automatically excavate, the machine is often equipped with a reversing mechanism. The rotation speed of the drill bit is designed more reasonably to ensure that the soil lifted out will not be thrown too far, and to facilitate the backfilling and burial of plants such as saplings.
