Step 1: Inspection

1. Unpack and Inspect: Open the package and compare the contents with the container load plan. Inspect the

machine and parts for any damage that may have occurred during transportation.

2. Voltage Check: Ensure that the voltage at the job site matches the voltage indicated on the machine’s

3. Accessory Check: Verify that all attachments listed in the container load plan are included in the package.

Step 2: Connecting the Power Source

1. Compliance with Standards: According to European Union standards EN61029 and IEC1029-2-6, diamond

drilling machines used for wet operations must be equipped with a residual current device (RCD) to protect against electrical leakage. Ensure that the power socket is properly grounded.

2. RCD Protection: Our product comes equipped with an RCD, which includes protection against electrical leakage

and under-voltage release. After plugging in the power source, ensure that the RCD’s switch is in the "ON" position.

3. Voltage Drop: If a voltage drop occurs, the RCD will automatically disconnect the power. Once the voltage

returns to normal, reset the RCD by pressing the "RESET" button. The specified operating current for the RCD is 30mA.

4. Water Source: Ensure the water source is clean and free from impurities like grit, which could damage the

machine’s water seals. The maximum allowable water pressure is 3 BAR. Step 3: Connecting the Water Source

1. Water Inlet Connection: The machine is equipped with a flexible water inlet tube with a "quick joint," making it

easy to connect to a wire-reinforced suction hose in the water supply system. Step 4: Safety Testing

1. Initial Testing: Press the generator switch and the machine’s soft start switch to ensure smooth operation.

2. RCD Testing: Press the "TEST" button on the RCD. The machine should stop operating, indicating that the RCD

is functioning properly. After the test, restore power to the machine by pressing the "RESET" button on the RCD.

3. Water Safety: Never submerge the RCD in water. Regularly test the RCD by pressing the "TEST" button to

ensure it is functioning correctly. Final Note: If the RCD does not function properly, do not use the machine. Operators should not operate the diamond drilling machine without a functioning RCD.Steps for Using the Diamond Drilling Machine

1. Choose a Suitable Diamond Bit

• Select the Right Bit: Our company's main shaft supports four commonly used types of bits. Choose a high-quality diamond bit that is sharp and suitable for the task.

• Ensure Clearance: Ensure that the diamond bit has enough clearance between the thickness of the bit head and the tube wall, which helps with bit alignment. The bit should have a backlash (clearance) that is larger than the tube wall thickness to ensure smooth operation.

• Bit Preparation: Apply waterproof oil paint to the bit to facilitate easier bit removal later. Ensure that the bit’s radial runout (eccentricity) does not exceed 1 mm.

• Fixing Methods: Common methods to fix the frame include using expansion bolts, vacuum suction, or regular supports. o Expansion Bolts: The most common method is using expansion bolts. Ensure the diameter of the metal expansion bolt and the bolt itself is at least 12 mm. o Vacuum Suction: If using vacuum suction, ensure that the vacuum pump is efficient and that the sealing ring is intact and undamaged. o Support Stands: When using support stands, ensure that the frame is stable.

• Frame Alignment: If using expansion screws: o Ensure the surface and the base of the machine are level. If the base is not level, use the spanner included with the machine to adjust the four adjustment screws on the base until it is balanced. o After fixing the machine, make sure the generator does not slide on the rack. Pull and move the pillar to ensure it does not sway or move when using the machine.

• Recommendation: We strongly recommend using expansion bolts for securing the frame. Position the expansion screws as close to the pillar as possible for optimal stability. The company is not liable for any issues resulting from improper securing of the machine.

• Qualified Operation: This rig should only be operated by trained professionals. It is suitable for drilling holes in materials like rock, reinforced concrete, and asphalt, or for core drilling. Always follow the operation instructions carefully.

• Water Supply: Ensure adequate water is supplied through the ball valve to thoroughly flush away debris. If the machine is filling with a mud-water mixture, it indicates insufficient water supply. o Feed Pressure: Apply the appropriate feed pressure as required. Insufficient pressure may cause the diamond tip of the bit to wear down, significantly reducing drilling efficiency. Occasionally, the bit may require additional adjustments when cutting harder materials like SIC (silicon carbide) to prevent vibration and ensure the diamond remains intact. o Metal Cutting: When encountering metal, switch to a lower speed and increase the feed pressure. o Obstruction: If the bit becomes stuck, do not force the machine to continue. Immediately stop the machine and use a spanner to carefully loosen the bit before resuming drilling.

• Vertical Drilling: When drilling upwards, use a special water collection basin to prevent water from entering the generator. If the machine stops unexpectedly, restart it only after ensuring that the bit can turn freely and is not obstructed in the holeMASTER SWITCH AND OVERLOAD PROTECTIVE DEVICE

The clutch is designed to provide protection for the operator, machine, and bit under high- strength mechanical overload conditions. However, to prevent damage, ensure that the clutch remains in a disengaged state for no more than 3-4 seconds when under load. Prolonged disengagement can cause a rapid increase in temperature, leading to wear on the friction plates.

• After pressing the switch, the machine (soft start switch) will start smoothly. If the machine becomes overloaded, the electronic protection switch will alert the operator to the overload with noticeable fluctuations. If the load is not reduced, the switch will automatically shut off after a few seconds. Once the load is removed, the machine can be restarted, and it will again start smoothly.

• Before restarting, ensure that the bit can turn freely and is not blocked in the drill hole. If the machine is subjected to a voltage higher than 260V, it can cause severe damage, potentially burning out the generator. When using a generator to supply power, make sure that the voltage peak does not exceed 260V.

3 files To improve the efficiency of drilling, machines have 3 types of gear speed changes. In it is high to divide, high speed files (H) apply to little bit and more soft material to rush, fast files (M) apply to in bit and more hard material; The files of low speed (L) apply to big bit and hard material. To improve drilling efficiency, machines feature a three-speed gear system:

• High Speed (H Gear): Suitable for small bits and softer materials.

• Medium Speed (M Gear): Ideal for mid-sized bits and harder materials.

• Low Speed (L Gear): Best for large bits and very hard materials. Gear Shifting Instructions:

1. Shifting Gears: Always shift gears when the machine is stopped or nearly stopped.

2. Proper Gear Engagement: When shifting, ensure the gear is fully engaged. If, after starting the machine, the

main shaft does not rotate or you hear a grinding noise, it indicates that the gear did not fully engage. Immediately turn off the machine, and while turning the main shaft back and forth, move the gear knob to the desired position until the gear engages properly.

3. During Operation: Never attempt to change gears while the machine is running at full speed, under load, or if

the bit is jammed. Always stop the machine before shifting gears to avoid damage. This process helps ensure the gear is correctly engaged and prevents damage to the machine.

1. Cleaning the Machine:

o Use a rag to clean the machine. Do not use water to spray or wash the machine. o Ensure that water does not enter the generator or switch box. o Keep the air-breather clean and unblocked. o Clean the main shaft and apply oil to it.

2. Lubricating the Gear:

o After 300 hours of operation, the gear lubricating oil should be changed by a professional following these steps: Ensure the machine is fixed vertically (with the main shaft facing down). Loosen the 36 angle screws on the gear case shell and remove the generator and intermediate cover. Replace the gear lubricating oil with the brand specified by the manufacturer. Reassemble the machine in the correct order and ensure everything is properly installed. o Caution: If you notice any lubricating oil leakage, immediately stop using the machine to prevent damage to the gears.

3. Water Set Sealing Ring:

o If cooling water leaks from the water set, replace the sealing ring immediately. This task should be performed by a professional at an authorized repair station.
