1. At the site where the rig is used, obstacles such as holes and surrounding stones should be removed as required by the rig manual.
2. The distance between the work site and the power transformer or the main power supply line should be within 200m, and the voltage drop during start-up should not exceed 10% of the rated voltage.
3. The motor and control box should have a good grounding device.
4. Before installation, check and confirm that there is no deformation of the drill pipe and components; after installation, the centerline of the drill pipe and power head allows the deflection to be 1% of the full length.
5. When installing the drill pipe, start from the power head and install it from section to section. The length of the required drill pipe must not be fully connected on the ground before lifting.
6. Before the power head is installed, the pulley block should be removed and the steel wire rope should be wound. The selection of wire rope should be equipped with the requirements specified in the instruction manual.
7. After installation, the frequency of the power supply should be the same as that on the frequency conversion switch in the control box. When it is not the same, the frequency conversion switch should be used to convert it.
8. The drill rig should be placed in a stable and firm manner. The auto drill should have its legs erected, and the tires should be lifted. The lifter should be adjusted automatically or by using a line trimmer to keep it vertical.
9. Before start-up, it is necessary to check and confirm that all components of the drill rig are firmly connected, the tightness of the transmission belt is appropriate, the oil level in the gearbox is in compliance with the regulations, and the drill depth limit alarm device is effective.
10. Before starting, put the joystick in the neutral position. After start-up, the test should be made empty and the work of the instrument, temperature, sound, and brakes should be normal.
11. When drilling, you should first slowly lower the drill pipe to align the drill bit with the hole position. When the current meter pointer is biased to the no-load state, you can drill it down. During drilling, when the ammeter exceeds the rated current, the drilling speed should be slowed down.
12. When the drilling rig issues a drilling limit alarm signal, it should stop drilling and raise the drill rod slightly. After the alarm signal is released, drilling can continue.
13. When stuck in the drill hole, immediately cut off the power and stop drilling. Before the cause can be ascertained, it must not be forcibly started.
14. During operation, when the direction of rotation of the drill pipe needs to be changed, it should be performed after the drill pipe is completely stopped.
15. When drilling, when the rack shakes, moves, skews, or rhythm sounds in the drill bit, stop the drill immediately and treat it before continuing drilling.
16. When the hole is expanded to the required hole diameter, the expansion should be stopped, and the hole-reaming knife pipe should be pulled together. The hole should be loosened a few times, so that all the memory soil can be transferred to the ground and the drill can be stopped.
17. In the event of a power outage in the operation, each controller should be placed in a zero position, the power supply should be cut off, and the drill pipe should be pulled out of the hole in time so that the drill bit contacts the ground.
18. When the drilling rig is in operation, cables should be prevented from being tangled in the drill pipe. Special personnel must be provided for care.
19. When drilling, it is forbidden to remove the dirt in the spiral by hand. When the tightening bolts are found to be loose, they should be stopped immediately, and the work can be continued after tightening.
20. After the hole is formed, the hole should be covered and protected.
twenty one. After the operation, the drill pipe and drill bit should all be lifted to the outside of the hole. First remove the drill rod and the dirt on the spiral blade, then press the drill bit to touch the ground, the various parts are braked, the joystick is placed in the neutral position, and the power is cut off.
twenty two. When the drill wear reaches 20mm, it should be replaced.
2. The distance between the work site and the power transformer or the main power supply line should be within 200m, and the voltage drop during start-up should not exceed 10% of the rated voltage.
